Utilizes a statistical method which allows the data to determine the interrelationship of smolts and adult production mean and variability without imposing a priori restrictions on the form of such. The estimation process yields 2 estimated relationships - one explaining the effect of hatchery releases on expected adult production, another explaining the effects of the hatchery releases on the standard deviation of adult production. The standard deviation of adult production increases with the square of the number of seaward migrants both for Hokkaido chum salmon Oncorhynchus keta and for Oregon coho salmon O. kisutch. -from Authors
