Did you actually read what I typed Take it you had a bad day

the queensland nets dont normally account for the bigger sharks. The big ones are targeted by the use of baited drum lines.

Tigersharks are scavengers and opportunistic feeders. The eat anything but don't expel lots of energy hunting stuff down.

Great whites are hunters, used to preying on and attacking agile fast swimming mammals of similar size to humans, that look remarkably like seals whilst perched on a boogie board.

Overfishing doesn't affect great whites IMHO as they prefer high fat mammals like seals and whales. There are more of these now than ever due to protection so I would say that the increase in white issues would be more due to increasing whale and seal stocks than overfishing. Remember that whales were hunted pretty hard (humpbacks near extinction) for well over 100 years.

As for the theories of sharks becoming familiar with man due to cage diving, they document and research the sharks that they see. Possibly they would know if one of the sharks that they had seen cage diving off SA was involved in a fatality in perth if it was caught? Sharks there might not go to WA. You would think the researchers would be onto it if they did.

I don't really think the sharks are as smart some state they are. They actually have very small brains. There movements are far to random and most of there underwater patterns are navigated by magnetic fields and underwater highways not by memory.

Where the cage diving is located the sharks have been visiting the same sites for hundreds of years.
All the cage divers do is Bearly them up to the surface.

If you go to these spots and just anchor up you would be lucky to see one come to the boat or even surface.

I really doubt this industry entices sharks to feed on humans more along the lines it may feed them up on fresh tuna which in turn will make them more active for breeding cycles. These sharks do eat fish and as someone stated there main diet are seals well that's not exactly true it's more than likely optuinistic for sharks to grab a seal rather than a snapper or tuna.

Like I said how many attacks were there in the 1700s when water sports where non existent? There are less sharks, less food and more humans using the water now ....this is the only reason we see more attacks ...... And what has the Batavia got to do with this thread I have to wonder?

There are too many big sharks out there. In my book humans are more important than sharks.

Human population 7,100,868,651, we are not exactly endangered.

We loose a few through shark attacks, world wide about 100, world wide murder rate is about 460,000 (and that is not because we are hungry) not including wars. Maybe we need to cull our selves.

seems we are.

I was going to post a link to the theme song but this is better.

Maybe your new avatar Barbs?

Farrrk me it looks like dog, but.................

I agree with Razzonater and can relate to what he says. In Adelaide River, Topend, the jumping crocodile cruises are very popular. They started about mid 80's from memory. I used to love fishing in small dinghies in systems like this, but eventually stopped due to this hazard.

Quick question: Why is Perth lite up like a christmas tree on the link below ?. Is it because this is where the sharks are, or is it because only WA people are reporting sharks ?

It's cultural. My grandfather shifted to WA in the late 50s, our family sailed over to visit on the SS Oronsay. I remember my mother was amused that I spent the whole trip leaning over the back watching the wake. And when we got there the headlines in the paper were "3 foot shark in 2 feet of water at Cottesloe!" That made her laugh she speculated that surely they meant 3 foot in diameter? She was equally amused that it even made news in the paper. Swimmers often got chased out of the water in Victoria but it never made the newspapers. We stayed at Mt Pleasant on the Canning river.

Who in Perth used to make those little galvanised iron canoes back then? I thought they were pretty good, we didn't have them in Vic, never even got to paddle one though.

One species right to life versus another's right to recreation . Seems a little unbalanced certainly from the sharks percpective .

Dang some of you folk are just plain bubba gump dumb.

And for those who aren't...

This one's white...
Better watch out, it has it's eye on you.

I did the shark cage dive out of port lincoln this year and there was only 1 out of the 8 sharks we saw with a tag. With 40 tourists paying for the boat (and dec getting a decent slice) to see them you would also think they could be doing a lot more to study them. The second we dropped anchor one turned up even before burley was put in the water but then the sharks up here turn up behind the trawlers every night too.

Excellent turtle hunter clearly an indication that 7 out of 8 sharks that do come to the cage diving are not researched or tracked and also have learnt habits such as boat motor off, feeding time....
It's unbelievable that these learned habits are encouraged.
Do not think this is an attack on you as a person.
To dive with a great white is no doubt on many people's bucket list.
And unfortunately this is completely unregulated and encouraged.
There are two distinct breeding grounds for great whites in Australia with scientific proof of genetic difference in DNA, meaning that these sharks are taking learned habits with them.
One is in south oz in close proximity to port Lincoln and the other is in wa I will not post specifics as this will only encourage 'punters' to mess with there already increasingly learned habits....

It was one to tick off the bucket list although a few of the images in my head came back on the way home kiting the south coast.
Talking to the skipper it sounded very regulated with the sharks barely getting any food at all and it shows as the bigger sharks not spending any extra energy chasing the bait. As for them learning bad habits I see it as being similar to any fishing boat that has sharks follow (like trawlers) where the sharks know the sound of the individual boat not boats in general. There was a cray boat sitting at anchor near us with no signs of sharks around it.
It just seems like this opportunity to study them will be wasted but the govornment is willing to spend so much on helicopters searching the coast

Yeah, just as cute as those nice lookin' grizzly bears.

I wonder if it would make a good pet?

Do they need much to eat?

Safe? Yeah, sure, as long as you treat it with respect

Most animals when NOT on the brink of starvation or defending their young or 1/2 scared to death we're going to kill them for a laugh are fairly tame.
Humans are by far the most dangerous of animals bcos they'll f@ck you over for fun.

Yeah, right! As if. Tame? Like natural selection created? Yeah, they are all living in a magical fairy kingdom, with free food and rainbows everywhere.
