Abstract
Research on the biology of the anadromous red salmon of Bristol Bay, Alaska, was financed by the canning industry. The features of its life history which shaped the program and its evolution are described. Numerous small, independent, spawning populations exist in the lakes and streams. During seaward migration, the young form successively more complex mixtures and then segregate progressively as they return to spawn in their home streams, where interbreeding occurs within each local stock. When thus segregated the summer mortality of the life of the generation is most evident in the variability of these units. Each mixture during the homeward migration of the adults must then have an abundance which is based upon the varying productivity of its components, hence in any given generation it must be much more stable in numbers that the individual components.
