Characteristics of Phytoplankton Communities and Water Quality in Waters with Stable Yield of Protosalanx chinensis in Lake Lianhuan
From June 2018 to April 2019,the characteristics of phytoplankton communities and water quality were investigated in waters of Lake Lianhuan with stable yield of Protosalanx chinensis.The results showed that there were 120 species(including undetermined species)of phytoplankton,belonging to 8 Phyla.The means of density and biomass were 372.83×104 ind·L-1 and 2.8043 mg·L-1 respectively.The characteristic of phytoplankton com-munities during the period of P.chinensis growth(open water period),breeding and hatching(frozen period)were different,and the comprehensive analysis showed the community dominated by Chlorophyta.Three diversity indi-ces showed that phytoplankton diversity was higher in the open water period while higher evenness was found in the frozen period.According to the evaluation criteria,the three diversity indices showed that the water quality of watery supporting high and stable yield of P.chinensis ranged from os to α-ms.
