Reproductive biology of Oreochromis niloticus in Lake Beseka, Ethiopia

Reproductive biology of Oreochromis niloticus in Beseka was studied. Samples of O.niloticus were collected monthly during September 2010 to August 2011 using different centimeter mesh sizes of gillnets. The relationship between total length and total weight was curvilinear and sex ratio was different throughout the sampling periods. The 50% sexual maturity length (L50) was estimated at 14 cm TL...
