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).
