Bar-Coding Fish: Scientists to track world’s marine life with supermarket technology

According to Ron O'Dor, head of the Ocean Tracking Network to be set up at Dalhousie University in Canada, "we know less about our marine life -- how these animals live, where they go -- than we know about the back side of the moon." To change that, scientist want to use electronic tags to basically bar-code salmon, tuna, sharks, sturgeon, penguins, or perhaps polar bears. The animal's movements would then be read by devices similar to supermarket scanners on the floors of the oceans or via satellite. Let's hope this version of the technology works better than what's at the local market, where (canned) tuna has to pass by the scanner six times before it's counted.
