Conservation dollars and sense

A case for shark conservation through ecotourism

Shark populations over the last 50 years have decreased dramatically. From habitat degradation to overfishing and finning, human activities have affected their populations and made certain species all but disappear.

A new article in Current Issues in Tourism by Austin J. Gallagher and Dr. Neil Hammerschlag of the R.J. Dunlap Marine Conservation Program at the University of Miami study the impact of these apex predators on coastal economies and the importance of including conservation efforts in long term management plans.

The team collected data from a total of 376 shark ecotour operations across 83 locations and 8 geographic regions. Oceania, The Greater Caribbean and North America ranked at the top for highest proportion of different locations offering shark tour services, and the Bahamas alone contained over 70% of all shark ecotourism in the Greater Caribbean and generated over $78 million in revenue in 2007. The Maldives saw similar numbers, and in 2010 banned shark fishing due to shark-based ecotourism contributing and estimated >30% towards their GDP.

"We know that for many countries, sharks are an important piece of the economy -- in this study we wanted to examine their value as a recreational resource in a new and refreshing way by taking a global perspective," said Gallagher.

"It makes total economic sense for us to protect these resources, whether you are in charge of a coral atoll somewhere in Indonesia or working off the coast of New England—if the sharks can remain, the divers will follow and livelihoods can flourish."

According to the study, a single reef shark could be valued at $73 a day alive, as opposed to the one-time value of a set of shark fins used for shark fin soup at $50. Over the course of that same shark's life, it could be worth more than $200,000 using a conservative 15-year life cycle. The study also documented trends by species, and found that reef sharks and whale sharks are among the most well-represented in the ecotourism industry.

"Our study clearly shows that, economically speaking, sharks are worth more alive than dead; however, sharks are also ecologically important, helping maintain the balance and health of our oceans," says Hammerschlag.

Sharks reproduce very slowly, so even modest amounts of fishing can negatively impact local populations. But with appropriate conservation policies, sharks can begin their recovery, a road that could be both enjoyable and profitable through ecotourism.

"After the 1975 release of the movie JAWS, the general public felt that 'the only good shark was a dead shark,' however in the thirty years that have followed, this mentality has changed. A growing number of people are turning their fear into fascination and want to continue to see sharks in the wild," said Hammerschlag.

About the University of Miami and the RJ Dunlap Marine Conservation Program

The University of Miami is the largest private research institution in the southeastern United States. The University's mission is to provide quality education, attract and retain outstanding students, support the faculty and their research, and build an endowment for University initiatives.

Founded in 2009, the R.J. Dunlap Marine Conservation Program is a joint program of the Rosenstiel School of Marine & Atmospheric Science and the Leonard and Jayne Abess Center for Ecosystem Science and Policy at the University of Miami. The Rosenstiel School offers one of largest, most comprehensive marine and atmospheric programs in the nation. The Abess Center encourages innovative interdisciplinary initiatives that bridge the gap between hard science and environmental policy.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
