Abstract：Based on the bottom trawl survey data of nekton in the Bohai Sea in May (spring) and August (summer) of 2015 and January (winter) of 2016, the seasonal variations in the community structure of nekton were analyzed. The results showed that 96 species of nekton were captured in the survey, including 55 species of fish, 37 species of crustaceans, and 4 species of Cephalopods. There were 2 to 5 dominant species [index of relative importance (IRI)>500] in the survey. The dominant species were Oratosquilla oratoria, and Crangon affinis in spring, Engraulis japonicus, Oratosquilla oratoria, Chaeturichthys stigmatia, Loligo sp. and Palaemon gravieri in summer, C. affinis, C. stigmatia, P. gravieri, Alpheus japonicus, and Acanthogobius ommaturus in winter. There was the minimum (244 ind./h) relative abundance of nekton was in spring and maximum (11 391 ind./h) in summer. The relative biomass was minimum in spring (1.56 kg/h) and maximum in summer (38.57 kg/h). From spring to winter, the relative abundance and biomass of nekton were increased firstly and then decreased. Margalef species richness index (D) was varied from 3.61 to 4.99, with the maximum in spring and the minimum in winter. Shannon-wiener's diversity index (H') was ranged from 1.83 to 2.40, with the minimum in winter and the maximum in spring. Pielou evenness index (J') was ranged from 0.49 to 0.59, with the minimum in winter and the maximum in spring. Cluster analysis and multidimensional scaling analysis showed that there was inapparent seasonal variation in similarity of community structure among subseas of the Bohai Sea. SIMPER analysis revealed that the seasonal variations in community structure in spring, summer and winter were involved in the seasonal variations of resources of O. oratoria, Loligo sp. and E. japonicus.
