To understand the spatio-temporal variation characteristics of zooplankton communities in the Nanji Islands sea area, three voyage surveys of aquatic organisms and hydrological factors were conducted in November 2022, May 2023, and September 2023, respectively. Laboratory experimental results showed that a total of 93 species of zooplankton were identified, including 20 species of plankton larvae. The 2023.09 voyage recorded the highest species richness (63 species), while the 2022.11 voyage had the lowest (45 species). Among these, 19 dominant species (Y ≥ 0.02) included Sagitta bedoti, Flaccisagitta enflata, Calanus sinicus, Acartia pacifica, and others. The average abundance of zooplankton was 512.84 ind./m³, and the average biomass was 614.82 mg/m³, with significant differences among the voyages. The 2023.09 voyage had the highest abundance and biomass, while the 2022.11 voyage had the lowest. The average values of the Shannon-Wiener diversity index (H'), species evenness index (J'), and richness index (D) for zooplankton were 1.64, 0.55, and 2.57, respectively. Results from Spearman correlation analysis, non-metric Multidimensional Scaling Analysis and Canonical Correspondence Analysis indicated that salinity, temperature, total nitrogen content, nitrate concentration, and phytoplankton abundance were important environmental factors influencing the biomass of dominant zooplankton species in the Nanji Islands sea area.
