Hatchery, predation, and climate effects on productivity of wild Chinook, Coho, and Chum salmon

This paper presents a Bayesian hierarchical approach for developing and comparing performance of multipopulation spawner-recruitment models that estimate potential hatchery, predation, and/or environmental covariates effects on wild productivity for Chinook, Coho, and Chum populations in British Columbia. We investigate wild salmon productivity relationships with multiple covariates using multi-population Ricker models fit with spawner-recruit time series from 1954-2015 for 23 Coho conservations units (CUs), 1986-2013 for 24 Chinook populations (8 stocks, 16 CUs), and 1973-2013 for 28 Chum CUs.
