Alternative animal feed part of global fisheries crisis fix

19.11.2009
Finding alternative feed sources for chickens, pigs and other farm animals will significantly reduce pressure on the world's dwindling fisheries while contributing positively to climate change, according to University of British Columbia researchers.

"Thirty million tons – or 36 per cent – of the world's total fisheries catch each year is currently ground up into fishmeal and oil to feed farmed fish, chickens and pigs," says UBC fisheries researcher Daniel Pauly, co-author of the Oryx: The International Journal of Conservation article, published online this week.

"Meanwhile, 25 per cent of infants in Peru – which produces half of the world's fishmeal using anchovies – are malnourished," says Pauly.

In the Oryx article, nine of the world's leading fisheries and conservation researchers – including four from UBC – reviewed the effectiveness of past conservation campaigns and propose new strategies to effect swifter and larger-scale changes.

"Globally, pigs and chickens alone consume six times the amount of seafood as US consumers and twice that of Japan," says lead author Jennifer Jacquet, a post-doctoral fellow at UBC's Fisheries Centre. "Ultimately these farm animals have a greater impact on our seafood supplies than the most successful seafood certification program."

"We should work to eliminate the use of tasty fish for livestock production. It's a waste," says Pauly. "Plus, it is not what pigs or chickens naturally eat. When is the last time you saw a chicken fishing?"

Many sustainable seafood campaigns focus on consumers but ignore large-scale market impacts – such as farming demand for fishmeal – and have failed to reach their goals, say the study's authors, which include Enric Sala of the National Geographic Society and Rashid Sumaila and Tony Pitcher of UBC.

After pioneering and distributing more than one million seafood wallet cards – pocket-sized guides that advise consumers of ocean-friendly seafood, the Monterey Bay Aquarium conducted a study that revealed no overall change in the market and that fishing pressures had not decreased for targeted species, the study points out.

"Sustainable seafood certification programs such as wallet cards have raised consumer awareness but are far less effective than targeting mega supermarket chains such as Walmart, Whole Foods and Loblaw through a combination of positive and negative publicity campaigns," says Jacquet, adding that more than 60 per cent of seafood in Canada and half the seafood in the U.S. is sold through supermarkets.

The authors also suggest establishing international standards for labeling sustainable seafood, eliminating harmful fisheries subsidies and leveraging momentum for fisheries conservation through existing global concerns for climate change.

"Global fisheries consume 13 billion gallons of fuel each year just to catch and land fish," says Jacquet. "That's more gas than 22 million cars would use. Energy use would be much higher if we include the fuel used to ship fish further for processing and to market. No discussion of the overall impact of fisheries would be complete without clarifying its contribution to greenhouse gas emissions and climate change."

"Overall, we'd like to encourage people to engage more as citizens – as they have with the global climate change movement – and less as mere consumers," said Pauly. "Big problems like overfishing require efforts to be directed at big change."

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

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...

Im Focus: Visual intelligence is not the same as IQ

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...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

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....

Im Focus: Researchers Develop Data Bus for Quantum Computer

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,...
