[目的]提高凡纳滨对虾的产量.[方法]利用生物防病原理,在凡纳滨对虾养殖中混养点带石斑鱼,研究其对凡纳滨对虾存活率和产量的影响.[结果]当凡纳滨对虾中混养点带石斑鱼密度为3000 尾/hm2左右时,凡纳滨对虾存活率和产量均达到最高,比单一养殖凡纳滨对虾存活率提高11.49％,平均产量提高3149.O kg/hm2.[结论]在凡纳滨对虾养殖中混养点带石斑鱼,能起到减少病害发生和降低养殖风险的作用.%[ Objective] The research aimed to improve the yield of Epinephelus malabarkus. [ Method] Using the biological prevention principle , Litopenaeus vannamei was mixed in the culture of E. Malabarkus to study its effects on the yield and survival rate of E. Malabarkus. [Result] When the density of I. Vannamei mixed with E. Malabarkus was about 3 000 per hectare, both the survival rate and yield of E. Malabarkus were the highest. Compared with only breeding E. Malabaricus, the survival rate increased by 11.49% and the average yield increased 3 149.0 kg/hm2. [Conclusion] Mixing I. Vannamei in the culture of E. Malabaricus could reduce the occurrence of disease and pests and decrease the culture risk.
