Excerpt from Possible Management Procedures for Increasing Production of Sockeye Salmon Smolts in the Naknek River System, Bristol Bay, Alaska

In freshwater, juvenile sockeye salmon typically occupy four successive habitats for varying periods: spawning gravels of streams or lake beaches for several months, littoral of lakes for a few weeks, Open water areas of the lakes for several months to 2 or 3 yr, and an outlet river through which the smolts travel for a few hours or days to reach the ocean. Two factors seem most likely to limit the production of smolts: the quan tity and quality of spawning grounds, which may limit the number of fry produced, and the productivity of the pelagic waters of the lakes where juvenile salmon do most of their feeding and growing.
