Bird Distribution and Abundance - Ocean Survival of Salmonids
|
A study to evaluate the role of changing ocean conditions on growth and survival of
juvenile salmon from the Columbia River basin as they enter the Columbia River plume
and Pacific Northwest coastal habitats. Adult returns vary dramatically (over 10 fold)
as a result of changing (good or bad) ocean conditions juveniles experience. Evaluating
the benefit of restoration efforts in the Columbia River to restore endangered salmon
populations needs to consider ocean conditions as a contributing factor to recovery.
This is a large collaborative project with contributions from NWFSC, Oregon State
University, and Oregon Health and Science University.
The work focuses on three objectives:
1) Determining the distribution, growth, and condition of juvenile Columbia River
Chinook and coho salmon in the plume and their ocean environments with associated
physical and biological features, and effects on salmon survival via regular spring
and summer surveys.
2) Using additional focused surveys to obtain critical pieces of information on predator
impacts, specific food resources, biological condition, and means by which juvenile
salmon exit the Columbia River estuary.
3) Synthesizing the early ocean ecology of juvenile Columbia River Chinook and coho
salmon, test mechanisms that control salmonid growth and survival, and produce ecological
indices that forecast salmonid survival.
This project provides critical information on marine survival to the Columbia River
salmonid management community (hydrosystem, harvest, hatchery, and habitat management)
provides environmental indicators useful for forecasting salmon returns, and provides
a greater understanding of ecological controls on salmon populations. This is a long-term
monitoring and research project initiated in 1998.
