Abstract

Electrophoretic analysis of liver enzyme variants from redfish specimens, classified as Sebastes marinus and Sebastes fasciatus on the basis of meristics and gas bladder musculature, provides clear evidence that these taxa are valid biological species. It is also evident that S. fasciatus and S. mentella are genetically distinct and that S. mentella is more closely related to S. marinus than to S. fasciatus. These preliminary analyses indicate that it may soon be possible to devise a biochemical genetic protocol that will readily and accurately distinguish specimens of the three sibling redfish species in the Northwest Atlantic.
