abstract
From February 2015 to January 2016, we collected fish monthly using a beach seine net at two sandy beaches (B1 and B2), in a muddy sand estuary (MS), and in a seagrass bed (SG) in Hiroshima Bay, western Japan. A total of 2920 fish in 50 species were collected. The number of species, individuals, and biomass (total weight) were greater at SG and MS than at B1 and B2. The numerically most dominant species were Favonigobius gymnauchen and Tridentiger trigonocephalus at B1 and B2, F. gymnauchen and Acentrogobius sp. 2 at MS, and Plotosus japonicus and Rudarius ercodes at SG. Fish diversity also was higher at MS and SG than at B1 and B2 throughout the year. Fish assemblages and their patterns varied between sites, indicating that each habitat plays an important role as the nursery ground for different fishes.
