Fi.S.A.R.: A Data-managing and Processing Software for Automated Telemetry Systems
Abstract:Ultrasonic telemetry systems are increasingly used in studies on the behavioral ecology of marine and freshwater animals. Systems based on automated omnidirectional receivers in particular offer a powerful and relatively cheap tool to provide presence/absence data of tagged animals, but they do not provide the geographic position of the transmitters. In this paper a new software called FiSAR (Fish-finder Software for Automated Receivers), developed for application with Vemco VR1/VR2 receivers, is presented (available at www.marecofree.org/download.asp). FiSAR is able to manage large datasets as well as to calculate the activity center of each transmitter from simple presence/absence data. This is achieved through (1) the collation of the data collected by each receiver in a unique MS Access cross-table, and (2) the use of the Simpfendorfer et al. (2002) algorithm. The resulting cross-table can be easily exported to most statistical packages for further analysis.
