利用对虾养殖高位池进行棕点石斑鱼(Epinephelus fuscoguttatus)仔、稚鱼和鱼苗中间培育试验。共进行5批育苗试验,其中每批购受精卵量均为1 kg,平均孵化率为91.5%,5批共孵出仔鱼593.5万尾。共培育出体长2~3 cm的鱼苗82.3万尾,仔鱼平均育苗成活率为13.9%。5批鱼苗进行池塘网箱培育试验,共培育出体长8~10 cm的大规格鱼种70.9万尾,中间培育平均成活率为85.4%。
Epinephelus fuscoguttatus, intermediate larvae and fry breeding experiments were conducted using shrimp aquaculture cells. A total of five batches of nursery experiments were conducted, in which the amount of fertilized eggs per batch was 1 kg and the average hatching rate was 91.5%. In the five batches, 5.935 million larvae were hatched. A total of 82.3 thousand fish fry with 2 ~ 3 cm in length were cultivated, and the average survival rate of larvae was 13.9%. Five batches of fry were cultured in pond cages. A total of 709,000 large-sized fingerlings of 8-10 cm in length were cultivated. The average survival rate in the middle cultivation was 85.4%.
