  Fish samples (401) were collected weekly between May to July 2015 from commercial catches in the Nyanza Gulf of Lake Victoria, Kenya. The Fork length (cm FL), weight (g) and sex were determined. A total of 288 (71.8%) were female while 107 (26.7%) were males, sex ratio; 1.0:2.7 (male: female). Size of females ranged from 9.0 cm to 17.6 cm FL, mean (± SD) 13.6 cm ± 1.3 cm FL and weighed between 13.0 g and 99.0 g, mean 47.5 g ± 13.9 g. Length of males ranged from 7.0 cm to 15.6 cm FL, mean 12.8 cm ± 1.3 cm FL and weighed between 7.0 and 62.0 g, mean 36.2 g ± 9.9 g. Sex dimorphism was observed as female fish were significantly larger than males (p<0.05). The length frequency showed a unimodal distribution with modal class at 13 cm FL. Male, female and both sexes showed negative allometric growth pattern (b<3). The fish had a good condition with va.. View More»
