Ocean Harvest Real-Time Forecasts of Fall Chinook Salmon (Oncorhynchus tshawytscha) Returns to the Columbia River

Apr 24, 2009

Abstract

Forecasts of fall Chinook salmon runs to the Columbia River are a critical management component for harvest decisions and monitoring abundance trends because Columbia River fall Chinook salmon form the largest contributing fish group to ocean Chinook fisheries north of Cape Falcon, Oregon, and also they include Snake River fish at extinction risk (Good et al. 2005). For the forecast importance, preseason forecasts of fall Chinook salmon runs have been made annually, using historical sibling runs. However their accuracy has not been consistent over years, and further uncertainty of preseason forecasts has not been measured.
