“…The data presented here clearly indicate that the few records of walleye pollock in the North Atlantic have their origin from the North Pacific, and its range extends almost continuously from the coast of Norway in the North Atlantic to the coasts of Korea, Japan, and California in the North Pacific. Walleye pollock has not yet been found in the East Siberian Sea, since research there is extremely rare and limited in that area [85,86]. However, the discovery of walleye pollock in the East Siberian Sea, in our opinion, is a matter of the near future.…”

The first records of walleye pollock Gadus chalcogrammus Pallas, 1814 in the seas of the Siberian Arctic (the Laptev Sea, the Kara Sea, the southeastern Barents Sea), are documented. Information about the external morphology (morphometric and meristic characters), photos of sagittal otoliths and fish, and data on the sequences of the CO1 mtDNA gene are presented. The results of a comparative analysis indicate that walleye pollock caught in the Siberian Arctic do not differ in principle from North Pacific and North Atlantic individuals. Previous conclusions about the conspecificity of the walleye and Norwegian pollock Theragra finnmarchica are confirmed. New captures of walleye pollock in the Siberian Arctic allow us to formulate a hypothesis about its continuous species’ range from the coasts of Norway in the North Atlantic to the coasts of Korea, Japan, and California in the North Pacific. The few records of walleye pollock in the North Atlantic originate from the North Pacific due to the transport of early pelagic juveniles to the Arctic by currents through the Bering Strait and further active westward migrations of individuals which have switched to the bentho-pelagic mode of life.

“…Saffron cod were not listed for Chaunskaya Bay in the western East Siberian Sea (Neelov 2008;Chernova 2022) nor caught in trawl surveys on shelf of the East Siberian Sea (e.g. Glebov et al 2016;Orlov et al 2020c). Although saffron cod are included in a few compilations of sh species of the East Siberian and Laptev seas), there is no documentation.…”

Demography of a nearshore gadid navaga, Eleginus nawaga, from the Barents Sea coast during the last glacial period

et al. 2023

Recent glaciations in northwestern Russia completely covered the Barents Sea during four glacial advances. At the peaks of those glacial advances, there were no nearshore macrofauna. Consequently, colonization by species that now inhabit present-day nearshore waters must have occurred since the habitat became available and hospitable, less than 15 ka. We analyzed microsatellite data from Eleginus nawaga (Gadiformes: Gadidae) collected from Khaipudyrskaya Bay in the southeastern Barents Sea with coalescent-based models to estimate the times and effective population sizes that existed before and after major historical demographic changes. Colonization of E. nawaga, which could only follow establishment of a lower trophic-level food web, provides an indicator of the for that timing. The results of the analyses were consistent with two major demographic events. After an initial founding event from a small number of individuals before ~ 140 ka, the population grew to an effective size of about 2700 individuals. Subsequently, probably as the ice receded after the Last Glacial Maximum, it plateaued at ~ 26,000 about 3000 years ago. Colonization likely came from eastern populations following the Saalian Period, after which there was little nearshore ice to the East of the Kara Sea.

“…Global temperature rise has a significant impact on the Arctic, which has already led to a 50% reduction in the area of ice cover from 2002 to 2017 (Kwok, 2018). First of all, the changes affected shallow shelf seas, including the Laptev and East Siberian Seas, which made it possible to conduct studies in areas previously inaccessible to bottom trawling (Chernova, 2015;Glebov et al, 2016aGlebov et al, , 2016bOrlov et al, 2020aOrlov et al, , 2020bSyomin and Zimina, 2020). This study presents the results of analysis of catches taken during large-scale trawl surveys in the above seas in 2014 and 2017.…”

Species Composition, Abundance, Distribution Features and Size Characteristics of Fish of the Genus Liparis (Cottiformes: Liparidae) in the East-Siberian and Laptev Seas

2022

Abstract— Information on the distribution and occurrence of three species of the genus Liparis, Liparis bathyarcticus Parr, 1931, L. cf. fabricii Krøyer, 1847 and L. tunicatus Reinhardt, 1836 on the shelf of the Laptev and East Siberian seas, depending on the temperature, salinity and sediment types is presented according to the data of trawl surveys in 2014 and 2017. L. cf. fabricii is the most common species in the surveyed water area with the frequency of occurrence of 22.4% in the Laptev Sea and 24.7% in the East Siberian Sea. The total relative abundance and biomass of all species of the genus Liparis in the East Siberian Sea (377.7 ind./km2 and 9.14 kg/km2) were slightly higher than in the Laptev Sea (326 ind./km2 and 8.32 kg/km2). The maximum length of L. tunicatus in the East Siberian Sea (172 mm) exceeds the previously known one (160 mm). The average length and weight of fish of all three species of Liparis in the East Siberian Sea are greater than in the Laptev Sea.
