"Fishazam" app could end fish fraud by identifying fillets

With fishmongers and wholesalers passing off one third of catches as more expensive species, rampant fish fraud is preventing governments from accurately monitoring fish populations. Fishazam, an app born out of a US State Department hackathon, makes it easy for shoppers and restauranteurs to identify the species and source of a fillet. Fishazam uses a version of the song-identifying app Shazam's alogorithm to recognise molecular patterns.
