The sudden deification of a man-eater…
Have you ever wondered how great whites became the
New Whale? And how, in the small
Australian coastal town of Ballina, a swarm of great white attacks
could be met, not with the proven solution of stringing a few
hundred metres of nets across each beach, but with government
hand-wringing and absurd solutions such as drone surveillance?
Vic Peddemors, the chief shark researcher at the NSW Department
of Primary Industries, is an example of the mindset that constantly
resists suggestions to make the ocean safer for people.
In a TEDx talk called “Sharks or humans, who should be
afraid?” in Canberra in 2012, he jokingly described
the two fatal attacks in Western Australia that year as a “bumper
season”. Some members of the audience nervously laughed along
with him. He added that the toll was an “anomaly” and “next year it
will be back down to the normal levels that we would expect”.
Peddemors’ reassuring prediction was incorrect. At least four
people have been killed by sharks in WA since then. Three
unexplained disappearances might also have been caused by sharks,
although we will never know.
Last year I emailed Peddemors, asking him if he regretted the
insensitivity of the “bumper season” remark, but he never
replied. Peddemors was making more predictions last week,
telling the Australia-wide youth radio station Triple J that
nets in Ballina would have an unacceptable toll on marine
mammals.
“He predicts that rolling them out on the north coast would kill
20 dolphins within weeks,” the station reported.
Queensland statistics suggest Peddemors is exaggerating. Only
eight dolphins were killed in that state’s 28 nets, spread out from
Cairns to the Gold Coast, in all of 2015. Peddemors also said
that great whites are “certainly not attracted” to humans. But a
horrific incident in South Africa in 2013 disputes this. A
fifteen-foot-plus great white took a snorkeler from the shallows at
Jeffreys Bay (where Australian pro surfer Mick Fanning was attacked
last year) into deeper water.
After the alarm was raised, a man on a kayak paddled out to try
to retrieve what was left of the victim’s body. But the shark would
not let the body go, despite the kayaker hitting it with his
oar.
There are many other incidents where the victim is never
recovered, which contradicts Peddemors’ claim that great whites are
not interested in killing or eating humans.
Glen Folkard, who survived an attack in Newcastle in 2014, says
he believes great whites retreat after making an initial strike and
simply wait for the victim to bleed to death, which explains why
some victims are given a brief opportunity to escape, as Folkard
himself did, albeit with injuries that still cause him physical and
psychological pain today.
Peddemors last week also participated in a video debate
organised by Coastalwatch, a surfing website. In it he gave a rare
insight into the objectives of the federal Great White Recovery
Plan, devised in 2002 and revised in 2012.
“Geneticists believe there were probably 30,000 white sharks in
the (Australian) population long before we arrived on this
continent, and that it was stable at that level for thousands of
generations,” he said. He estimated the current population is fewer
than 6000, implying that we are only a fifth of the way back to the
ideal population.
It’s curious that Peddemors is so confident of an estimate from
an unspecified period in history yet decades of research by him and
others has still not arrived at a definitive population figure
today.
Peddemors’ main strategy has been an expensive and potentially
dangerous program of tagging sharks. But the deleterious effects of
this strategy are considerable. Tags can be heard by the sharks’
prey; and they have been known to cause injury and irritation to
sharks.
Besides, a report by the West Australian Department of Fisheries
earlier this year made the startling discovery that great white
behaviour is “highly variable… white sharks were observed
travelling along the WA coast in both directions at most times of
the year”. It also found that “it is unlikely that a greater period
of data collection will generate an overall predictive model”.
While he continues to promote increased tagging in an unlikely
attempt to be able to predict shark behaviour, Peddemors’ advice to
surfers, according to Hack, is to buy a shark repellant.
“Stop asking the government, stop asking council, stop asking
everyone else, to look after your own safety, look after
yourself.”
If it sounds like satire, it isn’t.
Meanwhile, after two great white attacks at Ballina in a week,
the NSW government suddenly reversed it’s no-shark nets policy.
Sanity, sometimes prevails.
