Genetic variation of Sebastes viviparus Kroyer in the North Atlantic

As part of a more extensive study on the inter- and intraspecific genetic variation of redfish, genus Sebastes, a total sample of 593 individuals of the species Sebastes viviparus were collected from several locations in Norwegian waters and off the south-west coast of Iceland. Haemoglobin and five polymorphic enzymes were analysed. A new haemoglobin polymorphism was observed, and unique alleles were found in Icelandic and Norwegian samples. The results of the enzyme analyses were largely consistent with previous results, but interpopulation variation was observed in the frequencies of IDHP* and Hb* alleles. S. viviparus displayed higher similarity with S. fasciatus from the West Atlantic than with the other Sebastes species.
