Shellfish Harvesting Area Closure Alerts
For your convenience, the below active alert box is used to distribute information on water quality-related shellfish harvesting closures of Conditional Areas and emergency closures from harmful algal blooms, sewage releases, etc.
A link to a reference map and written descriptions of all RI shellfish waters with seasonal and year-round water quality related shellfish harvesting closures are provided below.
As required by RI General Law § 20-8.1-3 DEM will continue to use the 24-hour shellfish hotline (401-222-2900) as the primary tool for providing notice of harvesting restrictions.
Information regarding shellfish management restrictions, minimum sizes, and possession limits: Shellfish & Regulations.
Where Can I Shellfish?
The DEM Shellfish Program classifies all shellfish harvest waters within the limits of Rhode Island state waters for the enjoyment of recreational shellfish harvesters and for the commercial shellfish industry. Click the map image below to view the approximate boundaries and the current classification of these areas.
The boundaries shown on these maps are a general reference only. The written description of each classified area supersedes these map depictions and can be found by following the identified links within the map or in the document entitled Shellfish Grounds, Closures and Approved Areas
All waters of the state that are designated for shellfish harvesting have been identified and named as individual Growing Areas (GA1 – GA 17) with area specific classifications and boundaries.
Maps and descriptions of the individual shellfish growing areas and their current classifications can also be found here:

The State of Rhode Island is a member of the Interstate Shellfish Sanitation Conference. The Interstate Shellfish Sanitation Conference (ISSC) was formed in 1982 to foster and promote shellfish sanitation through the cooperation of state and federal control agencies, the shellfish industry, and the academic community. Rhode Island must abide by rules and guidance set forth in the National Shellfish Sanitation Program's (NSSP) Model Ordinance in order to operate as an interstate shellfish state.Other Important Information
- In addition to pollution closures both recreational and commercial shellfish harvesters need to be aware of DEM Division of Marine Fisheries management and catch regulations. DEM Division of Marine Fisheries sets size, quantity, and seasonal harvesting limits and has designated areas in approved shellfish harvesting waters that have additional management limitations. Refer to their recreational and commercial fishing laws for the complete text of these regulations.
- Always remember shellfish harvesting will be allowed only when declared OPEN by the DEM Office of Water Resources based upon water quality considerations.
- Regulations and notices of Polluted Shellfish Grounds by the Office of Water Resources shall supersede the regulations cited above.
- DEM's Division of Law Enforcement Marine Unit provides patrol and enforcement of the shellfish growing area classifications and boundaries and information on this element of the sanitary control of the shellfish industry along with other marine enforcement duties.
Shellfish Wholesalers and Dealers
The state annually issues numbered certificates to shellfish dealers who comply with the agreed-upon sanitary standards & forwards copies of the interstate certificates to the U.S. Food and Drug Administration. The FDA makes an annual review of each state shellfish control program, including the inspection of a representative number of shellfish processing plants & publishes a list of valid interstate shellfish shipper certificates. View Rhode Island Department of Health's shellfish inspection program information.
