Coastal State Discussion March 29 | Can Winter Flounder Survive Warmer Temperatures?


Winter flounder dominated commercial and recreational fishing in Narragansett Bay until the 1980s. Populations have since declined to historically low levels. This has raised concerns about what caused this decline, the overall health of the bay, and the future for fisheries in the bay.

Overfishing and predation may be a few reasons why, but new studies suggest warming water temperatures may also be crippling populations.

Joe Langan, a Ph.D. candidate, and Dr. Jeremy Collie at the University of Rhode Island’s Graduate School of Oceanography (GSO) have been investigating the role temperature plays in winter flounder populations. Their primary focus has been looking at which life stages of winter flounder are most vulnerable.

Langan will share research findings Thursday, March 29 at the Coastal Institute Auditorium on the University of Rhode Island’s Bay Campus from 4:30 to 6 p.m. as part of Rhode Island Sea Grant’s annual Coastal State Discussion Series.

This project aims to help resource managers identify which habitats to then protect in order to sustain a winter flounder population in Narragansett Bay. The results could also be useful for other winter flounder populations and in identifying the mechanisms of population regulation in a marine fish species.

When: Thursday, March 29
Where: Coastal Institute Auditorium, URI Narragansett Bay Campus
Time: 4:30-6 p.m.

Please RSVP as light refreshments will be served. Light refreshments will be served.

The Coastal State Discussion Series is a free event open to the public. This series is dedicated to highlighting current scientific research focused on Rhode Island’s coastal and marine resources impacting coastal communities and environments.

This series is sponsored by Rhode Island Sea Grant with the support of the Coastal Institute at the University of Rhode Island, the URI College of the Environment and Life Sciences, and the URI Graduate School of Oceanography.
