According to the survey results from July 2000 to July 2002, there are 3 species of planktonic branches in Zhelin Bay of Guangdong Province, belonging to 2 genera and 3 genera, of which, Penilia avirostris, Which accounted for 9.08% of the total number of zooplankton species and 91.84% of the total number of cladocera species in the dominant species of the year. The densely planted cladoceran are located in the Huanggang River estuary and the outlying bay waters, There was a significant negative correlation between the quantity and salinity.The seasonal variation of the planktonic branches was extremely significant, showing the basic patterns of summer, autumn, winter and spring, with a significant positive correlation with the water temperature
