Protected Corals Increase Fishing Profits

17.05.2010
The Wildlife Conservation Society today announced findings from a study showing that closures and gear restrictions implemented in fishing areas can increase fishery revenue and net profits.

The landmark findings, presented today at the Subsidiary Body on Scientific, Technical, and Technological Advice of the Convention on Biological Diversity held in Nairobi, Kenya, will help usher in a new era of acceptance for fishery management solutions that provide for local communities while protecting the world’s priority seascapes.

The extensive 12-year study recorded information on 27,000 fish caught within three fishery locations on Kenya’s coast: one abutting an area closed to fishing; a second located far from the closure area and with restrictions on seine nets in place; and a third open to fishing without restrictions and located far from closure areas. In the first area, results showed that fish migrating into the fishery from the closure area included more preferred species, as well as larger fish. These fish commanded higher prices per pound. The surprising effect of the closure was an increase in revenue to the fishers. Further, the study found that restrictions on the use of seine nets in the second area also increased fishery revenue.

The study, by Wildlife Conservation Society Senior Conservationist Tim McClanahan, will appear in the May online edition of the journal Conservation Biology. It is the first long-term study on the effects of fishery closures on fisher profits. The results indicated that the existing simplifications used in fisheries economic models tell only part of the story. By identifying the role that closures play on the types and size of fish caught, and the corresponding effect on pricing, McClanahan uncovered a more accurate and informative evaluation of fishers’ incomes – a discovery with potentially profound implications.

“Resistance to closures and gear restrictions from fishers and the fishing industry is based largely on the perception that these options are a threat to profits. These findings challenge those perceptions.” said McClanahan. By showing that prized species and larger fish are entering fisheries indirectly through the closures, we see that closures are a direct benefit to the fishers.”

The findings come as the Earth’s oceans are being fished beyond their limits and one third of all reef-building corals are threatened with extinction. Fishery closures are among the most effective solutions studied to protect reef areas and vital habitat for countless species to feed, grow and replenish their numbers—but are also perceived by fishers as a threat to profits.

McClanahan’s in-depth empirical study indicated no long-term loss to fishers and instead led to more support for the concept of closing fisheries. Fishers eventually realized compensation in the form of a larger and more valuable catch—and in some cases—higher net incomes.

“Evidence indicating that these management options provide a long-term income and profit boost for individual fishers provides great hope for the world’s oceans and coastal economies,” said Dr. Caleb McClennen, Director of Marine Conservation for WCS. “A disproportionately high percentage of the world’s marine biodiversity is situated adjacent to developing coastal nations, where sustainable economic development and poverty alleviation are top priorities.”

The findings demonstrated that when evaluating and informing fishery management options, an analysis on how fish pricing is affected by closures and gear restrictions is essential. In addition, the findings show that management options serving multiple bottom-line interests may be within closer reach than previously believed—in Kenya and elsewhere.

The Wildlife Conservation Society works to ensure protection of 90 percent of tropical coral reef biodiversity by improving conservation of priority seascapes in the Caribbean, Western Indian Ocean and the Coral Triangle. Critical support for this study was provided by the Tiffany & Co. Foundation, the Western Indian Ocean Marine Science Association and the World Bank.

In the United States, continued reauthorization of the Coral Reef Conservation Act and enhanced coordination and support from multilateral and federal institutions, such as the National Oceanic and Atmospheric Administration and the U.S. Agency for International Development, is critical to provide leadership assistance to the most vulnerable human populations in implementing innovative programs to address coastal poverty, the loss of marine biodiversity, and the imperative to adapt to the impacts of climate change.

The Wildlife Conservation Society saves wildlife and wild places worldwide. We do so through science, global conservation, education and the management of the world's largest system of urban wildlife parks, led by the flagship Bronx Zoo. Together these activities change attitudes towards nature and help people imagine wildlife and humans living in harmony. WCS is committed to this mission because it is essential to the integrity of life on Earth. Visit: www.wcs.org

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...
