Abstract: The phytoplankton community structure and variation in biodiversity were surveyed in a juvenile Chinese mitten handed crab Eriocheir sinensis rearing pond in a Fudao aquaculture professional cooperatives in Chongming County,Shanghai,from July to October of 2013 to evaluate the fishery ecological environment condition in juvenile Chinese mitten handed crab ponds.A total of 77 phytoplankton species within 7 phyla and 37 genera was found,with 16 dominant species.The community was characterized by cyanobacteria-chlorophyta type,with the maximal dominance of cyanobacteria and the maximal species of chlorophyta.The phytoplankton density was ranged from5.02 × 107 to 14.37 × 10~7 cells / L,with an average of 8.88 × 10~7 cells / L,and the phytoplankton biomass from 14.70 to 52.85 mg / L,with an average of 25.33 mg / L.Shannon-Wiener diversity index was 2.73-3.07,Margalef richness index 0.99-1.48 and Pielou evenness index 0.74-0.90.The maximal phytoplankton density and biomass were observed on August 15,without significant difference only between September and October（P 〉 0.05）.There was no significant difference in phytoplankton density and biomass in various juvenile rearing ponds（P 〉 0.05）.The findings indicated that there was complicated community structure of phytoplankton in the juvenile Chinese mitten handed crab rearing ponds in which the water was in the moderate polluted status.
