摘要: |
于 1997年 4月 5日至 1998年 9月 1日对山东高青赵店乡渔场 34个盐碱池浮游动物群落演替及其多样性进行了研究,采集了 389个浮游动物定量水样.结果表明,轮虫主要是在夏秋高温季节占主导地位.桡足类在春季和秋末冬初在大部分养鱼池和所有无鱼对照池中占绝对优势.原生动物在养鱼池浮游动物中占相当比重.浮游动物生物量的季节变动一般都有放养早期的春季生物量峰值和盛夏至初秋的生物量高峰,浮游动物多样性指数的季节变动形式与浮游动物生物量的季节变动不尽相同.其季节变动的总趋势是,冬季最低,春季开始上扬,夏季最高,秋季又开始下降,浮游动物多样性指数在浮游动物生物量峰值时多是低谷,而生物量下降时多样性指数又上升.无鱼对照池和新挖池塘的浮游动物多样性指数和生物量均较一般养鱼池塘的高. |

Abstract: |
The seasonal succession and diversity of zooplankton in saline-alkaline ponds from 5th April, 1997 to 1st September, 1998, in Zhaodian Fish Farm, Gaoqing County, Shandong Province, were examined.389 zooplankton samples were collected.Rotifer was dominant in summer and autumn when water temperature was higher.Copepod was predominant in many fish-culture ponds and all control ponds in spring and in late autumn and early winter.The biomass of protozoa in fish-culture ponds was relative higher than control ponds.The zooplankton biomass, in general, peaked in spring, summer and early autumn.The seasonal dynamic pattern of diversity index of zooplankton is not the same as that of biomass of zooplankton.The diversity was lower in winter, increased in spring, reached the highest in summer, and decreased in autumn.The diversity index of zooplankton was low during the peak period of biomass of zooplankton, and increased with the decrease of biomass of zooplankton.The biomass of zooplankton in control ponds and new ponds was greater than that of other fish-culture ponds. |
