| 摘 要： | 根据商品渔获物规格差异，直观地调整鲢（Hypophthalmichthys molitrix）、鳙（Aristichthys nobilis）在湖泊水库中的放养比例，容易忽视鲢、鳙本身生长速度的差异以及捕捞方式和强度对鱼类正常生长的影响。综合考虑这两方面的影响，给出了根据商品渔获行组成判断鲢、鳙放养比例合理与否的方法。并在大伙房水库进行了应用。结果表明：大焦房水库目前鲢放养效果不佳，主要原因是捕捞方式不合理造成的，同时应该增加鳙的放养比例。

| Abstract: | It is a common method to adjust the stocking ratio of silver carp and bighead carp in lake or reservoir only by comparing their mean body weight or mean body length. But the method is based on omitting the natural difference in growth rate and the effect of fishing method and its intensity on their natural growth. The paper presents a method and standard on scoring the stocking ratio of silver carp and bighead carp. Applied the method to the scoring of the ratio in Dahuofang reservoir, this method shows that the ratio of silver carp to bighead carp is higher than the proper; the fishing method is improper. |
