Record of a cottid fish, Icelinus pietschi, collected from Hokkaido and Miyagi Prefecture, Japan

Abstract

Seven specimens of cottid fish, Icelinus pietschi Yabe, Soma and Amaoka, 2001, were collected from the shallow waters off Oshoro Bay and Usujiri (western Hokkaido) and Onagawa (Miyagi Pref.), Japan. This species was previously known only from the Iturup Island of southern Kuril Archipelago. The present specimens were secondly recorded to be the southernmost record for this species. In addition, colorations of fresh specimens, reproductive ecology of this species, and the intraspecific variation of the dorsal scale rows were briefly commented.
