A major conservation survey assessed 64 species of open ocean sharks and rays and found that one third of them face extinction, including the great white shark. The study by the International Union for Conservation of Nature (IUCN) reported that species hunted on the high seas are particularly at great risk, with over half in danger of extinction. The IUNC named tuna and swordfish fisheries as the main culprits for their accidental "by-catch" of sharks. Sharks are also being increasingly...

In the famed Sharktooth Hill Bone Bed near Bakersfield, Calif., shark teeth as big as a hand and weighing a pound each, intermixed with copious bones from extinct seals and whales, seem to tell of a 15-million-year-old killing ground.Yet, new research by a team of paleontologists from the University of California, Berkeley, the University of British Columbia in Vancouver, Canada, and the University of Utah paints a less catastrophic picture. Instead of a sudden die-off, the researchers say...

Census of Marine Life historians meeting in Vancouver, Canada, say they have reconstructed images of past sea life that boggle the imagination. The researchers said they used such sources as old ship logs, literary texts and tax records to reconstruct what life in the ocean was like prior to the early 1800s. Before oil hunters harpooned whales by the hundreds, the ocean around New Zealand teemed with about 27,000 southern right whales - roughly 30 times as many as today, the scientists said....

With shark populations tumbling around the world, Chinese cooks are turning to manta and devil rays to fill their shark fin soup pots. Until recently, the rays were targeted only by subsistence fishermen, The Times of London reported Friday. Now, about 1,500 big manta rays are taken every year in the Indonesian fishing port of Lamakera. Tim Clark of the University of Hawaii said the rays could be overfished quickly. They have a long lifespan -- possibly more than 50 years -- and do not begin...

KEY WEST, Fla., May 13 /PRNewswire/ -- SharkDefense Technologies and HEFA Rare Earth Canada, Co. Ltd. announced today that shark-repellent metal alloys are available for sale. The metal alloys are proven to reduce the accidental capture of sharks and are anticipated to benefit many commercial fishing operations. The shark-repellent metal alloys work by generating a small voltage in seawater, which affects a shark's electric sense. Bony fish, such as tuna, do not have the organ responsible...
