How False killer whale’s remove bait from longline fishing gear captured on video for first time

How Hawaiian false killer whales remove fish from longline fishing gear has for the first time been observed by a team of researchers and fishermen. The team, coordinated by Scripps Institution of Oceanography at the University of California San Diego scientist Aaron Thode, used video and audio recordings to observe false killer whales removing fish from a longline fishing hook, a behavior known as depredation. They gained new insight into a behavior that has caused false killer whales to entangle with fishing gear at rates deemed unsustainable by the U.S. National Marine Fisheries Service. To observe false killer whales removing fish from hooks, the Alaskan and Hawaiian research team deployed an underwater camera, sound recorder, and vibration detector on long-line fishing gear deployed by fishing vessels off Hawaii. Read the article here 16:40

A Tale of Two Whales: Seven-Year Study Indicates Steady and Upward Trends for Blue and Fin Whales in Southern California

A new study led by researchers at Scripps Institution of Oceanography at UC San Diego indicates a steady population trend for blue whales and an upward population trend for fin whales in Southern California.Blue and fin whales are common inhabitants of the Southern California Bight, the curved region of California coastline with offshore waters extending from San Diego to Point Conception (near Santa Barbara, Calif.), but little is known about their use of the area.

Exposed; “The Devolution of the Seas,”, Alan Sielen opts for outdated and refuted information on tuna stocks

logoWASHINGTON (Saving Seafood)February 24, 2014 — Writing in an essay originally published in Foreign Affairs, (“The Devolution of the Seas,” November/December 2013) Alan Sielen, a Senior Fellow for International Environmental Policy at the Scripps Institution of Oceanography, paints a dire picture of the state of the world’s oceans, claiming that “humanity has come perilously close to reversing the almost miraculous biological abundance of the deep.”  But in his highly selective and misleading portrayal of the current state of fisheries management, Mr. Sielen gets several key facts wrong, and recirculates ideas that are either highly disputed or have been thoroughly refuted by the marine science community.
