摘    要:为减少高密度养殖下菲牛蛭(Hirudinaria manillensis)疾病发生和养殖废水排放,研究比较了3种商品化有益微生物制剂(硝化细菌T1、光合细菌T2和EM复合菌T3)对养殖水体的净化效果。结果表明,3种有益微生物制剂在15d内均能使养殖水体的pH稳定在6.8以上,溶氧量(DO)分别比对照组提高30.12%、26.95%和46.12%;化学耗氧量(COD)分别比对照组低1.02mg/L、1.13mg/L和1.53mg/L;3个处理组对氨氮(NH4+-N)的平均降解率分别为48.48%、45.23%和63.10%,亚硝态氮(NO2-N)平均值分别比对照组低0.16mg/L、0.19mg/L和0.27mg/L;菲牛蛭存活率均高达90%以上,明显高于对照组的53%。3种有益微生物制剂均有显著增加溶氧量、降低氨氮、亚硝态氮和化学耗氧量的效应,对菲牛蛭养殖水体均具有很好的净化作用,其中以EM复合菌效果最佳。

关 键 词:菲牛蛭  有益微生物  理化因子  成活率

Abstract:In order to supply feasible basis for water quality control by active microbial agent,and decrease the disease and the discharge of aquaculture wastewater of the leech,Hirudinaria manillensis cultured at high density,three profitable microbes were applied to study their effects on the aquaculture water quality. The results showed that the three profitable microbes all could stabilize pH over 6.8 within 15 days,and increase the DO content by 30.12 % (T1),26.95 % (T2) and 46.12 % (T3),respectively compared wi...
