Description    


The project supports three separate approaches to monitoring Skagit Chinook abundance, run timing, escapement, and impacts to Chinook stocks in different terminal fisheries. These efforts are intended to support the data collection needed to effectively manage fisheries to monitor ESA recovery goal expectations. The three separate actions include terminal test fisheries, spawning ground surveys, and tribal catch sampling (biological sampling, mark status sampling including CWT analysis). Test fisheries are conducted in the Skagit River, at one location once per week from June to end of July. Standardizing test fishery catch effort by area, time, and gear provide an effective method for monitoring Chinook recovery implementation. Spawner surveys which consist of redd and carcass counts are conducted in tributaries of the Skagit and Skagit mainstem to monitor escapement for the three summer and fall stocks. These surveys start in September and run through November and provide information for estimating escapement estimates, indicator stock production, and biological age information. The Natural Resources staff plan on expanding spawning ground surveys with this support to include spawning ground surveys and biological sampling in the Skagit River above Newhalem and into the Seattle City Light’s by-pass (from Gorge Dam to Newhalem power house) reach due to ongoing concerns about the hydropower operations on Chinook and other treaty fishery resources. The third component this program supports is catch sampling of tribal fisheries. Tribal fisheries are monitored and sampled from May through November when Chinook interceptions are most likely to occur. These funds support a portion of one biologist and three fish technicians.

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.
