• american_oysters  American_oysters is a Polygon dataset and contains distribution information for american oysters (Crassostrea virginica) for the coast of Maine . Polygons are based on locations indicated by town officials, harvesters, Harbormasters, DMR biologists, DMR specialists or DMR scientists from February 2008 to May 2009. POLYGON codes include: Town, County, Species, NOAA_Chart, Updated, Shape, ACRES, OBJECTID, SHAPE_AREA, SHAPE_LEN, and Source. - Download this layer
  
  
• ashab3  ASHAB3 contains arcs representing important Atlantic Salmon habitat in Maine, suitable for mapping at 1:12,000 or smaller scale. This dataset was developed from field surveys conducted on the main stem and/or selected tributaries of the Aroostook, Dennys, Ducktrap, East Machias, Kennebec, Machias, Passagassawakeag, Penobscot, Pleasant, Presumpscot, Sheepscot, St. George, Tunk and Union Rivers in Maine by staff of the Maine Atlantic Salmon Commission and U.S. Fish and Wildlife Service. These surveys were conducted to identify important Atlantic salmon habitat including spawning and rearing areas. The majority of the survey data was collected using Trimble Pro, Pro-XL and GeoExplorer3 receivers and survey files were differentially corrected to provide 2-5 meter accuracy. Surveys for some reaches were collected with minimal or no GPS control points and the attributes were overlaid on a stream centerline created using either a GPS-acquired line, a line derived from MEGIS/USGS 1:24,000 hydrography data, or a line drawn as a centerline based on MEGIS 1-meter Digital Orthophotography. The dataset includes information on habitat categories and areas, and an indication of spawning and rearing potential, as well as detailed attribute information concerning stream dimensions, substrates, vegetation, and other stream characteristics. - Download this layer

Polygons are based on locations indicated by town officials, harvesters, Harbormasters, DMR biologists, DMR specialists or DMR scientists from February 2008 to May 2009. POLYGON codes include: Town, County, Species, NOAA_Chart, Updated, Shape, ACRES, OBJECTID, SHAPE_AREA, SHAPE_LEN, and Source. - Download this layer
  
  
• blue_mussels  Blue_mussels is a polygon dataset and contains distribution information for blue mussels (Mytilus edulis) for the coast of Maine . Polygons are based on locations indicated by town officials, harvesters, Harbormasters, DMR biologists, DMR specialists or DMR scientists from February 2008 to May 2009.

• class03e  CLASS03E is a REGIONS dataset and contains status of molluscan shellfish growing area classifications for the coast of Maine, as of July 2003, east of Fort Point Stockton Springs, excluding Islesboro, Vinalhaven, and North Haven, suitable for mapping at 1:24,000 scale. Area boundaries are based on descriptions contained in legal notices, which are published as changes occur. POLYGON codes include CLOSURE area number, CLASSIFICATION, and ACRES. ARC coding distinguishes the 1:24000 coastline from screen digitized classification lines. - Download this layer
