Symposium 34

The proceedings of the 2001 conference “Restoring Nutrients to Salmonid Ecosystems” and the first book of its kind in the scientific and technical market, this volume presents recent information on the role and importance of marine-derived nutrients in salmonid ecosystems. The authors examine how this research can be used effectively to assist in rebuilding salmonid stocks in the Pacific Northwest.

This book covers:

(1) Description and management of historical and current nutrient regimes in salmonid ecosystems

(2) Ecological linkages between salmon and productivity of freshwater ecosystems and the ecological impacts of a diminished salmon nutrient shadow

(3) Dispersal mechanisms of marine-derived nutrients in Pacific Northwestern freshwater ecosystems

(4) Effects of hatcheries, harvest, and other resource management regimes on nutrients and their dispersal

(5) Incorporation of nutrient management into ecosystem restoration
