Abstract

In order to study the effects of different aquaculture modes on growth, digestive enzyme activity and non-specific immunity of E. fuscoguttatus♀×E. lanceolatus♂, 360 healthy E. fuscoguttatus♀×E. lanceolatus♂ with initial weight of (143.22±12.48) g were selected and randomly assigned into industrial recirculating aquaculture (Group A), cage aquaculture in pond (Group B) and aquaculture in flowing water (Group C) for 56 days of test. The results showed that the survival rate, weight gain ratio and specific growth ratio , as well as GH and IGF - I in Group B were significantly higher than those in Group A and Group C (P<0.05), but the FCR in Group B was significantly lower than that in Group A and Group C (P<0.05). The activities of amylase and lipase in Group B were significantly higher than those in Group A and Group C (P<0.05), and the activity of protease in Group B and Group C was significantly higher than that in Group A (P<0.05). The content of MDA in Group B was significantly higher than that in Group A and Group C (P<0.05), and the content of LZM and the activity of SOD in Group A were significantly higher than those in Group B and Group C (P<0.05). The study shows that cage aquaculture in pond can better promote the growth and digestion of E. fuscoguttatus♀×E. lanceolatus♂, while industrial recirculating aquaculture is more conducive to improving the immunity.

Key words： aquaculture mode; E. fuscoguttatus♀×E. lanceolatus♂; growth; digestive enzyme; non-specific immunity
