为比较研究深水网箱养殖军曹鱼中分别投喂软颗粒饲料和冰鲜鱼的养殖效果,选取平均体重93 g的军曹鱼幼鱼在深水网箱内进行了为期10周的养殖试验。试验组投喂软颗粒饲料,对照组投喂冰鲜小杂鱼。结果显示:粗蛋白与粗脂肪含量分别为46.3%和7.6%的软颗粒饲料(干物质)能基本满足军曹鱼的营养需求;与对照组相比,试验组的军曹鱼增重率和特定生长率略低,存活率高9.0%,饲料系数低61.2%,养殖成本高3.85%。研究结果表明,投喂软颗粒饲料的养殖效果与冰鲜鱼相近,存活率更高,更具环保效益。
為比較研究深水網箱養殖軍曹魚中分彆投餵軟顆粒飼料和冰鮮魚的養殖效果,選取平均體重93 g的軍曹魚幼魚在深水網箱內進行瞭為期10週的養殖試驗。試驗組投餵軟顆粒飼料,對照組投餵冰鮮小雜魚。結果顯示:粗蛋白與粗脂肪含量分彆為46.3%和7.6%的軟顆粒飼料(榦物質)能基本滿足軍曹魚的營養需求;與對照組相比,試驗組的軍曹魚增重率和特定生長率略低,存活率高9.0%,飼料繫數低61.2%,養殖成本高3.85%。研究結果錶明,投餵軟顆粒飼料的養殖效果與冰鮮魚相近,存活率更高,更具環保效益。

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 .
