Overfishing and bycatch of Open Ocean (pelagic) Sharks and Rays is driving them to the brink of extinction. A recent study by the International Union for Conservation of Nature (IUCN) Shark Specialist Group, has set the alarm bells ringing. The study found that 32 percent of the species are threatened with extinction. They are now more threatened than birds (12percent), mammals (20 percent), and even amphibians (31 percent).

The demand for shark meat and fins are on the rise. Shark fin soup is considered a delicacy in many areas. In finning the crudely is abhorrent. The fins are sliced off the shark and the body tossed overboard.Sharks take many years to mature and have relatively few young. So the effect of overfishing is profound.

IUCN has requested all countries to strictly enforce laws and protect the species considered Critically Endangered and Endangered. 24percent of the species are Near Threatened and 25 percent Data Deficient.
