Analysis on community structure and biodiversity of aquatic organism resources in Chaohu Lake of 2018 |
| |
| Abstract: | The aim was to analysis community structure and biodiversity of aquatic resources in Chaohu Lake. The aquatic resources in Chaohu Lake were investigated, species composition, abundance, biomass and dominant species was analyzed. The result showed that a total of 118 species of phytoplankton were identified which belonged to 60 genera, 26 family and 5 phyla; the averaged cell abundance and biomass were 3.1×107 cells/L, 5.7 mg/L, respectively. A total of 140 species of zooplankton were collected. Cladocera, copepoda had 9 species, and rotifer has 24 species. Ciliate had 98 species (included genera). The averaged density and biomass were 1898.9 ind./L, 4.4mg/L, respectively. Zoobenthos had 16 species, and density and biomass were 495.5 ind./m2, 42.04 g/m2. 47 fish species were sampled, belonged to 15 family, 8 order. The dominant fish were Coilia ectenes, Aristichthys nobilis, Carassius auratus, Cyprinus carpio, Culter alburnus, Neosalanx taihuensis et al. the space distribution of plankton and zoobenthos was distinct difference. The study could provide theoretical basis for ecological restoration of Chaohu Lake through synthetical application of food chain regulation technology and wastewater discharge standard improvement. |
