南北湖渔业资源现状及开发途径的探讨

作者于１９９５年对位于杭州湾北岸海盐县境内的南北湖进行了周年浮生物种群组成调查及生物量季节变化的测定，由此估算出该湖食浮游生物及腐屑的鱼类增产潜力。鉴于南北湖是著名风景湖泊，在渔业上不宜采取投饵施肥方式增加鱼是疾病，但针对良料资源状况选择适宜品种，有节制地增殖放养某些经济鱼虾，不仅能

Present Status of Fisheries Resources in Nanbei Lake and Its Exploitation

In 1995, the authors conducted year round ( in four seasous ) investigation on plankton population composition and measured the biomass seasonal variations of Nanbei Lake, which is located on the north coast of Hangzhou Bay and within the jurisdiction of Haiyan County. And the potential of fish production was thus estimated, based on the results of the investigation. It is obviously unreasonable to increase the fish and shrimp production of the lake through feeding and fertilizing, as Nanbei Lake is a famous scenic spot. However, on basis of the present status of natural food resources in the lake, selection and sticking some commercial fish and shrimp species to a certain extent will not only bring into play some fishery benefits, but also be favourable for water quality control and for prevention of eutrophication of the water body.
