Abstract  

We surveyed and analyzed on the community structure of Phytoplankton in the white shrimp culture Ponds in Xuwang non-polluted culture base, Zhoushan, Zhejiang between April 30th, 2006 and August 31st, 2006. The results showed that total of 5 phyla 16 species were identified, including 4 Cyanophyta species, 5 Chlorophyta species, 5 Bacillariophyta species, 1 Euglenophyta species and 1 Pyrrophyta species. Cyanophyta mainly includes Merismopedia tenuissima., Phorimidium sp., Spirulina sp., et al; common Chlorophyta includes Chlorella sp., Chlamydomonas sp.,et al; common Bacillariophyta includes Navicula sp., Synedra acus. In the early culture period, total of 3 phyla 9 species were identified, without Cyanophyta and Euglenophyta species, Their average valuedensity was 0.8×107 cells·L-1, biodiversity index was 0.445. In late culture period, 4 phyla 12 species without Pyrrophyta species were identified,the average valuedensity was 1.5×107 cells·L-1, biodiversity index was 0.375. The species numbers, biomass and biodiversity index were high in early culture period and low in lateculture period.
