Shark fin DNA test "conservation breakthrough"
Now regulatory bodies can tell if endangered sharks are on the menu. Dried shark fins look puzzlingly similar, and even experts can't always tell if one has come from a protected species. Now the Wildlife Conservation Society and Nova Southeastern University
have developed a special test to identify 10 threated types of sharks by the DNA left in the fin. Cursory tests in a Hong Kong fish market showed a fifth of the fins tested were mislabled. This will ultimatly make it simpler to prove the impact of fisheries on endagered species.
