Abstract:

To reveal the taxonomic diversity of crustaceans in Yellow Sea and Bohai Sea, a species list of crustaceans (Malacostraca: Decapoda and Stomatopoda) was obtained by the Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, using survey data collected by bottom trawling from 2010 to 2015. A total species list of crustaceans was also obtained by combining the species list above with historical literature. Based on the above two lists, the inclusion index at taxonomic level (TINCLi), average taxonomic distinctness index (Δ+) and variation in taxonomic distinctness index (Λ+) were computed. A total of 93 species of crustaceans, belonging to 2 orders, 39 families, and 66 genera, were recorded from 2010 to 2015. Among these, 10 species were newly recorded. Penaeidae, Hippolytidae, Palaemonidae, Portunidae and Varunidae were among the top 5 families, accounting for 38.71% of the total species. TINCLi were 1.41 species/genus and 2.38 species/family, respectively. Δ+ and Λ+ were 50.25 and 35.20, respectively. According to the total species list, a total of 228 species of crustaceans were recorded, belonging to 2 orders, 53 families, and 123 genera. Hippolytidae, Pinnotheridae, Penaeidae, Varunidae and Alpheidae were among the top 5 families, accounting for 30.70% of the total species. TINCLi were 1.85 species/genus and 4.30 species/family. Δ+ and Λ+ were 50.18 and 30.87, respectively. The relative richness index (Rr) of Penaeidae (100) was the highest, followed by Portunidae (71.43) and Palaemonidae (62.50). The relative richness index (Rr) of Pinnotheridae (6.25) was the lowest. The average taxonomic distinctness index (Δ+) of crustaceans was less than that of fish in Yellow Sea and Bohai Sea (P < 0.05). The value of Δ+ calculated by recent surveys was higher than the theoretical value and was within the 95% confidence intervals. This result shows that crustacean species in Yellow Sea and Bohai Sea were being intermediately disturbed.
