一、自养鱼种养鱼成本主要由鱼种成本、饵肥成本、折旧、增氧、排灌、药物成本和劳动报酬等四项构成,其中鱼种是养鱼成本的主要成本之一。养鱼者可以利用部分浅水池或小塘堰,小沟等自养鱼种,既解决了鱼种来源,又解决了数量的不够,从而降低了成本。二、科学搭配,发展生态渔业由于养殖鱼类的栖息习性和食性不同,混养能充分利用水层,相应地增加了单位面积的放养量,更加充分利用了各种饵料来源,同时还可在养鱼水体
First, the cost of self-raising fish species of fish farming mainly by the cost of fish species, bait cost, depreciation, oxygen, irrigation and drainage, drug costs and labor compensation of the four components, of which fish species is one of the major costs of fish farming costs. Fish farmers can use part of the shallow pool or small pond weir, small ditch and other self-feeding species, both to solve the source of fish species, but also solved the problem of insufficient quantity, thus reducing the cost. Second, scientific matching, the development of ecological fisheries Due to the habitat and feeding habits of farmed fish different, polyculture can make full use of the water layer, correspondingly increased the stocking per unit area, more fully utilize all kinds of food sources, but also in Fish water body
