利用黑白瓶测氧法对水封水库的浮游植物的初级生产力进行测定,并对水封水库的鲢、鳙产量进行测算。结果表明:水库浮游植物水柱平均日生产量为14.5g O~2/m~2·d;初级生产力评估水丰水库鲢鳙鱼产力达17284333.5kg。水丰水库水体富营养化水平高,可根据水库水质状况科学合理制定发展渔业发展规划、科学指导渔业生产,对实现水库渔业健康可持续发展意义重大。
The primary productivity of phytoplankton in water sealed reservoirs was measured by black and white bottle oxygen test, and the production of silver carp and bighead carp in water sealed reservoirs were calculated. The results showed that the average daily production of phytoplankton water column was 14.5g O ~ 2 / m ~ 2 · d, and the productivity of silver carp and bighead carp in the assessment of primary productivity reached 17284333.5kg. The water eutrophication level of Shuifeng Reservoir is high. According to the status of reservoir water quality, it is scientific and reasonable to make plans for the development of fisheries development. Scientifically guiding the fishery production is of great significance to realize the healthy and sustainable development of reservoir fisheries.
