Cultivation of cobia (Rachycentron canadum) in Cananeia, SP, Brazil. Feasibility assessment using GIS The Food and Agriculture Organization of the United Nations (FAO) frequently publishes reports about world fisheries production. These reports state wild fish stocks increasingly depleted and mariculture production growth in the past decade. The mariculture emerged then as an alternative to food production and generating income. Cobia, Rachycentron canadum, has been highlighted in recent years and is being studied in different aspects aiming its commercial production in Brazil. As mariculture has expanded, the development of management instruments for coastal zone is shown increasingly necessary. As establishing a sustainable basis to select the proper location to install fish farming it is possible to maximize the efficiency mariculture, producing raising the maximum number of organisms with minimal costs. This viability occurred through the understanding of the relationship between the physiological requirement of the aquatic organism selected and the environmental conditions. Data were obtained through literature searches, documents from government agencies, restitution of satellite images and field sampling organized in a manager geodatabase and analyzed using geostatistical interpolation, distance and density analysis to define ideal areas of Cananéia´s estuary and coastal zone to cultivate Cobia. The current work indicates areas suitable for growing Cobia in the studied region considering environmental, socioeconomics and logistics variables. The Geographic Information System (GIS) has shown itself capable of contributing effectively, facilitating potential shell fishermen and manager decision making.
