Abstract

Field sampling has never been performed in Yoro-jima and Uke-jima islands in the Amami Islands, Ryukyu Archipelago,
southern Japan. 172 species (50 families) and a single species have previously been reported from Yoro-jima and Uke-jimaislands, respectively, but these records (except for a single species from Uke-jima island) were based on visual recordings,
and some of the identifications of the listed species are doubtful. Therefore, field sampling for three days at each island
was conducted, and 182 specimens (89 species, 35 families) were collected. The present paper lists a total of 195 species
of marine fish species occurring around Yoro-jima and Uke-jima islands on the bases of collected specimens and a single
published piece of literature.
