The Norwegian Gene Bank Programme for Atlantic Salmon (,),d by extinction. Acid precipitation has been the main cause of salmon mortality in the southern part of the country and 25 stocks are now virtually extinct (Hesthagen and Hansen, 1991). The parasite . has caused extensive fish kills in 34 salmon rivers in the middle region of the country.

Genetic Components in Life History Traits Contribute to Population Structure, (.) as well as among the individuals within each population. Numerous electrophoretic studies of allozyme variation document the existence of both inter- and intra- populational genetic variation in Pacific salmon (e.g., Gharrett et al., 1987; Gharrett et al., 1988; Beacham et al., 1988).

We then review the life history, ecology, and genetic population structure of the subspecies, and from this identify gaps in our knowledge that will have to be filled if these populations are to be preserved.
