Abstract:
The Designated Shellfish Growing Area (DSGA) datalayer was compiled by the Department of Fisheries, Wildlife and Environmental Law Enforcement's (DFWELE) Division of Marine Fisheries (DMF). Three hundred and three growing areas in Massachusetts have been designated by DMF's Shellfish Project.

A designated shellfish growing area is an area of potential shellfish habitat, and all three hundred and three DSGA's make up the territorial waters (tidal zone out to the territorial line) of the Commonwealth. Growing areas are managed with respect to shellfish harvest for direct human consumption, and comprise at least one or more classification areas. The classification areas are the management units, and range from being approved to prohibited (six different classification types in all) with respect to shellfish harvest. For example, one growing area may be composed of four classification areas, all of which are managed separately (have a classification type the same or different from the rest in the growing area). This layer reflects classification areas as of July 1, 2000.

A single polygon coverage named DSGA is stored in the NE library. In ArcSDE the DSGA data are stored in two feature classes - DSGA_POLY and DSGA_ARC.

The Division of Marine Fisheries and MassGIS are maintaining this datalayer. Also see Shellfish Suitability Areas datalayer description.

Data_Quality_Information:
Lineage:
Process_Step:
Process_Description:
The growing areas and their classification areas were defined by DMF shellfish project biologists. Compilation base maps covering the entire coast and islands were plotted at 1:12,000 using hydrography from 1:24,000 USGS DLG; 1:100,000 USGS DLG; and 1:25,000 USGS Topographic maps, all modified and enhanced by MassGIS.  In addition, town boundaries, the territorial waters line and roads were plotted on these base maps. Shellfish project biologists compiled area boundaries onto the base maps, and these boundaries were then digitized or constructed using existing hydrography, town or territorial sea lines by DMF GIS personnel.  Check plots were created and boundaries QA/QC'd by the biologists.

Separate 11 x 17 color plots are produced for each growing area based on the mapextent of the area and its sampling stations. Classification area lines which need to be added, moved or deleted are compiled on these plots and automated by DMF GIS staff. A new 11 x 17 is produced and kept on file until another area change occurs.

Overview_Description:
Entity_and_Attribute_Overview:
The two ID's (GRW_AREAID and CL_DESC_ID) link to ID's in several different tables in an Oracle relational database.  Information in the database is extensive and covers the area names and classification types, legal boundary descriptions, date of classification, rainfall data and acreage figures.  Historical information about each area is maintained, beginning January 1, 1995. In addition, area information is also associated with water quality and marine biotoxin sampling data collected by shellfish project biologists, used to manage the areas.  A separate GIS datalayer called SHLFSHST has been created to maintain the sampling points; see the Shellfish Sampling Station Datalayer description for details.
