内陆水域鱼类放养捕捞模型及应用

用矩阵形式描述了放养捕捞的数学模型，对主要变量－回捕率的估测方法（渔获物年龄组成法、历史放养捕捞数据法和标志回捕法）进行了说明。用渔获物年龄组成和历史放养捕捞数据法，估算了大伙房水库鲢、鳙的牧养回捕率，还对目前牧养群体资源研究中参数求解问题提出了相应的见解。

The model of stocking and catching for fish culture in inland water and its application

The mathematic model is expressed by using matrix, in which the main variable-recapture rate is assessed using the methods of age population analysis, history recorded data analysis of stock and tagged capture analysis. The former two methods are applied in analyzing the stocks of silver carp and bighead carp in Dahuofang Reservoir (Fushun, Liaoning Province), and some important issues in evaluating stocking amount and some comments on the methods presently employed in this area were discussed.
