Based on the materials collected in August–September 2019 during the Transarctic expedition onboard R/V “Professor Levanidov”, new data on the spatial and vertical distributions, bottom temperatures of habitat and biological features (size-age and size-sex structures, maturation, fecundity, diet composition) of the poorly studied slender eelblenny...
Data on the spatial and vertical distributions, temperature regime of habitat, size-age and, size-sex structure of Arctic alligatorfish Aspidophoroides olrikii in the Kara Sea based on a recent trawl survey are presented. A total of 104 specimens were caught from 9 (out of 55) trawl stations. Maximum catches of this species were recorded north of t...
In the recent years many boreal species demonstrate a significant poleward shift in the distribution and expansion of species range under the influence of climatic changes. Eight species of the righteye flounders were registered during the bottom trawl surveys (234 trawl hauls, depth range 27-270 m) in the western Chukchi Sea (WCS) in 2010, 2018, 2...
Emelin, P.O., Maznikova O.A. Righteye flounders of the western Chukchi Sea: Positive stocks dynamics and species range expansion // 2024 Alaska Marine Science Symposium Abstracts & Poster Presentations (January 29 – February 2, 2024, Hotel Captain Cook and Egan Center, Anchorage, Alaska). NPRB. - 2024. - P. 241.
По материалам, собранным в сентябре 2019 г., представлена биологическая характеристика (размерно-возрастная и размерно-половая структура, плодовитость, состав пищи) люмпена Фабрициуса Lumpenus fabricii Карского моря. Установлено, что для этого вида стихеевых рыб характерен половой диморфизм в размерах – самцы крупнее самок, плодовитость которых вар...
Many fish species have moved poleward with ocean warming, and species distribution shifts can occur because of adult fish movement, or juveniles can recruit to new areas. In the Bering Sea, recent studies document a dramatic northward shift in the distribution of Gadus macrocephalus (Pacific cod in English and tikhookeanskaya treska in Russian) dur...
Based on research of bottom and mid-water trawl surveys conducted onboard Russian research vessels in 2003–2020, data on the spatial and vertical distributions of walleye pollock Gadus chalcogrammus in the western Chukchi Sea are presented. The response of walleye pollock distribution related to water temperature, as well as the features of its dis...
The Laptev Sea is the least studied among the seas of the Russian Arctic due to its remoteness, severe climatic conditions, low human population, lack of stationary research bases and other socio-economic factors.
The aim of the work is to characterize the composition and species structure of the ichthyofauna of the Laptev Sea with a focus on the P...
The Laptev Sea is the least studied among the seas of the Russian Arctic due to its remoteness, severe climatic conditions, low human population, lack of stationary research bases and other socioeconomic factors. The aim of the work is to characterize the composition and species structure of the ichthyofauna of the Laptev Sea with a focus on the Po...
Integrated pelagic trawl surveys were conducted in the eastern sector of the Russian Arctic (Laptev Sea, Chukchi Sea and East Siberian Sea) in August–September of 2003–2018. Data were used to further describe biology and spatial distribution of Polar cod (Boreogadus saida) in this region. Polar cod in surveyed areas are characterized by similar lin...
The purpose of the work is to review the history of the development of walleye pollock stocks in the of Okhotsk sea, to analyze the fishery and the state of its stocks.
Methods: literature data, materials of long-term surveys by VNIRO (1997–2002) on the walleye pollock spawning grounds of Western Kamchatka, as well as the R/V «Professor Kaganovsky...
Presented here are data on the size composition and age structure, the sex ratio, the state of maturity of the gonads, and the composition of the diet and feeding habits of walleye pollock in the western Chukchi Sea, based on 2003-2020 bottom and mid-water trawl surveys conducted onboard Russian research vessels. During all years of research, mid-w...
The features of the spatial and vertical distributions, and size–age and size–sex structures of the ribbed sculpin Triglops pingelii of the Kara Sea are presented. In September 2019, this species was recorded at depths from 18 to 235 m at a bottom temperature from −1.5 to +1.6 ◦C. The densest concentrations were recorded northeastward of the Yamal...
The Arctic staghorn sculpin Gymnocanthus tricuspis is a demersal fish that plays an important role in the Arctic ecosystem as a link between benthic invertebrates and higher trophic levels. In the Kara Sea, the highest density concentrations exceeding six thousand individuals per square km were found in shallow waters (depth 20-30 m) adjacent to th...
Представлены материалы научно-поисковых работ в тихоокеанских водах Курильских островов в сентябре-октябре 2020 г. Совместный поток прибрежной

На основании материалов, собраных в Беринговом море: в западной части в во¬дах России (в 2005–2015 гг.) и в восточной — в водах США (2013–2014 гг.), проведен сравнительный анализ формы отолитов (сагитта) на основе цифрового изображения с использованием программного пакета «Shape V. 1.3», рассмотрены разнообразие форм отолитов и некоторые биологичес...
Geometric parameters of the bottom trawl DT 27.1/24.4 were tested aboard RV TINRO in the Bering Sea using the acoustic equipment «Scanmar» (Norway). Possible errors in the estimates of marine organisms abundance by bottom trawl survey are calculated for different species by comparing the actual data on the trawl geometry with the fixed constant val...

Composition, abundance, diet and trophic status are analyzed for dominant benthic and pelagic species in the deep-water Okhotsk Sea on the data collected in demersal and pelagic trawl surveys conducted by Pacific Fisheries Research Center (TINRO). Isotope composition of13С and15N is determined for tissues of 107 species of plankton, benthos, demers...
In the article, an assessment of chub mackerel and japanese sardine stocks in the Kuril waters of western North Pacific is presented. According to the data from TINRO-Centre trawl surveys in 2013-2015, domination in nekton community has been shifted from mesopelagic species (Northern smoothtongue, Japanese lanternfish) to subtropical migrant specie...
According to the data of trawl catches performed by the R/V “TINRO” in the upper epipelagic zone (0–50 m) of Pacific waters off the Kuril Islands from June 2 to July 8, 2012, the abundance of nekton was the lowest for the recent 9 years; thus, its density in 2012 (1.5 t/km2) was lower than the average value for the 2004–2012 period (2.40 ± 0.39 t/k...
