The Great Salmon Run: Competition Between Wild and Farmed Salmon, released by TRAFFIC, the wildlife trade monitoring network of World Wildlife Fund and IUCN-the World Conservation Union identifies two important trends that have remade the salmon industry in the last 25 years: farmed salmon has grown from just two percent of the world supply in 1980 to 65 percent in 2004.
About three-fourths of the fresh and frozen salmon consumed in the United States is now farmed. In response, the value of the North American wild fishery has plummeted, as indicated by the decline in the value of annual Alaska salmon catches from more than $800 million in the late 1980's to less than $300 million. The decline in value of wild salmon catches has had wide-ranging economic and social effects on wild salmon fishermen and fishing communities.
"Wild salmon could never supply the market demand being met by farmed salmon. A fundamental point of the report is that the debate should not be about wild versus farmed, but whether each method of production is being done right," says Dr. Gunnar Knapp, professor of economics at the University of Alaska, Anchorage, and one of the study's authors.
The report found that the rapid growth in farmed salmon has dramatically increased total salmon supply, changed the kinds of salmon products that are available, altered the timing of production and raised market quality standards. These changes have raised economic, environmental and trade questions. For example, how does wild salmon, which no longer provides the bulk of North America's salmon, remain a competitive product?
One of the report's recommendations is that Alaskan salmon producers expand the use of labeling provided by the Marine Stewardship Council (MSC) which conveys to consumers that wild salmon come from sustainable fisheries.
"Labeling helps consumers make informed choices," said Dr. Cathy Roheim, co-author of the study and professor of economics at the University of Rhode Island.
The report also recommends:
- harmonizing regulatory food safety standards;
- recognizing and mitigating environmental impacts of both farmed and wild salmon production;
- providing accurate and balanced information about salmon issues;
- collecting better data about seafood markets and consumers;
- and consider the role of hatcheries in wild salmon production.
"This report shines a light on a very complex industry that has a big impact on both people and the environment," said Jill Hepp of TRAFFIC North America. "Our goal is for this report to now be used by the industry and policy makers to protect wild salmon resources and the fishery that so many people depend on."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
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.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

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...
