Spawner-recruit relationship of Chinook salmon in the Kuskokwim River drainage

Project Description

Understanding the impact of environmental conditions and variability in biotic and abiotic factors on estimates of abundance and survival of Kuskokwim River Chinook salmon is important for forecasting abundance. Our study objectives are to: (1) describe potential environment-recruit relationships by incorporating environmental variables into a spawner-recruit model; and (2) identify deficiencies in environmental and life-history information needed for improvement of this model. These objectives will be met by using the Kuskokwim River Chinook salmon spawner-recruit model currently being developed through an Arctic-Yukon-Kuskokwim Sustainable Salmon Initiative project (SSSF Project 45554). By understanding the environment-recruit relationship and improving our ability to forecast abundance, our project will allow the development of appropriate, science-based escapement goals and strategies for the management of Chinook salmon in the Kuskokwim River drainage.
