Abstract
The feasibility of incorporating a unique genetic marker into a hatchery strain of brown trout is investigated. The allele Pgi-3(110) is shown to have a very limited distribution among native trout populations in Great Britain and Ireland yet is present, at low frequency, in all three hatchery stocks examined. The potential therefore exists to breed a strain of hatchery brown trout homozygous for the Pgi-3(110) allele. Individuals of such a strain could be unambiguously distinguished from virtually all native stocks. The usefulness of the genetic tag is enhanced by the strong expression of Pgi-3 in adipose fin, permitting simple biopsying. Data from population surveys and the monitoring of experimental progeny suggest selective equivalence among Pgi-3 genotypes.
