A COMPARATIVE ANALYSIS OF CAPTURE FISHERIES ON THE WESTERN AND EASTERN SHORES OF KAINJI LAKE BASIN, NIGERIA

Abstract

The study examined fish catch on Kainji Lake in Nigeria. The data for the analysis were obtained through a sample survey of the lake basin.. A total of 252 fishermen were sampled. Multiple regression analysis was adopted in analyzing the data.. The results obtained indicate that on both shores of the lake, family labour, capital expenses, motorized operation, credit and apprentiship or training are significant factors affecting fish catch by the fish-folks.. Family labour has a negative sign. This implies over utilization of this input. Family labour input can thus be reduced without affecting the catch level. The pooled data for the two shores produced a similar result. The catch functions are characterized by decreasing returns to scale.. The Chow's test for equality of parameters of the catch functions indicated no significant difference between the shores.. It is recommended that a reduction in family labour be encouraged among the fishermen. They should be enlightened on the possibility of over-fishing the lake. The provision of credit to the fishermen is also recommended.



Key - words: Catch function; capture fisheries, returns to scale, Kainji Lake, Nigeria.
