Shark deaths hit two-decade high worldwide in 2011

Australia had three shark attack fatalities and there were two each in
Reunion, the Seychelles and South Africa, and one each in Costa Rica, Kenya
and New Caledonia.

The average global fatality rate for the last decade was just under 7 per
cent, and it rose to 16 per cent last year. Excluding the United States,
which had 29 shark attacks but no deaths, the international fatality rate
averaged 25 per cent in 2011, Burgess said.

“We’ve had a decade-long decline in the number of attacks and a continued
decline in the fatality rate in the U.S.,” Burgess said. “But last
year’s slight increase in non-U.S. attacks resulted in a higher death rate.
One in four people who were attacked outside the U.S. died.”

Other countries with multiple non-fatal attacks included Australia with 11,
South Africa with five and Reunion with four. Indonesia, Mexico and Russia
had three each, and the Seychelles and Brazil had two each.

While the higher number of fatalities worldwide came as a surprise, the drop
in the number of U.S. attacks follows a 10-year decline, Burgess said.

“There has to be a cause for that. People might argue there’s less
sharks, but since the late 1990s, populations have begun a slow recovery. By
contrast, the number of attacks in the United States and Florida suggests
there’s been a reduced use of these waters,” he said.

With its long coastline and year-round aquatic recreation climate, Florida
historically leads the United States in shark attacks, and last year was no
exception. The state had 11 of the 29 U.S. attacks.

Six of them occurred in Volusia County on the state’s central Atlantic coast,
a popular surfing area, but that was the lowest number there since 2004,
when there were three.

“It’s a good news/bad news situation,” Burgess said. “From the
U.S. perspective, things have never been better, our attack and fatality
rates continue to decline. But if it’s a reflection of the downturn in the
economy, it might suggest that other areas have made a real push to get into
the tourism market.”

The next step to reducing the number of fatalities is creating emergency plans
for those alternative areas, said Burgess, who has been invited to work on
developing a response plan in Reunion Island, in the Indian Ocean.

“Ironically, in this very foreign environment that has animals and plants
that can do us harm, we often don’t seem to exhibit any concern at all, we
just jump in,” Burgess said.

Surfers were the most affected group, accounting for about 60 per cent of
unprovoked attacks, largely due to the nature of the activity. Swimmers
experienced 35 per cent of attacks, followed by divers with about 5 per
cent.

Humans are not part of the sharks’ preferred diet, but those splashing around
on the water’s surface can be mistaken for normal shark prey such as fish,
turtles or seals. Burgess also pointed out that humans in wetsuits can be
mistaken for seals by the sharks.

“When you’re inside the water, there’s much less chance of sharks making
a mistake because both parties can see each other,” Burgess said. “Surfing
involves a lot of swimming, kicking and splashing.”
