Abstract
 Measuring Shortest Distance between Fisheries Tag-Recapture Locations within Estuaries Track: Ocean, Coastal, and Marine Resources Author(s): James Burd, Jr. In fisheries research, tag and recapture data is very common. Fisheries scientists are often interested in the measurement of shortest distance between tag and recapture locations. In open marine systems, this is easily calculated within a GIS. However, in estuarine systems where fish movement is constrained by land, the calculation of shortest distance becomes more complicated. This presentation will compare using cost distance within Spatial Analyst and distance along a network to measure shortest distance in the Indian River Lagoon estuarine environment.
