不同综合养殖条件对花鲈和刺参生长性能及生化指标的影响OA

The differences in growth performance(GP),survival rate(SR)and non-specific immune enzyme(superoxide dismutase,SOD and lysozyme,LSZ)activity of Lateolabrax maculatus and Apostichopus japonicus under different density and water depth conditions in integrated pond culture that were explored.The scientific experiment was conducted by the pond enclosure comparison method.The results showed that the effect of culture density on the GP of L.maculatus and A.japonicus was significant,but there was no significant effect on their SR,SOD,and LSZ activities(P>0.05).The Ca density,which is 2.0 ind.m-2 for L.maculatus and 5.0 ind.m-2 for A.japonicus,is their suitable integrated pond culture density.Within the experimental water depth range,the differences in growth parameters,SR,and non-specific immune enzyme(SOD and LSZ)activities of integrated breeding animals at different depths were not significant(P>0.05).However,the GP of L.maculatus showed a gradually increasing trend with increasing water depth,while A.japonicus was the opposite.2.0 m is the suitable water depth for the integrated pond culture of L.maculatus and A.japonicus.This study accumulated useful technical data for the development and application of the integrated multitrophic aquaculture model in seawater ponds.
