Comparative analysis of genetic variability of white sea cod (Gadus morhua marisalbi) at allozyme and microsatellite markers

First evidence of spawning of eastern Baltic cod (Gadus morhua callarias) in the Belt Sea, the main spawning area of western Baltic cod (Gadus morhuaL.)

“…This means that currently mainly spawners of EBC were observed in the Arkona Sea. This in return, supports the results of Nielsen et al (2003Nielsen et al ( , 2005, Stroganov, Bleil, Oeberst, Winkler, and Semenova (2013), Stroganov, Cherenkova, Semenova, Afanasiev, and Andreeva (2013) and Eero et al (2014) which were also based on the analyses of microsatellites. On the other hand, Pedersen (2009) found that in 2008 the analysed individuals of the Arkona Sea were genetically similar to EBC while the ones in 1996 were similar to WBC.…”

“…This in return, supports the results of Nielsen et al. (, ), Stroganov, Bleil, Oeberst, Winkler, and Semenova (), Stroganov, Cherenkova, Semenova, Afanasiev, and Andreeva () and Eero et al. () which were also based on the analyses of microsatellites.…”

“…Currently, mainly spawners with the genetic signature of EBC are observed. This is confirmed by Nielsen et al (2003Nielsen et al ( , 2005, Stroganov, Bleil, et al (2013); Stroganov, Cherenkova, et al (2013) and Eero et al (2015), also based on the analyses of microsatellites. However, additionally we can show in the present article, that in the Arkona Sea but also in the Bornholm Sea not only in the summer, but surprisingly also in spring, mainly spawning cod with EBC signal were found.…”

Genus Gadus (Gadidae): Composition, distribution, and evolution of forms

“…Low degree of genetic differentiation (homoge nous structure) of the White Sea cod (allozymes and microsatellites) was found; this group differed signifi (Nei, 1972(Nei, , 1978; θ and F ST -differentiation levels; numbers above the line refer to the Atlan tic cod and those below the line refer to the Pacific cod; *significant at 95% confidence bootstrap interval, **significant at p < 0.05. cantly by the nuclear DNA (microsatellites, Table 4) from the Atlantic cod inhabiting the Barents Sea (Stroganov et al, 2013a). The results of the up to date morphological and genetic analysis allow us to reject the hypothesis of habitation of the White Sea by the group of the Atlantic cod G. morhua morhua natio hie malis (Svetovidov, 1948;Cohen et al, 1990).…”
