Fatty acids (FAs) particularly ω3 and ω6 polyunsaturated fatty acids (PUFAs) play important role in human health. This study aimed to investigate the composition and levels of selected ω3 PUFAs in four commercial fish species, Nile perch (Lates niloticus), Nile tilapia (Oreochromis niloticus), Tilapia zillii, and dagaa (Rastrineobola argentea) from Mwanza Gulf in Lake Victoria. The results indi...

A multiple regression analysis of growth in juvenile tilapia Oreochromis niloticus and 0. aureus (Cichlidac) is presented based on experiments conducted from 1984 to 1987 in recirculating systems a t the Tilapia Genetics Laboratory of the University College of Swansea. Wales, UK. One regression model was derived for 0. niloticus, one for 0. aureua and one for both species jointly. Overall fit, ...

This study was conducted to assess the reproductive biology and early breeding behaviour of female Oreochromis niloticus reared in monoculture and polyculture with Clarias gariepinus in earthen ponds for 8 months. Results revealed no significant difference in length at first maturity (L50) between females reared in monoculture and polyculture systems. Similarly, no significant differences were ...
