all bombora's points are good

the 4.6m white I helped dissect was only 15-17 years old...but I get what you meant.

it broke the crane on the shark fisherman's boat, and had to be cut in half to transport.
don't know how much it weighed, but over a tonne.
I fit through the jaws without touching the sides.

Sounds like the ultimate job you have there, Kaboo. What exactly is your job description?

Why do people - mainly sufers - discriminate that there is a difference between culling/ killing sharks, as opposed to Dingo's on Fraser Island?

If a cat enters my yard, and my dog being a dog eats the said cat, the council come and declare my dog dangerous and he risks being put down due to this. I know a couple who had their dog put down on it's first offence, so it does happen.

Yet a GW will eat a person - and in the case of the guy near perth who was swimming and taken - the shark responisble will be followed for two days and one night, and we let it go based on ... what, exactly? Are they endangered? No. Are dingo's? Hell yes. The purest purebreed dingos only exist on Fraser Island and we have a yearly cull to meet an undeclared quota decided by some politician who's never had sand on his feet.

I understand people abiding by the whole we are their territory bit ... I wonder if those guys have a family member or close friend taken by a white, change their stance on the issue?

A few stories of guys dying on the beach asking that they not be hunted down as well mate.

Know where you're coming from, hope I'm never in the position.

In light of the recent fatal shark attack at Margs, ive thought long and hard about it and had to make a tough decision for the sake of my personal safety. So...Ive decided to start surfing with guys who cant paddle as quick as me....

that was about 7 jobs ago...
I worked in a shark ecology lab, specialising in sensory ecology (big sharks and gamefish) and looking at what they ate (small sharks and rays).
You haven't really done a risk assessment until you fill out one for catching sharks at night in a seine net in a fishing channel. :)

you're actually better off learning how to paddle smoothly, it's the vibrations that appear to dictate whether a shark is just curious or willing to investigate further. You'll still feel like a wounded fish to them anyway, we're woefully inefficient at moving through water.

and not surfing at dusk, near headlands, rivermouths, murky water, fish activity, steep dropoffs etc. etc.
i.e. anywhere or anytime there's good surf.

in fact, everyone should give up right now until i've made sure it's safe! will report back in a decade or so...

Ive thought about doning one of these Shark Repllent Stickers on my surfboard, however carrying around somthing that looks like a dead zebra under my arm would probably make me lion bait... :roll:

Bombora is on the money

In my area up to a few years ago the juvenile GW's would move in and out with the mullet and salmon, but now there is almost no lull between the travel seasons and hence the juveniles have become permanent fixtures. I wonder at what size of these sharks does the energy expended in catching fish exceed the energy produced by the feed and therefore necessitate a supplement of mammal. There are seals in our area, and their numbers are gowing as well for the same reasons as the sharks, but I think their prescence will only ensure permanency of not only juveniles but big bastards too.

I reckon the other thing that has increased shark numbers is the increase in water quality off coastal cities that has taken place over recent years due to better effluent treatment and de-industrialisation. I understand that Sharks don't like pollution as it messes with their skin hosted sensory system and this has resulted in increased shark numbers closer to shore, where the mullet and salmon are waiting.

Where do I stand on culling? Don't give a dam either way. Although if one ate one of my kids I'd chase the bastard down. I think it is important to preserve the bottom of the food chain more than the top, especially when man has replaced sharks as the top marine predator. Remember the pilchard kill that happened about 10 years ago? we've only just started to recover from that debarcle, this was the first time since then that we've had a reasonable tailor & bonito season and that is due to baitfish recovery.....protecting sharks has no impact on that. (unless you subscribe to the theory that if you protect sharks as the top of the food chain you therefore must remove man's involvement as the sharks replacement..... shit now my brain hurts)
Get off the computer & go outside there's better things to do out there.

Fck this debate is depressing. Almost as bad as the election!
If you are a surfer then you are in the OCEAN! Creatures live there that might harm you. If you're not up for that then stay out of the OCEAN!
There's a lot of snakes in Australia and spiders that might kill you - should we wipe them out? Hang on , people die from bee stings - wipe them out too? Fckn magpie swooped me the other day on my pushie, I could have crashed and died - kill them?
What about tigers in India, lions in Africa, bears in Alaska, elephants in Thailand - all potentially dangerous - kill 'em?
The entire planet is one symbiotic entity. Dont think you can wipe out apex predators and everything's going to be cool.

The problem lies with whoever is responsible for the beach protection measures. The shark nets work - to a point. And thats all they are meant to do. They were never going to keep all sharks out period. Short of enclosing off entire stretches of coastline with netting (which would start a whole host of problems), I dont see how they are going to stop sharks and humans coming into contact with each other.

The shark sheild stystem is an interesting one. I think this will be the way of the future to deter sharks.....some kind of electronic impulse that only effects the sharks and not other marine life.

At the end of the day however, attacks on humans are still extremely rare given how many punters are in the water all year round. I think at the end of the day, we need to figure out way in which we can co-exist and the shark sheild system is on the right track IMO.

I remember trialing the shark shield system off straddie a few years ago. All I got was electric shocks from it. The unit was super chunky, and heavy. I was only swimming with it, and at the time I couldn't imagine surfing with it. At times the shocks would be debillitating ... It actually got me thinking I'd rather take my chances with the bloody shark.

I'm sure they've refined the model by now. But still ... I dunno if I'd surf known GW hotspots relying on it to bail me out.

I know Fong's reaction will make me regret saying this, but it was in Qld.

You can paint your board however you like, it won't do much. Sharks that eat big prey, i.e. tigers and whites mainly, tend to strike from below as they aren't as agile as their prey so they need to knock it out of whack. Tigers try and hit the side of the turtle to flip it over. They basically just see a silhouette.
Which is why most fish are dark on the top (blend into the bottom/depths) and lighter underneath (blend better into the light from above.
So white's probably a better option, don't get any sprays!

Sharkshield won't do much either. Sharks don't like electrical impulses, that much is true. If it was just curious, it might leave the area. But once a shark is on final approach it isn't going to turn away because of a tingling in it's shnozz.
There was a uni student killed while using a Sharkshield off Sth Oz in the last year or so...think there was a bit of debate about whether it was working properly or not.

Apparently, the best way to stop a shark that is actually trying to eat you is to jump off the board and hold it out above your head, to make yourself look as long as possible. That way the shark will think you're bigger than them and turn away.
I've only met one person mental enough to do this when push came to shove. :shock:

And surfers very rarely see the shark that attacks them. Divers occasionally do, but it still doesn't help much.

Braithy, if you're on Straddie, head to the Rufus King fish shop at Amity and ask to see the stuff in the freezer.

Wow, alakaboo. You are like wikipedia. I hear you, the problem is the sharks you don't see until you feel them.

I'll be at Straddie this Xmas, so I'll pop into Rufus and take a look. Although I got a fair idea what I'll be seeing.

I have a photo somewhere from a reader when I was working at ASL, it was the GW hislop caught in moreton bay. Deadset the size of a kombi wagon. i reckon 4 or 5 adults could fit in its jaws at the same time.
