Title: Temporal and Spatial Distribution of Abundance and Biomass of Zooplankton in the Nanji Islands Marine Nature Reserve
Abstract: On the basis of the data of zooplankton collected in the Nanji Islands Marine Nature Reserve sea area in May, August, November of 2004 and February of 2005, this paper analyzed the temporal and spatial distribution of zooplankton abundance and biomass, its relations to environmental factors, the comparison between 2004 and 1990, and the characteristics of ecotypes abundance composition in four seasons. The results showed that there were significant seasonal variation of zooplankton abundance and biomass in the surveyed sea area. The highest abundance was observed in August, followed by November, May and February. The biomass peaked in May, followed by August, November and February. The abundance was very positively correlated to the biomass. The abundance and biomass of zooplankton was positively correlated to the temperature, negatively correlated to IN and PO4-P, and not correlated to the abundance of phytoplankton and the content of chlorophyll a. The abundance and biomass of zooplankton in Spring of 2004 was lower than that of 1990. The composition of ecotypes abundance showed certain seasonal variation.
