摘要
本文运用生物监测法,研完了密云水库的网箱养鱼对水质的影响,发现水体浮游生物月平均生物量为3.0310mg/L,底栖动物月平均为2 768.3条/m^2(3.323 5g/m^2),总磷月平均为0.058gm/L,说明网箱养鱼区及其周围水域,总体呈现“中-富营养化”与“中-严重污染”。
This paper presents a result of inquiry into the effect of proposed net tank fish breed on its water quality with biological monitor method. It is found that the average biomass of the plankton of water body is 3.0310 mg/L; the average number and biomass of zoobenthos is 2768.3 d/3.3235g/m^2; and the total phosphorus is about 0.058 mg/L. It shows that in the central area of net tank fish breed as well as in the area around watershed, the overall of reservoir presents a level of 'middle-eutrophic water type' and 'middle-serious polluted zone'.
