There is an intricate link between various fishing techniques and knowledge about the fish and their behaviour including migration, foraging and habitat. The effective use of fishing techniques often depends on this additional knowledge

  1. Methods of Fishing
    There are different methods used to catch fish from the water. These methods include:

(a) Use of nets: Nets are made of nylon and are used for fishing both in large and small bodies of water. Net fishing is very efficient because many fishes can be caught at a time with a net.

There are different forms of net used for fishing.

These are:
(i) The cast or throw nets
(ii) The gill nets
(iii) The lift nets
(iv) The hand net or scoop net (b) Use of hooks: A hook is made of a metal rod which is curved at the tip.

Fishing hooks are of two kinds:
(i) The pole and line hook: This consists of a hook to which twine is tied, which \’in turn, is tied to a long pole or stick.

A weight or float (could be a small stone or metal nut) is tied to the rope to enable the hook go down the water. Fish is attracted to the hook by a bait (e.g. earthworm) attached to it.

When a fish attempts to eat the bait, its mouth is hooked to the hook and the fisher quickly throws out the hook from the water to remove the fish.

The method is time and labour-consuming. Only one fish can be caught with this method it a time.
