通过各种饲养技术不同鱼产量的经济核算结果的比较分析,证明草鱼与白链为主的单季饲养技术是经济效益较高、生产可行性较好的优势技术,应作为池塘成鱼饲养的发展重点。在一定范围内亩净利润与亩净产呈紧密正相关,为了提高池塘成鱼饲养的经济效益,生产上应推行亩净产300-1000公斤的高产技术。增加饲料地面积比是提高新建商品鱼基地投资效益的好办法。在城郊应试行“周年鱼”的饲养方法。
Through the comparison and analysis of the economic accounting results of different fish production by various feeding techniques, it is proved that the single-season feeding technique based on grass carp and white chain is the superior technology with higher economic benefit and better production feasibility and should be used as the pond fish feeding Development focus. In a certain range, the net profit of mu is closely related to the net production of mu. In order to improve the economic benefits of feeding the pond into fish, the production should promote the high-yielding technology with a net production of 300-1000 kg per mu. Increasing the feed area ratio is a good way to increase the investment returns of a new commercial fish base. In the suburbs should try out the “annual fish” feeding method.
