摘要:

研究团队构建了“两坝三区”即“沉淀区-溢流坝-生态区-潜流坝-曝气区”耦合循环水生态养殖体系,并采用该尾水处理模式对全国九省市淡水养殖池塘进行了生态化改造。为探究改造是否具有提升鱼类免疫能力,本研究以吉富罗非鱼为研究对象,比较养殖尾水未处理与处理组血清中几种免疫因子含量的变化规律,并解决应用过程中成本核算这一产业关键问题。结果表明,处理过后的养殖尾水,并不会影响该批鱼特定生长率SGR和肝体指数HSI(P>0.05),且对鱼体的生长指标无显著性影响(P>0.05)。血清免疫因子α1-AT和LYS含量,促炎因子(IFN-γ)和抗炎因子(IL-10和TGF-β)含量均显著增加(P<0.05)。研究发现,不同处理之间的罗非鱼生长差异与尾水浓度无关,养殖尾水处理后罗非鱼血清中几种免疫因子含量变化显著,可能通过激活巨噬细胞增强分泌型炎症因子,持续提高了其免疫能力。

Abstract:

The team adopted the model of two dams and three zones to carry out ecological transformation of ponds in the Yangtze River Delta. In order to explore whether the transformation can improve the immune ability of fish, this study compared the changes of several immune factors in the serum of genetic improvement of farmed tilapia (GIFT) in the untreated and treated groups of waste water, and solved the key industrial problem of cost accounting in the application of the two dam and three zone model. Results showed that the treated aquaculture waste water would not affect the SGR and HSI of the tilapia, and had no significant effect on the growth index of the fish (P>0.05). The levels of immune factors α1-AT and LYS in GIFT were significantly increased, and the contents of pro-inflammatory factors (IFN-γ) and anti-inflammatory factors (IL-10 and TGF-β) were significantly increased (P<0.05). Significant changes in the levels of several immune factors have been observed in tilapia serum after treatment of aquaculture wastewater.
