| 摘 要： | 于１９９８年７￣９月在山东海阳养虾场运用陆基围隔实验生态学方法,研究了对虾与罗非鱼在五种放养密度下浮游生物群落的变动情况。结果表明;可能浮游动物的摄食对浮游植物产生影响,二者数量的消长在大多数围隔都呈负相关;纤毛虫的数量与浮游植物的总生物量呈负相关;随着养殖密度的增加,浮游植物生物量减少,而浮游动物却有所增加,前者的优势类群由硅藻变为甲藻、蓝藻和隐藻。后者的在组成中镖水蚤数量减少而剑水蚤、无节幼体、轮虫和原生动物等小型种类有所增加;纤毛虫在高密度围隔中大量繁殖,说明水质已逐渐恶化。

| Abstract: | This paper deals w ith the variations of plankton communities in enclosures in which shrimp and tilapia
were stocked in f ive densit ies: 2. 8 ind..m- 2, 5. 6 ind..m- 2, 8. 4 ind..m- 2, 11. 2 ind..m- 2, 14. 0 ind..m- 2.
The study was conducted in a shrimp farming pond from July to September, 1998 w ith the enclosure -
experimental method. The following result s were obtained: ( 1) Because zooplankton feed on phytoplankton,
their quantities were in negative correlation in the most enclosures; ( 2) The total biomass of ciliates showed no
signif icant correlation with the biomass of zooplankton, but showed negative correlat ion with the biomass of
phytoplankton; ( 3) The biomass of phytoplankton was decreased and the saprophilous forms of Pyrrophyta,
Crytophyta, Cyanophyta instead of Bacillariophyta and Chrysophyta became dominant group in the enclosures
w ith higher shrimp, but zooplankton.. s biomass was increased, supported by the smaller ones; ( 4) Ciliates breed
abundantly in higher stocking enclosure, which showed the quality of water becoming bad. |
