Habitat use by benthic juveniles of the threatened goby Gymnogobius castaneus was investigated at 94 sites in a brackish water body, Lake Hinuma, and eight inflowing rivers from June to July 2021, following the recruitment period of the species. During the study period, the goby occurred in the lower river reaches and around the river mouths, but rarely in the lake. A generalized linear mixed model based on presence/absence data of benthic juveniles with seven environmental variables at each site revealed that lower salinity, higher reed density and muddy
to sandy substrate were the most significant determinants for the presence of benthic juveniles.
Such environmental features should be maintained for the conservation of juvenile habitat for the species.
