Chinook Salmon Research Initiative
Yukon River Chinook Salmon

Juvenile Salmon Abundance

Project Summary

Project Name:

Yukon River Juvenile Chinook Salmon Abundance


Long term monitoring of juvenile Yukon Chinook salmon abundance and ecology in the Northern Bering Sea can improve our understanding of factors affecting early marine survival, growth, and may improve run forecasts. Abundance indices for juvenile Yukon Chinook salmon have been estimated since 2002 (excluding 2008) by NOAA from surveys employing large vessels and large pelagic trawls. In this project NOAA and ADF&G are teaming up to calibrate juvenile Chinook salmon abundance indices from these large trawl platforms to a smaller and more economical survey platform, enabling long-term sustainability of these surveys and continuity of these important data.
