| Abstract: | 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. |
