| 摘 要： | 根据广东省惠阳县１９８５－１９８６年网箱养殖的生产统计数据，拟合了真鲷的生产函数。该生产函数为二次模型，解释变量包括放养密度、鱼种规格、养殖期、饲料系数及其平方项和叉乘项。模型的决定系数为８２．８％。根据生产函数计算了在不同水平的养殖期、鱼种规格、鱼种价格及成鱼的市场人格等条件下获得最大经济效益的放养密度。

| Abstract: | A production function for cage culture of Pagrosomus major was estimated by data from a survey of producers in Huiyang county, Guangdong province during 1985-1986. Explanatory variables in the quadratic model included stocking density, fingerling size, length of growing season, feed coefficient, squared and cross product terms. Model R 2 was 82.8%. Profit maximizing stocking densities were calculated for varying levels of growing season duration, fingerling size, fingerling price and adult fish price. |
