Recaptured GPS Tags!!
In May 2004 the Marine Research Institute in Iceland was the first institute in the world to take into use the pioneering DST GPS fish positioning system made be Star-Oddi and Simrad. For the last few months some of the tagged cods have been recaptured and three of them had recorded GPS code sent from a research vessel carrying a Simrad sonar. The cods that carried the three tags provide invaluable information about the fish migration pattern and the fish behavior, information that is not possible to obtain by other means for reasonable cost. The DST GPS tags store information about the fish GPS position that is sent from a vessel in parallel with temperature and depth.
The picture below shows the recaptured GPS tags that had a received a GPS code sent from a research vessel that transmitted the code with a Simrad sonar. The three tags are displayed with different color, and with date.
