“…Research in the Rayakoski reservoir in 2002 and 2004 showed a wider range in the distribution of whitefish rakers (16-44), which narrowed in 2012-2013 (20-34) (author's unpublished data). It was shown previously that the introduction of vendace and its colonization of the upper reaches of the Pasvik River in the 1990s led to its domination in the pelagic zone and the displacement of the mr whitefish into the littoral and profundal zones with an overlap within the niches occupied by the sr whitefish (Kashulin et al 1999;Reshetnikov et al 2020;Amundsen et al 1999). The absence of spatial segregation could have contributed to the hybridization of the mr and sr whitefish morphs and the convergence of traits (Bhat et al 2014).…”

European whitefish (Coregonus lavaretus) is a highly polymorphic species, but the wider scale diversity and distribution of sympatric morphs in subarctic lakes of northwestern Russia has not been recently studied and analyzed. The aim of the present study was to investigate diversity and distribution of whitefish morphs in different sized lakes and watercourses of Murmansk region. Our study of the water bodies in four major river basins of Murmansk region revealed the presence of two whitefish morphs: sparsely rakered (sr) and medium rakered (mr). The mr morph is less common and observed only alongside the sr whitefish. In general, in sr whitefish the number of gill rakers ranges between 15 and 31, and in mr whitefish between 27 and 44. Among whitefishes with 27 to 31 gill rakers, both sr and mr morphs were observed and distinguishable by the shape of the rakers. In the studied sr whitefish populations, relatively long and short rakered whitefish morphs were found. In Lake Kuetsyarvi (Pasvik River basin), the sr and mr whitefish formed additional slow-and fast-growing ecological morphs. The four whitefish morphs in Lake Kuetsyarvi specialize to different ecological niches correlating with morphological and behavioral differences. The observed diversity and distribution of whitefish in the Murmansk region requires genetic studies of the population to assess the origins of divergence.

“…Despite having only been able to establish within a limited spatial range in the Baltic Sea, C. albula exhibits a significant potential to adapt to local conditions. Sympatric forms that occupy different niches with respect to the timing of spawning (Delling & Palm, 2019;Schulz & Freyhof, 2003;Sendek, 2021), spawning migrations (Bogdanov et al, 2021), body size and growth (Reshetnikov et al, 2020;Strelnikova & Berezina, 2021), and diet (Strelnikova & Berezina, 2021) have been documented both in lakes and the Baltic Sea. For example, Strelnikova and Berezina (2021) reported the existence of small and large-sized C. albula forms in the Gulf of Finland, with the latter occupying areas of deeper water.…”

“…One of these, C. albula, occupies the least saline parts of the Baltic Sea. While the species' distribution is limited by salinity in combination with other factors (Bergenius et al, 2013;Jäger et al, 1981), it also exhibits remarkable local adaptations and even sympatric forms that occupy slightly different niches (Reshetnikov et al, 2020;Strelnikova & Berezina, 2021). The vendace fishery is economically important on the Swedish side of the Bothnian Bay, recovering on the Finnish side (Figures 2 and 3 assumed that the Swedish coast of the Bothnian Bay would be a significant source for adult C. albula on the Finnish side (Hildén et al, 1984), whereas a subsequent tagging assessment suggested more localized breeding populations (Enderlein, 1989).…”

Brackish water ecosystems often have high primary production, intermediate salinities, and fluctuating physical conditions and therefore provide challenging environments for many of their inhabitants. This is especially true of the Baltic Sea, which is a large body of brackish water under strong anthropogenic influence. One freshwater species that is able to cope under these conditions in the northern Baltic Sea is the vendace (Coregonus albula), a small salmonid fish. Here, we review the current knowledge of its ecology and fishery in this brackish water environment. The literature shows that, by competing for resources with other planktivores and being an important prey for a range of larger species, C. albula plays a notable role in the northern Baltic Sea ecosystem. It also sustains significant fisheries in the coastal waters of Sweden and Finland. We identify the need to better understand these C. albula populations in terms of the predator–prey interactions, distributions of anadromous and sea spawning populations and other putative (eco)morphs, extent of gene exchange between the populations, and effects of climate change on their future. In this regard, we recommend strengthening C. albula‐related research and management efforts by improved collaboration and coordination between research institutions, other governmental agencies, and fishers, as well as by harmonization of fishery policies across national borders.

“…Murmansk Region is one of the largest developed and urbanised parts of the Northern-European Russia. Due to extensive pollution of the water bodies in the second half of the 20 th century, the focus of researchers has been on fishes as the bioindicators ( Reshetnikov 1968 , Reshetnikov 1980 , Moiseenko 1983 , Moiseenko 1991 , Moiseenko 1996 , Moiseenko 1997 , Moiseenko 2000 , Moiseenko 2002 , Moiseenko and Yakovlev 1990 , Nost et al 1991 , Nost et al 1997 , Lukin and Kashulin 1992 , Lukin 1998 , Moiseenko et al 1994 , Sharova and Lukin 2000 , Kashulin et al 1999 , Kashulin et al 2005 , Kashulin et al 2007 , Kashulin et al 2009 , Moiseenko and Lukin 1999 , Moiseenko et al 2002 , Kashulin 2004 , Terentyev 2005 , Lukin et al 2006 , Reshetnikov et al 2011 , Reshetnikov et al 2020 , Koroleva et al 2012 , Terentyev and Kashulin 2012 , Zubova 2015 , Zubova et al 2015 , Zubova et al 2016 , Zubova et al 2018 , Zubova et al 2020a , Zubova et al 2020b , Zubova et al 2020c , Terentyev et al 2017 , Terentyev et al 2019 , Denisov et al 2020 ).

Knowledge about the distribution of organisms on Earth is important backbone of biological sciences and especially for deeper understanding of biogeography. However, much of the existing distributional data are scattered throughout a multitude of sources (including in different languages), such as taxonomic publications, checklists and natural history collections and often, bringing them together is difficult. Development of the digital storage facilities may prevent loss of important data (Ruchin et al. 2020). Project GBIF is a good example of a successful data storage facility, which allows investigators to publish biodiversity data in one safe place in one uniform format. Our dataset describes the degree of the investigation of the fish fauna of the inland water of the Murmansk Region. Murmansk Region is a Euro-Arctic Region with a heterogeneous landscape, which determines diversity of the habitats for the fish occurrence. Our dataset contains valid information about distribution of the fish species. This dataset was built upon information obtained by the members of a Laboratory of the aquatic ecosystems of the Institute of North Industrial Ecology Problems of Kola Science Center of the Russian Academy of Science (INEP KSC RAS). The dataset includes 18,509 records about 16 fish species from 14 genera (eight families) collected from 1972 to 2021. A total of 67 water bodies from 15 different basins (rivers from basins of the White and Barents Seas) was screened in order to characterise ichthyocenoses. The main purpose of publishing a database is to make our data available in the global biodiversity system to a wide range of users. The data can be used by researchers, as well as helping the authorities to manage their territory more efficiently. All occurrences are published in GBIF for the first time. We would like to make this data available to everyone by adding it in the global biodiversity database (GBIF).
