The potential for clupeid fishery in Lake Kainji, Nigeria
The potential for a clupcid fishery in Lake Kainji has been examined using both experimental fishing samples and the results obtained from those of the commercial fishermen. A total annual production of 1,400 tons has been estimated. In money terms, this amounls to N198.800 (£99,400) per annum.This production has been sustained by the abundant zooplankton food available the year round on the lake.Recommendations for the effective methods of cropping clupeids were made, bearing in mind the need to maintain the fishery on a sustained yield basis.The place of c1upeids in the ecology of the lake was examined and on the basis of the evidence available it was recommended that Pellonula afzeluisi could be exploited on a large commercial scale without any adverse effects on the fishery in the lake.
