| 摘 要： | 用矩阵描述了放养和捕捞的一般数量关系，根据这个关系，用过去数年的放养数据和渔获物的年龄组成数据，可以求得回捕率；将１９９８年秋和１９９９年春测定的该水库放养鲢、鳙的回捕率代入该矩阵中，得出其放养－捕捞的数量方程。该方程可以作为指导水库制订放养和捕捞计划的依据。

| Abstract: | One year old silver carp \%Hypophthalmichthys molitrix\% and bighead carp \%Aristichthys nobilis\% juveniles were stocked into lakes or reservoirs each year while some of the grow up ones stocked previously were caught to be production of a fishery farm. The paper describes a common quantity relationship between stocking amount and caught back amount using a matrix in Dahuofang Reservoir. Using the data of stocked and captive age structure of the autumn of 1998 and the spring of 1999 by the matrix, the capture back rates (CBR) can be figured out. Applying the CBR to the matrix, the paper gets the equation of stocked amount and caught back amount of the fish populations in the reservoir which could be used as a rule guideline to stocking and catching by the administrator of the farm. |
