Thirty years of change of fish communities in South China Sea
Daya Bay is a representative semi-enclosed bay in the South China Sea, with a variety of ecosystems including mangroves, coral reefs, shelves, estuaries, salt marshes and quagmires. It is an important spawning ground, feeding ground and germplasm bank of main economic fish in the South China Sea. However, with the combined effects of multiple stressors such as human activities and climate change, especially environmental pollution, overfishing, and habitat fragmentation, fish resources in Daya Bay are in a state of decline. Long-term variation in fish community structure in this Bay remains uncertain.
