Description
Summary:Starch gel electrophoresis of plasma transferrin phenotypes from 710 scad caught on four research vessel cruises in the North Sea, Celtic Sea, Bay of Biscay, and off the Portuguese coast was carried out in an attempt to assess the genetic identity of populations of this species in the north-east Atlantic. Four allelic variants are described, although three of these proved to be only rare alleles, and no significant heterogeneity in the populations from all four areas was identified. These results are discussed in relation to previous analyses of genetic polymorphisms in scad populations in this area. We conclude that, at present, the genetic evidence provides no support for the existence of genetically distinct stocks of scad in the north-east Atlantic.
