摘　　要：在池塘进行军曹鱼Rachycentron canadum人工育苗研究,通过解剖消化肠道以确定仔鱼开口的生物饵料种类。结果显示,个体较大的桡足类无节幼体比轮虫更适合作为军曹鱼仔鱼的开口饵料;对体长和体重进行测定,军曹鱼在鱼塘进行人工育苗,鱼苗生长迅速,7日龄的仔鱼体长达1cm,30d的鱼苗可长至15cm。Study was conducted on artificial breeding of Rachycentron canadum in pond. Through anatomizing the intestine of larvae, the variety of biological diets for initial feeding was decided. The results indicated that the biggish nauplius of Copepod were fitter than Rotatoria in being initial diet of Rachycentron canadurn larvae. According to the measurement of the body length and weight, Rachycentron canadurn grew very well under the condition of pond artificial breading, with the body length of 7 days old larvae and 30 days old seedling reaching 1 centimeter and 15 centimeter, respectively.
