| | | Review of the literature is an essential starting point for any endeavour in GIS, remote sensing, or mapping. Yet, reviews are often incomplete for lack of access to the material, and consequently projects experience durations that are longer and costs that are higher than need be because the accumulated knowledge has not been tapped and taken advantage of. This page sets out to mitigate that problem. It is a gateway to the literature that represents much of the accumulated global experience on using GIS, remote sensing and mapping to solve problems and issues in aquaculture and inland fisheries. Spatial issues addressed most frequently for aquaculture and inland fisheries are listed in two tables in issues section along with the number of literature records currently contained in GISFish databases. Four recent studies available for download in issues section provide background information on GISFish databases. | | | |

| | | Title | SHELLFISH AQUACULTURE VULNERABILITY MODEL | | Author | CENTER FOR COASTAL RESOURCES MANAGEMENT, VIRGINIA INSTITUTE OF MARINE SCIENCE | | Date | November 2007 | | Content Language(s) | English | | Abstract / Description | Aquaculture is a multi-million dollar industry in Virginia. Presently, Virginia leads the nation in the production of clams grown in cultured environments and distributed in the seafood market. Most aquaculture in Virginia is located on the Eastern Shore; however, commercial operations are expanding on the western shore as well.
Aquaculture is an environmentally sensitive industry which requires good water quality for successful growth as well as distribution for human consumption. The later is regulated through the State’s Division of Shellfish Sanitation within the Virginia Department of Health. Threats to water quality are caused largely by land use practices, failing septic and animal waste. Currently development and agricultural practices present the greatest threats. In the future, the potential conversion of land uses through regulated zoning at the local level poses a significant risk to the future of aquaculture in Virginia.
Natural resource agencies in Virginia are aware and concerned about the future of aquaculture in the commonwealth. The largest shellfish growing operations exist in relatively rural communities, and the pressure for development has already elevated the water quality issue. Among the list of impacts that large scale housing developments pose include: point source discharge from sewage treatment facilities, non-point source discharge from surface runoff due to impervious surfaces, and the overall reduction in nutrient uptake due to clear cutting of riparian forest buffers.
While predicting future water quality conditions in the Chesapeake Bay and seaside of the eastern shore is extremely difficult, we can attempt to model where the risk of water quality degradation due to land use practices might occur based on existing and proposed land use. These data are available through a variety of federal, state, and local government data sources. This approach was the focus of the project objective and was applied in three localities: Gloucester, Accomack, and Northampton Counties. | | Publisher | CENTER FOR COASTAL RESOURCES MANAGEMENT, VIRGINIA INSTITUTE OF MARINE SCIENCE | | Publication Location | COLLEGE OF WILLIAM AND MARY, GLOUCESTER POINT, VIRGINIA 23062 | | Download | | | Keywords |  AQUACULTURE | |
