According to the results, after cultiva- tion for 25-30 d, the survival rate of P. fulvidraco was 33%-52%, the average size was 900-1300 individuals/kg, and the feed conversion ratio was 0.50-0.80; small cultivating ponds exhibited low stocking density of P. fulvidraco, resulting in high survival rate, large size and low feed conversion ratio.展开更多
