Notes on Five Fish Species Recorded from the Rivers and Coastal Areas of Sagami Bay and Adjacent Waters, Japan

Abstract

Five fish species collected from the rivers and coastal areas of Sagami Bay and adjacent waters were briefly described to document the effects of a rising trend in sea surface temperature in those areas in response to global warming. Two tropicalsubtropical species, i.e. Monodactylus argenteus and Oxyurichthys visayanus, were newly reported from the Kanto area representing the northernmost records for the species. A rare tropical–subtropical species, Eleotris acanthopoma, was recorded for the first time from the rivers flowing to Tokyo Bay in Kanagawa Prefecture. The occurrence of Plectorhinchus gibbosus in Shimoda represents a new record from Sagami Bay. A rare temperate species, Hippichthys penicillus, was also noted.
