Icon for White Sturgeon Upcoming HLI webpageColumbia River Basin sturgeon managers engaged in the StreamNet Executive Committee have indicated it would be valuable to shared standardized HLIs through the Coordinated Assessments Partnership (CAP). StreamNet and the CAP Core Team are tasked, as resources permit work to advance, to conduct a scoping exercise for a White Sturgeon abundance indicator, similar to natural-origin spawner abundance (NOSA) for salmon and steelhead.

Background

The Five-Year Plan for the Coordinated Assessments Partnership outlines an approach for conducting a scoping exercise to inform development of a White Sturgeon abundance indicator. This approach consists of these steps:

  1. Further definition is needed before proceeding to development. Once this is completed, the proponents of this indicator will describe the purpose of this indicator and how it would be used at a meeting of the StreamNet Executive Committee.
  2. If directed to proceed by the StreamNet Executive Committee, StreamNet and the CAP Core Team will request the assistance of the PNAMP Fish Monitoring Workgroup (FMWG) to facilitate a broader discussion with relevant experts in the Basin to scope out this topic. This discussion should inform what content/data would be available to support this indicator and agreement on methods to calculate this indicator.
  3. PSMFC StreamNet staff will convene a core group of the CAP Data Exchange Standard (DES) Development Team to scope a draft, general outline, of a DES table for the white sturgeon indicator.
  4. StreamNet and the CAP Core Team will then convene a small group of fisheries managers to discuss and report back to the StreamNet Executive Committee and seek their approval to go forward. If approved, the Fish Monitoring Workgroup and the CAP DES Development Team will develop and finalize the DES table for this indicator.

The 2020 Addendum to the NPCC Columbia River Basin Fish and Wildlife Program also identifies a regional need for tracking progress towards meeting White Sturgeon biological objectives for abundance (objective WS1), spatial distribution (objective WS2), genetic diversity (objective WS3), and productivity (objective WS4) derived from sturgeon management plans across the region. The NPCC states that contributing to achieving these White Sturgeon adult abundance targets, as well as other population characteristics, serves in the absence of quantitative goals and objectives based in hydropower loss assessments.

Revised version of the Five-Year Plan for the Coordinated Assessments Partnership adopted in 2019 and revised in 2021 during the September 9, 2021 Executive Committee meeting. This updated version of the plan describes the hatchery indicator work that is ongoing through the HCAX project, updates the approach for adding new content about the available of data for salmon and steelhead populations without CAP Fish HLIs and /or trends data, and updates the CRITFC ITMD project description.
