Última The biology and distribution of Haplochromis spp in the Nyanza Gulf prior to the total invasion of the Gulf of Nile perch, Lates niloticus (L) OceanDocs Mwalo, O.M.. The work reported was conducted during the watershed period of 1976 when Nile perch (Lates niloticus) started to replace Haplochromis spp. in dominance in the Nyanza Gulf of Lake Victoria. Seventy four "groups" of Haplochromis species flock obtained from a stock assessment survey of that year were used in the study. The length of fish examined varied between 57 and 237 mm total length, and between 1 and 182 g wet weight, with means of 101.05 mm and 18.53 g respectively. Frequency distribution curves for both sexes were unimodal with a maximum between 70 and 130 mm. The t-test showed that the two sexes came from the same population. Clutch size per fish (mean weight 25.3 g and mean total length 106.7 mm) was 78 eggs. The minimum size at maturity was 89 mm...
