南京固城湖的水生生物资源及其合理利用

RESOURCE OF AQUATIC ORGANISMS IN CUCHENG LAKE OF NQNJING AND ITS RATIONAL UTILIZATION.

作者介绍了固城湖1987年6月—1988年7月调查所获各种水生生物的种类、数量和生物量等,并估算了该湖养殖鱼类的鱼产潜力及放养量。如全湖放足18×10~5尾,并满足各种鱼类的生长条件,除现有750t鱼产量外,还可增产850t鱼。本文为科学管理固城湖提供了一系列实用数据,同时还对该湖的资源合理利用和保护提出了可行性建议。

The variety, quantity and biomass of various aquatic organisms in Gucheng lake of Nanuing had been investigated from June 1987 to July 1988. The fish production and stocking mass of rearing fish in the lake have been approximately calculated. It is concluded that if the quantity of fish increases to the maximum allowance (1.8 million fish) of the lake, fish production can be increased from present 750 tonnes to 1600 tonnes. In addition, this study can also provide a series of useful data for scientific managemant of Gucheng lake. The feasible suggestions about the ra tional utilization and protection of the resources in the lake are also proposed.
