A i R TrawlingS Basket fishing b i Basket fishing- The basket channel shaped to allow easy entry for fish- At the mouth, there is a non-return valve which restricts the outward. The basket isheld in the position with ropes stones sticks downstream- The basket is left in that attracted position for sometime then removed for landing of fish ii Trawling- A bag shaped net is attached to the ship trawler- The nets mouth is kept open by other boards- The upper art if kept a float by corks floats- Weights are used to keep the lower parts of the net at the sea bed- The trawler drags along the net- After sufficient fish is caught the net is hauled to the trawlerc - Fishing is restricted to specific reasons to allow for breeding and maturing of fish- Standardizing size of nets to ensure fingerlings are not cangut- Licenses are issued to prospective fishermen to control their number and to ensure there eis no over-fishing- Fish farming is being encouraged to ensure sufficient supply of fish. -. There is restriction of the disposal of untreated waste into the sea- Artificial fertilization is carried out in special hatcheries to sustain the supply of fish restocking of over fished waters3. A i It is the rearing of fish in pondsii - The government through the fisheries department has set up fish ponds andhatcheries as demonstration farmsEstablishment of research institutions to investigate aspects of fish farming breeding diseasesExpansion of markets through intensified campaigns aimed at encouraging more people to eat fishExtension officers have been sent to the field to advise on fish farming techniquesThe government has encouraged the establishment of co-operatives which give credit facilities to fish farmersEstablishment of national food policy which encourages diversification of food aid as source of protein leading to setting up of fish farmsb - Inadequate storage and preservation facilities which cause heavy losses on theanded catch leading to low catchOccurrence of strong sea waves causing accidental drowning destruction of fish vesselsPoor fishing equipment which confine the fishermen to a few metres of continental shelf leading to low catchSparse population in the north coast and alternative economic activities in the south coast that lead to small market for fishHigh prices of fish which discourage many people from eating it regularlyLocal fishermen face stiff competition from foreign fishermen mainly from Korea and Japan who have adequate and advanced facilities for deep sea fishingWarm Mozambique currents and deep continental shelf which discourage the flourishing of fishRegular coastline few sheltered bays hence few sites for fish landing and breeding groundsc i - North-West AtlanticNorth-East AtlanticNorth East pacificNorth West Pacificii - Presence of extensive and shallow continental shelf which allow light to penetrate to the sea bed encouraging the growth of planktons used as fish foodUpwelling of ocean waters caused by convergence of warm Kuroshio and cold Oyashio currents bring minerals for planktons from the sea bed hence attracting fishJapan has indented coastline several bays which provide secure breeding grounds for fishSheltered bays provide suitable site for building ports landing sites e.g.
