José Antonio Fernández Robledo, senior research scientist at Bigelow Laboratory for Ocean Sciences, will discuss the diseases facing mollusks in local waters. From ‘Dermo’ disease in the eastern oyster to a contagious cancer affecting soft-shell clams, Robledo will discuss how they are being affected by these diseases as well as what is being done to prevent them and what we can learn from them. The event will be held at the Rockport Public Library Wednesday, Aug. 24 at 6:30 p.m. This is an in-person event, and it is free and open to all.
