Sharks are increasing around Perth?

THE GREAT SHARK DEBATE
Australian Broadcasting Corporation

Reporter: Danielle Parry

An increasing number of shark sightings in Western Australia is raising alarm bells.

Transcript
TRACY BOWDEN, PRESENTER: While the east coast battles rising flood waters, the west is struggling with a heat wave and a different kind of threat.

A number of shark sightings have raised alarm bells and forced the evacuation of Perth's popular Trigg Island Beach.

Attacks are relatively rare, and fisheries authorities say they're yet to see any significant increase in the number of large sharks, since conservation efforts were stepped up in the 1990's.

But surfers and fishermen in Western Australia are telling a different story.

Danielle Parry reports.

DANIELLE PARRY, REPORTER: These extreme surfers regularly risk their lives riding some of the world's biggest breaks off WA's south-west coast. They use jet skis to reach waves as tall as buildings and deep water where sharks are known to lurk.

KERBY BROWN, SURFER: It's definitely in the back of your head, especially when you're just floating up behind the ski and we're on coloured boards. We're pretty much like lures. We're pretty much trawling around for sharks.

DANIELLE PARRY: Not much scares Kerby Brown, but on a recent expedition into the Southern Ocean, he was badly shaken by his first close encounter with an 18-foot great white shark.

KERBY BROWN: Yeah, I was sittin' on the jet ski, waiting for a wave, just dangling behind the wave and this huge fin, probably about that big (demonstrates size of fin with both hands) just came straight up in the front of the jet ski and everyone's seen it and just, like, jumped onto the jet ski as quick as they can, like, scrambled on. Everyone was freakin' out and then it just circled around and popped up a few time.

DANIELLE PARRY: Recent shark attacks closer to shore have had the Perth public on edge for weeks. A tour guide was recently mauled by a suspected great white while she was swimming with dolphins in shallow water south of the city. She survived, but only a few months earlier, a surfer wasn't so lucky. The young father was taken by a great white at Gracetown in the state's south-west.

HUGH EDWARDS, AUTHOR & SHARK EXPERT: Well I think human beings have always been fascinated with the creatures that can kill them. There's nothing like a fatality to make an imprint in the public mind. And every time people start to feel comfortable, there seems to be another one.

DANIELLE PARRY: Since those attacks, there's been a spate of sightings.

The site of this whale carcass feeding frenzy off Rottnest Island has only further fuelled Perth's shark fears.

RORY MCAULEY, WA DEPT OF FISHERIES: Whale carcasses are like shark magnets and they drift around the ocean putting out this scent behind them that appears to attract sharks from all around.

DANIELLE PARRY: Some locals suspect expanding whale and seal populations could be affecting shark behaviour and numbers, but experts say the jury is still out.

RORY MCAULEY: Whether the increase in the number of dead whales that some sharks species scavenge will actually increase the numbers of sharks and the population or whether they're just an attraction device, we really don't know.

DANIELLE PARRY: The display came as no surprise to many Perth fishermen, who say they're now seeing increasing numbers of large sharks close in to shore.

RAY YUKICH, FISHERMAN: I've been fishing for 50 years and we occasionally saw a large shark swimming around. But that was occasionally. Now we see them regularly. There might be anecdotal evidence, but it's there and you can ask any fisherman, they'll tell you. It's not just a few more sharks; it's a huge number of sharks.

DANIELLE PARRY: The Yukich family runs a rock lobster boat off the Perth coast. The summer lobster season has only just begun, but they're already seeing many large sharks coming in to eat the bait that's discarded from their pots. Ray Yukich used to fish for sharks and is amazed at how many he now sees.

RAY YUKICH: About four years ago, there seemed to be a change. The (inaudible) count with the baby lobster seemed to have disappeared that there've been very low settlement ever since then. At the same time, coinciding with that, there's been a large number of large sharks that appeared and been here constantly.

DANIELLE PARRY: He says the season before last set a new benchmark for large sharks.

RAY YUKICH: We fish from the opening season on 25th November till Australia Day on initially 26th January, we only had one day where we didn't see a large shark swimming around us and we had up to 10 sharks at a time.

DANIELLE PARRY: WA authorities say there's no hard evidence great white, tiger or whaler shark populations have significantly increased.

RORY MCAULEY: I certainly wouldn't discount any of those anecdotal reports because fishermen see what they see. They're the ones out on the water. They're the eyes and ears. But, what we're seeing in the data that we're getting from fisheries is that the rate of capture of white sharks is actually less than it was even 10 years ago.

DANIELLE PARRY: Authorities on the east coast are also sceptical.

VIC PEDDEMORS, NSW DEPT PRIMARY INDUSTRIES: This year so far we haven't had many reports of fishers of large sharks being close to the coast on the east coast. White sharks seem to be slowly showing an increase, by it's still very early days. They've only been protected since the '90s and it takes a long time.

DANIELLE PARRY: WA authorities hope a new tagging project of Perth will give them a better handle on the shark population.

These listening stations can record the presence of sharks that have been electronically tagged by scientists around the country and then send warnings to nearby beaches.'

RORY MCAULEY: We have about 100 sharks that are potentially detectable by this array at the moment. It is early days and we expect to have the results in by the end of 2011.

DANIELLE PARRY: In the meantime, as the public heads to the beach this summer, experts are urging people to keep the shark risk in perspective.

RORY MCAULEY: If you look at the rate of fatal attacks over the past 10 years compared to the previous 10 years, the numbers are almost identical. So, again, there doesn't appear to have been an increase in the rate of fatal shark attacks, particularly when you consider that there are more people getting into the water these days.

HUGH EDWARDS: There is one sure-fire way of avoiding shark attack and that is: stick to standing under a shower. That's all you can do.

TRACY BOWDEN: That report from Danielle Parry in Perth.

The above article is by no means saying that sharks no longer need to be saved, etc. but is just an article to ponder.

Similar stories are there for California and Cape town too.

Humans have a tendency to "know" what is right and usually end up messing up thing.

1. We kill sharks for fins in open sea, then decide to conserve them at marine park and areas close to shore. Now there's more attacks on humans. :violent1:


2. We removed the triton shell for commercial gains and now have a crown of thorns problem. We remove the crown of thorns and will most probably end up messing something else.

3. We exploited the leather back turtles in Rantau Abang and still consume & sell turtle eggs. Now I see volunteers patroling beaches chasing away the monitor lizard, birds, etc from doing what they do naturally which is to seek the nest and feed on the eggs. (But allow the "authorities" to collect eggs the next morning to take to the "hatchery".  [-( [-( [-()


The list goes on and on but I guess you guys get the point.

Well, i have to say that Sharks is a predatory animal just like any other animal such as Lion n Tiger. Tiger kill Human too, n sad things is that it needed to be protected... :violent1:

Statistic Human killed by :
Elephant & Tiger    100
Crocodiles            200
Flies                    10,000
Illegal Drugs          22,000
Road Accidents    1.2 millions
Mosquito              1.5 millions
Starvation            8 millions
Defective Toaster  800
Vending Machine  13
Sharks                5

Human killing more than 73 millions Sharks annually...

well, this is the statistic, I m sure you have heard of Rob Stewart from SharkWater :
