Dr. Cazelles, recent post-doctoral researcher with BiRN, talks here on the BiRN podcast about his work using biological tracers as a spatial fingerprint to monitor the movement of seafood on the globe. This bioinformatic work uses multiple levels of geographical data to determine the source of any seafood found in a market. A complimentary tool to the work of BiRN researchers using DNA to determine species, taken together they promise to significantly aid the development of a sustainable sea food future.
