|General description of research on
brown trout population genetics:
|To date, we have conducted research into the population
structure of S.trutta using mitochondrial DNA and microsatellite loci to examine
patterns of genetic variation within and among rivers in England and Wales. In particular,
we have used molecular techniques to investigate genetic differences between resident and
anadromous groups of fish within single populations, and between early and late-running
groups in migrating sea trout smolts and adults. In future we will concentrate on
examining the genetic basis of homing and local adaptation in brown trout populations,
using our experience with Atlantic salmon as a basis for work on trout.

the past 3 years:
| Study #1
||H. J. Hall, W. C. Jordan, and M. W. Bruford
||Audun Slettan, Department of Morphology, Genetics and
Aquatic Biology, Norwegian College of Veterinary Medicine, P.O. Box 8146 Dep., N-0033
|Source of project
||National Rivers Authority (now Environment Agency).
||Conservation, management of subdivided populations, genetic
population structure, gene diversity, gene flow, isolation by distance, temporal
||To describe the stock structure of sea trout in England and Wales
using genetic techniques, and to use these techniques to address questions on the biology
of sea trout with particular reference to timing of migration.
||Samples from various S.trutta populations were analysed for
variability in mitochondrial DNA and at microsatellite loci. For some populations
individual samples were classified as resident or anadromous. Trap facilities were also
used to collect samples during sea trout migrations (smolts and adults).
||MtDNA RFLP, single locus minisatellites, microsatellites.
||Resident and anadromous populations.
|Origin of samples:
||England and Wales, North Sea Basin.
||Currently being written up for publication.
