Abstract: To elucidate the composition and structure of macrobenthic communities and their inter-annual variations in the Yellow Sea and the Bohai Sea, Agassiz trawling was conducted in May 2010 and June 2013. The composition and structure of macrobenthic communities in the Yellow Sea and the Bohai Sea were revealed and analyzed, including species composition, dominant species, abundance, biomass and community structure, and AMBI and m-AMBI were also used to assess the ecological status. The results showed as follows: A total of 131 macrobenthic species were identified, with Mollusca (51 species) and Crustacea (42 species) as the dominant groups in these waters, followed by fishes, polychaetes and echinoderms. There were four species whose dominance were over 0.02, including Alpheus japonicus, Crangon hakodatei, Stegophiura sladeni and Acila mirabilis, of which Stegophiura sladeni had the highest abundance and dominance. The results of benthic biological indices (AMBI and m-AMBI) showed that the benthic ecological status in the Yellow Sea and Bohai Sea was relatively stable, however, the benthic ecological quality had degraded during the last few decades when compared with historical data and published researches.

Key words: macrobenthos, the Yellow Sea and the Bohai Sea, community composition and structure, inter-annual variation
