摘　　要：为了探讨微生态制剂对刺参(Apostichopus japonicus)养殖的影响效果,在幼参培育水体中定期加入微生态制剂,通过60 d的培育试验,对比分析了实验组与对照组的水质指标和幼参的生长指标。结果显示,微生态制剂能显著降低水体中的氨态氮(P<0.05)和亚硝酸态氮(P<0.05),对稳定pH和分解有机物等具有积极作用。试验组的幼参成活率与对照组相比均有显著提高(P<0.05),其中试验Ⅱ组(芽孢杆菌加入组)对幼参生长作用显著(P<0.05),但与试验Ⅲ组(乳酸菌加入组)差异不显著(P>0.05)。该试验结果可为微生态制剂在海珍品育苗和养殖中的应用提供参考。In order to explore the effect of microecologics on the culture of Apostichopus japonicus,microecologics were added to the breeding water of juvenile sea cucumber regularly.Through 120 days of cultivation experiment,the water quality indexes and growth indexes of juvenile sea cucumber between the experimental group and the control group were compared and analyzed.The results showed that the microecologics could significantly reduce ammonia nitrogen(P<0.05)and nitrite nitrogen(P<0.05),and had positive effects on stabilization of pH and decomposition of organic.Compared with the control group,the survival rate of juvenile Apostichopus japonicus in experimental groups was significantly increased(P<0.05),and the growth effect of experiment groupⅡ(Bacillus)on juvenile Apostichopus japonicus was significant(P<0.05),but there was no significant difference between experiment groupⅡand experiment groupⅢ(lactic acid bacteria)(P>0.05).The results of this experiment could provide reference for the application of microecologics in the breeding and culture of marine economic animal.
