This study explores the progress and challenges of species identification of wild fish in Hainan Island and the South China Sea region. Hainan Island and the South China Sea region are rich in Marine and freshwater habitats with a wide variety of fish species. Traditional morphological methods have limitations when distinguishing different fish species. By using technologies such as DNA barcoding, environmental DNA (eDNA), and high-throughput sequencing, the accuracy and efficiency of fish species identification will be enhanced, making it easier to discover hidden new species, monitor new species, and invasive fish communities. New technologies such as vision artificial intelligence image recognition, multi-modal data fusion, and regional fish database construction have developed a more intelligent and standardized species identification system. The combination of technological research and practice has made Hainan Island and the South China Sea region a popular area for the development and application of fish species identification technology.
