Abstract
Bahr Shebeen canal (BSC) and Khadraweya canal (KHC) are two
Nilotic canals, the first is less polluted and the second is polluted.
Oreochromis niloticus is the major fish species in the Nile and its
branches, and consequently, this study is carried out on their biological
parameters are studied to investigate the effect of pollution in those
habitats. These included: various parameters of growth, mortality, survival
rates, stomach-somatic index, gonado-somatic index, and hepato-somatic
index. It was found that there is a significant decline in those parameters in
the fish of KHC, as compared to BSC, which could be tied to pollution in
that canal.
