摘 要: | 目的]研究养殖密度对革胡子鲶生长性能及血清补体C3、C4的影响。方法]以体重(30.71±0.89)g革胡子鲶为试验对象,测定4种养殖密度(35、65、95、125 kg/m3)下革胡子鲶生长性能及血清补体C3、C4的变化。结果]养殖60 d后,随着养殖密度升高,革胡子鲶终末重、日增重均呈下降趋势,其中35 kg/m3与65 kg/m3密度组间差异不显著(P〉0.05)。各密度处理组间饵料系数均无显著差异(P〉0.05)。低密度处理组(35 kg/m3与65 kg/m3)与高密度处理组(95 kg/m3与125 kg/m3)间死亡率差异显著(P〈0.05)。养殖密度对补体C3、C4的影响不显著(P〉0.05)。结论]65 kg/m3可推荐为革胡子鲶的最佳养殖生产密度。

Abstract: | Objective] The effects of stocking density on the growth performance and the levels of complement C3,C4 in C.gariepinus were investigated.Method] C.gariepinus weighing(30.71±0.89)g were taken as test objects and the changes of growth performance and complement C3,C4 in the serum of C.gariepinus at four culture densities(35,65,95,125 kg/m3) were measured.Result] After 60 days,the final body weight(BWf) and daily weight gain(DWG) decreased with the increasing of stocking density.There was no significant difference between 35 kg/m3 and 65 kg/m3 treatments(P>0.05).Stocking density did not affect the feed conversion rate(FCR) significantly(P>0.05).Significant difference of the death rate was observed between low density treatments(35 kg/m3 and 65 kg/m3) and high density treatments(95 kg/m3 and 125 kg/m3)(P<0.05).Complement C3 and C4 were not affected by the stocking density significantly(P>0.05).Conclusion] 65 kg/m3 could be recommended as the best culture density in practical aquaculture. |
