'Ten Commandments' could improve fisheries management

SAN FRANCISCO, Calif. Poorly managed marine fisheries are in trouble around the world, researchers say, while ecosystem-based management is a powerful idea that in theory could help ensure sustainable catches - but too often there's a gap in translating broad concepts into specific action in the oceans that successfully meets these larger goals.

To address that, Mark Hixon, a professor of zoology at Oregon State University, today modified a very old set of rules and issued "Ten Commandments" for ecosystem-based fisheries science, in a presentation at the annual meeting of the American Association for the Advancement of Science. Co-authors on the report include Robert Francis, a professor of fisheries at the University of Washington, and three biologists in the National Marine Fisheries Service.

The first commandment what they call the basis for all the others is to keep a perspective that is holistic, precautionary and adaptive, Hixon said.

"We must consider whole systems, we must fish with more caution, and we must learn by testing new approaches," Hixon said. "Instead of talking about ecosystem management, we refer to 'ecosystem-based' management, because it's misguided to think that we can totally understand or completely control entire marine ecosystems." However, a great deal is already known that could form the basis for broad actions which would greatly improve the effectiveness and efficiency of marine management, Hixon said, and it's not really even a question of funding many of the necessary steps could be done within the context of existing knowledge, approaches, and regulatory mechanisms.

"As much as anything, the real challenge here is changing our world view," Hixon said. "We must accept the need for change in how we approach fishery science and management. There are still many people who think we can accomplish our goals in the oceans by managing one species at a time, if we just do it right. But the weight of the e
