通过合理调整放养模式、设置风眼莲净化水质、提高苗种质量、全程使用微生态制剂等综合技术措施实施斑点叉尾鮰健康生态养殖。结果表明,试验池亩产513.5㎏,成活率95.1%,产品品质达到商检出口检验标准。单产平均增加24.9%,成活率提高10.6%,试验塘的水质相对对照池塘有明显的改善,其中亚硝酸盐氮降低43%,氨氮降低52%。
Through the rational adjustment of stocking patterns, Eichhornia crassipes purify water quality, improve the quality of seedlings, the whole process of using probiotics and other comprehensive technical measures to implement Channel Catfish 鮰 healthy ecological farming. The results showed that the test pond mu yield 513.5㎏, survival rate of 95.1%, the product quality inspection inspection standards. The average yield per unit area increased by 24.9% and the survival rate increased by 10.6%. The water quality of the experimental ponds was significantly improved compared with that of the control ponds. Nitrite nitrogen decreased by 43% and ammonia nitrogen decreased by 52%.
