A quantitative life-cycle model to identify research priorities and test management strategies for the Mackenzie River broad whitefish, Coregonus nasus Pallus
Effective management of the Mackenzie River broad whitefish (Coregonus nasus Pallus) requires detailed knowledge of life history and an overall understanding of the dynamics of the system. I propose a simulation modeling framework for analyzing the life cycle of the broad whitefish and for identifyi...
