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.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
