| | | 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 | GIS and remote sensing supported aquaculture potential assessment for the lower stretch of the SÃO JOÃO River - RJ, Brazil | | Author | Claudio Michael Völcker and Philip Conrad Scott | | Date | 12 December 2008 | | Content Language(s) | English | | Abstract / Description | This study was carried out in order to identify the potential and suitable areas for land-based aquaculture development along the lower stretch of the São João river, RJ – Southeast Brazil. A Geographical Information System was using several image sources. Two models were developed integrating important environmental criteria for euryhaline species already cultured in the study area which include – Litopenaeus vannamei, Macrobrachium rosenbergii, and Oreochromis niloticus. The choice of suitable areas was based on processing several images integrated in a multicriteria evaluation (MCE), with the use IDRISI®, a raster based GIS software. Areas with development restrictions were identified and excluded. Analytical Hierarchy Process (AHP) was used to establish weights for the MCE generating suitable areas for each species. The total suitable area found was 55.79 km2. In total, 667ha were found suitable aquaculture, of which 4,697ha for Litopenaeus vannamei culture, 4,905ha for Macrobrachium rosenbergii and/or Oreochromis. niloticus. It is expected that this information will be found useful for regional planners, managers and potential investors. Abstract presented at the Fourth International Symposium on GIS/Spatial Analysis in Fishery and Aquatic Sciences in Rio de Janeiro, Brazil, from 25–29 August 2008. | | Publisher | Fishery-Aquatic GIS Research Group | | Publication Location | Japan | | Download | | | Keywords |  GIS | |
