Recreational shellfish areas

CT Recreational Shellfish Beds

In Connecticut, shellfish are defined as oysters, clams, mussels and scallops; either shucked or in the shell, fresh or frozen, whole or in part. Undesignated Beds under town or state jurisdiction which are not currently designated as “Natural Bed” or leased, licensed or otherwise managed for commercial activity may be managed as “Recreational Beds” by the municipality, where water quality classification permits. These beds may or may not sustain natural shellfish populations.

Commercial aquaculture locations

CT Natural Shellfish Beds

In Connecticut, shellfish are defined as oysters, clams, mussels and scallops; either shucked or in the shell, fresh or frozen, whole or in part. Natural beds get their name from the fact that shellfish, especially oysters, naturally inhabited the area. Natural beds have specific regulations concerning their use. Use of the natural beds requires a Relay/Transplant License I or II and/or Seed Oyster Harvesting License. These beds cannot be leased or subdivided; they are to remain open to any properly licensed shellfisherman.

CT Aquaculture Operations

The approximate locations of "Certificate for Aquaculture Operation" permitted facilities/gear via the State of Connecticut Application for Joint Programmatic General Permit (PGP) for Aquaculture Department of the Army General Permit. Permitted projects have undergone review by the State of Connecticut Department of Agriculture Bureau of Aquaculture, the U.S. Army Corps of Engineers New England District, and the Connecticut Department of Energy and Environmental Protection.

CT Seaweed Licenses

Areas where the Department of Agriculture Bureau of Aquaculture issues non-transferable licenses for the planting and cultivating of seaweed.

CT Aquaculture Gear Areas

The approximate geographical location of "Certificate for Aquaculture Operation" permitted gear via the State of Connecticut Application for Joint Programmatic General Permit (PGP) for Aquaculture Department of the Army General Permit. Permitted projects have undergone review by the State of Connecticut Department of Agriculture Bureau of Aquaculture, the U.S. Army Corps of Engineers New England District, and the Connecticut Department of Energy and Environmental Protection.

CT State Shellfish Lease Beds

In Connecticut, shellfish are defined as oysters, clams, mussels and scallops; either shucked or in the shell, fresh or frozen, whole or in part. In 1881 a line was established that divides the waters of the state into a northern and southern section. All beds south of this line are State beds.

CT Town Shellfish Lease Beds

In Connecticut, shellfish are defined as oysters, clams, mussels and scallops; either shucked or in the shell, fresh or frozen, whole or in part. In 1881 the Commissioners line was established that divides the waters of the state into a northern and southern section. Most beds north of this line are town beds except for beds north of the line in Milford, West Haven, and New Haven. Town beds are under town jurisdiction and may be leased, licensed or otherwise managed through the local shellfish commission.
