A Comparative study on the chemical and Biometrical measurements of Wild & Cultivated African catfish (Clarias gariepinus ) in Sudan

Abstract

This investigation was conducted to study fish species African Catfish (Clarias gariepinus)with the objective of comparing the proximate analysis and biometry measurement of farmed fish collected from Elseilad fish farm ministry of Agriculture and Animal wealth irrigation with their natural counter part of Nile River which was collected from Almorada fish market . A total of 18 fish of each group was randomly obtained fresh from fish farm and Almorda fish market . Each group was chemically analyzed and was subjected concurrently to body weight and length measurement relationship . The chemical composition analysis of major body constituents of studied fish ( Protein, Fat , Moisture, dry matter , ash and NFE were determined. Protein and Fat contents level were found to be insignificantly different (p< 0.05) while the moisture and Ash content level was found to be significantly different .The study of standard length , total length ,fork length revealed a high variation and recorded a high significant different (P>0.01)within studied groups in total length, standard length and fork lengt.
