本文通过对 1985年—1989年滆湖水质营养状态及此期间网围养殖规模和投饵情况调查结果的评价,分析了网围养殖对滆湖水体营养状态的影响。研究结果是:目前滆湖水质处于中营养(前期)状态。网围养殖后,加快了水体富营养化进程,但速度较同类浅水型湖泊缓慢。并根据对研究结果的分析提出了应采取的对策。
In this paper, we evaluated the nutritional status of Bahu Lake in 1985-1989 and the results of surveys on the scale and feeding situation of net-cage farming during this period. We analyzed the effects of net-farming on the nutritional status of Bahu Lake. The result is: At present, the lake water quality is in medium nutrition (early stage). Mesh farming, accelerated the process of eutrophication of water, but slower than the similar shallow water lakes. According to the analysis of the research results, the countermeasures should be put forward.
