Welcome to the Bureau of Aquaculture

9/7/23 - The DoAG issued a precautionary closure of the Groton Approved area due to elevated sample results. All harvesters implemented a voluntary recall and no product from the area remains in the market. There have been no illnesses associated with the closure or recall, and this is in no way associated with Vibrio. Read the downloadable press release for more information.

8/18/2023 - Connecticut shellfish have never been associated with Vibrio vulnificus infections. Click this link for updated information.
