Analysis of Water Quality and Community Composition of Plankton from Cultivating Ponds of Chalcalburnus chalcoides Aralensis
摘要
Abstract
Species composition and population density of plankton from cultivating ponds of Chalcalburnus chalcoides Aralensis,and water chemical parameters were studied from June to September of 2009.The results showed that the concentration of salinity was 0.19％,ALK:9.72 mmol/L,DK:9.99 mmol/L and pH 9.01.The concentration of COD was 14.99 mg/L.The total nitrugen was 1.13 mg/L and the total phosphate was 0.26 mg/L.The water tape was C1Mg.The water quality was both of high pH and high ALK.Ten phytoplankton species from 4 phyluna were found,in which Cyanophyta were 40.07 ％ and Microcystis aeruginosa was found to be dominant,at the same time,both 2 species from Chlorophyt and Bacillariophyta were found,about 33.5％ and 22.5％,respectively.Closterium sp.was found to be dominant in Chlorophyt community.Moreover,there were 2 species of other phylum including Trachelomonas and Cryptomonas,accounting for 4.35 ％.The abundance of phytoplankton was found to range from 631.2 × 104-1 091.4 × 104 ind/L,and biomass range from 26.124-41.325 mg/L.There were 10 species of zooplankton,in which 3 genuses belonged to Rotipera,and the proportion was 33.3％.The three species of clodocera were 22.99％,only 1 species of protoza was about 16.27％,and 2 species from Copepoda were found to be 45.55％.The abundance of zooplankton was found to range from 175-264 ind/L,and biomass range from 13.15-19.44 mg/L.The abundance of phytoplankton in June was larger than that in other months,and decreased in July,the abundance was at the lowest levels in September.There was no significant difference for the community changes of Zooplankton from mid July to mid September.The data of water chemical parameters and the dynamics of phytoplankton showed that the cultivating pond was eutrophication.The biomass abundance was of high nutrition and high yield.关键词
