点带石斑鱼

人工育苗条件下点带石斑鱼仔鱼开口期摄食的观察

Observation on the Feeding Habit during the Mouth-open Period of the Larvae of Epinephelus malabaricus ( Bloch Schneider ) under the Artificial Rearing Conditions

经回归分析，点带石斑鱼人工配合饵料中蛋白质适宜含量为52.1%。

The regressional analysis reveals the the suitable content of protein in the artificial diet for Epinephelus malabaricus is52.1 % .

对5种饵料的脂肪酸进行了分析，结果显示，饵料中高度不饱和脂肪酸DHA和EPA的含量之间的比例，对点带石斑鱼幼鱼的生长比其含量本身更加具有明显的影响。

The fatty acid analysis of the 5 diets showed that the content ratios of DHA to EPA were more important factor to influence the growth speed of the fish .

脂肪酶在点带石斑鱼开口之前已具有很强的酶活性，并随着卵黄囊的缩小酶活力逐渐降低。

Lipase has a strong activity from the larvae began to feed , and Enzyme activity decreased with the yolk sac narrowing .
