Investigation and analysis of the community structure characteristics of zooplankton in Zibo

Abstract

In order to understand the water ecological environment and the characteristics of plankton community structure in the Zibo area, a survey and study of plankton was conducted in the Zibo Basin in the autumn of 2022. By collecting zooplankton from nine major rivers within the country, a total of 122 species were collected from four phyla. Among them, rotifers are the most abundant, with a total of 77 species, accounting for 63%; Next are protozoa, with a total of 24 species, accounting for 20%; There are a total of 11 species of cladocerans, accounting for 9%; There are 10 species of copepods, accounting for 8%. The average density is 229.58/L, and the average biomass of zooplankton is 2.1997mg/L. The Shannon Wiener diversity index for zooplankton is 3.35. The survey results show that the water quality in the Zibo section is generally in a light pollution state. It is recommended to take further effective measures to strengthen the environmental governance around the watershed, reduce the discharge of domestic sewage, and reduce human activity interference.
