为建立低消耗、低排放、高效益的新型养殖模式,在鳜养殖池塘引入微生物、水生植物以及投放其他鱼种进行生产试验。在0.2 hm2鱼池中,投放4 cm鳜鱼种2790尾,经过185 d的饲养,单产达到415 kg/667m2。鳜池连同饵料鱼池共0.65 hm2面积,平均利润3977元/667m2,商品率90%。在局部生态系统条件下,池塘水质实现了自净,水质指标符合鳜生长要求,养殖用水比常规养殖相对减少。 In order to establish a new low-cost, low-emission and high-efficiency farming model, micro-organisms, aquatic plants and other fish species were introduced into aquaculture ponds for production tests. In 0.2 hm2 fish ponds, 2790 4 cm minnows were put into operation, and after 185 days, the yield reached 415 kg / 667m2. Mianchi together with bait fish pond a total area of ​​0.65 hm2, the average profit of 3977 yuan / 667m2, product rate of 90%. Under the condition of local ecosystem, the water quality of the pond is self-purification, and the water quality index accords with the growth requirement of the shrimp. The water for breeding is relatively less than that of the conventional culture.
