Title: Seasonal variation of meso-and micro-zooplankton community structure in Funing Bay Razor clam( Cultellus scaprum) Reserve of Fujian Province
Abstract: Species composition,quantitative distribution,dominant species,seasonal variation,community structure and influential environmental factors of meso-and micro-zooplankton were studied according to the survey data of Funing Bay Razor clam( Cultellus scaprum) Reserve during the period of autumn 2011,spring 2012 and summer 2012.A total of 45 species of zooplankton belong to 8 taxa as well as 22 groups of pelagic larvae were identified. The species of zooplankton were abundant in summer but fewer in spring. Most species could be divided into two ecotypes which were coastal eurythermal and euryhaline group,offshore semitropical group respectively. There were 18 dominant species during the sampling period,copepod and cirriped pelagic larva dominated the zooplankton community,and moreover,obvious succession existed between different seasons. The average abundance and biomass of zooplankton were 7397. 6 ind / m3 and 143. 3 mg / m3 respectively,the maximum value appeared in spring and the minimum value appeared in autumn. The diversity index was the highest in autumn and the lowest in spring,but the species diversity of zooplankton in the razor clam reserve was not rich. Salinity was the main factor that influenced the species composition,community structure and quantitative distribution of zooplankton.
