Description
Summary:No abstracts are to be cited without prior reference to the author.Management of the sub-structured salmonid species may benefit by considering the genetic structure of the species. In the Atlantic salmon (Salmo salar), genetic studies show that populations are genetically distinct, but also that they do not exist in isolation. In this paper, we look at genetic management in a group of populations that are harvested together in the ocean, and separately in fresh water. The scientific problem can be formulated as to combine goals of optimal harvesting and effective population size in a group of populations interconnected by migration. By developing a model that maximises harvesting yield of a group of populations, subject to constraints set by maintaining the total effective size, Tufto & Hindar (2003, J. Theor. Biol. 222:273-81) showed that: (1) Considerable gain can be made in total effective size in a group of populations through harvesting based on knowledge about genetic structure, (2) in source-sink ...
