Description
The illiosentid acanthocephalan Pseudorhadinorhynchus leuciscus (Krotov & Petrochenko, 1956) was collected from the intestine of big-scaled redfin, Tribolodon hakonensis (Günther, 1877), at four sites in coastal marine waters of Hokkaido, northern Japan. These collections indicate that this acanthocephalan is an intestinal parasite of T. hakonensis inhabiting the coastal marine waters. The host fish is known to consist of two ecologically different, river-resident and anadromous, individuals. We suggest a practical use of P. leuciscus as a biological tag to identify the anadromous individuals of T. hakonensis that migrate from the sea to and stay in rivers during their spawning period.
