Physiochemical Characteristics of Four commercial Nile Fish

Abstract

This study was undertaken to investigate composition and filleting yield of four commercial freshwater fish species landed in Elmawrada fish market at Khartoum State to know the is it nutritional value and possible conversion into value added food products, according to their composition variation. The study was conducted at the Central Laboratory of Fish Biology at Sudan University of Science and Technology, Sudan. Fourteen fresh samples of (Nile Tilapia, Cat fish, Bagrus sp and Nile perch) were taken from El-Mawrada fish market, Omdurman. The samples stored in ice container and transferred to the Soba Laboratory Center in south Khartoum State for preparation and process to measure characteristics and proximate composition of fish muscles and carcass. The fish samples analyzed presented highest to lowest amounts of fillet (f) in the order: Lates niloticus> C. spp> B. bayad; and lowest amounts of fillet found in Oreochromis niloticus. Statistical analysis will be performed using the Analysis of variance one way (ANOVA) and Duncan’s multiple Range Test, to determine differences between treatments means at significance rate of P < 0.05. The standard deviation of treatment means was also estimated. All statistics will carryout using Statistical Analysis program (SPSS,16). Keywords: proximate, Nile fish, filleting, Body Waite.
