James Cook University (JCU) and Australian Institute of Marine Science (AIMS) researchers have joined a world-first, global effort to survey shark numbers in coral reef environments.
The three-year survey of sharks and rays is the largest of its kind and is designed to provide fundamental data essential to building effective conservation programs.
JCU researcher and Director of the Centre for Sustainable Tropical Fisheries, Professor Colin Simpfendorfer said sharks are facing growing threats in the world’s oceans.
“Globally a quarter of shark and ray species are facing an elevated threat of extinction,” said Professor Simpfendorfer. “This research will help better understand the status of sharks and guide decisions about how to better protect them.”
The Global FinPrint survey is sponsored by Vulcan Inc., a Paul G. Allen company in the United States.
The research team is led by Dr Demian Chapman of Stony Brook University in the US, and also includes Dr Colin Simpfendorfer, Drs Michelle Heupel, Aaron MacNeil and Mark Meekan from AIMS, and Dr Mike Heithaus from Florida International University.
The survey portion of the Global FinPrint initiative will use baited remote underwater video (BRUVs) to survey sharks, rays and other marine life in coral reef ecosystem.
The team said a lack of comprehensive, up-to-date data hinders efforts to protect and replenish shark populations.
“This three year study is important for conservation as pressures on shark and ray populations increase. These underwater surveys will gather underwater video data on an unprecedented global scale that will dramatically increase what we know about reef shark populations,” said Dr Michelle Heupel.
Video surveys will be undertaken in more than 400 locations across three key geographic regions: Indo-Pacific, tropical western Atlantic, and southern and eastern Africa and Indian Ocean islands.
The new data will be consolidated with thousands of hours of existing video to form a single dataset, producing the first global standardised survey of sharks, rays and skates in coral reef environments.
Dr Mark Meekan noted that: “better management of sharks and rays starts with better information about where and when they occur, so that we can target mitigation and protect the areas that are critical habitats.”
The survey will also assist in understanding how marine ecosystems are affected in the absence of sharks. "Although sharks are among the most widespread predators in the ocean, we understand remarkably little about their overall role in ocean ecosystems," said Dr Aaron MacNeil.
Survey data will be made available through an open-access, database platform created by Vulcan’s technology development team and will include information on species density, habitats and diversity trends.
Researchers, policy makers, international governments and others will be able use this database to help inform conservation priorities, such as identifying and protecting areas with large or important shark populations, and to better understand the ecological importance of sharks as apex predators.
