凡纳滨对虾混养点带石斑鱼的研究

Study on the Mixed Culture of Litopenaeus vannamei and Epinephelus malabaricus

[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3 000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3 149.0 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 malabaricus.[Method]Using the biological prevention principle,Litopenaeus vannamei was mixed in the culture of E.malabaricus to study its effects on the yield and survival rate of E.malabaricus.[Result] When the density of L.vannamei mixed with E.malabaricus was about 3 000 per hectare,both the survival rate and yield of E.malabaricus 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 L.vannamei in the culture of E.malabaricus could reduce the occurrence of disease and pests and decrease the culture risk.
