Molluscan Shellfish Applications, Forms, and Licenses

Commercial, Municipal, and Special Study-related licenses can be found below. Connecticut General Statute Section 26-192c requires each commercial harvester, producer or shipper of shellfish to obtain a license from the Department of Agriculture, Bureau of Aquaculture (DoAG). The license describes the type of operation authorized, and in some cases the specific areas involved.

Recreational shellfishing licenses are handled by each municipality and may or may not be required. Municipalities may also require a commercial shellfishing license for waters under local jurisdiction.

Please be aware there may be 
other permits needed for an Aquaculture business along with HACCP information and forms that should be referenced. Licenses are valid for one year (July 1-June 30) or for the duration of the activity, if less than one year. They are not transferrable and must be renewed annually. Licenses must be available and presented when requested by the DoAG or Department of Energy and Environmental Protection (DEEP) enforcement officers.
