Salmon and sea trout are valuable in multiple ways. The Trust’s work concentrates on improving our knowledge of these fish, their habitats and their complex and fascinating life histories, so that they can be managed sustainably and conserved for future generations. The AST has helped support many projects over the years with funding to research being undertaken by other organisations that apply to the AST for funding. In recent years the AST has focused its efforts on its Sea Trout Research Programme and on developing ways of learning more about salmon at sea, in particular their migration routes and causes of increased marine mortality, described under AST Projects.
