| 摘 要： | On the basis of the data of zooplankton collected from 20 stations in Xiangshan Bay in January, April, July and October, 2000, the abundance and biomass of zooplankton and the relations to mariculture environment are analyzed in this paper. The results show that there were significant seasonal variations in zooplankton biomass and abundance in the surveyed area. The biomass peaked in July, followed by April and October, and the lowest biomass appeared in January. The highest abundance was observed in April, followed by July, October and January. There were similar horizontal distribution patterns for the biomass and abundance of zooplankton. They both decreased from bay head to bay mouth in January and April, but increased from bay head to bay mouth during October. Biomass and abundance were distributed evenly in the surveyed area in July. The zooplankton biomass and abundance in cage culture area were apparently lower than those in non-culture area indicating that cage culture has negative effects on zooplankton in surrounding waters.

| Abstract: | On the basis of the data of zooplankton collected from 20 stations in Xiangshan Bay in January, April, July and October, 2000, the abundance and biomass of zooplankton and the relations to manculture environment are analyzed in this paper. The results show that there were significant seasonal variations in zooplankton biomass and abundance in the surveyed area. The biomass peaked in July, followed by April and October, and the lowest biomass appeared in January. The highest abundance was observed in April, followed by July, October and January. There were similar horizontal distribution patterns for the biomass and abundance of zooplankton. They both decreased from bay head to bay mouth in January and April, but increased from bay head to bay mouth during October. Biomass and abundance were distributed evenly in the surveyed area in July. The zooplankton biomass and abundance in cage culture area were apparently lower than those in non-culture area indicating that cage culture has negative effects on zooplankton in surrounding waters. |
