The Great Fiji Shark Count
This month,
Global Vision International (GVI) Fiji’s Marine Research and Conservation team were involvemed in the Great Fiji Shark Count.
The Great Fiji Shark Count encourages dive operators/ companies to record any
sightings of sharks, turtles or rays whilst out snorkelling, scuba diving or
fishing in Fiji.
The GVI Marine
team have incorporated this practice into our daily research and conservation
work. Each day we log between two to three dives at selected dive sites in the
Yasawas. During the dives we make note of any sightings of sharks, turtles or
rays, which species they were and how many of each were seen. All data is
recorded into a provided log book along with other information such as the site
name, the date, the time we entered and exited the water, water temperature,
water visibility, the maximum depth we reached, the habitat type (high profile
reef, low profile reef, sloping drop off, wall, ledge ect) whether anyone was
seen spear fishing at the site, whether there was any food added to the water
to attract fish, if any sharks were seen mating and if three or more baby
sharks were spotted.
Why is it important?
Globally, up to
90 million sharks are estimated to be killed every year. Commercial fishing
(shark finning) is the number one cause for the alarmingly high number of
deaths per year, as the demand for shark fins (used in the “delicacy” shark fin
soup) in heavily increasing particularly in the Asian markets. Over the past
few years alone it is estimated that shark populations have declined by 70 – 90%,
with such high percentages having devastating effects on our marine ecosystems.
Sharks are
highly mobile, only a few are seen at one time, making shark population data
quite difficult to collect. This is where the help of local communities/
companies such as GVI come into play. Also known as “Citizen Science” by having
lots of eyes surveying a large number of reefs data is able to be collected
across the whole of Fiji, in turn creating the first real picture of how many
sharks there are in Fiji and which species live where.
The Big Picture
Collecting real
and accurate data on Fiji shark populations is essential for the adequate
management of the species, and the information collected through The Great Fiji
Shark Count plays a huge role in supplying this data, not only for Fiji but
also for global surveys.
