Spatial distribution and thermal regime of habitation of two representatives of the genus Lycodes (Perciformes: Zoarcidae) in Russian waters of the Sea of Japan

On the colour types in Lycodes nakamurae (Tanaka, 1914) and species composition of the subgenus Furcimanus (Perciformes: Zoarcidae: Lycodes) in the Sea of Japan

“…However, when describing the discovery of L. pectoralis from the Republic of Korea, the authors did not indicate any of the diagnostically important characters of this species (presence or absence of scales before the dorsal fin, preanal distance to TL ratio), citing instead a series of characters peculiar to almost all eelpout of the subgenus Furcimanus (Kim et al 2006). This species has never been found either in the northern or southwestern Sea of Japan despite the other intensive investigations conducted in these areas (Hatooka 2002;Balanov & Solomatov 2008;Dolganov & Saveliev 2013;Saveliev et al 2014). The upper depth limit of L. pectoralis (150 m) excludes its penetration into the Sea of Japan from the southern Sea of Okhotsk through the shallow La Perouse Strait (maximum depth 53 m).…”
