Tests Reveal Mislabeling of Fish

New DNA sequencing techniques used by biologists and advocates for sustainable fisheries has revealed that 20-25% of all commercial fish are mislabeled to the public. And so, though you paid for Mahi Mahi you might be getting Yellowtail or Mako Shark instead of Swordfish. Tilapia is also frequently mislabeled as other species as it is cheap to farm and very profitable for the unscrupulous to sell. The FDA has been behind the curb on this issue and a great deal of over-fishing combined with such tactics threatens to destroy a naturally occurring and sustainable resource, fish in the ocean. For those interested in this critical issue I recommend the excellent documentary "The End of the Line," available for streaming or DVD delivery on Netflix.
