| 摘 要： | 采用陆基试验围隔的方法研究了施肥后河蟹育苗池中浮游生物的变化情况。施肥后,各试验围隔前期浮游植物生物量随着时间变化明显,迅速达到高峰期。而后,由于轮虫的大量繁殖,使浮游植物生物量又迅速回落;在种群组成上,前期小球藻一直占优势,后期大型藻类大量出现后,小球藻生物量不大;围隔水体中浮游动物主要以轮虫为主,其生物量随着时间的变化明显,但空间分布不明显。轮虫的摄食对浮游植物生物量有影响,二者相互消长,但由于后期大型浮游植物的影响,并没有呈现出典型的负相关关系;桡足类对早期蟹苗危害较大,但后期可成为蟹苗的摄食对象。 |

| Abstract: | The change in plankton biomass was studied in an enclosure affer fertilization for Chinese mitten crab(Eriocheir sinensis) breeding.The phytoplankton biomass changed drastically and reached to peak rapidly,then dropped down again in early stage.Chlorella as a dominant species increased in number in early stage while the large algae increased in quantities in later stage.Rotifer increased to be a dominant species in zooplankton in the water of the ponds.There was a positive correlation between the zooplankton biomass and rearing time,but there was not significant correlation between the zooplanton biomass and rearing space.The mount of phytoplankton was effected by the feeding of rotifer.Copepoda was harmful to crab larva in early stage,but became natural food for the crab larvae in later stage. |
| Keywords: | Eriocheir sinensis enclosure phytoplankton zooplankton regular variation |
