A contribution to the study of Lates niloticus, Nile perch, in Lake Chad

Lales niloticus, the Nile perch, supports an economically important gillnet fishery in Lake Chad where it contributes from 35 to 45 per cent by weight of commercial landings at Malamfatori on the North-Western shore of the Lake. The present study examin s changes in the size distribution of Lates niloticus and variation in its catch rate expressed as catch kg/lOO m2 net/night fishing from the inshore to about 20-mile offshore waters of the lake at Malamfatori. Some meristic and morphometric characters of the fish have also been examined as a contribution to its racial characteristics
