Description: These datasets exist in raster and vector formats. The vector format was created from the SHA Shoreline file and graphic representations in the Lippson book (See bibliography below). These areas were then overlane with a point file created from lat/long collected during the surveys conducted by O'dell, Mowrer, and Uphoff of MD DNR Fisheries Service. This was done to verify that the graphic representations were accurate. These data sets were then converted to raster format and reclassified with a rank determined by DNR biologists. This rank determines level of habitat importance with spawning areas ranking highest and adult areas of bay depth below 3 feet ranking the lowest. These ranked rasters were then stacked and an output raster was created showing areas of high habitat diversity. These rasters were then clipped by county.

Description: The Sensitive Areas Striped Bass dataset shows areas within Maryland's Coastal Bays that are significant for Striped Bass populations. This dataset shows seasonal use of certain areas of the bays by Striped Bass during spawning season.

Description: These datasets exist in raster and vector formats. The vector format was created from the SHA Shoreline file and graphic representations in the Lippson book (See bibliography below). These areas were then confirmed with the White book (See bibliography below) and the "Habitat Requirements for Chesapeake Bay Living Resources". While not a fishery in Maryland, they are a prey species for larger fisheries in the Chesapeake. These data sets were then converted to raster format and reclassified with a rank determined by DNR biologists. This rank determines level of habitat importance with spawning areas ranking highest and adult areas of bay depth below 3 feet ranking the lowest. These ranked rasters were then stacked and an output raster was created showing areas of high habitat diversity. These rasters were then clipped by county.

Description: The Maryland Artificial Reef Initiative (MARI) is a state-run initiative, managed by the Maryland Department of Natural Resources, aimed at developing new fish habitats in the Chesapeake Bay by way of depositing artificial materials (such as concrete reef balls or recycled porcelain) to the bottom of designated sections of water in the Chesapeake Bay. The goal is to see an oyster population develop on the artificial materials, which can attract fish and other marine creatures to the site.

Description: Dataset shows popular recreational fishing spots in the Maryland portion of the Chesapeake Bay. Fishing areas were derived from the publication "Anglers' Guide to the United States Atlantic Coast, Fish, Fishing Grounds & Fishing Facilities"and from personal communication with Keith Lockwood, MDNR, Fisheries Service in 2000.
Description: As defined in Maryland regulation, a pound net means a fixed entrapment gear consisting of: (a) A net body or crib measuring at least 16 feet long by 16 feet wide at the surface of the water with a netting floor and open top; (b) Mesh webbing with a twine size of #12 or larger; (c) At least one heart leading into the crib; and (d) A leader or hedging. Pound net sites in the Maryland portion of the Chesapeake Bay and its tributaries must be registered with the Department of Natural Resources.
Description: The Sensitive Areas Foragers and Grazers dataset shows areas within Maryland's Coastal Bays that are significant for aquatic Forager and Grazer populations. The areas less than 3 feet deep are important to Foragers and Grazers. This dataset shows cumulative seasonal use. It does not break out the seasonality of use of certain areas of the Bays by aquatic Foragers and Grazers.
