Abstract

The data and scripts contained within this repository allow for the reproduction of the analyses described in the manuscript "Using lower river genetic stock identification (GSI) and a tributary-specific mark-recapture program to estimate genetic unit escapements of Pacific Salmon within large river systems", an escapement estimation approach that combines lower river genetic stock identification (GSI) with an accurate mark-recapture escapement estimate for a single major spawning tributary (the “reference unit”), with the example under investigation being the Skeena River coho salmon, the Skeena River Tyee test fishery, and the Witset Mark-Recapture program on the Bulkley River. This repository is organized into two pieces. First, a folder containing the genetic data used underlying the methods (Baseline, mixtures, and Colony assignments as made). Second, a folder containing the R scripts used in executing the analyses.
