The growing popularity of farm-raised salmon has plunged the commercial fishing industry in the Pacific Northwest into a state of crisis, according to a new report by Stanford University researchers.
Writing in the October issue of ENVIRONMENT magazine, the research team found that, since the late 1980s, worldwide production of farm salmon has increased fivefold, while the market share of wild-caught salmon from Alaska, British Columbia and Washington state has steadily declined.
"Farm salmon represents one of the fastest-growing and most lucrative segments of the global aquaculture industry," said Josh Eagle, director of the Stanford Fisheries Policy Project and co-author of the ENVIRONMENT report. "In 1980, commercial fisheries produced more than 99 percent of salmon consumed worldwide. Today, they catch less than 40 percent."
"Unless some actions are taken on a national and international level, local communities and ecosystems will remain at high risk from the expansion of the global aquaculture industry," Naylor said.
The ENVIRONMENT report also was co-authored by Whitney L. Smith, a CESP research fellow. Research for the report was funded by the David and Lucile Packard Foundation.
CESP is a specialized research center within the Stanford Institute for International Studies that mobilizes a multidisciplinary network of scholars, students, policymakers and leaders to understand and help solve international environmental problems through science and policy research. The Stanford Fisheries Policy Project, a joint venture between the Stanford Law School and the universitys Hopkins Marine Station, works to improve the condition of the oceans through applied interdisciplinary research.
Ashley Dean is the assistant director for public affairs in the Stanford Center for Environmental Science and Policy.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
