近年来,池塘养殖常规鱼的产量不断提高,而养殖效益却相对降低,单纯养殖常规鱼平均每667m~2水面的纯利一般在500元左右。为了充分挖掘水体潜力,降低养殖成本,减少投资风险,提高产品质量和池塘的养殖效益。笔者认为在池塘适当套放一些名特品种,在不影响常规鱼类产量的同时,每667m~2水面可 In recent years, the production of conventional aquaculture ponds continued to increase, while the breeding benefits are relatively reduced, the average price of pure cultured conventional fish per 667m ~ 2 surface water is generally around 500 yuan. In order to fully tap the potential of water, reduce farming costs, reduce investment risks and improve product quality and pond farming benefits. I believe that the proper placement of some of the special species in the pond, without affecting the production of conventional fish at the same time, every 667m ~ 2 surface can be
