Allele frequency variation at the SAAT-4 locus as a potential measure of the relative performance of native and introduced Atlantic salmon in the River Test

Allele frequency at the _sAAT-4 locus as a potential measure of the relative performance of native and introduced Atlantic salmon in the River Test

D. Thompson and I.C. Russell

Attempts are being made to enhance the salmon stock of the River Test in the south of England by the introduction of hatchery-reared parr. These fish are being reared from both local and 'non-local' broodstocks. A significant difference in allele frequencies at the _sAAT-4 locus has been identified between batches of parr from different origins. The hatchery-reared fish have been microtagged and finclipped before release. This enhancement exercise, if combined with an effective method of monitoring and sampling returning salmon, could give some insight into the immediate effect of an introduction of `non-native' fish and the genetic interaction between these fish and the native population.
