Since 2015, the Coordinated Assessments Partnership (CAP) has recognized the importance of creating access to standardized hatchery fish indicators and metrics for informing regional assessments and reporting needs. CAP will be tackling hatchery fish/hatchery program data, focusing on the goals and tasks outlined in the Pacific Northwest HCAX proposal funded by the Environmental Protection Agency (EPA) for 2020-2023. The data sharing achieved through the Pacific Northwest HCAX project will inform decisions and reporting requirements that relate to both ESA-listed and non-listed salmon and steelhead, as well as other species that rely on these fish as prey resources.


The intent to develop hatchery indicators has been of regional interest since 2015. The 2015 Five-Year Plan for the Coordinated Assessments Partnership outlined a multi-step approach to develop and implement the sharing of standardized hatchery fish indicators, consisting of:

  1. The StreamNet Executive Committee will assess currently available data, hatchery data needs, etc., before hatchery indicator development proceeds. Alignment with regional hatchery data needs will be ensured through discussion with hatchery data users and current hatchery database managers. Development should include identifying a target that needs regionally standardized data, identifying data category(ies) and focus of next regional data standardization under CAP; involve the right people, form a DES group.
  2. Continue development of hatchery indicators, assess available data, begin to populate hatchery indicators, coordinate closely with hatchery database managers.
  3. Finalize and adopt hatchery indicators. Begin to populate adopted hatchery indicators with data.
  4. Review hatchery data and flow, and assess data availability, critical gaps, relationships to regional data needs, etc., for the CAP project. Review will include recommendations on data collection effort (i.e., more or less data collection needed for certain indicators).
  5. Maintain automated flow of hatchery indicators and continue to populate and update adopted indicators with data. Implement recommendations of performance reviews in data collection efforts.

In the 2015 version of the Five-Year Plan for the Coordinated Assessments Partnership, seven draft hatchery indicators were proposed as a starting place: smolt-to-adult return rate (SAR); adult recruits per spawner (R/S); number of fish spawned; proportion of hatchery broodstock that are natural-origin fish; egg take; proportionate natural influence (PNI) of supplementation hatcheries; and egg to release survival rates for hatchery programs.

In 2017, an initial effort was started with the development of a draft data exchange standard for five indicators: number of fish spawned, proportion of natural-origin broodstock, egg take, SAR, and R/S. Lack of funding prevented further work at that time.

In 2020, the CAP Core Team developed a proposal to fund development and initiate sharing of hatchery indicators, titled Salmonid Hatchery Information for Regional Decision-Making Through the Hatchery Coordinated Assessments Exchange (Pacific Northwest HCAX). The proposal submitted by WA RCO/GSRO, WDFW, Colville Tribes, PNAMP, and StreamNet was selected for funding through an EPA Exchange Network Grant. Work will take place from 2021 to 2023 and will leverage existing partner work and past CAP work. The HCAX project process will enable interested partners to engage in a collaborative process to identify and share key salmon and steelhead hatchery HLIs and achieve the following outcomes:

  1. Advance sharing of standardized HLIs and metrics for hatchery salmon and steelhead in a well-defined, transparent manner across the Pacific Northwest
  2. Improve consistency in the information communicated with the public and that used for environmental reporting required by and for regional decision-making in multiple forums
  3. Support and contribute to reporting on salmon and steelhead for states, tribes, tribal consortia, federal agencies, and other partners

The following is a brief overview of the HCAX project tasks and timeline, facilitated by PNAMP:

Nov — Dec 2020: Identify participants for two working groups, Biologists and Data Managers
Jan 2021 — Mar 2021: Identify appropriate hatchery HLIs to share regionally
Mar 2021: Workshop 1 to discuss and confirm HLIs
Apr 2021 — Aug 2021: Agree on definitions and create controlled vocabulary
Sep 2021 — Jan 2022: Develop data-sharing rules and procedures
Mar 2022: Workshop 2 to review progress toward data exchange standard
Apr 2022 — Sep 2022: Refine data exchange standard, develop schema, develop and test flow configurations

Five-Year Plan for the Coordinated Assessments Partnership adopted 20190731 (revised 9Sept2021)

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.

Recommendations for Broad Scale Monitoring to Evaluate the effects of Hatchery Supplementation on the Fitness of Natural salmon and Steelhead Populations

Final Draft Report of the Ad Hoc Supplementation Monitoring and Evaluation Workgroup (AHSWG). AHSWG has focused its efforts on designing recommendations for monitoring which will help predict the magnitude of change to abundance and productivity in supplemented natural populations that can be attributable to hatchery influence. Building off the previous Supplementation M&E Workshops and the work of CSMEP, the AHSWG provides  comments and recommendations for M&E of supplementation programs, which will enable a regional assessment of supplementation effects on natural salmon/steelhead populations.
