'Best hope at sustainable fisheries' short-changed by conservation efforts: UBC researchers

28.08.2008
Small scale fisheries produce as much annual catch for human consumption and use less than one-eighth the fuel as their industrial counterparts, but they are dealt a double-whammy by well-intentioned eco-labelling initiatives and ill-conceived fuel subsidies, according to a University of British Columbia study.

Small-scale fisheries are characterized as fishers operating in boats 15 metres or shorter.

“They are our best hope at sustainable fisheries,” says Daniel Pauly, Director of the UBC Fisheries Centre and co-author of a study published in the current issue of the journal Conservation Biology.

The study shows the amount of subsides large-scale, industrial fisheries receive versus small-scale, coastal fisheries. For instance, the average large-scale fisherman receives nearly 200 times the fuel subsidy that the average small-scale fisherman receives.

“This is because small scale fisheries employ more than 12 million people world-wide, compared to half a million in the industrial sector,” says Jennifer Jacquet, study co-author and a PhD Candidate in the UBC Fisheries Centre. “And because small-scale fisheries use less fuel to catch fish.”

An illustration comparing small- and large-scale fisheries is available at Sea Around Us.

“Small-scale fisheries use fishing gear that are more selective and far less destructive to deep sea environments,” says Jacquet. “As a result they discard very little unwanted fish and almost all of their catch is used for human consumption.”

Large-scale fisheries, on the other hand, typically do not target species for direct human consumption and discard an estimated 8-20 million tonnes of unwanted dead fish each year and reduces another 35 million tonnes of their annual catch to fishmeal.

Over the past decade, market-based sustainable seafood initiatives such as eco-labelling have been the predominant strategy for curtailing demand of dwindling fish stocks. The U.S. conservation community alone invested $37 million between 1999 to 2004 to promote certification and “wallet cards” to encourage consumers to purchase seafood caught using sustainable practices.

“For the amount of resources invested, we haven’t seen significant decrease in demand for species for which the global stocks are on the edge of collapse,” says Pauly. “Market-based initiatives, while well-intentioned, unduly discriminate against small scale fishers for their lack of resources to provide data for certification.”

Furthermore, small fishers simply can’t compete on the open market with large fleets. Rashid Sumaila, also of the UBC Fisheries Centre, estimates that governments worldwide subsidize $30-34 billion a year in fishing operations, of which $25-27 billion go to large-scale fleets.

“It’s an unfair disadvantage that in any other industry would have had people up in arms,” says Jacquet. “But small-scale fishers are often in developing countries and have very little political influence.”

Pauly and Jaquet say eliminating government subsidies is the most effective strategy towards significantly reducing pressure on vulnerable global fish stocks.

“Without subsidies, most large-scale fishing operations will be economically unviable,” says Jacquet. “Small scale fishers will have a better chance of thriving in local markets, and global fish stocks will have an opportunity to rebound.”

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
