An assessment of the impact of the Nile perch on the fisheries of Lakes Victoria and Kyoga

The combined effects of lack of effective management measures, over-exploitation with destructive fishing gears, and interspecific competition, particularly among tilapiines have had profound effects on the fish stocks of Lakes Victoria and Kyoga. It has been proposed that these have been more important in the decline of the indigenous fisheries than predation or competition from Nile perch. The purpose of this paper is to provide an assessment of the dramatic changes in the fisheries of Lakes Victoria and Kyoga . Both lakes have experienced almost similar changes for which Lates could not have been wholly responsible.
