Use of geographic information system technology (GIS) and relational database technology could provide significant benefits to fishery scientists, resource managers, and the fishing industry.  Large, well-established fisheries databases can be linked and accessed using a user-friendly interface on personal computers and workstations making fisheries and other data more accessible to a variety of users. This project began with a conceptual model which later led to a working computer prototype.  The utility of the proposed system, using actual fisheries data, was demonstrated by applying the fisheries information management system to six management scenarios.
