SEINE IN FISHING?<o:p></o:p>

Introduction                                                                                                                                        The use of seine nets in the fishing industry is an
age-old practice that has been with the human race for centuries. Today, it is
not uncommon to see seine nets being used in the industry. <span style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; color: #333333; font-family: Calibri, sans-serif; font-size: large;">A seine net is a type of fishing net that is vertically
hanged in the water. In order to keep it floating, weights are attached to the
bottom edges. It is the type of fishing gear mostly used in shallow waters to
capture fish. Seine nets can be used in rivers, oceans and at the shorelines of
lakes. This is how the seine net is employed; Two groups of people, holding
either side of the net, pull the net in a circular motion. The aim is to
encircle the fish. Once the net is encircled, it is drawn to the shore. It is
here that the catch is collected. The net is then drawn to the shore, where the
catch can be collected. In this article, we will discuss the merits and
demerits of the use of seine nets in the fishing industry.

Allows for selective fishing                                                                                                                    The use of seine nets is again advantageous because
is easy to target particular species of fish. This is mainly because of the way
the net is shaped and designed. The mesh size of the net can be adjusted to
target fish of a particular species and size. This is good for the purposes of conservation
and management of the fish resources in the waters. The fishermen are able to
focus on the types of fish that are in abundance. So, for example, if they
recognize that a particular type of fish seemed to have been overfished, they
avoid them and concentrate on those that are common at the time. The use of
seine nets helps to conserve endangered fish species.

Seine net is relatively cheap Another merit of the use of seine net is that it is
that, compared to other types, seine nets are not that expensive. What this
means is that, the fisherfolks who operate on a small-scale are able to afford
it, especially, if they do not have enough money to buy those that are more
expensive.<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEutG3tUomX3wJ1B2IUdmbpS107Apl97PpnFO4TRV4RxIIJ2JzpLY8l8fXD6_hlMXfiMoIcs33ln9EWl-47aLCzqZtAIyye7ymXV2rbdR-yksno1APictAe2zGwv3O8AxPIlcCB4rZw6pgz76L3dY-y4h_u8HH2ERsYOQGmYVK9fCw2Oz-tHKlBOho4w/s4627/alexander-andrews-JxfKZbPDTSc-unsplash.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="4627" data-original-width="3085" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEutG3tUomX3wJ1B2IUdmbpS107Apl97PpnFO4TRV4RxIIJ2JzpLY8l8fXD6_hlMXfiMoIcs33ln9EWl-47aLCzqZtAIyye7ymXV2rbdR-yksno1APictAe2zGwv3O8AxPIlcCB4rZw6pgz76L3dY-y4h_u8HH2ERsYOQGmYVK9fCw2Oz-tHKlBOho4w/s320/alexander-andrews-JxfKZbPDTSc-unsplash.jpg" width="213" /></a></div> Seine net is versatile                                                                              
                                    There is a level flexibility
in the use of seine nets that adds more advantages to their use. For example,
it can be used in a variety of locations. It can be used in shallow waters, as
well as, in deep waters. Therefore, with seine nets, fishing can be done in different
locations.

It is environmentally friendly                                                                                                   The use of seine
nets is environmentally friendly. This is mainly because no chemicals or
explosives are employed in their operation. The advantage here is that, no
chemical or explosive pollutants are introduced into the environment or
especially into the water that may damage the fish habitat.

It reduces bycatch  Another
advantage of using seine net is that there is reduced bycatch. A bycatch refers
to the situation where fishermen catch fish that they did not intend to catch
and there have to return them into the water. This is because, seine netting is
able to target specific species.

May be difficult to operate operate                                                                                            Seine nets may be difficult to use. A lot of skills
and experience is required for one to be able to operate them. If the fisherman
using the seine nets is not very experienced, he may not be able to effectively
use it. This can lower drastically, the amount of catch at the end of the day.

May cause destruction to the environment                                                     
                           The use of seine nets has
another disadvantage, that is, they can be damaging to the environment in which
they are used. For one thing, seine nets get caught up in coral reefs. When
this happens, they destroy the coral reefs. They are also capable to destroying
habitats under the water. They endanger the lives of sea turtles by entangling
them in their mesh. This sometimes results in the death of the turtles. Dolphins,
and other marine lives are not spared the plight experienced by the sea turtle.
Again, seine nets can spread alien invasive species in water bodies, and this
has negative consequences on the underwater ecosystems.

Seine nets can catch non-target species                                                                                   One of the disadvantages of using
seine net is that it can catch some other species that were not originally
target before the fishing expedition. The consequence of this occurrence is
that, some fish species may be overfished as a result of its wide spread use
and that cause those species to be depleted from their habitat. which can lead
to overfishing and depletion of certain fish stocks.

It can be difficult to use in deep watersAnother disadvantage of using seine
nets is that, they are typically cumbersome to use in deep waters. The net is
designed in such a way that, they can only be lowered up to a certain of the
water. This is a limitation to how deep the fisherman can reach in his quest to
catch fish. Because of this limitation, the seine net not able to get to ranges
of fish habitat that are beyond the reach of the net.

Can cause damage to the sea floor                                                                                   Again, seine net can cause damage to
the sea floor, especially by those who use it on commercial basis. This happens
when the net is dragged along. There is a considerable damage to marine life in
the water body. Seine nets can especially destroy coral reefs, causing a lot of
damage to the existing food chain. If the food chain is disturbed, it can result
in the death of some marine species. Again, if the food chain is disturbed, it
will affect the health of the ocean.

Seine nets can be difficult to monitor It is difficult to monitor the use of
seine nets because of the size and complexity. There are difficulties in
ensuring that they are sustainably used. This difficulty in monitoring may lead
to overfishing. Overfishing would also lead to the depletion of some fish
stocks.

Conclusion                                                                                                                                 The seine net has become an
increasingly popular tool in the fisheries industry, due to its efficiency and
affordability. Despite its many advantages, it is important to recognize the
potential disadvantages that come with its use. Proper monitoring and
regulation of seine nets is essential in order to ensure that they are being
used sustainably and responsibly. By understanding the advantages and
disadvantages of seine nets, we can better ensure that they are used in a way
that benefits both the fishermen and the environment.

DISADVANTAGES OF USING CAST NETS IN FISHING?<o:p></o:p>

Introduction<o:p></o:p>

A cast net is a type of fishing net that is circular and
hand-thrown into the water to capture fish. It is made of a heavy mesh material
and has weights along the edge so that it spreads out in a circle as it is
thrown. The net is designed to sink quickly, trapping fish that are swimming
near the surface. Fishing with a cast net is an ancient fishing technique used
by anglers for centuries. It is a highly effective and efficient way to catch
fish, but it is not without its drawbacks. In this article, we will explore the
advantages and disadvantages of using cast nets for fishing. We will look at
the practical aspects of using a cast net, as well as the potential risks
associated with it. By the end of this article, you should be able to decide if
cast nets are a suitable fishing method for you.<o:p></o:p>

THE ADVANTAGES OF USING A CAST NET<o:p></o:p>

A cast net is
a really perfect fishing method for folks that don't have a variety of time to
spend money on fishing. It's far extraordinarily fast and smooth to apply
compared to other fishing techniques, making it a top-notch choice for
individuals who need to quick seize a few fish. Not handiest does it take less
time to deploy than other techniques, but it also yields a higher achievement
rate, that means that you are more likely to trap something with a forged net
than some other method. It is a fantastic preference for absolutely everyone
who wants to spend less time fishing and greater time playing the seize.<o:p></o:p>

One of the
angler's useful tools is the cast net. This is because it is versatile. It can
be used in different kinds of waters, the shallow water, the deep one and any
types in between. It is also useful because it allows the fisherman to target a
variety of fish species, catching any type of fish swimming where the net is
cast. By its very design, one can easily throw it in the water and retrieve it
immediately. A cast net is not as expensive as other fishing gears, this means
it is easy to acquire.<o:p></o:p><div class="separator" style="clear: both; font-family: Calibri, sans-serif; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPSMhMX5GYg0mA4i07kfxG1QqQHl6rY2OVMBg2QgRxERL7cTwhupzlOlA6bqyVSZXscff4vmmUheDPpxO5ULH6nB_7XIjNapMhIFtjMZkzPZX16q_R-lqCWbCny_KcNSlWPBJfTa2FuAwi-NWa_dRM5fnF0UVwb9BdBJSySNK9Nz-ZACiB89pWDidEAw/s290/The%20advantages%20of%20using%20cast%20nets.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="210" data-original-width="290" height="210" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPSMhMX5GYg0mA4i07kfxG1QqQHl6rY2OVMBg2QgRxERL7cTwhupzlOlA6bqyVSZXscff4vmmUheDPpxO5ULH6nB_7XIjNapMhIFtjMZkzPZX16q_R-lqCWbCny_KcNSlWPBJfTa2FuAwi-NWa_dRM5fnF0UVwb9BdBJSySNK9Nz-ZACiB89pWDidEAw/s1600/The%20advantages%20of%20using%20cast%20nets.gif" width="290" /></a></div> <div style="text-align: left;">It is cost effective</div>

Another
advantage of the use of a cast net is that it is very cheap in terms of price.
It is therefore, a cost-effective way to provide the fish protein needs of the
family. A cast net can be used at different places like in rivers, lakes,
lagoons and in the coastal areas. Additionally, a cast net is very easy to use.
One does not require that much equipment to launch. This makes it the poor man's
choice of fishing gear. It also the first choice for those who are just
starting out to fish.<o:p></o:p>

Another
advantage of a cast net is that it is an exceedingly powerful fishing device
due to it high rate of fish capture. A cast net can be thrown over a wide area.
This allows the net to catch a variety of fish by just one swoop. Also, a cast
net has a simple layout, therefore, it is easy to apply even if the person is
an inexperience fisher man. Anyone who is looking out to maximize their fish
catch has a cast net to choose since it is the perfect tool for the fisher man.<o:p></o:p>

An additional
advantage of a cast net is that it is an incredible choice for people who are
environmentally conscious. The cast net does now not require chemicals before
fish can be caught. Once more, it does not need any motorized machines to
function. This makes it one of the most sustainable strategies of fishing.
There may be less noise pollution when using a cast net, in contrast to the
usage of outboard motors mounted on canoes which produces carbon monoxide that
is harmful to the surroundings and to human beings.<o:p></o:p>

THE DISADVANTAGES OF USING CAST NET<o:p></o:p>

Cast nets are
not portable and can be difficult to transport<o:p></o:p>

Using a cast
net may be a terrific manner to trap fish, however they may be as a substitute
unwieldy and tough to transport. Cast nets are huge and cumbersome, and
commonly require a few human beings to assist convey it. Moreover, they may be
very heavy, making them hard to move from one spot to any other. If you're
seeking out a portable fishing solution, forged nets may not be the fine
desire. Fortunately, there are many other alternatives that are easier to move
around, such as spinning rods and reels, jigs, and hand-lines. These strategies
may be a great deal extra portable and convenient, while still permitting you
to trap lots of fish. <o:p></o:p>

Cast nets can
be dangerous, as they involve throwing a weighted net into the water<o:p></o:p>

The use of a cast net includes
throwing a weighted net into the water for one to catch fish. Whilst this is a
traditional and powerful technique of fishing, it may be risky if precautions
are not taken. It is very critical for the angler to ensure that there are no
humans around before the net is cast. This is because the net can be heavy and
if it hits a person, it can cause injuries. The angler must also wary of any
obstacles in the area since the net may be entangled around the obstacle. Also,
if improperly used, the cat net can wrap around the fingers of the user or his
body. <o:p></o:p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgxTNpGwq099caXACmyY8ae9mu75t7hzehJrgmm85apNSnnmbFjF8buexZJLpnxA5uWMsSt9P6JDJ7Aoav2cPuktmBhX9SWobMNrhOIJveXZtrzsS4eeZIx_PMqrYoXqKQTCMFot7WR58vmrbA4mfEsV5uOm2h9EfJDfr-DcSVeoj3WGbRUgDVh-DgL8w/s290/disadvantages.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="210" data-original-width="290" height="210" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgxTNpGwq099caXACmyY8ae9mu75t7hzehJrgmm85apNSnnmbFjF8buexZJLpnxA5uWMsSt9P6JDJ7Aoav2cPuktmBhX9SWobMNrhOIJveXZtrzsS4eeZIx_PMqrYoXqKQTCMFot7WR58vmrbA4mfEsV5uOm2h9EfJDfr-DcSVeoj3WGbRUgDVh-DgL8w/s1600/disadvantages.gif" width="290" /></a></div> <div style="text-align: left;">Cast nets can
be disruptive to the environment</div>

Cast nets can
be very disruptive to the surroundings. This is because they could disturb the
delicate balance of aquatic environment. Cast nets can cause extensive damage
to aquatic habitats. They may also stir up sediment in the water and disrupt
flora. Furthermore, cats nets can injure animals which might be stuck in them,
this may lead to the decrease in the population of some species in selected
regions. Additionally, the use of cast nets can reduce the amount of oxygen in
the water. This can create unfavorable aquatic environment for fish life.<o:p></o:p>

Cast nets may
not be allowed in certain areas, due to conservation laws. <o:p></o:p>

Cast nets may
be very effective fishing gear in capturing fish, however, cast nets may not be
allowed in certain jurisdiction because of conservation laws. One of the major
reasons for establishing conservation laws is to protect the environment,
especially, in the fisheries sector, to protect marine life. The use of cast
nets may be prohibited to prevent the over fishing of some fish that may be
endangered. <o:p></o:p>

Cast net can
be difficult to use in areas with strong currents or heavy vegetation<o:p></o:p>

The use of
cast nets can be hectic where there are strong currents or heavy vegetation.
This is because, the wind can distort the direction intended by the angler and
shift it elsewhere. This may prevent the angler from catching the type of fish
desired. Also, the net can be caught in vegetation and makes maneuvering
cumbersome for the angler. <o:p></o:p>

In
conclusion, one can say that the use of cast net to catch fish has a lot of
advantages. It may be used for a number of purposes, is quite simple to master,
and can be used to catch different kinds of fish. The use of cast net may be
subject to conservation laws of the state. It is also important to recognize
how their use affects the environment. Cast net fishing may be an effective,
efficient, and sustainable method of catching fish when done properly.<o:p></o:p>

CLASSIFICATION AND DESCRIPTION OF SOME FACILITIES THAT ARE COMMON AT FISH
LANDING SITES</div><o:p></o:p>Introduction

The
facilities at fish landing sites are essential to the success of any fishing
enterprise. Whether it's a small, family-owned business or a large commercial operation,
having the right tools and infrastructure in place can make all the difference.
In this article, we'll take a look at the different types of facilities
available, how they can benefit fishermen, and what should be taken into
consideration when selecting a fish landing site. We'll also discuss the
importance of good maintenance and proper management of these facilities to
ensure they continue to serve the fishing community for years to come.<o:p></o:p>

FACILITIES
AT FISH LANDING SITES AND HOW THEY ARE UTILIZED <o:p></o:p>

Winch<o:p></o:p>

A winch is a
machine that is used to wind up, or spool a cable or rope. A winch is either
operated by electricity or by hydraulics. They can be operated by the use of
manpower by remote control. A winch is used to launch or to retrieve fishing gear.
Some of the fishing gear a winch is used to deploy are trawl nets, longlines,
pots and buoys. A winch can be used to pull heavy buoys, anchors, etc. It can
be used to pull nets on the surface of the water, to deploy the gear at the
desired depth, and to retrieve the gear from the water. <o:p></o:p>

Cold store <o:p></o:p>

A cold store
is one of the major facilities that is central to operations of the fishing
industry. It is so because it helps preserving of fish products. It is a
warehouse of a sort which is temperature-controlled. There, fish products are processed
and distributed through the market chain in the fisheries industry. It is in a
cold store that we store fresh and frozen seafood, before it is sold to a
prospective buyer. Fish products can also be processed, packaged and
distributed to the market. The cold store is designed to maintain a constant
temperature and humidity level. The temperature is usually from 0 degrees
Celsius, up to 5 degrees Celsius. This temperature level is intended to keep
the fish product fresh all the time and prevent it from going bad. Some cold
stores are equipped with blast freezers, ice-making machines and vacuum-packing.
The equipment is able to further prolong the shelf life of the fish products. <o:p></o:p>

Ice plant <o:p></o:p>

Another
facility which is crucial to the fisheries industry is an ice plant. This is
because it ensures that fish products are safely transported to the consumer in
a top-quality form. No spoilage entertained.  An ice plant is used to produce ice and store
the same for use by the fishing industry. It has an industrial refrigeration
system, large-scale freezers, and a space to store it. The ice plant is needed
in the preservation of fish products when being transported to the market or to
the processing plant. The ice helps to preserve the flavor and texture of the fish
product. <o:p></o:p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjN_IFYuzbeXYACW8fz136Lvq6K2y9AHe4cjZqkR9EQOh_rF0n7oXleux1Rquxm1uNcOch2XOKQPGFq6jFep5FY3JJ8KVMdFf5fFMDFpDUvzuIMkUC4BolkhV_28n6PVNmZluKEHE-OY2dhAYmETkS3JJpydP5wc6XDRH1qkDA2sHbq8gjGJkkH9mqnEg/s640/gas%20station.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="427" data-original-width="640" height="268" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjN_IFYuzbeXYACW8fz136Lvq6K2y9AHe4cjZqkR9EQOh_rF0n7oXleux1Rquxm1uNcOch2XOKQPGFq6jFep5FY3JJ8KVMdFf5fFMDFpDUvzuIMkUC4BolkhV_28n6PVNmZluKEHE-OY2dhAYmETkS3JJpydP5wc6XDRH1qkDA2sHbq8gjGJkkH9mqnEg/w400-h268/gas%20station.jpg" width="400" /></a></div><div style="text-align: center;">(Gas station)</div>

Fuel station
<o:p></o:p>

With the
invention of engine operated machines, and the incorporation of the same into
machinery used in the fishing industry, fuel has become an essential commodity
in fueling almost all machines. Fuel stations have therefore become one of the
most important facilities for providing fuel for fishing vessels. Some of the fuel
types provided at fuel stations include diesel, gasoline, and others. This is dependent
on the particular needs of the vessels. Fuel for the fishing industry is used
for several purposes. For example, fuel is needed to power diesel engines in fishing
vessels. Fuel is needed for cooking and heating on board fishing vessels. At fuel
stations where vessels are served, other services like the washing of vessels
and general maintenance. Additionally, they refuel vessels.<o:p></o:p>

Slipway<o:p></o:p>

One of the
features that strikes a person in a visit to a shoreline or riverbank when A
slipway is a structure along the shoreline or a riverbank is a ramp that slopes
into the sea or river. This structure enables boats to be launched into the
water or retrieved from the water. This structure is called a slipway. Slipways
are also useful during the repair and maintenance on vessels, because the
repair is carried out there. <o:p></o:p>

Dry dock<o:p></o:p>

Fishing
vessels are essential aspect of the work of fishermen and the fishery industry.
There are times, however, when the vessel is not in use, for example, during
closed seasons or just a place to keep the boat. That place where the boat is
kept during this period is called a drydock. A drydock is located on the
shores. It is a holding place for ships when they are under repairs or being
serviced. On one side is a wall, which is intended to block off the sea and on
the other is a sloping ramp. The purpose of the slopping ramp is to allow ships
to enter and to exit. A drydock is used, to enclose ships for security reasons.
Ships and boats are kept here during the clos season when vessels normally do
not launch to the sea or into the river or lake. <o:p></o:p>

Jetty <o:p></o:p>

A jetty is used
for various purposes in the fishing industry. It provides access to deeper
water areas. It provides shelter for boats to dock and also easier access to
fishing grounds. Since it is a structure that is built and extended into the
water from the shoreline, they serve also as a barrier against strong currents
and waves. This way, they offer protection to boats and prevents damage. A
jetty is also a structure for fish to gather thereby creating a popular place
to fish. It is a place boats can drop their nets and for anglers to stand and
launch their fishing lines. It is a place for boats to moor. A jetty is made of
concrete, wood, stone, or metal and could be built on the shores of a lake,
river or ocean. <o:p></o:p>

Breakwater<o:p></o:p>

The purpose
of a breakwater is to reduce the force of waves, strong currents, and flooding.
While it does this, it protects the harbours and the fleet of ships the forces
of the waves and storms. It prevents dirt and other pollutants from getting
into the harbour and this, on its own, creates a healthy environment for fish
and other aquatic life forms. A breakwater creates a calmer water and makes
maneuvering easy for vessels. Breakwaters can be either artificial or natural,
and are usually built from large stones, boulders, or concrete. A breakwater is
usually built along the coast line and harbours.<o:p></o:p>

Conclusion<o:p></o:p>

The
facilities at fish landing sites are essential to ensure the safe and efficient
unloading of fish and other marine products. They provide a crucial platform
for local communities to access the seafood they need, while also providing a
vital source of employment to those working in the fishing industry. With
increased investment in these facilities, it is possible to improve the
sustainability of the fishing industry and ensure its continued growth for
future generations. It is clear that fish landing sites provide a great benefit
to our communities, and it is important that we continue to invest in them.<o:p></o:p>Also Read:<a href="https://www.virtualkollage.com/2023/05/how-to-classify-and-describe-common-fishing-gears-like-cast-nets-trawl-nets-dredge-nets-seine-nets-scoop-nets-hooking-devices-stationary-nets-tangle-nets-and-fishing-traps.html" target="_blank">How to classify and describe the common fishing gears used in the fishery industry</a> <a href="https://www.virtualkollage.com/2023/05/describe-some-harmful-fishing-practices-and-how-they-affect-fishery-habitat.html" target="_blank">Describe some harmful fishing practices and how they affect fishery habitats</a> <a href="https://www.virtualkollage.com/2023/05/what-are-the-negative-effects-of-aquatic-alien-invasive-species-like-water-hyacinth-water-lettuce-papyrus-reed-hornwort-on-fishery-harbitats-fishery-organisms-and-fisher-men-and-women-in-ghana-nigeria-sierra-lieone-liberia-and-the-united-states-of-america.html" target="_blank">What are the effects of aquatic invasive alien species on fishery habitats, fishery organisms and fishermen/women.</a> <a href="http://www.virtualkollage.com" target="_blank"><<Back to Home Page</a> <a href="https://www.virtualkollage.com/p/list-of-subjects.html?m=1" target="_blank">Go to the list of other subjects>></a> <a href="https://www.virtualkollage.com/p/fisheries-fisheries-syllabus-has-been.html" target="_blank">Go to other topics on fisheries>></a>

AND DESCRIBE THE COMMON FISHING GEARS USED IN THE FISHERY INDUSTRY<o:p></o:p>

Introduction<o:p></o:p>

From ancient days up to this present day, fishing has
constantly been accomplished by way of using gear. Other than using bare
fingers to capture fish, most fishermen have used gear and those are usually
referred to as fishing gears. As the science of fishing developed, so have the
equipment employed become increasingly more sophisticated. The form of fishing
tools hired by means of a fisherman is generally determined by the type of
fishing one is engaged in, whether or not one is actively or passively fishing
determines what equipment to employ. Active fishing refers to the situation in
which the fisherman does not wait for the fish to come to the bait, he actively
seeks for and captures them. Passive fishing is the direct opposite of active
fishing. It does not involve actively chasing the fish. The fisherman just waits
the fish to approach a fishing line or a trap already set. In this text, we
will provide the diverse fishing equipment on the market these days, and
additionally describe them for easy identification.<o:p></o:p>

TYPES OF
FISHING GEAR USED IN ACTIVE FISHING <o:p></o:p>

Cast net <o:p></o:p>

Cast nets
are a few of the equipment for active fishing. 
This net is often used by one person, typically in shallow waters. To
cast the net successfully, the fisherman needs to release the bait while
standing in the water. He holds the net in his dominant hand. He swings and
releases the net directly to a desired spot. Cast nets are a common piece of
fishing gadget, but gifted handlers of the net are able to successfully use it.<o:p></o:p>

Trawl net<o:p></o:p>

Another type
of fishing gear used for fishing is called trawl. The trawl uses a large net
which is dragged through the water. As the trawl is dragged, the fish collects
into the net. The trawl is used to catch different types of fish species. Some
of the species include herring, mackerel, tuna, shrimp, squid, shrimp, and
others. A trawl consists of two large bags which are connected by a frame. In
the front is a funnel-shaped opening. It is fixed behind a boat and as the boat
moves, the trawl is dragged along the ocean floor and collects the different
types of fish from along its path in the water. The trawl is equipped with a “codend”.
This “codend” is a device that collects the fish but prevents them from
escaping. <o:p></o:p>

Dredge net<o:p></o:p>

A dredge is
a type of fishing gear used by commercial fishing vessels. They are typically
employed in the harvesting of seafood from the ocean floor. Some of the seafood
captured with a dredge include scallops, shrimp, oysters, clams, and crabs. The
dredge is a large, metal frame with heavy chain mesh as an attachment. The
dredge is dragged along the seafloor and the mesh bags collect the organisms
living on the seafloor. The dredge is typically towed behind a boat and the
organisms are collected and brought up to the surface. This gear is commonly
used for harvesting shrimp, oysters, clams, and crabs. Dredging is an effective
way to gather large amounts of fish in a short amount of time.<o:p></o:p>

Seine net<o:p></o:p>

Another
fishing gear used in the industry is called seine net. It is a type of fishing
net that is vertically hanged in the water. In order to keep it floating, weights
are attached to the bottom edges. It is the type of fishing gear mostly used in
shallow waters to capture fish. Seine nets can be used in rivers, oceans and at
the shorelines of lakes. This is how the seine net is employed; Two groups of
people, holding either side of the net, pull the net in a circular motion. The
aim is to encircle the fish. Once the net is encircled, it is drawn to the shore.
It is here that the catch is collected. The net is then drawn to the shore,
where the catch can be collected. Some types of fish the seine net can catch include
herring, smelts, mackerel, and salmon. One very good thing about the use of
seine net is that, it can be used to harvest very large quantities of fish at a
go.<o:p></o:p>

Scoop net<o:p></o:p>

Scoop nets
are a type of fishing gear typically used for catching bait fish. They are
typically made from a wire mesh or plastic mesh and have a handle with a long
hoop at one end. The hoop is used to scoop up the fish from the water. The mesh
of the net ensures that the fish can't escape while they are being scooped up.
The size of the net determines what kind of fish it can catch, with larger ones
being able to catch bigger fish. Scoop nets are usually used in shallow water,
and they are often used by recreational anglers.<o:p></o:p>

TYPES OF
FISHING GEAR USED IN PASSIVE FISHING  <o:p></o:p>

Hooking
devices<o:p></o:p>

Hooking
devices are one of the most common and effective forms of fishing gear, used by
passive fisher folks. They consist of a line attached to a hook, which is used
to catch fish. Hooks come in a variety of sizes and styles, depending on the
type of fish being targeted. They are typically used with bait, lures, and jigs
to attract and catch fish. Hooks come in both barbed and barbless varieties,
with barbed hooks more commonly used for larger fish and barbless hooks ideal
for smaller species. Hooks can also be weighted to help with casting and to
keep them in the water for longer. Hooking devices are an essential piece of
fishing gear for any angler.<o:p></o:p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjyN7DVTwVHm2GDMUgMyYFZRvTwG20M9cB7qpLXIT9AxjfIt_b6xPRU-U2FLMw_g1YwAhncSPZ93mXk3ggNzvOPb_JJM9L1EY5lcfmSk9QIII1cWX21ImsgWw-FnzSNKMbHlpUCK7eslloY94riVMzE1NslOFBC5DxlV3TtExxaTi3zl1YhIvxyQDReeA/s640/hooks.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="487" data-original-width="640" height="305" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjyN7DVTwVHm2GDMUgMyYFZRvTwG20M9cB7qpLXIT9AxjfIt_b6xPRU-U2FLMw_g1YwAhncSPZ93mXk3ggNzvOPb_JJM9L1EY5lcfmSk9QIII1cWX21ImsgWw-FnzSNKMbHlpUCK7eslloY94riVMzE1NslOFBC5DxlV3TtExxaTi3zl1YhIvxyQDReeA/w400-h305/hooks.jpg" width="400" /></a></div><div style="text-align: center;">(Hooking device)</div>

Stationary
nets<o:p></o:p>

Stationary
nets are a type of fishing gear that are set in a specific area and left in
place for a period of time. These nets are typically made from a strong,
lightweight material such as nylon and are usually weighted down with rocks or
other heavy objects. Stationary nets are used to catch a variety of fish,
including salmon, herring, cod, and mackerel. They can be set in rivers,
streams, lakes, and oceans. In some cases, stationary nets are used with other
fishing gear such as traps, seines, and trawls. Stationary nets are effective
because they are easy to set up and can be left in place for long periods of
time, allowing the fishermen to return to the same location and harvest their
catch. Stationary nets are an important part of commercial fishing.<o:p></o:p>

Tangle nets<o:p></o:p>

Tangle nets are a type of fishing gear
that involves a horizontal line with a series of vertical lines attached to it.
The vertical lines are connected to the horizontal line by means of a series of
knots which form an intricate web-like pattern. This web-like pattern is
designed to trap and hold a variety of fish, including shrimp, crabs, and even
small fish. The tangle net is typically constructed from a strong, durable
material such as nylon or polyester and is often weighted down near the bottom
of the net to help keep it in place. The net is typically placed in shallow
water and then is left to drift through the current, allowing the net to become
entangled with any fish that may be swimming nearby. Once the net is full, it
is retrieved and the fish that were caught are removed. Tangle nets are an
effective way to catch baitfish, shrimp, and other small aquatic organisms, and
are commonly used by commercial fishermen and recreational anglers.<o:p></o:p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgnymIiA-R3TqtOekPhBmXMCsghgh8UQ13OVxIgZXN6tMI6ucEt4x_CqBgO9zhHOhktXRzu1rhQJTVo3K-i5uXCYP8NiujeCwxh0GLB2KDORK1w6qnYztxbpEfRp8lyVGmJLEd3WdFhXQ81ZqRh-UvCQBCn95oqYNSm4v1d9DS9i4stvrYaSrR107K2fQ/s640/trap.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="428" data-original-width="640" height="268" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgnymIiA-R3TqtOekPhBmXMCsghgh8UQ13OVxIgZXN6tMI6ucEt4x_CqBgO9zhHOhktXRzu1rhQJTVo3K-i5uXCYP8NiujeCwxh0GLB2KDORK1w6qnYztxbpEfRp8lyVGmJLEd3WdFhXQ81ZqRh-UvCQBCn95oqYNSm4v1d9DS9i4stvrYaSrR107K2fQ/w400-h268/trap.jpg" width="400" /></a></div><div style="text-align: center;">(Fishing Trap) </div>

Fishing Traps<o:p></o:p>

Traps are a
type of fishing gear that is used to capture fish and other aquatic creatures.
They are designed to create a contained location that lets in fish but prevents
them from leaving. Traps are commonly set in areas where there may be a
concentration of fish, near a reef, in a shallow region, or near a shape. They
can be baited with a selection of various styles of bait, or left without a bait.
The type of bait used will depend on the type of fish being targeted. Traps
come in a variety of sizes and styles, and can be constructed from different of
materials which includes plastic, wire mesh, or timber. They are commonly set
in place with a weight or line, and left to sit for a period of time. Once the
fish gathers into the trap, it is removed from the water and the catch is
emptied.<o:p></o:p>

Conclusion<o:p></o:p>

We can
conclude that the absence of fishing gears in the fishing industry can spell
doom for the industry, they are a vital check list of the industry. The
categorization and description of fishing gear is important if we want to understand
how complex and varied fishing is. If fishing gears are properly classified and
described, fishermen can better understand the types of fishing gear available.
Such information can enable them to make informed decisions on which fishing
gears to use, subject to what type of fishing they want to engage in. It will also
ensure that they settle for the best equipment for a successful fishing trip.<o:p></o:p>

AND THEIR EFFECTS ON FISHERY HABITATS<o:p></o:p>Introduction<o:p></o:p>Fishing is a highly important part of life in Ghana, whether
it is for enjoyment or commerce. Although some fishing methods are quite
excellent, others are thought to be damaging to the environment and have
significant negative influence on the entire marine ecology. The viability of
the fishing sector cannot be guaranteed by destructive fishing techniques. In
this article, we will examine the list of harmful fishing practices and how
they affect the ecosystem. Some examples of harmful fishing practices include
bottom trawling, ghost fishing, shark finning, etc.<o:p></o:p>HARMFUL FISHING PRACTICES AND THEIR EFFECTS<o:p></o:p>Bottom
Trawling <o:p></o:p>Bottom
trawling is a fishing technique used to catch fish living near the bottom of
the ocean. It involves dragging a large net along the seafloor, catching any
fish that are in its path. The net is typically made from heavy-duty material
and is designed to withstand the pressure of the ocean depths. It is usually
attached to a boat and dragged behind it, with a weight on the bottom to help
keep it in contact with the seafloor. As the boat moves, the net is dragged
along the seafloor, catching any fish in its way. <o:p></o:p>Bottom
trawling has been described as harmful fishing practice because it not
discriminatory, it scoops a lot of sea creatures on the seafloor. This method
can also drastically slow down the growth of coral reefs and destroy fish
habitats. Sea grass, which provides shelter and food for juvenile fish may be
starved of food as a result of bottom trawling.<o:p></o:p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEhzMDfvAUSwil2D3dL0U8vUSQfmTPkzhGgMWvIBwq22AezME5fSht3028zzlsMNGvPr_kg61OUqLVSCDA-GXdcFuOfLZalieOcD36eZlpvhYCSTqtFDwnegDPAKy4QBE4D5yGaheXj2yiJxp8QGR0xwMRQ_icwmUrgWaJFeLcp9jD_0iDR1Ur7bucWL0Q" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="640" data-original-width="427" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEhzMDfvAUSwil2D3dL0U8vUSQfmTPkzhGgMWvIBwq22AezME5fSht3028zzlsMNGvPr_kg61OUqLVSCDA-GXdcFuOfLZalieOcD36eZlpvhYCSTqtFDwnegDPAKy4QBE4D5yGaheXj2yiJxp8QGR0xwMRQ_icwmUrgWaJFeLcp9jD_0iDR1Ur7bucWL0Q" width="160" /></a></div> BycatchA
fisher man goes to catch fish, he throws his net and catches a lot of fish. He
now realized that his net has caught other fishes that it was not intended to.
These unwanted fish have to be discarded. This is called bycatch. Bycatch is a
harmful fishing practice because it destroys the lives of other animals such
as, turtles, dolphins, sharks etc. <o:p></o:p> Bycatch can be devastating to marine life and
ecosystems, as it often results in the death of the animals. Bycatch can
include species that are not targeted by fishermen, such as sharks, turtles,
dolphins, and seabirds, as well as juvenile fish and other species that are not
suitable for commercial use. Bycatch can also result in the destruction of
critical fish habitat and can negatively affect the health of the entire ocean ecosystem.
<o:p></o:p>Ghost
Fishing <o:p></o:p>Ghost
fishing refers to the condition where fish and other aquatic life forms are
caught by abandoned fishing gear. There are situations where some fishing gear
is lost and left in the water body. This fishing gears, like long lines, remain
in the water and continues to entangle and kill marine life. These catches are
not intended but occurs all the same. Ghost fishing can occur when lost items
such as longlines, nets, and other fishing gear are left behind in the ocean
and continue to fish. This can lead to the entanglement of marine mammals,
seabirds, and other species, resulting in death or injury. Ghost fishing also
leads to the destruction of habitats and the displacement of fish and other
species. Ghost fishing has a lot of negative effects on the ecosystem.
Non-targeted species are accidentally captured, for example, and this may lead
to the decline in population of some species. There is also the problem of
marine debris.<o:p></o:p>Shark
Finning <o:p></o:p>Shark
fin soup is one of the delicacies on the menu of many restaurants. However, the
process of obtaining the shark fin is harmful. When a shark is caught, the fin
is removed and the rest of the body is discarded. This type of fishing practice
is a very harmful one. Shark finning a major cause of overfishing. It threatens
the existence of other aquatic organisms. In the long term, shark finning can
threaten their population and damage the marine ecosystem. <o:p></o:p>Use
of Cyanide <o:p></o:p>Some
people use cyanide to fish, though it is an illegal and dangerous practice. They
make a few drops into the water and once the fish come into contact with it,
they are stunned and reduces their agility. This makes them easier to catch. In
Ghana, it is illegal to use cyanide to fish. One serious problem associated
with the use of cyanide is that it poses a threat to the ecosystem. The coral
reefs are then unable to provide food and shelter as should be the case.
Eventually, the population of some aquatic organisms may be reduced or may even
become extinct. Using cyanide can lead to the ingestion of the same since the
products get contaminated.<o:p></o:p>Use
of Explosives <o:p></o:p>Another
harmful fishing practice is the use of explosives. Explosives are used to
generate shock waves in the water and this stuns the fish and immobilizes them
until they are scooped. Explosives are used by both commercial and recreational
fishermen. This method of fishing can destroy coral reefs and other aquatic habitats.
Apart from destruction to coral reefs, it can lead to the death of fish and
other marine organisms. Explosives are made from chemicals, so using them to
fish can lead to the release toxic chemicals into the water. This poses danger
to ecosystems. It can also contaminate water and make them unwholesome to drink.
The people who use the explosives expose themselves to the hazardous chemicals
in the explosives. <o:p></o:p>Aquaculture
Impacts<o:p></o:p>Aquaculture
refers to that type of farming where aquatic organisms are reared. Some of the
organisms reared include crustaceans, mollusks, and aquatic plants. Aquaculture
is used to supplement traditional fishing activities and to help preserve
species that are becoming increasingly scarce due to overfishing. Aquaculture can
also provide a reliable, sustainable source of food and income for coastal
communities. Examples of aquaculture techniques include rearing fish in ponds,
cages, or tanks; cultivating seaweed or shellfish on ropes or trays; and
raising shrimp in man-made ponds. In addition, aquaculture can help to restore
damaged fisheries and habitats, as well as reduce the pressure on wild fish
stocks. Aquaculture has a lot of disadvantages. It destroys the natural habitat
of wild fish. The wild fish population can also contract diseases and parasites.
Through aquaculture, aquatic alien invasive species may be introduced into the
environment. Pollutants like fertilizers and antibiotics could be introduced into
the water, which can damage the quality of the water. Interference in the
migratory patterns of wild fish may also be caused by aquaculture.<o:p></o:p>Conclusion<o:p></o:p>

To conclude, harmful fishing practices have negative consequences
marine ecosystems. If the practice is not properly controlled, it can destroy
habitat of marine life forms. Fishing will become unsustainable. <o:p></o:p>Also Read: <a href="https://www.virtualkollage.com/2023/05/the-characteristics-of-fish-habitats-like-freshwater-brackish-water-marine-water-rivers-lagoons-ponds-streams-estuary-pelagic-demersal.html" target="_blank">The characteristics of fish habitats</a> <a href="https://www.virtualkollage.com/2023/04/how-to-identify-and-describe-the-common-fisheries-organisms-like-tuna-tilapia-crab.html" target="_blank">How to identify and describe common fisheries organisms</a> <a href="http://www.virtualkollage.com" target="_blank"><<Back to Home Page</a> <a href="https://www.virtualkollage.com/p/fisheries-fisheries-syllabus-has-been.html" target="_blank">Go to other topics in fisheries>></a> <a href="https://www.virtualkollage.com/p/list-of-subjects.html?m=1" target="_blank">Go to the list of subjects>></a>

FISHERY HABITATS TO ENHANCE FISH PRODUCTION<o:p></o:p>

Introduction<o:p></o:p>

One of the great threats to the health of aquatic ecosystems
and fisheries habitats is what is referred to as alien invasive species or AIS.
It is one of the greatest threats because the invasive alien species have the
capacity to outcompete the species native to the habitats and alter the
environment. Some of these invasive alien species include water hyacinth, water
lettuce, and hornwort. They are also able to spread diseases and parasites.
They can reduce the availability of food in the ecosystem. In this article, we
will discuss the various methods that can be employed to prevent and control
these alien invasive species so that countries can take control of their
fisheries habitat to make maximum gain from them. <o:p></o:p>

HOW TO PREVENT AND CONTROL ALIEN INVASIVE SPECIES

Awareness creation<o:p></o:p>

One of the most effective methods that can be used in the
prevention and control of alien invasive species is to create awareness. It is
probable that many people do not know about the negative effects of these alien
invasive species. People need to be aware, be able to identify the plants, its
mode of propagation etc., This awareness creation may take the form of public
campaigns using flyers, adverts on Television and radio, banners at vantage
points along water bodies. One can also use Social Media handles to drive this
awareness creation. Public discussions on the issue on radio and TV is another
option. These campaigns will educate people on the importance of preventing and
controlling the invasive alien species.<o:p></o:p>

Screening at entry points <o:p></o:p>

Another method to use in preventing and controlling the
alien invasive species is by screening people who enter the country through the
entry points. In many parts of the world, people use different routes to enter
another country. People may use land borders, air and Sea ports. Others may
even use unapproved routes as their point of entry. In all these cases,
measures must be put in place to ensure that whatever plant species or seeds
they are bringing in is properly scrutinized. This will ensure that if there
are any invasive alien species coming in, they can be seized and destroyed. <o:p></o:p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTw78Ya0BPkKAdUPyy1Gfx32TpQKC7QmQxNFSvncZB3kDzfb39ps8QFog2BPh_RukXYxrExnmZIW70QQcTjQQJnKzay19nirb5XM9pBqjJAZJWJNOUZvpIdDlk1_JYFUmcIP_Nc68ARJWzLAlVb8GUiysQ0TQS4JY1SPDb2026b2CTHtbC5pFVPuL6JQ/s640/water-hyacinth_2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="427" data-original-width="640" height="268" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTw78Ya0BPkKAdUPyy1Gfx32TpQKC7QmQxNFSvncZB3kDzfb39ps8QFog2BPh_RukXYxrExnmZIW70QQcTjQQJnKzay19nirb5XM9pBqjJAZJWJNOUZvpIdDlk1_JYFUmcIP_Nc68ARJWzLAlVb8GUiysQ0TQS4JY1SPDb2026b2CTHtbC5pFVPuL6JQ/w400-h268/water-hyacinth_2.jpg" width="400" /></a></div><div style="text-align: center;">(Water hyacinth)</div><div style="text-align: left;"> </div><div style="text-align: left;">Enforcement of plant protection laws</div>

Countries can also prevent and control alien invasive
species by their enforcement of plant protection laws.  The state must as a matter of agency pass
legislation, if they do not already exist, and make sure that these
legislations are enforced to the letter. Anyone who flouts these regulations
must be made to face the full rigours of the law. In Ghana, there is the Plant
Protection & Regulation Services Department of the Ministry of Agriculture
in Ghana. In Nigeria they have the Nigerian Agricultural Quarantine Service. In
Liberia, there is the Liberia Plant Protection Regulatory Services Bureau under
the Mistry of Agriculture. It is the candid opinion of this writer that if the
laws are enforced, it would lead to the prevention and control of these
invasive alien species.<o:p></o:p>

Physical control<o:p></o:p>

Though this method is labour intensive, alien invasive plant
species can be physically controlled. For example, gangs of young men can be
employed and transported to the Volta Lake, for example, where they would
manually cut water hyacinth into canoes and brought back ashore. Small boats
fitted with cutter can also be taken onto the water body to mechanically cut
these invasive plant species and brought ashore for onward destruction. This
can cut down on the rate of propagation.<o:p></o:p>

Biological control<o:p></o:p>

One can also prevent and control alien invasive species
biologically. Natural enemies of these species can be introduced into the
ecosystem to overpower them. For example, the natural enemies of water hyacinth,
like weevils, and beetles can be introduced into the space. Since the beetles
or weevils feed on these invasive species, it can suppress its growth. Also,
when sediments are removed from the bottom of the water, it can prevent or slow
down the rate of growth and spread. <o:p></o:p>

Incentive and reward mechanisms<o:p></o:p>

Also, we can use reward and incentives to prevent and
control alien invasive species. We cam institute a reward mechanism for
reporting sighting of alien invasive species in or on water bodies. For
instance, if an individual or organization reports sighting an alien invasive
species, that individual is rewarded in cash or in kind. If the rate of participation
is high and sightings are promptly reported, it can go a long way to control
water species like water hyacinth and water lettuce for example. <o:p></o:p>

Research and development<o:p></o:p>

Further research into the phenomenon of alien invasive
species is another method that can be used to control and prevent alien
invasive species. Where research and development is already established to
research into alien invasive species, governments can also support with funding
to ensure there is enough available to research into the issue and come up with
workable solutions to solve the problem.<o:p></o:p>

Other methods that can be used include, public-private
partnerships, early warning and rapid response systems, promotion of best
practices, development of risk management mechanisms.<o:p></o:p>

Conclusion<o:p></o:p>

The complexity of the control and prevention of alien
invasive species is not something to be glossed over. Since this is a matter
national emergency, it is important for governments, businesses, and
individuals to come together and work to identify the sources of invasions and
to assess its effects the environment and subsequently on the economy. If the
above discussed methods are implemented, we can the impacts of alien invasive
species can be managed.<o:p></o:p>Also Read:<a href="https://www.virtualkollage.com/2023/05/what-are-the-characteristics-of-alien-invasive-species-like-water-hyacinth-water-lettuce-papyrus-reed-hornwort-in-fisheri-harbitats-in-ghana-and-nigeria.html" target="_blank">What are the characteristics of alien invasive species?</a> <a href="http://www.virtualkollage.com" target="_blank"><<Back to Home Page</a> <a href="https://www.virtualkollage.com/p/list-of-subjects.html?m=1" target="_blank">Go to the list of other subjects</a>>> <a href="https://www.virtualkollage.com/p/fisheries-fisheries-syllabus-has-been.html" target="_blank">Go to other topics in fisheries>></a>

HYACINTH, WATER LETTUCE, PAPYRUS REED HORNWORT, ETC., IN FISHERY HABITATS<o:p></o:p>

Introduction<o:p></o:p>

Invasive alien species have become a major problem in many parts
of the world. These non-native species often spread quickly and cause
significant ecological, economic, and social damage. In this article, we will
identify and describe some alien invasive species such as water hyacinth,
Papyrus reed, water lettuce, and more. We will explore their morphology, mode
of propagation, growth and development.<o:p></o:p>

IDENTIFICATION AND DESCRIPTION<o:p></o:p>

Water hyacinth (Eichorniacrassipes) <o:p></o:p>

Water
hyacinth is one of the common alien invasive species in the world. The leaves
of the plant are bright green and the flower is purple in colour.  Its leaf is fan-shaped. It also has thick and
spongy stalks and the roots are thick and fibrous. The leaves are oval to
heart-shaped and can reach up to 20 cm in length.<o:p></o:p>

The
water hyacinth plant is able to quickly adapt to its environment. It can also
by a variety of methods. One common way by which it spread is by the use of
water currents. It can also be spread by the wind. Humans also constitute a
major mode of spread when they when they transport the plant from one location
to another. Typically, the seeds of the water hyacinth plant can thrive for
many years so it can reproduce rapidly through the seeds. <o:p></o:p>

One
important characteristic about the water hyacinth is that, it can grow and
develop rapidly. Within a space of weeks, the plant can form dense mats to
cover an entire water body. When this happens, the amount of light available
for other species is reduced. This subsequently reduces the amount of oxygen
available for other species. This can lead to a decrease in biodiversity and a
decrease in the number of fish in the area.<o:p></o:p><div class="separator" style="clear: both; font-family: Calibri, sans-serif; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQ3jpFPMsyXaWZ-b8dSE6oepH_tfGkX7-ZJwsfep79b0-fMcnfPfKnORbXevDObG06XLpSAcTrWO6VBsOwDc6MRNXmGFfJf2WLUx3PmFVP9z4i9ZHVyBgF4lrE-aS5UIXtG5kzuST9VP01SzcOkeYBmF1jck3oMf9_v8LqntFq1adgGcBhzKa_wnhgLw/s640/papyrus%20reed.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="457" data-original-width="640" height="286" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQ3jpFPMsyXaWZ-b8dSE6oepH_tfGkX7-ZJwsfep79b0-fMcnfPfKnORbXevDObG06XLpSAcTrWO6VBsOwDc6MRNXmGFfJf2WLUx3PmFVP9z4i9ZHVyBgF4lrE-aS5UIXtG5kzuST9VP01SzcOkeYBmF1jck3oMf9_v8LqntFq1adgGcBhzKa_wnhgLw/w400-h286/papyrus%20reed.jpg" width="400" /></a></div><div style="text-align: center;">(Papyrus reed)</div><div style="font-family: Calibri, sans-serif; font-size: large; text-align: left;">Papyrus reed (Cyperus papyrus)</div>

Another important alien invasive species is called Papyrus reed.
This water plant is very tall, sometimes up to 15 feet. It has a triangular
shaped stem and ribbon-like leaves. The leaves are long and narrow. The mode of
propagation for this plant is through rhyzomes. The rhyzomes are underground
and can produce new shoots. This plant thrives in wet soil and shallow water. It
takes just 90 days for the plant to mature. This invasive alien species is a
huge problem for the fishing industry. This is because the reeds can clog up
fishing rods, reels, and nets. The plant can inhibit the movement of fish. Is
also serves as a barrier to the level of oxygen in the water. The low levels of
oxygen can affect the health of the fish.<o:p></o:p>

Kariba weed (Salviniamolesta)<o:p></o:p>

Another
type of alien invasive species is called Salviniamolesta. It is commonly called
Kariba weed. The plant is native to South America and can propagate and spread very
quickly when first introduced to new bodies of water. The Kariba weed has a
bright green colour and floats freely on the water body forming a dense mat across
the surface of the water. It can grow up to a height of 20cm. The Kariba weed
is easily spread by the wind, birds, and other animals. The weed spreads
quickly to new water bodies and once it is established at a new place, it
overpowers other plants in the area and distorts the biodiversity of the area. Since
Kariba weed can easily and quickly grow and spread over the top of the water.
It is able to hamper the movement of boats on the water. It can also clog
fishing nets and other fishing equipment. Other problems that Kariba weeds can
cause include the ability to clog water in-lets and outflows. Like other alien
invasive species, it can reduce the amount of oxygen in the water and thereby
disturbing the quality of water.<o:p></o:p><div class="separator" style="clear: both; font-family: Calibri, sans-serif; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjLEntM0enbXBBYtBpLzDtSefUIxF-url8_5HZ84lhsQKleXo4ukWZ-jeJwKxIEGVBTBFVIZ2VeJ6aQPGBozoWqkJmmQsJeL9KRQogCOv6ArIeV8Gj27hEKmEetIvbZG9XSh_PHDUsh6PVuS7ApsFTVMi9na58yOzG-xKr2IPANlfJfVFXKbPZYfg0tXw/s640/water%20lettuce.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="427" data-original-width="640" height="268" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjLEntM0enbXBBYtBpLzDtSefUIxF-url8_5HZ84lhsQKleXo4ukWZ-jeJwKxIEGVBTBFVIZ2VeJ6aQPGBozoWqkJmmQsJeL9KRQogCOv6ArIeV8Gj27hEKmEetIvbZG9XSh_PHDUsh6PVuS7ApsFTVMi9na58yOzG-xKr2IPANlfJfVFXKbPZYfg0tXw/w400-h268/water%20lettuce.jpg" width="400" /></a></div><div style="text-align: center;">(Water lettuce)</div><div style="text-align: left;"> </div><div style="text-align: left;">Water lettuce (Pistiastratiotes)</div>

There
is also another invasive alien speices, Pistia stratiotes, commonly called water
lettuce. This is a floating aquatic plant. Its colour is bright green. It has
an oval-shape. This plant is native to tropical areas in Africa and in Asia.
Its mode of seed dispersal is by the wind and water. Its seeds are dispersed by
wind and water. New plants of the water lettuce can also be formed through the
small fragments of stem, root, or leaf. For a healthy growth, water lettuce
needs light, nutrients, and good temperature. In about two weeks. Water lettuce
is a huge problem for fish habitat and an interference fish life. The reason is
that it can clog the motors of boats. It reduces the oxygen levels in the water
since it is able to spread and cover the surface of the water. Once oxygen
level is reduced, aquatic life is affected because it reduces the amount of
food left for other life forms including those of fish. <o:p></o:p>

Hornwort (Ceratophyllum sp.) <o:p></o:p>

Hornwort
is also an invasive alien species worth mentioning in this discussion. It is
common in still or slow-moving freshwater habitats. The plant is green. It does
not have true roots, stems and leaves, like other plants. Rather, it is made up
of flattened shoots. These shoots branch out from a central stem. The floats in
water. It is propagated by substrate. Hornwort is problem for fish habitat.
Since it grows quickly and is able spread much faster, it covers the surface of
the water and blocks sunlight. This reduces the level of oxygen in the water.
This is a big problem to fish because they cannot easily find their way around
to be able to find food. They are also not able to avoid their predators.<o:p></o:p>

Conclusion<o:p></o:p>

Alien
invasive species have been identified to cause a lot of damage to the
environment, which can lead to a huge economic loss to aquatic ecosystems and
subsequently great loss to the state. This is only so, if they are not properly
managed. Governments all over the world, including those in Nigeria and Ghana,
must develop strategies to control them if they cannot be prevented. <o:p></o:p>Also read: <a href="https://www.virtualkollage.com/2023/05/the-characteristics-of-fish-habitats-like-freshwater-brackish-water-marine-water-rivers-lagoons-ponds-streams-estuary-pelagic-demersal.html" target="_blank"> The characteristics of fish habitats like freshwater, brackish water and marine water bodies</a><a href="https://www.virtualkollage.com/2023/04/how-to-identify-and-describe-the-common-fisheries-organisms-like-tuna-tilapia-crab.html" target="_blank">How to identify and describe common fisheries organisms</a> <a href="http://www.virtualkollage.com" target="_blank"><<Back to Home Page</a> <a href="https://www.virtualkollage.com/p/list-of-subjects.html?m=1" target="_blank">Go to the list of other subjects>></a> <a href="https://www.virtualkollage.com/p/fisheries-fisheries-syllabus-has-been.html" target="_blank">Go to the list of other topics in fisheries</a>
