The researchers studied the fish community in Jiaozhou Bay during autumn and winter. They found that there were 50 different fish species, with varying amounts of fish caught each month. The dominant species changed with the seasons, from warm-temperate migratory species to cold-temperate resident ones. The diversity of fish species remained consistent between autumn and winter. Overall, the fish community could be grouped into autumn and winter assemblages, but there were no significant differences in community structure between the two seasons.
