    Assessment of the effect of absence of spawning on the fish-farming and biological characteristics of Siberian sturgeon Acipenser baerii (Brandt, 1869) offspring (2022)
    Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) | Moscow (Russia)
    Details
    Publication Date: 2022-12-20
    Description: The article presents the results of studies on the effect of spawning season absence of female Siberian sturgeon of the Lena population on the fish-biological characteristics of the experimental group, as well as the grown-up juveniles in the conditions of industrial farms. The offspring of experimental females that underwent the resorption process, despite the lowest weight of embryos at hatching, maintained a high growth rate throughout the entire rearing period, comparable with juveniles of control groups.
    Description: Представлены результаты исследований о влиянии пропуска нерестового сезона у самок сибирского осетра ленской популяции на рыбоводно-биологические характеристики экспериментальной группы, а также подрощенной молоди в условиях индустриальных хозяйств. Потомство опытной самки, прошедшей процесс резорбции, несмотря на самую низкую массу эмбрионов при вылуплении, на всём протяжении выращивания сохраняло высокий темп роста, сравнимый с молодью контрольных групп.

    Assessment of the influence of temperature on the formation of the Eastern and Western Kamchatka pink salmon population in different life periods (2022)
    Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) | Moscow (Russia)
    Details
    Publication Date: 2022-12-20
    Description: The article presents the results of a comparative analysis of some databases describing SST (sea surface temperature) along the coast of Western Kamchatka with data from domestic weather stations carried out in the villages of Bolsheretsk, Icha, Sobolevo and Ozernovsky. These weather stations monitored air temperature and, in some years, water temperature in adjacent coastal areas. Databases ("10-days-SST", "MGDSST", "HIMSST") that adequately describe the actual curves of water temperature in the coastal area and air temperature in the area of concentration of the main spawning water basins and watercourses (ECMWF V5) have been identified. The selected databases were used to develop long-term series of temperature characteristics in the Kamchatka mainland and some areas of the Bering and Okhotsk Seas used by Western and Northeastern Kamchatka pink salmon at different stages of its life cycle.
    Description: Проведен сравнительный анализ некоторых баз данных (БД) описывающих SST (температуру поверхности воды) вдоль побережья западной Камчатки с данными отечественных метеостанций поселков Большерецк, Ича, Соболево и Озерновский, осуществлявших мониторинг температуры воздуха и в отдельные годы температуры воды в прилегающих участках прибрежья. Выявлены БД («10-days-SST», «MGDSST», «HIMSST») адекватно описывающие фактический ход температуры воды в прибрежье и температуры воздуха в районе концентрации основных нерестовых водоемов и водотоков (ECMWF V5). Выбранные базы данных использовались для построения продолжительных рядов температурных характеристик в материковой части Камчатки и некоторых районов Берингова и Охотского морей, используемых горбушей западного и северо-восточного побережий Камчатки на разных этапах своего жизненного цикла.

    Fin whale (Balaenoptera physalus) distribution modeling on their Nordic and Barents Seas feeding grounds (2022)
    WILEY-BLACKWELL PUBLISHING
    In:  EPIC3Marine Mammal Science, WILEY-BLACKWELL PUBLISHING, ISSN: 0824-0469
    Details
    Publication Date: 2022-05-30
    Description: Understanding cetacean distribution is essential for conservation planning and decision-making, particularly in regions subject to rapid environmental changes. Nevertheless, information on their spatiotemporal distribution is commonly limited, especially from remote areas. Species distribution models (SDMs) are powerful tools, relating species occurrences to environmental variables to predict the species' potential distribution. This study aims at using presence-only SDMs (MaxEnt) to identify suitable habitats for fin whales (Balaenoptera physalus) on their Nordic and Barents Seas feeding grounds. We used spatial-block cross-validation to tune MaxEnt parameters and evaluate model performance using spatially independent testing data. We considered spatial sampling bias correction using four methods. Important environmental variables were distance to shore and sea ice edge, variability of sea surface temperature and sea surface salinity, and depth. Suitable fin whale habitats were predicted along the west coast of Svalbard, between Svalbard and the eastern Norwegian Sea, coastal areas off Iceland and southern East Greenland, and along the Knipovich Ridge to Jan Mayen. Results support that presence-only SDMs are effective tools to predict cetacean habitat suitability, particularly in remote areas like the Arctic Ocean. SDMs constitute a cost-effective method for targeting future surveys and identifying top priority sites for conservation measures.

    Description: The population and genetic structure of chum salmon in the main reproduction regions of the Russian Far East is presented based on the variability of eight microsatellite loci (Ssa20.19, One101, Oke3, Oki1b, Oki23, Ogo2G, Oke11, Ots102). Four main regional groups have been identified for the purposes of genetic identification. The accuracy of the estimates obtained is calculated for each of the four groups. The authors present the results of genetic identification according to the autumn trawl survey in the Sea of Okhotsk in 2019.
