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.

Paperback. Condition: New. Print on Demand. This book takes a unique look at the ecology of one of the world's most productive ecosystems: the Naknek River system of Bristol Bay, Alaska. The author provides a comprehensive analysis of the system, from its physical aspects and productivity of lakes to the abundance of juvenile sockeye salmon and associated species. The author also explores factors that appear to be limiting production of juvenile sockeye salmon in the system, and suggests several management procedures that might significantly increase the production of smolts, ultimately increasing the yield of adult sockeye salmon to the fishery. This book will be of interest to fisheries scientists, ecologists, and natural resource managers. It provides a wealth of information on the Naknek River system and its sockeye salmon population, and offers valuable insights into the management of this important fishery resource.
