Biochemical separation of Atlantic Canadian redfish: Sebastes mentella and Sebastes norvegicus
One of the problems for management of the redfish fishery in the Gulf of St. Lawrence is the difficulty in distinguishing between the different species: deepwater redfish (Sebastes mentella), golden redfish (Sebastes norvegicus), and Acadian redfish (Sebastes fasciatus). Controversy exists concernin...
