Collective navigation during the spawning migrations of Pacific salmon

Project Description

This project seeks to understand the role of social interactions and collective behavior to influence patterns of homing and straying in Pacific salmonids and expands on ideas illuminated in the review of collective navigation in salmon led by Andrew Berdahl (Omidyar Fellow at the Santa Fe Institute) and Peter Westley, recently published in Fish and Fisheries.
