Pink and Chum Exploitation Rate Model for Area 3, 4, and 5.

A large amount of time and resources are expended each year by Fisheries and Oceans Canada (DFO), Pacific Salmon Commission (PSC), First Nations, stewardship groups, Pacific Salmon Foundation (PSF) and other NGOs to obtain the catch and escapement data needed to monitor trends for BC salmon stocks and Conservation Units (CUs). A large portion of these data are available in DFO databases (e.g. NuSEDS and FOS). For many North and Central Coast (NCC) salmon stocks, these data have been combined in models to derive estimates of run size and exploitation rates for specific salmon indicator stocks (Alexander et al. 2010, English et al. 2016). The purpose of the report is to provide more comprehensive documentation for the Area 3-5 Pink and Chum Model previously described in English et al. (2012; 2014; 2016) and the recent enhancements made to re-program and streamline the data updating process for this model using R code.
