Investigation and Diversity Study of Aquatic Biological Resources in a Reservoirs in Anji County
This study seeks to conduct a comprehensive survey of the current status of aquatic biological resources in one of Anji Reservoirs,including monitoring fish and phytoplankton within the area,and analyzes their species composition,community structure stability,and biodiversity.The survey revealed the existence of 83 fish species,classified into 3 orders and 6 families,predominantly belonging to Cypriniformes.Planktonic plants are found which belong to 7 phyla and 34 species,with an average density and biomass of 32332.1 cell/L and 474.4 mg/L,re-spectively.Phytoplankton in the studied area was dominantly composed of Bacillariophyta and Chlorophyta,and the diversity at each site is rich.The zooplankton belonged to 4 classes and 18 species,with an average density and biomass of 17.4 ind./L and 190.6 pg/L,respectively.They are mainly rotifers and copepods,and are relatively abundant in the reservoir area and upstream.The results indicate that the aquatic biodiversity of the reservoir is rich and stable,but the regional differences are large.Long-term aquatic ecological monitoring is recommended to strengthen the protection of its biodiversity and maintain a favorable habitat.
