| 摘 要： | 试验分析了投喂卤虫无节幼体条件下黄颡鱼(Pseudogrus fulvidraco)仔稚鱼生长、存活率、摄食力和体成分的变化。随着仔稚鱼的生长和发育,摄食率和胃充塞度逐渐加大,体长大于10 mm的仔鱼,摄食率都在93.3%以上,大多数个体胃充塞度都在3～5级。投喂卤虫无节幼体的黄颡鱼仔稚鱼生长较传统育苗方式生长快,存活率高。体内粗养分、氨基酸与脂肪酸含量都发生相应变化。黄颡鱼淀粉酶、蛋白酶与脂肪酶活性均在1日龄时即可检测到,开口期即5日龄时,3种消化酶比活力均达到较高值,15日龄后消化酶比活力又都降低到较低水平。卤虫无节幼体体内营养物质含量丰富,大小适口,是黄颡鱼仔稚鱼开口摄食的优质生物饵料。
