湖鲫、鲤鱼的增产潜力及渔业生态管理研究

自１９９１年以来，对氵鬲湖鲫、鲤鱼的种群结构、生态环境等进行了较全面的调查研究，提出了在保持草型湖泊生态系统良性循环基础上，合理地利用氵鬲湖天然饵料资源进行渔业生态管理，使可更新资源尽可能多地转化为鲫、鲤商品鱼的建议，以充分提高鲫、鲤产值效益。文中有关入湖鱼种死亡过程的双峰曲线，尚未见诸报道。

STUDY ON THE POTENTIAL PRODUCTIVITY OF CRUCIAN CARP AND COMMON CARP IN GE LAKE,AND ON THE ECOLOGICAL MANAGEMENT OF ITS FISHERY

A comprehensive study has been carried out by the authors since 1991 on the population structure of the crucian carp and common carp in Ge Lake, and on the ecological environment of the lake. On the basis of keeping ecosystem of the plant filled lake cycling well, the idea of administrating the lake fishery ecologically by making use of the idle natural resourses of Ge Lake, so as to change the renewable resourses into commodity crucian carp and common carp and to enhance the value of benefit is proposed. The double peaked curve describing the death of fingerling after being transferred into the lake, is reported for the first time.
