It is referenced here to clarify that in some cases the town boundary lines of the Shellfish Area Town Poly layer and the Shellfish Bed Jurisdiction layer are different and are so noted. General Information Applicable to Shellfish Classifications Datalayers: 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 shellfish datalayers that can be used together as a group include Shellfish Area Classification Line, Shellfish Area Classification Poly, Shellfish Area Marina, Shellfish Area Marker, Shellfish Area Town Poly, Shellfish Area Town Line, Shellfish Bed Jurisdiction, and Connecticut Managed Shellfish Beds.

To protect public health from contaminated shellfish, primarily due to harmful pathogens, state agencies regulate where shellfish can and cannot be harvested for direct human consumption. The status of shellfishing areas serves as an indicator of public health conditions in the Bay. This vector dataset contains shellfishing area classifications for 2020 in the Narragansett Bay, Little Narragansett Bay, and Southwest Coastal ponds. Using data from the Massachusetts Division of Marine Fisheries (MADMF), the Rhode Island Department of Environmental Management (RIDEM), and the Connecticut Department of Agriculture, Bureau of Aquaculture (CTDABA), The Narragansett Bay Estuary Program defined three categories derived from the shellfish growing area classification systems used by Massachusetts and Rhode Island. In “Approved” areas, shellfish harvesting is allowed for direct human consumption all year round (some exceptions may apply). “Conditionally Approved” areas allow shellfish harvesting for direct human consumption with some restrictions, depending on each state’s shellfish program criteria. In “Prohibited” areas, shellfish harvesting is not allowed for direct human consumption. This dataset is intended for use in general planning, GIS analysis, and graphic display at watershed and subwatershed scales. For more information, please contact msorlien@nbep.org.

This data is a graphic representation of NJ coastal waters classified according to regulations of shellfish harvest. Waters are classified in one of five categories: Prohibited - harvest not allowed under any conditions. Special Restricted - harvest allowed with a special permit requiring further purification of the shellfish before sale. Seasonal (Nov - Apr) - and Seasonal (Jan - Apr) - where harvest is permitted only during certain seasons of the year. The final category is Approved - harvest permitted under any conditions. Classification of the waters is based on the National Shellfish Sanitation Program. As specified in this program, classifications are based on three components: 1) Regular monitoring of water quality 2) Field surveys of shoreline conditions 3) Study of water currents and flows (hydrography). These functions are performed by New Jersey's Bureau of Marine Water Monitoring which monitors about 2,500 locations a minimum of five times a year. Please note: Shellfish water classifications in this theme may be temporarily superseded by an emergency closure order. The Department may suspend harvest in areas impacted by an intermittent pollution episode or emergency condition when the event has or may have a deleterious impact on public health. Public notice will be provided of any emergency closures. However, if there are any questions about the suitability of a shellfish growing are for harvest, please contact the Bureau of Marine Water Monitoring at (609) 748-2000.

This data spatially represents report boundaries used to quantify and summarize water quality data collected within NJ coastal waters for the National Shellfish Sanitation Program (NSSP). The primary purpose of each reporting area is to comply with the guidelines of the NSSP that are established by the Interstate Shellfish Sanitation Conference (ISSC). Reports generated under this program form the basis for classifying shellfish waters for the purpose of harvesting shellfish for human consumption. As such, they provide a critical link in protecting human health. All water quality data along with Sanitary Surveys conducted within each report area boundary are reviewed and analyzed to validate and determine if NJ’s current shellfish classification statuses are accurate or in need of modification. This dataset will provide a link to the NSSP reports that are generated by the Bureau of Marine Water Monitoring.

This dataset is a line and a polygon feature-based layer compiled at 1:24,000 scale that includes water quality classification information for surface waters for all areas of the State of Connecticut. The Surface Water Quality Classifications and the Ground Water Quality Classifications are usually presented together as a depiction of water quality classifications in Connecticut. Water Quality Classifications, based on the adopted Water Quality Standards, establish designated uses for surface and ground waters and identify the criteria necessary to support those uses. This edition of the Surface Water Quality Classifications is based on the Water Quality Standards adopted on February 25, 2011. Surface Water means the waters of Long Island Sound, its harbors, embayments, tidal wetlands and creeks; rivers and streams, brooks, waterways, lakes, ponds, marshes, swamps, bogs, federal jurisdictional wetlands, and other natural or artificial, public or private, vernal or intermittent bodies of water, excluding groundwater. The surface waters includes the coastal waters as defined by Section 22a-93 of the Connecticut General Statutes and means those waters of Long Island Sound and its harbors, embayments, tidal rivers, streams and creeks, which contain a salinity concentration of at least five hundred parts per million under the low flow stream conditions as established by the Commissioner of the Department of Environmental Protection. The Surface Water Quality Classes are AA, A, B, SA and SB. All surface waters not otherwise classified are considered as Class A if they are in Class GA Ground Water Quality Classifications areas. Class AA designated uses are: existing or proposed drinking water, fish and wildlife habitat, recreational use (maybe restricted), agricultural and industrial supply. Class A designated uses are: potential drinking water, fish and wildlife habitat, recreational use, agricultural and industrial supply. Class B designated uses are: fish and wildlife habitat, recreational use, agricultural and industrial supply and other legitimate uses including navigation. Class B* surface water is a subset of Class B waters and is identical in all ways to the designated uses, criteria and standards for Class B waters except for the restriction on direct discharges. Coastal water and marine classifications are SA and SB. Class SA designated uses are: marine fish, shellfish and wildlife habitat, shellfish harvesting for direct human consumption, recreation and other legitimate uses including navigation. Class SB designated uses are: marine fish, shellfish and wildlife habitat, shellfish harvesting for transfer to approved areas for purification prior to human consumption, recreation and other legitimate uses including navigation. There are three elements that make up the Water Quality Standards which is an important element in Connecticut's clean water program. The first of these is the Standards themselves. The Standards set an overall policy for management of water quality in accordance with the directive of Section 22a-426 of the Connecticut General Statutes. The policies can be simply summarized by saying that the Department of Environmental Protection shall: Protect surface and ground waters from degradation, Segregate waters used for drinking from those that play a role in waste assimilation, Restore surface waters that have been used for waste assimilation to conditions suitable for fishing and swimming, Restore degraded ground water to protect existing and designated uses, Provide a framework for establishing priorities for pollution abatement and State funding for clean up, Adopt standards that promote the State's economy in harmony with the environment. The second element is the Criteria, the descriptive and numerical standards th

Atlantic Coast Title 50 Lease Exclusion Areas - Title 50:1-23 “Shellfish” describes areas in which no additional lands may be leased at the Parker Beds in Parker Cove, Forked River Beds, Cedar Creek Beds and Sloop Creek Beds in Barnegat Bay (No leases currently exist in these defined areas). Additionally, no lands under the tidal waters of the Navesink River and Shrewsbury River shall be leased for the planting and cultivating of shellfish. a line that delineates lands in tidal waters of the Mullica River in which no additional leases will be granted. The Navesink and Shrewsbury Rivers were created based upon the existing NJDEP 2015 Waterbody GIS data layer. Parker Cove was digitized based upon provided coordinates. Cedar Creek, Forked River, and Sloop Creek were digitized based upon georeferenced photographs of historic charts delineating those areas - as such, the boundaries are approximate only.Great Egg Harbor River Lease Exclusion Area - Title 50:1-23 “Shellfish” states that no additional lands shall be leased at the mouth of the Tuckahoe River and the Great Egg Harbor River. This line also defines the boundary of the area described under NJAC 7:25-19, Atlantic Coast Harvest, in which the harvest clams and oysters in the Great Egg Harbor River, Tuckahoe River and Middle River can only be established by the Division, with the advice of the Atlantic Coast Section of the NJ Shellfisheries Council by hand tongs only. Harvest shall not be permitted between June 30 to September 1 of any year. This data shows the delineation of areas above the line established on the “official chart” in which no new leases may be granted and clam and oyster harvest is restricted to hand tongs only during a harvest season.Mullica River Title 50 Lease Exclusion Area - Title 50:1-23 “Shellfish” describes a line that delineates lands in tidal waters of the Mullica River in which no additional leases will be granted. No new leases shall be granted under the waters of the Mullica River above a line extending in a westerly direction from the south end of Deep Point. Existing leases may be granted “heretofore” in this area of the Mullica. In summary, leases that were previously granted and were subsequently vacated, could be granted again.Cape Horn Lease Exclusion Area - Cape Horn (Great Bay) Lease Exclusion Area defined by the Leasing of Atlantic Coast Bottom for Aquaculture regulations is an area where no new lease applications will be accepted as it was classified as productive and new leases discouraged as per (NJAC 7:25-24.6(d)1i. The line defining the area was drawn on a NOAA Nautical Chart 12316 (23rd Ed. November 15, 1986). The chart was defined as the “Official Chart” and kept with the leasing charts at the NJ Division of Fish and Wildlife Nacote Creek Shellfish Office. The citation as adopted September 18, 1989. There are numerous current shellfish leases that were established prior to the adoption of this rule. If one of these Cape Horn leases become vacated, the vacated parcel may not be re-leased. The area was digitzied within GIS using landmarks and navigation aids depicted on the “Official Chart”. The 1986 version of the chart used for the “Official Chart” has since been updated.Goosebar Lease Exclusion Area - Regulatory area pertaining to shellfish leases: no leases allowed in area defined as the Goosebar in Little Egg Harbor Bay.Lakes Bay Lease Exclusion Area - Lakes Bay is an area defined by the Leasing of Atlantic Coast Bottom for Aquaculture regulations as an area classified as productive in which leasing is discouraged (NJAC 7:25-24.6(d)1iii. The line defining the area was drawn on a NOAA Nautical Chart 12316 (23rd Ed. November 15, 1986). The chart was defined as the “Official Chart” and kept with the leasing charts at the NJ Bureau of Shellfisheries Nacote Creek Shellfish Office.The citation as adopted September 18, 1989.Sunflower Island Lease Exclusion Area - Sunflower Island, Brigantine is an area defined by the Leasing of Atlantic Coast Bottom for Aquaculture regulations as an area classified as productive in which leasing is discouraged (NJAC 7:25-24.6(d)1iv. The line defining the area was drawn on a NOAA Nautical Chart 12316 (23rd Ed. November 15, 1986). The chart was defined as the “Official Chart” and kept with the leasing charts at the Nacote Creek Shellfish Office. The citation as adopted September 18, 1989. There are a few current shellfish leases that were established prior to the adoption of this rule.Great Sound Lease Exclusion Area- Policy area pertaining to shellfish leases: expansion of the Great Sound lease block is limited to the area between the eastern boundary line of the existing lease area to the western boundary of the existing lease area.Brigantine and Absecon Lease Restriction Area - The waters between the City of Brigantine and City of Absecon have a history of productive hard clam harvest and other commercial fisheries such as crab potting. The Shellfish Council had made several policy decisions in regard to leasing limiting additional new leases, but maintaining existing leases or eliminating certain leases that may go vacant that were established prior to the Council’s policies. These policy decisions can be found on the “Leasing Policy of the Atlantic Coast Section of the New Jersey Shellfisheries Council.” In addition, waters classified as productive hard clam habitat are discouraged from leasing as per the Leasing of Atlantic Coast Bottom for Aquaculture regulations at NJAC 7:25-24. The area was digitized in GIS based upon the NJDEP's 2015 Landuse/Landcover dataset and using geographic landmarks to delineate waterbodies defined by Council policy and areas considered productive for hard clams.Graveling Beds - Regulatory area pertaining to NJ Atlantic coast shellfish leases: no leases allowed in mapped area.The Graveling Beds are an area defined under Title 50 and the Atlantic Coast Harvest Season regulations NJAC 7:25-19. No leases are allowed in the Graveling beds. There are five main oyster reef lumps in this region known as the Graveling Beds which consist of Fitney Bit, Reef Bed, Oyster Bed Point Bed, Turtle Island Beds and an unnamed lump near Goose Cove. These beds are located within a boundary known as the Graveling Beds. Harvest in the Graveling Beds can only be established by the Division, with the advice of the Atlantic Coast Section of the NJ Shellfisheries Council by hand tongs only. Harvest shall not be permitted between June 30 to September 1 of any year.Kings Grant (Little Egg Harbor Bay) – Area of the Riparian Grant in Little Egg Harbor Bay which is known as the “Kings Grant.” This area is unleasable for shellfish as the grant is exclusive to the grant holder. This data delineates riparian grant issued in 1896. It’s called a Kings Grant, but we believe that is mistaken. The grant gives exclusive rights to the grant holders to the bottom.

The North Carolina (NC) Department of Environmental Quality(DEQ) Division of Marine Fisheries (DMF) - Shellfish Sanitation and Recreational Water Quality Section (SSRWQ) identifies Designated Shellfish Growing Areas (SGA) covering the entire NC coast. The SSRWQ performs water sampling at designated stations throughout the year to determine the extent of contamination of waters in each SGA. Based on these results, shoreline survey information, and hydrographic factors, the DMF disseminates proclamations to create closed harvesting areas with specified closure boundaries, in which the harvest of shellfish is prohibited. Waters within each SGA may be permanently closed (prohibited), restricted, open (approved), or subject to being opened or closed (conditionally approved open or conditionally approved closed) based on an existing management plan for the area.

The U.S. Food and Drug Administration (FDA) require shellfish producing states to comply with the guidelines and regulations set by the National Shellfish Sanitation Program (NSSP), Guide for the Control of Molluscan Shellfish. The guidelines consist of a Model Ordinance, summarizing the minimum requirements necessary for States to regulate the interstate commerce of molluscan shellfish (oyster, clams, mussels, and scallops) and establish programs to protect the public health by assuring the sale or distribution of shellfish from a safe source and assuring shellfish have not been contaminated during cultivating, harvesting, processing, shipping, or handling. The New Jersey Shellfish Sanitation Program addresses the classification of shellfish growing waters that are described in the Model Ordinance, requiring the State to annually appraise shellfish water to determine where shellfish (molluscan bivalves) can and cannot be safely harvested for human consumption and classify shellfish waters according to current bacteriological water quality conditions.

The Department of Marine Resources (DMR) Bureau of Public Health collects surface water grab samples at approximately 1,400 water quality stations along the Maine coast year-round. For each station, after at least 30 samples have been collected under systematic random sampling and analyzed for fecal coliforms, DMR scientists calculate final scores which, along with sanitary surveys of the area, help determine whether the water quality is acceptable for harvesting shellfish. Fecal coliform results are reported as the number of colony forming units (individual bacterium capable of forming colonies) per 100mL of water. Most sample sites show a range of scores, and some sites may have high as well as low scores.The DMR Shellfish Growing Area Classification Program classifies shellfish areas as Approved, Conditionally Approved, Restricted, Conditionally Restricted or Prohibited using standards set by the National Shellfish Sanitation Program (NSSP), a federal/state cooperative program that sets the requirements for all states involved in interstate shellfish harvest and sale. For more information about the classification of shellfish flats, visit https://www.maine.gov/dmr/shellfish-sanitation-management/programs/growingareas/index.html.All classifications are based on two factors: the results of a shoreline survey which looks for the presence of pollution sources and fecal coliform test results. Two statistical values are calculated from the most recent 30 fecal scores: the geometric mean (geomean) and the 90th percentile (P90). The standards for Approved classification are 14 CFU or less (geomean) and 31 CFU or less (P90). The standards for Restricted are 88 CFU or less (geomean) and 163 CFU or less (P90). The standards for Prohibited are greater than 88 CFU (geomean) and greater than 163 CFU (P90).End of year 2021 P90 data for all Maine active water quality stations based on the most recent 30 samples. Conditional Area stations are based on last 30 samples in the open status. Data projection is NAD 1983 UTM Zone 19N.

The Inventory of New Jersey’s Estuarine Shellfish Resources is conducted on a rotating basis throughout the major Atlantic coastal estuaries of New Jersey. The primary purpose of the work is to estimate the standing stock of hard clams (Mercenaria mercenaria) and describe their relative distribution. Additionally, the survey describes the relative distribution of other commercially important bivalve species. Hard Clam: The substrate is sampled with a hydraulic hard clam dredge designed to retain clams sized 30mm and larger. All live clams collected are counted and measured to the nearest millimeter. The density of clams at each station is reported in clams per square foot. The resulting geospatial data represents the relative distribution of hard clams at either “none” (no clams collected), “low” (0.01 to 0.20 - 0.50 clams/ft2) densities. Where no category designation is given, the area is considered a “no data” area relative to this survey. This means that the survey did not sample within this area for reasons including shallow water, obstructions, or the presence of shellfish aquaculture leases. The area may or may not be marked formally as such. However, a “no data” area may contain shellfish resources unknown to the Marine Resources Administration (MRA) or the MRA may have data for the area from other investigations. It does not automatically mean that the area is devoid of shellfish resources. This data represents a one point in time documentation of relative abundance of hard clams, and hard clams may be found presently in areas not previously sampled or at stations where they were not historically collected. Complete reports for each surveyed estuary provide methodology, analysis, charts, and additional pertinent information, and can be found at on the NJ Fish and Wildlife’s website. The NJ Coastal Zone Management rules at N.J.A.C. 7:7 define shellfish densities of 0.2 clams per square foot or greater as productive shellfish habitat. The Leasing of Atlantic Coast Bottom for Aquaculture regulations discourages establishing leases in productive shellfish habitat (NJAC 7:25-24.6(d)). Note that this layer does not include delineation of shellfish leases or aquaculture development zones. Those data are provided separately. Data from 1980s were digitized based primarily on the georeferenced images of the 1980s’ map series, in combination with usage of the 1986 NJDEP Landuse/Landcover geospatial dataset to more accurately depict shoreline boundaries. Digitizing was completed using freehand and/or copying/pasting/editing waterbody features from the 1986 NJDEP Landuse/Landcover geospatial dataset. Digitizing was completed at a scale between 1:4,000 to 1:12,000. This data represents a digital interpretation of the original hard copy charts. Therefore, some anomalies may exist in the line features along the present-day coastline. Users should interpret the mapping to extend to the present-day coastline. Data from 2000s to present were created based upon survey station tabular data which was then mapped as a point feature class. Several GIS tools were then used to generate polygon features surrounding the stations to represent hard clam distribution (see Process Steps for more detail). Associated Species: When other commercially or recreationally important bivalve species are retained in the sample, they are documented, along with common invertebrate species. Data from the 1980s documents the presence of all other commercially and recreationally important bivalve species that are regulated by the State of New Jersey as well as common (but not all) shellfish predators that were retrained in the dredge while targeting hard clams. Presence indicates the area is productive for the species. The regulated bivalve species are soft clams (Mya arenaria), bay scallops (Argopecten irradians), surf clam (Spisula solidissima), Eastern oyster (Crassostrea virginica), and blue mussel (Mytilus edulis). This data is aone point in time observation of production areas and regulated bivalve species may be found presently in areas not previously sampled or at stations where they were not historically collected. This data represents a digital interpretation of the original hard copy charts. Therefore, some anomalies may exist in the line features along the present-day coastline. Users should interpret the mapping to extend to the present-day coastline. It is important to note that this data is not a comprehensive evaluation of Eastern oyster populations in the Mullica River, Great Egg Harbor River, or Delaware Bay, which are surveyed separately and specifically for that species. Similarly, although surf clams are occasionally found in estuarine environments, the species primarily dwells in the Atlantic Ocean and separate comprehensive population surveys of state and federal waters are available. For additional species collected (for example sponges, non-commercial shellfish, etc.) please contact the Bureau of Shellfisheries. Historical reports for each surveyed estuary provide methodology, analysis, charts, and additional pertinent information, and can be requested by contacting the Marine Resources Administration.

Data has been sourced from the ESTAR database. Under the Bivalve Molluscan Shellfish Regulated Control Scheme, every classified growing area must undertake regular shellfish and water monitoring for toxigenic phytoplankton and marine biotoxins. This map shows the referenced location of these sample sites. Note that historically the location of these sample sites was not very accurate. The number of routine sample sites has been reduced dramatically over the years as more knowledge has been gained and also due to budget constraints. Some of the sites on this layer include the regular monitoring sites for the non-commercial marine biotoxin monitoring programme.This data set is the non-editable version of Marine biotoxin sample site locations.A memo for the release of this data is available to MPI staff here.
