Conteúdo: | Geographic Information Systems have been used as tools for data analysis and information generation for aquaculture for more than two decades. The Food and Agriculture Organization (FAO) provides, through GisFish1, a collection of documents about them, including scientific articles, technical reports, tutorials and practical experiences. The main topics are: ?site assessment?, which concerns the characteristics of a place (bay, lagoon, dam, etc.) through descriptors; ?potential assessment?, which analyzes, by factors, the spatial variability of potential levels in a local; and ?site selection?, delimiting specific sites for aquaculture based on the description, potential and constraints. Therefore, the main objectives of applied studies have been: "to assess a local", "to evaluate the potential? and "to select sites for aquaculture". Despite the knowledge generated by these experiments, the use of GIS in the implementation of aquaculture public policies is not so expressive. The hypothesis is that it is associated with methodological and conceptual issues. Through the survey and classification of 73 publications available on GisFish between 1985 and 2009, I analyzed the subject matter covered, objectives of GIS applications, terms used in the results, aquaculture type, implementation, data model, analysis technique, decision making, and decision under uncertainty. The results show that 92% of the articles are technical or research papers and only 8% are practical applications or public policies. The main goals are treated as synonyms and, regardless of the subject the terms used in the presentation of the results are mixed, without a conceptual standard. In some articles about potential assessment, for example, it is common to find as the main goal "to select sites", which involves different aspects in a management process. The decision making process in potential assessment and site selection publications are not clear. Just 21% described the process, of which 63% did so in a participatory manner and the other 37% were based on references. Reverting these research experiences into practical applications requires a review of conceptual and methodological problems. So, a proposal is presented in which the aims of ?site assessment?, ?potential assessment? and ?site selection? are structured as phases of a management participation process with the use of GIS (PPGIS) and the terms used in the presentation of the results of each are suitable for the objectives.
