Mitogenomic analyses of Arctic cod and three other co-distributed gadoids (Polar cod [Arctogadus glacialis], Saffron cod [Eleginus gracilis], Walleye Pollock [Gadus chalcogrammus]) were also completed. Transcriptomic analyses of Arctic cod were used to identify genes associated with environmental perturbations.
