Abstract: In order to reveal the taxonomic diversity of common fishes in Zhoushan coastal waters and to protect and utilize fisheries resources more reasonably, Nelson’s classification system was used to evaluate the taxonomic diversity at different taxonomic levels based on the investigation of fish resources and research data in Zhoushan coastal waters, including the inclusion index at taxonomic level (TINCLi)， taxonomic diversity (Δ+ and Λ+), genus-family diversity index (G-F index) and relative abundances index (Rr). It was found that 154 species involving in 16 orders, 63 families and 118 genera, with absolute dominant species in Perciformes. The inclusion index at the taxonomic level showed that the average values of fish constituent in the order were 3.88 families, 7.38 genera and 9.63 species, the average values were 1.90 genera and 2.48 species in family, and the average values of genus were 1.31 species. There was higher TINCLi value at the order and family levels than that in Tangshan Bay and Dongshan Bay, but lower than that in Daya Bay and East China Sea continental shelf, with the average of 60.0 and of 340.8, lower taxonomic distinctness index Δ+ than that in the four sea areas above, and higher variation in taxonomic distinctness Λ+ than that in the four sea areas. The G-F index analysis showed that G index was 4.67, F index was 23.44 and G-F index was 0.80, higher than in the other five bays in Zhejiang coastal area. The relative abundance in Perciformes was shown to be the maximum at the order level (462.5), and that in Gobiidae was the maximum at the family level (26.98). The findings indicated that the composition of common fish species in Zhoushan coastal waters was characterized by relatively concentrated, the relatively close genetic relationship, low classification uniformity, and the high diversity at the level of family and genus.
