Trawling as a method of fishing is;Trawling involves dragging a cone shaped bad (trawl) over the sea bed behind a boat or trawler.A bag shaped net attached to the ship trawler is dragged along the sea bed to trap the fishThe net is cast into the sea by a trawler.The upper part of the net is kept a float by floats and the bottom held down by weights.Then it is dragged on the sea bottom at low speed.The mouth of the net is kept open by the floats and weights.Fish swim into the net and trapped in.Once enough fish is caught the net is hauled into the trawler and the fish is removed.
Reasons marine fishing less developed in East Africa are;Inadequate capital to purchase the required equipmentSmall market for the marine fish due to sparse population along the coast.There is stiff competition from foreign fishermen.Warm water/tropical location discouraged fish breeding.Narrow continental shelf at the coast resulting to low plankton growthUse of small boats/poor technology discouraged deep sea fishing.
Reasons why fresh water fishing is more popular than marine fishing in East Africa are;There are enormous fishing grounds e.g. L. Victoria, L Albert, L. Naivasha, L Tanganyika which are accessible to many people.Fresh water fish are popular with high demand among the people encouraging more inland fishing.Fresh water fishing requires simpler methods affordable by majority of fisherman in E. Africa.Most inland fishing ground are rich in Plankton hence encouraging fish breeding.High population in some places such a L. Vitoria offers the much need market.Government support e.g. setting up processing plants ad cooing plants have encouraged more fishing.
