Community structure of benthic molluscs shaped by environmental and ecological variables in the coastal waters of Changle, Fujian Province, China
To understand the community structure of benthic molluscs and their relationship under varying environmental and ecological conditions, monthly samplings in April−September 2019 were conducted at 27 stations in an approximate sea area of 20,600 ha (Changle District, Fujian Province, China).

| description | To understand the community structure of benthic molluscs and their relationship under varying environmental and ecological conditions, monthly samplings in April−September 2019 were conducted at 27 stations in an approximate sea area of 20,600 ha (Changle District, Fujian Province, China). Forty-five species were identified, most as food; six dominant species, all bivalves and commercially important, were determined by the index of relative importance > 500. The average abundance and biomass were 308.32 × 103 ± 1,156.24 × 103 ind./km2 and 1,423.71 ± 2,272.37 kg/km2, respectively. Three spatial community groups were identified, named Min River Estuary, Nearshore, and Offshore, with significant differences in species composition and abundance (ANOSIM, p < 0.01). Results of the canonical correlation analysis indicated that the community structure of benthic molluscs was significantly related to water depth, pH, salinity, temperature, phytoplankton abundance and zooplankton abundance (p < 0.1). As the important habitat for benthic molluscs, long-term monitoring in the coastal waters of Changle is needed for sustainable harvest. |
