Description: For information or questions on shellfish area classifications contact the Connecticut Department of Agriculture, Bureau of Aquaculture (DA/BA). Mailing address: P.O. Box 97, Milford, CT, 06460, USA. Voice: 203-874-0696. Fax: 203-783-9976. E-mail: dept.agriculture@snet.net. Final authority for the classification of any shellfish area rests with the DA/BA. One of a set of three 1:24,000-scale datalayers that represent the classifications of shellfish growing waters for the State of Connecticut shoreline towns. This datalayer is composed of polygon features. The shellfishing areas are delineated and classified by the DA/BA, which is the state shellfish control authority in Connecticut. The Connecticut Department of Environmental Protection (DEP) applied information from the DA/BA to the hydrography data to create digital data of shellfish area classifications. DA/BA reassesses pollution sources and shellfish growing areas annually. The digital data is current to that effective date or last amended date recorded on the assessment date list (see supplemental information). This data is subject to change and the DA/BA may have more recent information for some areas. The three classification datalayers are feature based. Waterbodies, such as rivers and lakes and ponds, that appear as area features in the hydrography datalayer are classified in the Shellfish Area polygon shapefile. Smaller water bodies, such as streams and creeks, that appear as line features in the hydrography datalayer are classified in the Shellfish Area line shapefile. A separate point shapefile contains the marinas that are classified by DA/BA. Contact DA/BA or local health departments for additional information regarding the classification of marinas and anchorage areas. Three additional datalayers add to the classification picture. Markers, such as buoys, demarcation signs and piers, are referred to in DA/BA text describing the shellfish area classifications. The town boundary lines as depicted on DA/BA oyster/shellfish ground charts extend to the Connecticut/New York mid-Long Island Sound boundary line. The jurisdiction line on the charts indicates the boundary between state and town jurisdictional control over shellfish grounds. The jurisdiction line is separate from the shellfishing area classifications. *Please note that in some cases the town boundary line and the shellfish jurisdiction line are different and are so noted.Connecticut Department of Agriculture Bureau of Aquaculture classifies all tidal waters of Long Island Sound located along the coast of Connecticut. All shellfish growing areas are classified in accordance with the National Shellfish Sanitation Proram Model Ordinance (NSSP-MO). These classifications, established to minimize health risks, may restrict the taking and use of shellfish from some areas. No fresh water areas are classified for the harvesting of shellfish. Any shellfish area, regardless of classification, may be temporarily closed to all activities when a potential public health emergency exists as a result of a storm event, flooding, sewage, chemical, or petroleum discharges, or a hazardous algal bloom.APPROVED AREA:Is a classification used to identify a growing area that is safe for the direct marketing or consumption of shellfish. An area may be classified as Approved when a sanitary survey finds that there is no contamination from pathogenic organisms, poisonous or deleterious substances, marine biotoxins, or bacteria concentrations exceeding the bacteriological standards for a growing area in this classification as set forth in the NSSP MO. The water quality in the growing area shall also meet the bacteriological standards for an Approved classification.CONDITIONALLY APPROVED AREA:Is a classification used to identify a growing area that is safe for the direct, marketing or consumption of shellfish when the area is in the open status. The area must meet the criteria for Approved classification when the area is in the open status, and meets the criteria for the restricted classification in the closed status. An area may be classified as Conditionally Approved when a sanitary survey finds that the area can remain in the open status for a reasonable period of time, the factors impacting the area are known and predictable and do not preclude a reasonable management approach, and the water quality correlates with the environmental conditions or other factors affecting the distribution of pollutants into the growing area. Each Conditionally Approved growing area must have a written management plan that is adhered to by all responsible parties. CONDITIONALLY APPROVED SEASONAL AREA:Is a classification used to identify a growing area that is safe for the direct, marketing or consumption of shellfish when the area is in the open status. The area must meet the criteria for Approved classification when the area is in the open status, and meets the criteria for the restricted classification in the closed status. An area may be classified as Conditionally Approved when a sanitary survey finds that the area can remain in the open status for a reasonable period of time, the factors impacting the area are known and predictable and do not preclude a reasonable management approach, and the water quality correlates with the environmental conditions or other factors affecting the distribution of pollutants into the growing area. Each Conditionally Approved growing area must have a written management plan that is adhered to by all responsible parties. Conditionally Approved Seasonal areas are closed under certain seasonal conditions, either due to the operations of marinas or mooring fields, or because the area may be subject to elevated bacteria levels during certain times of the year. CONDITIONALLY RESTRICTED: Is a classification used to identify a growing area where a sanitary survey has found that the area meets the criteria for Restricted classification when the area is in the open status and meets the criteria for Prohibited classification when the area is in the closed status. Each Conditionally Restricted growing area must have a written management plan that designates whether harvested shellfish are relayed or depurated. Shellfish may only be harvested from Conditionally Restricted areas by special license, and may not be directly harvested for market or consumption.PROHIBITED:Is a classification used to identify a growing area where there has been no current sanitary survey or where a sanitary survey has found that the area is adjacent to a sewage treatment plant or other point source outfall with public health significance; pollution sources may unpredictably contaminate the growing area; the growing area is contaminated with fecal waste so that the shellfish may be vectors for disease microorganisms; and/or that the concentration of biotoxin is sufficient to cause a public health risk. Shellfish may not be harvested from Prohibited areas except for seed oystering or depletion of the areas.
