|General description of research on brown trout population
|Previously involved in population genetic studies of
brown trout (and hybrids) using allozyme and minisatellite DNA markers. Currently no work
is being undertaken specifically on brown trout. Research is focused on behavioural and
population genetics of Atlantic salmon (Salmo salar) using highly variable nuclear
DNA markers (mini- and microsatellites). A major part of this work involves an intensive
and long term genetic monitoring programme of salmon from two tributaries within a large
river system. DNA profiling is being applied to assess / measure a variety of traits e.g.
mate preference, spawning success, juvenile survival / distribution, timing of
smoltification, etc. The goal is to monitor family groups throughout their life cycle and
ultimately measure the reproductive success of different life history strategies. The
laboratory is also a partner in the EU funded salmonid genome mapping project (SALMAP).
