扁担塘、后湖大型底栖动物代表水丝蚓、铜锈环棱螺对红鲤的平均饵料系数(湿重)分别为6.2、31.3。据此估算的理论渔业增产潜力分别是:扁担塘底栖动物的渔产潜力为4 259.83 kg/hm2,后湖底栖动物的渔产潜力为4 825.78 kg/hm2。后湖底栖动物的生产量和渔产潜力均比扁担塘的要高。
Biantangtang, Houhu macrobenthos on behalf of water wireworm, copper ring Borlotti on red carp average bait coefficient (wet weight) were 6.2,31.3. Based on this, the potential productivity gains of theoretical fisheries are as follows: the potential productivity of benthic fauna in Biantang reservoir is 4 259.83 kg / hm2, and the potential productivity of benthic fauna in the back lake is 4 825.78 kg / hm2. The production and fisheries potential of benthic fauna after lake are higher than that of the pond.
