Systems of Fishery

There are THREE major systems of fisheries in Nigeria. These are:

  1. Small scale fisheries
  2. Large scale fisheries (industrial fisheries)
  3. Aquaculture


Small Scale Fisheries

This is commonly practiced by local fishermen who live in fishing camps along the banks of the rivers, ponds or streams or along the coast of the sea. Small scale fisheries are very important because between 50-90% of all the fish consumed in the country come from it. Some of the features of small scale fisheries include:

  1. The fisher folks use simple equipment.
  2. They catch the fish by simple methods
  3. They catch small quantity of fish.

Large Scale or Industrial Fishery

This practice involves catching fish using large boat called TRAWLERS from natural water bodies. It is carried out on large inland rivers lakes and in the oceans. Large scale fisheries have the following features:

  1. It involves the use of complicated and expensive equipment.
  2. It is expensive to set up and operate.
  3. It is carried out in the sea/ocean or in very large inland lakes.
  4. A large quantity of aquatic animals are caught.


This is otherwise known as fish farming. It is the practice of rearing fish and other aquatic organisms in artificial water bodies known as fish ponds. Aquaculture majorly produces fish in large quantity for eating and also produces beautiful coloured fish for home aquaria.
