Florida scientists develop way to detect mislabeled fish
A pair of Florida scientists have developed a device they say can genetically verify whether imported fish destined for dining tables are grouper or less expensive, potentially harmful Asian catfish often passed off for the popular firm-fleshed fillets. By early summer, Tampa-based PureMolecular LLC hopes to begin selling the fist-sized machines for about $2,000 apiece, said John Paul, the company's chief executive and a marine science professor at the University of South Florida.
