草鱼池塘集约化养殖模式研究与分析

Researches and Analysis on Intensive Aquaculture Model on Grass Carp in Pond

本文对池塘主养草鱼不同搭配种类和比例的放养模式进行初步探讨,在相同饲养管理条件下,投喂相同的草鱼配合饲料。试验结果为1#塘生产草鱼9754kg,鲤鱼1500kg,异育银鲫492.5kg,鲢鱼、鳙鱼共1383kg,平均每666.7m^2鱼产量1312.95kg,利润4786.40元,饲料系数1.70,投入产出比为1：1.70。2#塘生产草鱼4482.2kg,鳙鱼1760kg,平均每666.7m^2鱼产量624.22kg,利润-55.02元,饲料系数1.24,投入产出比为1：0.98。试验表明：合理的养殖模式是池塘主养草鱼成功和获得较高经济效益的关键。

The best aquaculture model of grass carp was studied in two ponds by different stocking species and ratio. The two ponds with the same management and the same formulated feed, the result showed that productions of grass carp in 1 # pond 9754 kg, comman carp 1500 kg, silver crudan carp 492.5 kg, silver carp and big head carp 1383 kg. the production 1312.95 kg, the profit 4786. 40 yuan in 666.7 m^2,The ratio of profit 1 ： 1.70,The feed coefficient 1.70, respaetively. Yields of 2 # pond was grass carp 4482.2 kg, big head carp 1760.0 kg, the average production 624.22 kg. the average profit -55.0 yuan in 666.7 m^2, the ratio of profit 1 ： 0.98, the feed coefficient 1.24, respectively. The result indicated that suitable breeding pattern was the key of success and high profit on major fanning of grass carp in pond.
