摘　　要：[目的]利用对虾养殖高位池进行棕点石斑鱼人工育苗试验,探索棕点石斑鱼大水体育苗技术,提高育苗的成活率并培育出健壮苗种,缓解当前棕点石斑鱼养殖苗种匮乏问题。[方法]先利用微生物在池中建立稳定平衡的生态系统,然后进行棕点石斑鱼受精卵的孵化和鱼苗培育。[结果]2007和2008年2年中共进行5批育苗试验,共购买棕点石斑鱼受精卵5 kg,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。5批孵化的仔鱼育苗均取得成功,共培育出体长2.0~3.5 cm的鱼苗82.3万尾,仔鱼平均育苗成活率为13.9%。[结论]利用对虾养殖高位池进行棕点石斑鱼仔、稚鱼培育能有效提高鱼卵的孵化率、育苗的成活率和减少互相残食,因此该育苗技术是可行的。[Objective] The technique of brown-spotted grouper fry-raising at large water area was explored through the experiment in its artificial fry-raising at the high-level pool for brown shrimp-breeding for the improvement of the survival rate of strong fry so that the issue in the scarcity of its fry in current raising production.[Method] The brown spotted groupers were fertilized and the eggs were cultured for fry-raising in the pond,which ecosystem was stabilized and balanced with microorganisms.[Results] For two years nursery Communist China in 5 batches of experiment in the fry-raising in 2007 and 2008 were conducted and total of 5 kg fertilized eggs was purchased for the experiment.1 kg fertilized egg was experimented in each batch and the average hatching rate was 91.5%.Total of 5.935 million fries were hatched in 5 batches of experiments and the fry-raising from the 5 batches was also successful,so that total of 823 000 fishes with body length of 2.0-3.5 cm were cultured and the average survival rate of fry was 13.9%.[Conclusion] The culturing technique was with high hatching rate of eggs,survival rate of fry and low killing rate among each other,which was feasible.
