abstract
Nine and three specimens of the fish leech Limnotrachelobdella okae (Moore, 1924) were found in the stomach and oral cavity, respectively, of a satsuki-masu salmon Oncorhynchus masou ishikawae caught at the mouth of the Kiso River, Mie Prefecture, central Japan in March 2009. The specimens from the oral cavity were likely expelled from the stomach immediately after fish capture because one of them was slightly digested and the cavity is not usually an attachment site for L. okae. The leeches found appear to have been fed on by the fish in coastal waters of Ise Bay, into which the Kiso River empties, when they detached from fish hosts. This is apparently the first record of L. okae as prey for fishes.
