摘要
本实验用牡蛎幼虫、轮虫以及卤虫无节幼体投喂黑鲷仔稚鱼,观察摄食情况。消化道内含物分析结果表明,孵出后3周日至6周日,主要摄食牡蛎幼虫;9周日至19周日主要摄食轮虫;20周日以后主要摄食卤虫无节幼体。3种饵料中,初次摄食的最适宜饵料是牡蛎幼虫。
In rearing marine fish larvae, first feeding is important for the survival rate. In this experiment, black porgy larvae were fed on oyster trochore larvae, rotifers and artemia na-uplii. Analysis of the food in the fry intestine showed that 3 to 6 days old black porgy fed mainly on oyster trochore larvae, 7 to19 days old fed mainly on rotifers and 20-day old and onwards mainly on artemia nauplii. Of the three kinds of live food, the most suitable one for the first feeding black porgy larvae is the oyster trochophore larvae.
