“…This layer, with a temperature of 0-2°C, occurs here during the entire summer [5]. Because of this temperature regime in the Tatar Strait shelf area, L. tanakae can migrate to the 50 m depth, which is not the case for waters of Pri morye and the southeastern coast of the Republic of Korea [3].…”

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.

The feeding habits of Lycodes tanakae Eelpout were studied with 722 specimens collected from March 2011 to December 2012 in the coastal waters of the middle East Sea. The main prey of L. tanakae were fish, molluscs and arthropods. Nevertheless annelida, echinodermata and others were found in small amounts in the stomach contents. The L. tanakae stomach was empty of contents in 50.9% of specimens. While smaller size specimens of L. tanakae (less than 40 cm) fed mainly on euphausiids and amphipods, the larger specimens (more than 40 cm) fed on the fish Allolepis hollandi and Icelus cataphractus, and the molluscs Berryteuthis magister and Watasenia scintillans. The main prey items of L. tanakae varied seasonally. The fish Lycodes nakamurai was the dominat prey from November to January during its spawning season. Euphausiids and amphipods of the arthropods were the dominant prey from February to April. The molluscs Berryteuthis magister and Watasenia scintillans were the dominant prey from May to September. The diversity index (H') of diets showed variations by length class and month; the highest values were 2.61 in the length class of 51-55 cm, and the monthly highest were 2.68 in September with 23 species and 2.65 in November with 18 species. The highest dominance index (D') of diets was 0.57 in the length class of 31-35 cm, and the monthly highest was 0.71 in February. Cluster analysis divided prey groups into four groups by length class and three groups by monthly prey items. The gonad index gradually increased during the process of maturation while, contrary, stomach content index decreased during this period.
