| Abstract | ||
| This study was conducted during a period of two years (1986 and 1987) in eighteen 7.5 feddan fresh water ponds in Abbassa farm that belongs to the Central Laboratory For Aquaculture, Agricultural Resarch Cente, Egypt. This experiment aimed to study the effect of mullet stocking rate on carcass traits and chemical composition of tilapia flesh (Titania niloticus and Sarotherodon aurea, mullet (Mugil cephalus and Mugil capita) and carp (Cyprinus carpio). Differences in carcass traits due to species, mullet stoking rate and the interaction between them were generally significant (P<0.05 or P<0.01 or P<0.001). Averages of the ' weights of the whole fish, flesh, head, skeleton and viscera in 1986 were the highest for carp followed by mullet and tilapia irrespective of stocking rate. Species differences contributed significantly on most elements of chemical composition of flesh. Mullet stocking rate contributed a signifcant (P<0.01) source of variety only on fat and ash percentages of the first year. | ||
