Taxonomic diversity of fish community in the waters surrounding the Taishan Islands of Fujian Province

According to the data collected from four seasonal trawling surveys between 2012 and 2013 in the waters surrounding the Taishan Islands, we made a list of fish species in this area and calculated its taxonomic diversity by PRIMER 5.0. We identified 208 fish species including 2 classes, 20 orders, 81 families and 150 genera in the waters around Taishan Islands, with Perciformes being the major order. According to the survey data from 2012 to 2013, 77 fish species including 2 classes, 11 orders, 40 families and 63 genera were identified. The average taxonomic distinctness (△⁺) and variation in taxonomic distinctness (∧⁺) of fish species listed in that area were 63.14 and 378.4, respectively. The taxonomic diversity (△) and taxonomic distinctness (△^*) were higher in autumn and spring than in summer and winter. It is concluded that the species in spring was more than that in summer and autumn, and was the least in winter. Water temperature and food were the main factors which affect fish species composition.
