Sharks are worth more in the ocean than in a bowl of soup, according to researchers from the University of British Columbia.

A new study, published today in Oryx – The International Journal of Conservation, shows that shark ecotourism currently generates more than US$314 million annually worldwide and is expected to more than double to US$780 million in the next 20 years.

In comparison, the landed value of global shark fisheries is currently US$630 million and has been in decline for the past decade. An estimated 38 million sharks are killed per year to feed the global fin trade alone.

"The emerging shark attracts nearly 600,000 shark watchers annually, directly supporting 10,000 jobs," says Andrés Cisneros-Montemayor, a PhD candidate with UBC's Fisheries Economics Research Unit and lead author of the study. "It is abundantly clear that leaving sharks in the ocean is worth much more than putting them on the menu."

"Sharks are slow to mature and produce few ," says Rashid Sumaila, senior author and director of UBC's Fisheries Centre. "The protection of live , especially through dedicated , can benefit a much wider economic spectrum while helping the species recover."

The research team from UBC, the University of Hawaii and Universidad Autónoma de Baja California Sur in Mexico examined shark fisheries and shark ecotourism data from 70 sites in 45 countries. Almost $124 million in dollars were generated annually in the Caribbean from shark tourism, supporting more than 5,000 jobs. In Australia and New Zealand, 29,000 shark watchers help generate almost $40 million in tourism expenditure a year.
