摘要:

为探明MABR膜与微生态制剂在河蟹养殖过程中带来的不同影响,本研究以扣蟹培育阶段作为背景条件,在河蟹养殖池塘中分别使用MABR膜和微生态制剂,通过测定水质理化指标,浮游生物定量分析,河蟹营养品质分析,探究两种水处理方式对于河蟹养殖池塘水质和河蟹营养品质的影响及潜在机制。结果表明,与CK组相比,Ⅱ组的方式对于水质改善效果最好,在不同程度上降低了池塘水体中的氨氮、亚硝、总磷、总氮、COD的含量,同时,所培育河蟹粗蛋白和粗脂肪含量都显著高于对照组(P<0.05),且总氨基酸和必须氨基酸含量最高(P<0.05)。而Ⅰ组方式可显著增加浮游生物量(P<0.05),且必须氨基酸含量/总氨基酸含量显著高于对照组(P<0.05)。综上所述,MABR膜与微生态制剂的使用可以一定程度上改善河蟹养殖池塘的水质,并且还可提高所培育河蟹的营养品质。

Abstract:

In order to investigate the different effects brought by MABR membrane and microecological preparation in the process of Eriocheir sinensis culture, we used MABR membrane and microecological preparations in Eriocheir sinensis culture ponds under the background conditions of juvenile crabs cultivation stage, and investigated the effects and potential mechanisms of the two water treatments on the water quality and nutritional quality of Eriocheir sinensis in the culture ponds through the determination of physical and chemical indexes of water quality, quantitative analysis of phytoplankton, and nutritional quality analysis of Eriocheir sinensis. The results showed that compared with the CK group, the group II approach had the best effect on the improvement of water quality, and reduced the content of ammonia nitrogen, nitrite, total phosphorus, total nitrogen, and COD in the pond water to different degrees; meanwhile, crude protein of the cultivated river crabs and crude fat contents were significantly higher than those of the control group (P<0.05), and the contents of total amino acids and essential amino acids were the highest (P<0.05). While the group I approach significantly increased the plankton biomass (P<0.05), and the content of essential amino acids/total amino acids was significantly higher than that of the control group (P<0.05). In conclusion, the use of MABR membrane and microecological agents can improve the water quality of Eriocheir sinensis culture ponds to a certain extent, and can also improve the nutritional quality of the cultivated Eriocheir sinensis.
