Topic Content:

  • Methods of Fishing (Netting, Hook and Line, Impaling, Basket, etc.)

(i) Netting:

This involves the use of nets thrown into the rivers, lakes, and oceans to catch fish. Fishing nets include; cast nets, trawl nets, dip nets, gill nets, bag nets, scoop nets, seine nets, etc.

Nets are made from fine cotton or nylon thread. Netting equipment is lowered into the water with a small weight hung all over the edges of the net to help it sink to the bottom of the water. When the net is pulled up, it encloses many fishes which are trapped within the net.

Types of Nets:

Scoop net: After the pond has been drained, harvesting can be done with a scoop net.

Gill Net: These nets are used to harvest or catch bigger fish(es) in a pond. Thus leaving the smaller fish(es) until they attain bigger sizes. Gill nets are usually made of 2-3 cm mesh sizes.

Seine Net or Drag Net: This net is capable of harvesting all the fishes, both young and mature, because it has a smaller mesh size than gill nets.

Cast Net: When a fish is sighted, a cast net is thrown into the water. It sinks and later encloses the fish. The net is drawn carefully with fish trapped inside. Its use requires a boat and great skill in casting.
