The primary objective of this trans-generational genetic mark-recapture (tGMR) project is to: 1) estimate the abundance of Chinook salmon spawners and effective breeders in the Stillaguamish River above the smolt trap site using genetic abundance methods.

Jolly-Seber method, carcass mark-recapture using the Petersen method, a redd count based estimate assuming one redd per female, and a redd count based estimate using a redd-area method. A logistic regression model was developed to distinguish Chinook salmon from coho salmon redds for those redds which did not have a known associated.

The Skeena River is host to the second largest aggregate of Chinook salmon in British Columbia. While the aggregate is a PSC escapement indicator stock, there are no biologically based escapement goals for this population.

Most reviews of salmonid escapement estimation techniques have been based on logistical considerations or site-specific applications and not on statistical first principles. We reviewed six categories of salmon escapement techniques: area-under-the-curve, carcass abundance, mark-recapture, passage count, peak count, and redd count methods, based on statistical accuracy Cited by: a mark-recapture method to estimate the abundance of sablefish in Chatham Strait.
