The project began in June 2019 and was supported through July 2020. This award supports Upper Skagit Indian Tribe (USIT) with their ongoing Skagit adult Chinook monitoring program. The Tribe considers this work as the foundation of tracking Skagit Chinook Recovery implementation under the Endangered Species Act. The project focuses on three separate projects that monitor Chinook adult returns to the Skagit River. Data is collected on timing, abundance, and spatial distribution on all six independent stocks of Skagit Chinook. USIT Natural Resources Department (NRD) staff collect data on Skagit adult Chinook via test fisheries, catch sampling and spawning ground surveys.
In this award the Tribe was able to complete one full year and the start of the second year of monitoring chinook by-catch, in a standardized test fishery on the Skagit River. Although the test is designed to target Sockeye for the development of a future in season update model, it also affords a standardized effort to monitor chinook encounters that may shape future sockeye fisheries. All the chinook encountered in this test fishery were sampled at 100% for scale, size, sex and hatchery origin. In addition to the test fishery, this program enables a robust commercial sampling of USIT fisheries that encounter Chinook. Monitoring included the collection of biological samples (scale, sex, length) and tag (hatchery indicator stocks and out of basin strays), any CWT encountered was processed and rad and shared with basin co-managers. Lastly, field staff from the NRD were also able conducted one season of spawning grounds surveys for the both Skagit Chinook Summer and Falls.

Project Benefit    

Monitoring actions arise from need to evaluate the success of restoration, protection, hatchery and harvest actions in reaching recovery goals. The tribes’ programmatic monitoring program focuses on biological monitoring of returning adults at the basin scale. Three separate components are utilized to address the population viability assessment; test fisheries in the lower river, catch monitoring and sampling of all terminal fisheries, and spawning ground surveys. Chapter 16 Monitoring Actions in the Skagit Recovery Plan identifies these components and how data from these efforts are used for testing conditions and recovery assumptions. The data collected in these efforts are shared with basin co-managers to monitor fundamental population metrics for example but not limited to; the development of six independent population escapement estimates, timing and distribution of run, age composition data, hatchery and wild and CWT group composition of the run, population fitness, percent of juvenile life history strategy in adults, spawner recruit analysis, encounter rates, catch and harvest distribution between fisheries, and total exploitation rates. Age and CWT information is needed annually to monitor fishery management objectives, without these funds this critical information would lag years behind the need to shape international, national, and terminal fisheries on annual return year basis.
