Hidden Cost Of Shark Fin Soup

Shark finning articles are becoming more mainstream. The NY Times has an article about shark fishing in Manta, Ecuador, a location I have been to and documented as well. It's a well-written article, but I find it strange that it focuses on a place where the entire shark is actually used. In a large market area on the beach itself, virtually every piece of the sharks pulled up are sold to locals as inexpensive meat. Where are the mainstream articles that document shark-finning proper, where the live carcasses are discarded?
