Significance of the Stock Concept in Artificial Propagation of Salmonids in Alaska

Abstract

Hatcheries could make a significant contribution to the enhancement of salmonid fisheries if application of this technology is based on principles of the stock concept. Evidence for the stock concept is reviewed and discussed in relation to transplantation of stocks, mating procedures, maintenance of genetic diversity, different methods of artificial propagation, and location of artificial propagation facilities. A strategy is developed for management of both wild and artificially propagated stocks.Key words: hatcheries, salmon, stock concept, genetics, artificial propagation
