摘　　要：为掌握循环水养殖模式下适宜子二代中华鲟(Acipenser sinensis)生长的养殖池形,分析了养殖池形对子二代中华鲟生长及血清生理的影响。以平均体质量(2.43±0.19)kg,平均体长(63.77±2.15)cm的子二代中华鲟为试验对象,设计了圆形(YX)、跑道形(PX)和方切角形(FX)3种养殖池形,试验周期为90 d。结果显示:养殖池形对子二代中华鲟的生长影响显著,FX组的中华鲟特定生长率和增重率显著低于YX组和PX组(P<0.05),而饲料系数显著高于其他两组(P<0.05);中华鲟的存活率受养殖池形的影响,FX组的中华鲟存活率低于其他两组;血清生化指标表明,FX组中的谷胱甘肽过氧化物酶(GPX)显著低于其他两组,其他血清生化指标无显著差异(P>0.05);另外,FX组的耗氧率显著高于PX组(P<0.05),而排氨率无显著差异(P>0.05)。研究表明,在循环水养殖系统中设计养殖池时,圆形或跑道形是适宜中华鲟健康生长的鱼池形状。In order to find out the suitable culture pond shape for the growth of second filial generation Acipenser sinensis in the recirculating aquaculture system(RAS),the effects of the culture pond shape on the growth and serum physiology of second filial generation Acipenser sinensis were analyzed.Second filial generation Acipenser sinensis with an average weight of(2.43±0.19)kg and an average body length of(63.77±2.15)cm was selected as the experiment object,and circular(YX),racetrack(PX)and octagonal(FX)culture ponds were designed for an experiment of 90 d.The results showed that the culture pond shape had a significant effect on the growth of second filial generation Acipenser sinensis.The specific growth rate(SGR)and weight gain(WG)rate of Acipenser sinensis in the FX group were significantly lower than those in the YX group and PX group(P<0.05),while the food conversion ratio(FCR)was obviously higher than that in the other two groups(P<0.05).Influenced by the culture pond shape,the survival rate of Acipenser sinensis in the FX group was lower than that in the other two groups.For the serum biochemical indicators,the results showed that the glutathione peroxidase(GPX)in the FX group was significantly lower than that in the other two groups,and there was no obviously difference in other serum biochemical indicators(P>0.05).In addition,the oxygen consumption rate in the FX group was significantly higher than that in the PX group(P<0.05),while the ammonia excretion rate had no obvious difference(P>0.05).The results show that circular or racetrack pond is suitable for healthy growth of Acipenser sinensis in RAS.
