To the Sea and Back! A lecture by Ciaran Shaughnessy

Come listen to Ciaran Shaughnessy’s lecture: “To the sea and back: why a freshwater fish wanders into the ocean and how it finds its way home.” This talk will discuss current hypotheses on the unanswered question “How did anadromy evolve?” and provide a general overview of the physiological drivers that propel fish to migrate to the ocean and eventually guide them back home to the river. Ciaran grew up in Maine, making frequent use of the many paddling, swimming, and fishing opportunities along the Presumpscot River, and is now a research biologist at the University of Massachusetts studying migratory fishes. And afterwards, we will drive to Mill Brook to see the Alewife run!
