Impact of Rearing Environment on Chemical Characteristics of Catfish, Khartoum State, Sudan

Abstract : This study was conducted in Khartoum State; the aim of this study was to evaluate Chemical composition of Catfish (Clarias gariepinus) reared in different environments in Khartoum State. A total of 60 samples of catfish (Clarias gariepinus) were collected from Nile river and earthen ponds fish farms around Khartoum State and the samples were subjected to chemical composition analysis (Dry matter (DM%), Crude protein (CP%), Either Extract (EE%) and Crude fiber (CF%) moisture% Nitrogen Free Extract ( N.F.E%) Ph as well as ash %). The data was subjected to statistical analysis (SPSS) by using one way analysis of variance (ANOVA). The findings of this study revealed that, Catfish (C. Gariepinus) from Nile environment has Higher in nutritive values than catfish from earthen pond environments and there was highly significant difference (P≤0.01) except the pH. Accordingly, the study concluded that the fish from Nile River water has a high in nutritive values than earthen pond fish.
