摘要:
澄湖隶属苏州市,面积为45km2,平均水深1.83m,湖内水生维管束植物甚少,主要放养的鱼类有鲢、鳙等。浮游藻类计7门94属,主要的优势种有铜色微胞藻、颗粒直链藻、四尾栅列藻等。数量和生物量的季节变化均以春季最高、秋季最低。但前者以夏季次之,而后者以冬季为次之。最后就澄湖浮游藻类秋季低产的原因及对该湖鱼产潜力进行了讨论。

Abstract:
Chenghu Lake belongs to the city of Suzhou with an area of 45 km2 and an average depth of 1.83m .There are very few aquatic plants in Chenghu Lake and the principal cultural fishes are silver carp and big head carp.All of the samples were collected from the stations in Chenghu Lake, 94 genera of phytoplankton were identified. The dominant species are Microcystis aeruginosa, Melosira granulata, Scenedesmus quadricauda. The total number of the phytoplankton varies with the seasons. There are 20365110 cell/L, 18655580 cell/L, 1759910 cell/L, 12246920 cell/L in spring, summer, autumn and winter separately. The biomass of the phytoplankton varies with the seasons too. There are 13.255mg/L, 3.932mg/L, 1.074mg/L and 10.807mg/L in spring, summer, autumn and winter separately. The potential development of fishery in Chenghu Lake was discussed.
