Oceanographic Trawl Data - Juvenile Salmon & Ocean Ecosystem Survey
FY20 will mark the 23nd year of sampling, making the Juvenile Salmon and Ocean Ecosystem Survey (JSOES) the longest running salmon survey on the west coast. JSOES has clearly demonstrated correlations between ocean conditions and the distribution, abundance, and survival of juvenile Columbia River (CR) salmon in the Northern California Current (NCC) nearshore ecosystem. For example, our ocean indicators provide managers from the federal and state governments, tribes, and other agencies/groups the ability to forecast adult returns one to two years in advance for coho and spring/summer Chinook salmon. We continue to show the importance of evaluating ocean conditions to support management decisions and to provide context for efforts by the Northwest Power and Conservation Council (NWPCC) and BPA to restore and enhance salmon production.
The primary goal of our work is to develop a mechanistic understanding of how trophic dynamics and conditions in the ocean and CR plume affect survival of juvenile salmonids. This knowledge will allow us to improve forecasts in a quantitative rather than qualitative manner, and decouple the effects of mitigation efforts in the freshwater environment from the effects of a changing ocean environment. These improved forecasts will lead to well-informed recommendations for an ecosystem approach to management strategies based on the full suite of river, plume, and ocean environments.
