摘要
１９９１年和１９９２年的６月，对女山湖底栖动物进行两次现场调查，共采集到底栖动物３８种；推算现存量，１９９１年为１１６２７ｔ，１９９２年为１１７４７ｔ；与１０年前的同期调查资料相比，该湖的底栖动物密度和生物量均显著降低。还分析了资源下降原因，提出了利用和保护该湖底栖动物资源的对策。
Zoobenthos in the Nushan Lake were investigated in June,1991～1992,and the results could be summarized as follows:a.38 species of zoobenthos were collected.b.their standing-crops counted 11 627 t in 1991 and 11 747 t in 1992,not only their density,but also their biomass showed a significantly decreased tendency in comparison with the density and biomass before 10 years.c.It is discussed how to preserve and use the zoobenthos for fishery.
