使用分区围隔,梯度养殖鲢、鳙鱼的研究方法,验证阅海湖鲢、鳙鱼的实际生产潜力,结果表明：阅海湖鲢、鳙鱼产量潜力理论估算为363.83 kg/hm2。围隔试验验证结果表明：在投放140 kg/hm2密度下鲢、鳙鱼生长良好,试验生产力236.5kg/hm2;综合考虑阅海湖实际水环境状况和试验局限,阅海湖平均鲢、鳙鱼产力定为280~300 kg/hm2较合适,低于理论估算量;全湖鲢、鳙最大生潜力为336~360 t;共需投放13 cm以上的鲢、鳙鱼种110万尾,投放比例鲢：鳙=1.4：1。

The actual productivity potentiality of silver carp and bighead carp were verified using the approaches of partitioning enclosure and gradient culture.The result shows that the theoretical evaluation of the potential yield of silver carp and bighead carp in Yuehai Lake was 363.83 kg/hm2 The result of verification of enclosure experiment shows that the growth of silver carp and bighead carp was good under the throw-in density of 140 kg/hm2 and the experimental yield was 236.5 kg/hm2.Considering the comprehensive water environment of Yuehai Lake and the limitation of the experiment,the average yield of silver carp and bighead carp in Yuehai Lake should be decided appropriately as 280~300 kg/hm2 and it is lower than that of theoretical evaluation.The highest potential output of silver carp and bighead carp of the whole lake is 336-360 ton.All together 110 million fingerling of silver carp and bighead carp longer than 13 cm should be thrown in and the throw-in proportion should be that silver carp︰bighead carp =1.4︰1.
