| | | 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 | The use of the SIG in the aquaculture mapping and research of the Cocanha Island, São Paulo State, Brazil | | Author | Fausto SILVESTR, Thiago Cabral VILAR, Fabrício de Sá OLIVEIRA and Alexander TURRA | | Date | 12 December 2008 | | Content Language(s) | English | | Abstract / Description | The use of a geographic information system (GIS) directed to the aquaculture is supposed to aims the sustainability of the activity and to order aquaculture areas. Its specific objectives are focused in registering and controlling projects, thus geographically referencing strips or areas of preference to create and to keep a database on the concessions of use. In this context, the present work establishes a specific case study on how a SIG can favor the monitoring of the mussel culture. Aiming to spacially represent the area of culture of mussels (Perna perna) off Cocanha beach, northern part of Caraguatatuba City, State of São Paulo, Brazil, the free software SPRING 4.3.3, developed by Instituto Nacional de Pesquisas Espaciais (INPE), was used. First an air photograph of the region was imported from an INPE database, in the resolution of 0,98m. After that, this photograph was georeferenced using points registered in field using a portable GPS (Garmin Etrex Legend). The next step was to delimit the total area of culture and to determine to the position of each long-line in this area using known geographic coordinates. From this information it was possible to build a geographic database with their respective categories and plans of information. In parallel, inquiries in situ were carried to generate data on the production of long-lines (total amount of ropes and developmental stage) and the percentage of epibiont organisms in the mussel ropes. Nine analyzed points had indicated the situation of epibiosis in long-lines (Map 1), allowing estimates of the average percentage of epibiosis on mussels. This geographically referenced information allowed the localization of each analysis and their respective evaluations, providing an alternative of managing and offering support for the taking of decisions. The union between biological information with the geographical interface may thus favor the interpretation and management of the mussel farms in relation to the environmental dynamics. This method of work constitutes an efficient tool for the integrated coastal management of the mussel cultures, being able to be used to managers, researchers and producers.
