Comparision of feeding cobia (Rachycentron ca nadum) with moist pellet feed and frozen trash fish in deep-water cages
摘要
Abstract
In order to compare the feeding effect of moist pellet feed and frozen trash fish on cobia ( Rachycentron canadum) , the10-week culture trial was conducted, in which the juvenile cobia with an average weight of 93 g were cultured in deep-water cages .The results showed that: the moist pellet feed with crude protein and crude fat content of 46 .3%and 7 .6%respectively ( on dry matter basis ) , could basically met the nutritional requirements of the cobia .Compared with the frozen fish group , the weight gain rate ( WGR ) , specific growth rate ( SGR) of cobia in the moist pellet feed group were slightly lower , with the survival rate ( SR ) higher by 9 .0%, the feed coefficient rate decreased by 61 .2%, and the production cost ( per kilogram) slightly higher by 3.85%.Above all, the results indicated the feeding effect of moist pellet breeding on cobia was similar to that of frozen trash fish , and had the characteristics of high survival rate , high effectiveness and environmental protection .关键词
