dc.description.abstractBackground: The objective of this work is to quantify the body weight, body depth and standard length relationship of Oreochromis niloticus, Sarotherodon galilaeus from the Nile and its tributaries to find out the population of best traits. Methods: Fish body weight was recorded to 0.1gm using an electronic field balance. The standard length and body depth were measured using a measuring tape to the nearest cm. Results: The standard length-body weight relationship of O. niloticus and S. galilaeus 15 populations, was significant (p<0.05 top<0.001), except for S. galilaeus populations from Wad Medani and Shendi (p>0.05). The growth mode of the different populations of O. niloticus and S. galilaeus ranged from negative allometric, isometric to positive allometric.The standard length-body depth relationship of O. niloticus and S. galilaeus was mostly significant (p<0.05 top<0.001 Conclusions: The study concluded that there is a relatively high level of polymorphism and genetic diversity within and between O. niloticus and S. galilaeus and a comparatively high overall interspecies pair wise divergence. The population of O. niloticus from Al Kalakla is quite different from other populations, and thus can be recommended for improvement of other tilapias varieties.
