Collective Behavior

The migrations of salmon are one of the great wonders of the natural world. To date, most of our understanding of how and why salmon migrate has been focused on individuals, despite knowing that salmon move in groups. Recently, members of the SEEC Lab have been at the leading edge to show that social interactions between individuals likely plays a fundamental role in the homeward and seaward migration in anadromous salmonids.
