| | | 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 | Integrated coastal zone management: use of Geographical Information Systems as a tool for characterization of sea shrimp farm areas in southern Brazil | | Author | Rodrigo Randow de FREITAS, Carlos HARTMANN, Luís Henrique da Silva POERSCH and Paulo Roberto Armanini TAGLIANI | | Date | 12 December 2008 | | Content Language(s) | English | | Abstract / Description | In the Rio Grande do Sul state, sea shrimp farming activity is in expansion ever since the exotic shrimp Litopenaeus vannamei was introduced. Today, four farms are productive in the state, and are installed in the municipal districts of São José do Norte and Rio Grande; another four farms already possess previous license for work. Along with the activity’s potential productive growth comes an increase of environmental and socioeconomic impact risks, which can directly affect sustainability of the activity. Several examples confirm such statement, with similar problems reported for countries that saw the exponential growth of their activity, but with consequent productive, legal and environmental problems. Therefore, a manner of providing long-lasting development of the activity is through planning and decision management of enterprise development at coastal areas, by employing Geographical Information Systems (SIG). The present study proposed the identification and characterization of areas destined to sea shrimp farming in RS, supported by orbital (ETM+/Landsat, Google Earth), airborne (35 mm/ADAR 1000 system), terrestrial (RICOH 500SE) and field expedition remote sensing techniques and methods, integrating data in a Geographical Information System (in IDRISI Andes Edition – ver. 15.01). The study area included the municipal districts of Rio Grande and São José do Norte, located in the Southern portion of the Patos Lagoon estuary (31º00'N and 51º16'W) and comprising an area of approximately 10144 km². Results indicated that enterprises were built on coastal fields or in areas of obliterated dunes, which are favorable for farming. The proximity of possible consuming markets and local labor, relatively good access roads, available electric network and local technical support (FURG-EMA) are also favorable to the projects. However, there is concern as to changes in the original projects, causing environmental impacts and noncompliance of environmental norms. An example is the occupation of salt marsh areas. Based on the obtained information, instruments can be created for aiding the inherent legal decisions of administration of the activity for future enterprises.
