蛤蟆通水库浮游生物的研究

STUDIES ON THE PLANKTON OF HAMATONG RESERVOIR

１９９１～１９９４年对蛤蟆通水库浮游生物进行了调查。浮游植物８门９６种属，浮游动物８６种属；浮游植物生物量年平均为４．６２４ｍｇ／ｌ，浮游动物生物量年平均为２．６３１ｍｇ／ｌ；浮游植物生物量中以硅藻为主，占４８．３０％，浮游动物生物量中轮虫类最高，占６７．０％；鱼类生长期（５～９月）浮游植物生物量为１０．９９２ｍｇ／ｌ，浮游动物生物量为３．３１５ｍｇ／ｌ；冰封或冰下浮游植物的种类组成、生物量等明显与越冬池冰下浮游植不同。浮游生物可提供的鱼产潜力为５４０．９吨。

This paper embodies the results of investigations on the plankton of Hamaton reservoir during 1991-1994.They may be summarized as follows:1.The species of phytoplankton was 96,species of zooplankton was 86.2.The average biomass of phytoplankton was 4.62mg/l,average biomass of zooplankton was 2.631mg/l.3. The biomass of Bacillariuphyla was 48.3% in biomass of phyloplanklon,the biomass of Rotifera was 67.0%in biomass of zooplankton.4.The biomass of phytoplankton was 10.992% mg/l,and biomass of zooplankton was 3.351mg/l during 5-9 month.5.The species and biomass of phytoplankton was different in the reservoir and overwintering fishponds.6. The fishery potentiality of plankton was 540.9T in Hamatong reservoir.
