Atlantic fishes in the Chukchi Borderland

Ichthyofaunal Baselines in the Pacific Arctic Region and RUSALCA Study Area

“…of users, providing current baselines against which change may be detected. Our methods, described in earlier papers (Mecklenburg et al, 2007(Mecklenburg et al, , 2011(Mecklenburg et al, , 2014, involve study of historical fish collections in museums, sampling by modern investigations including RUSALCA multidisciplinary expeditions, and review of the ichthyological and fisheries science literature combined with results from DNA barcoding. The basic quest is to determine the geographic distributions and taxonomic identity of the species in the region.…”

“…Catch records in the literature and museum records were reviewed for accuracy of identifications from our examination of voucher specimens (e.g., Norcross et al, 2013). We focused on museums with significant collections of Arctic fishes, listed in Mecklenburg et al (2011Mecklenburg et al ( , 2014. The museum work has remained a critical focus of our studies.…”

The ecology of gadid fishes in the circumpolar Arctic with a special emphasis on the polar cod (Boreogadus saida)

“…comm.). Others consider A. glacialis to be a single circumpolar species based on morphology and genetics (Jordan et al 2003;Aschan et al 2009;Mecklenburg et al 2014;Mecklenburg and Steinke 2015). In both the Atlantic and the Pacific Arctic, A. glacialis overlaps with B. saida, but is generally much less abundant (Madsen et al 2016;Bouchard et al 2016).…”

“…In high-Arctic marine ecosystems, the gadids Boreogadus saida (Lepechin, 1774) and Arctogadus glacialis, hereafter referred to as polar cod and Arctic cod, as respective European common names, are foundation species that make up important links between lower and higher trophic levels of the food web (Bradstreet et al 1986;Christiansen et al 2012;Hop and Gjøsaeter 2013). Other Arctic gadids considered here are the saffron cod [Eleginus gracilis (Tilesius, 1810)], which is endemic to the Pacific Arctic but extends into boreal waters as far south as Japan (Mecklenburg et al 2002), and its Atlantic sister species, the navaga [Eleginus navaga (Walbaum, 1792)], which is limited to European Arctic and subarctic waters of the Barents, White and Kara seas (Cohen et al 1990). There is a strong imbalance in the scientific literature regarding these species-a search for the words ''Boreogadus'' in Google Scholar (April 2016) resulted in 4010 hits, compared to only 522 hits for ''Arctogadus,'' reflecting a greater emphasis on the more abundant polar cod.…”
