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.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
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...
