“…In both regions, this species was most common in the 200-600 m depth range and showed seasonal migrations, during the summer mov ing from the wintering places (the continental slope below 400 m) to the shelf and returning during the fall-winter period [2,9]. However, substantial differ ences between the regions were found in the distribu tion of L. tanakae by depth.…”

“…However, substantial differ ences between the regions were found in the distribu tion of L. tanakae by depth. Off Primorye, the young of this species (less than 30 cm in TL) are concentrated year round at 200-350 m [9], while in the Tatar Strait they are found at 100-200 m in the spring and 50-200 m depths in the summer (Figs. 1, 2).…”

“…The material was examined under an MBS 10 binocular microscope, applying glycerol or water on the chipped off surface to achieve a leveling effect of the lens. The length, weight, and age data were analyzed without dividing the sample according to the sex of the fish because sexual dimorphism with respect to these characteristics was not found in L. tanakae [9].…”

“…Among the eelpouts of the Sea of Japan, Lycodes tanakae Jordan et Thompson, 1914 is a common and widely distributed species; it is inferior in frequency of occurrence in catches only to Bothro cara hollandi, another common zoarcid species [2,14]. A recent publication reported data on the spatial distribution of size groups, the size-weight and age composition, and feeding habits of L. tanakae in waters of Primorye [9]. In the present paper, we exam ine the spatial distribution and some traits of the biol ogy of L. tanakae in the Tatar Strait of the Sea of Japan.…”

Based on data from studies that were performed in 2006, 2007, and 2009, we analyzed the distri bution and some features of the biology of the eelpout Lycodes tanakae, which inhabits the Tatar Strait. The young of this species (<30 cm in TL) predominantly occur to the north of 50° N. The largest individuals (>71 cm in TL) are found to the south of 49° N and medium sized fish occur throughout the studied area. In the Tatar Strait, L. tanakae inhabits the 50-615 m depth range, but the majority of the eelpouts (67.9%) were caught from depths of 200-600 m. Small individuals of this species (<30 cm in TL) occur at depths of 50-200 m, while medium sized and large fish (>30 cm in TL) can be found at all depth horizons that were sur veyed. The mean linear size of L. tanakae increases with an increase in the depth of their habitat. The rela tionship between the spatial distribution of L. tanakae and water temperature regime is discussed. The nutri tional spectrum of L. tanakae includes 18 food items, with fish and shrimp predominating. Young L. tanakae (<30 cm in TL) are benthophages, 41-50 cm individuals feed mainly on cephalopods and fish.
