Overabundance of salmon, combined with effects of recent marine heat waves, may have been responsible for unexpectedly low returns of all five species of Pacific salmon across the North Pacific in 2020?

Click Here to read Review of the Central Valley Angler Survey by West Inc., Enviromental & Statistical Consultants. Summary: Inland sport harvest of Chinook salmon in California’s Central Valley (CV) streams comprises a significant proportion of the total escapement. The CV angler harvest survey, reinitiated in 2007, is a long-term monitoring program designed to develop annual estimates of total angler effort and in-river harvest of sport fish from the Sacramento River and major tributaries. In addition to Chinook salmon, the survey includes a number of other species considered to have recreational value. As described in Titus et al. (2009), the key objectives of the CV angler survey specific to Chinook salmon are:
- Analysis and reporting of angler effort and harvest,
- Estimating the contribution of hatchery Chinook in the CV sport harvest, and
- Estimating the age structure of Chinook salmon and steelhead in the CV sport harvest.
Estimates of Chinook salmon harvest in the recreational fishery are used by the Pacific Fishery Management Council to help determine ocean harvest quotas off the coasts of California, Oregon and Washington (Titus et al. 2009).
This document reviews the existing angler survey design and analysis techniques used in the CV for estimating Chinook salmon angler effort and harvest (Titus et al. 2009). After describing the current angler survey protocol, we provide recommendations for future surveys and analyses of those survey data. The recommended methods will allow for estimation of precision (e.g., confidence interval [CI]), and are expected to reduce bias and improve precision of estimates of Chinook salmon angler effort and harvest in the CV.
