The purpose of this study was to characterize the life history and spawning habitat of selected stocks of large chinook to elucidate factors responsible for the selection for large size in chinook. This was done through comparison of age structure, size at age, fecundity, freshwater residence patterns and marine catch distribution of four stocks of large-bodied Chinook with coastwide patterns for the species in North America. Physical features of the spawning habitat were also surveyed and assessed including water depth and velocity, substrate size, migration distance, temperature and flow regime.
