The first recorded of warm water fishes collected from rivers in Miyagi Prefecture, Japan

Abstract

From 2009 to 2019, four warm water fish species were collected from rivers in Miyagi Prefecture, north of Honshu Island, Japan. Redline pipefish, Microphis (Oostethus) brachyurus brachyurus, rock flagtail, Kuhlia rupestris, and spotted scat, Scatophagus argus, were recorded for the first time from Miyagi Prefecture. These records represent the northernmost, specimen-based, record for these species and are considered to be abortive migrations driven by the Kuroshio Current from the south. On the other hand, Monk goby, Sicyopterus japonicus, was collected from several rivers including wintering individuals.
