Data Exchange Description
The Columbia River Basin Coordinated Assessment Data Exchange (CAX) allows for efficient, consistent, and transparent data-sharing among the co-managers (fish and wildlife agencies and Tribes), regulatory agencies, and data consumers in the Columbia River Basin (CRB) for anadromous fish-related data. Development of the CAX was coordinated by the Washington Department of Fish and Wildlife and the Pacific Northwest Aquatic Monitoring Partnership with support from the Pacific States Marine Fisheries Commission’s StreamNet project.
The CAX supports the exchange of four salmon and steelhead population indicators including natural origin spawner abundance, natural origin smolt to adult return rate, and natural origin recruits (adult and juvenile) per spawner. It is envisioned that over time, the CAX will be expanded to include most of the indicators of highest importance to fisheries management and restoration decision makers.
The CAX schema and supporting flow documentation have been approved for use on the Exchange Network. Implementation resources for the most recent version follow.
