FISHERY Or Fisheries IS THE ART of rearing and keeping fish for the purpose of consumption and industrial uses. understanding the place of the fishery is key as it is a major component of a balanced diet and human nutrients. fishery involves fishing in natural waters like aquatic habitats or the practice of keeping fishponds. Importance of fish farming, Fish farming is important to man,
Fisheries are an important source of food and income for people around the world. They provide jobs for millions of people and play a critical role in supporting coastal communities and economies. However, overfishing and unsustainable fishing practices are threatening the health and productivity of our oceans, and the future of our fisheries.
A fishery is an area where fish and other aquatic animals are caught for commercial, recreational, or subsistence purposes. Fisheries can be divided into two categories: wild capture fisheries and aquaculture, or fish farming. Wild capture fisheries involve the harvesting of fish from the ocean or freshwater bodies, while aquaculture involves the breeding and raising of fish in tanks or ponds.
Fisheries provide a variety of benefits, including food, employment, and economic opportunities. However, overfishing and unsustainable fishing practices have depleted fish populations and threatened the long-term sustainability of many fisheries. In addition, bycatch, which is the unintentional capture of non-target species, is a major problem in many fisheries and can have serious ecological consequences.
To address these challenges, sustainable fisheries management practices have been developed to ensure that fisheries are managed in a way that is environmentally, socially, and economically sustainable. These practices include regulations on the size and number of fish that can be caught, as well as limits on the fishing effort and the use of fishing gear that minimizes bycatch.
Another important aspect of sustainable fisheries management is the development of marine protected areas (MPAs). MPAs are areas of the ocean where fishing and other activities are restricted or prohibited in order to protect marine biodiversity and allow fish populations to recover. MPAs can also provide important ecological and economic benefits by increasing the productivity of nearby fisheries and providing habitat for marine species.
In addition, many fisheries are adopting sustainable aquaculture practices, such as closed-system aquaculture, which involves raising fish in tanks or ponds that are completely closed off from the surrounding environment. This can help reduce the environmental impacts of aquaculture and improve the sustainability of fish farming.
The future of our fisheries depends on our ability to adopt sustainable fishing practices and manage our oceans in a responsible and environmentally sustainable way. This requires a concerted effort from governments, the fishing industry, and consumers to promote sustainable fishing practices, reduce waste and bycatch, and protect the health and productivity of our oceans.
In conclusion, fisheries are an important source of food and income for people around the world. However, overfishing and unsustainable fishing practices are threatening the health and productivity of our oceans and the future of our fisheries. Sustainable fisheries management practices, such as marine protected areas and sustainable aquaculture, can help ensure the long-term sustainability of our fisheries and the health of our oceans.
the importance of fishery and fisheries
1. It is a source of fish for food. Fish is a good source of protein in human diets.
2. It makes good use of the land that would have otherwise. Mailable for arable farming.
3. It serves as a source of employment for fish farmers,
4. It reduces the pressure of fishing in natural waters e.g. rivers, and lakes.
5. It serves as a source of income for fish farmers and traders. importance of agriculture here
6. Fish farming can lead to the improvement of natural fish stocks Likes, rivers etc. since the young ones can be raised in It heries and used for restocking, trips in the production of sports fish, ii Fish can be produced for use in industrial fishing.

Classification of Fishes
there are several types of fish found across the world but each of the can only be found in certain habitats or biomes. so the following are some of the ways Fishes can be classified accordingly
(b) Morphology. this type of classification has to do with the body nature of the fish.

classification of fishes According to Habitat.
Habitat refers to the living environment of an organism. Fishes water. There are three kinds of water habitats in which fishes are fresh water, salt water and estuarine
(a) Freshwater habitat: This refers to water which contains no salt. Such water is found in springs, rivers, ponds, lakes, etc.
Fishes that are found in freshwater habitats are called freshwater fishes .read more on freshwater fishes here Examples include electric fish, moon fish, catfish as clarias and heterobranchus longifilis, gymnarchus niloticus, and tilapia spp.
(b) Saltwater or marine habitat: this refers to a water body that has a salt taste. Its salt content is about 3% per volume of water. Such water can be found in seas and oceans. Fishes found in saltwater or marine habitat are called saltwater or marine fishes. Examples include sharks, mackerels, herring, sardine, and cod (stockfish) are FISHERY
(c) Estuarine habitat: this refers to water found in estuarine where rivers flow into the seas or ocean. An example is the Niger Delta of Nigeria. The salt content of this habitat is in between the content of the freshwater habitat and the marine habitat.
Fishes may not permanently live in this kind of habitat as some do migrate from freshwater or from salt water into the estuaries and go back thereafter. An example of such fish is mudfish.
classification of fishes According to morphology
This has to do with the form or structure of the fish. There are two categories in this class
(a) Nature of bone: Fishes can be classified according to the nature of the body
(i) Bony fishes; These possess bony skeletons or hard bones. Examples include Tilapia, mudfish, and catfish.
(ii) Cartilaginous fishes: These possess solid bones or what is called cartilage (Biscuit bone). Examples include sharks; dogfish.
(b) Nature of body covering: Based on this, fishes can be classified into:
(i) Scaly fishes: These have their body, parts of their head and tails covered by scales which overlap, pointing towards the tail end of the fish. An example is the tilapia galilaeus
(ii) Non-scaly fishes- These have no scales. They have smooth shiny skins. Examples are dogfish, mudfish, and mackerels.
Other Aquatic Food Organisms and FISHERY
There are many other organisms that live in water2. Molluscs such as river snails, periwinkle, and oyster. They are usually covered with shells and these shells serve some useful purposes to man, in addition to their meat.
3. Reptiles such as river snakes, turtles, etc.
4. Mammals such as Hippopotamus, don’t forget to use the comment box and leave a message or suggestion and we will get back to you within seconds. You can read some of the most interesting FISHERY topics below
