“…Lycodes nakamurae belongs the family Zoarcidae, which is known as one of demersal fishes caught by trawl nets (Møller & Jørgensen, 2000;Okiyama, 2004;Balanov & Solomatov, 2008). In the present study, L. nakamurae fed also on mysids and cumaceans, which are typically benthic crustaceans, since it is reported that mysids living near the sea bottom are dominant in the fishing grounds of P. japonica (Nanjo, 2007) and cumaceans are mainly benthic (Gamo, 1997).…”

Abstract. The purpose of present study is to clarify the predation of P. japonica including larvae by investigating guts of predators caught as a by-catch in the P. japonica fishery. The by-catch, including fish, cephalopods and decapods, were caught once or twice a month between April and November 2008 in a submarine canyon adjacent to the mouth of the Jinzu River in Toyama Bay. Size of the potential predators was measured and the gut contents were identified to the lowest possible taxa. Ostracods, copepods, mysids, cumaceans, amphipods, euphausiids, and decapods were the most common prey in the gut contents of the predators. Pasiphaea japonica, including larvae before metamorphosis, were preyed upon by demersal fishes Crystallichthys matsushimae, Lycodes nakamurae, and Bothrocara hollandi. Occurrence of P. japonica in the guts of these predators may be due to the aggregation of larvae in the canyon head which is enclosed by the steeply sloping bottoms and the truncation of the vertical migration of P. japonica from the pelagic to the benthopelagic environment.

“…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.…”

“…1, 2). In the sum mer, L. tanakae in the Tatar Strait migrates upwards into the 50-100 m isobaths, but this is not the case for the Primorye, where only two records of this species at 64 and 87 m depths are known [1,2].…”

“…The biology of most zoarcid species has been poorly studied. 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].…”

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.

“…Regular bottom trawl surveys have been con ducted in the bay since 1984. Based on the results of these surveys, the data on the distribution and occur rence of rare and not previously registered fish species have been obtained (Izmyatinskii et al, 1999;Antonenko et al, 2003aAntonenko et al, , 2003bAntonenko et al, , 2004Izmyatinskii and Kim, 2003;Balanov and Solomatov, 2008;Solo matov et al, 2009). Ivankov et al (2001 reviewed the data on the invasion of warm water species into the northwestern Sea of Japan in the 1990s, and Sokolovskii et al (2004a) described the changes in the composi tion of southern migrants in the region over the cen tury.…”

The information on the catches of rare fish species in Peter the Great Bay is presented based on trawl surveys. Several species that have not been observed previously are registered. The species composition of Peter the Great Bay has changed in recent years because of two multidirectional hydrological processes. The rise of surface water temperature leads to the increasing number of southern migrants, and the decrease of heat content of near bottom waters in the shelf is favorable for the invasion of fishes of boreal origin into the bay.
