It is easy to catch great whites, bait needs to be seal whale or tuna.
Easy very easy.

I said i wouldnt post but I cannot contain it any longer.
In western australia all cray boats could use shark hooks on the floats, so a few hundred shark hooks in the water every day spread through a,b,c fishing zones at a minimum and daily.
Fisheries stopped this about ten years ago.........
In western australia we used to have 12-15 shark net fishing boats up until 10-15 years ago...
Fisheries made it economically viable to maintain. As of last year I think there were only one or two guys left.

Great whites are apex predators and fisheries allow cage diving which trains them and they relate humans to food and boat noise to food.
They are rewarded with food and in doing so become complacent of humans trained and learn to relate people to food.
Fisheries allow this.
When the ban on great whites was put into effect there were no scientific reasons or facts to do so.
It takes a great white twenty years to build up the jaw compressive strength to eat a mammal which could be classed as seal or human.
Unfortunately these have been trained to do so and in the last few attacks many of the victims were eaten.
Earing a whole person is not an accident, nor is it a case of mistaken odentity.
To summarise ot is not a cull it is fishing, do i agree with fishing for sharks, absolutely it was my youth and provided my family with income passed through several generations.
Fisheries and the epa have no idea absolutely none.
They never knew how many sharks were there when they put them in protection and now have less of a xlue than ever. There is no science and every phd educated person with a voice just wants to keep being funded millions and millions for developing things that will never be finalised cause that will dey up the funding.
The shark shield does not work and the way it is operated is proven to attract sharks in many cases.
In the case of the divers attacked it is likely they had these on until they did not work in which case they turned them off.............
Unfortunately the people eaten cannot relay this part of their story.
It will only get worse while cage diving and studies and fisheries do not allow fishing.
It is not culling it is fishing.

Was it that one where he only turned it on when he wanted to surface?

I think one of the important things to note is its supposed to distract the shark when its looking around, but once its decided to attack its not enough of a deterrent to stop it... so it needs to be turned on all the time.

The one attack on Peter Clarke he had the electrode attached to his air hose. The air hose needs to sink to be active. Floating on the surface rendered it useless.

The second attack was the one were it was not turned on. Sadly though people chose to ignore these facts when saying these units don't work.

Its kinda like saying he died in a car crash, the seat belt didn't work, even though he wasn't wearing it

Testing has found that these units will work 9 out of 10 times, even in a motivated attack, but then again some people will still argue the world is flat

When that little switch inside a GW or Tiger sharks brain switches to the hunger/hunt mode they will eat or at least take an exploratory bite of anything living or dead that may be edible and has ventured into their "zone". I don't for one second believe that anything has been invented that will stop a full blown attack from a hungry GWS or a "gentle mouthing" from a big hungry tiger.

The 'Big uns' are about in greater numbers since protection and the gradual build up of whale numbers, water sports are attracting more and more participants every years, the odds of encountering a hungry shark whilst participating in you preferred marine pastime is increasing, still remote but the recent figures on attacks both on the east and west coasts indicate this is occurring.

It is of no consequence to a victim of a fatal attack to hunt down and kill a suspect, it may go some way to alleviating public angst, but (IMO) to use drum lines in an area where an attack has occurred is seriously flawed, you are not seeking the culprit but using drum lines festooned with smelly baits to attract as many sharks, from as far away as possible into a "killing zone".

I am not sold on the ideal of netting the beaches, I don't know how effective they are, I'm aware of the concerns re by catch, cost, weather limitations associated with nets.

My suggestion would be an "open season" on GWS's, (to coincide with the whale migration), a season where professionals and amateurs can take them, maybe organise a GWS "Tournament" in the West and the East, where fish over 2.5 or 3 mtrs MUST be weighed in, thus removing large specimens from the system without depleting the species too much?

Yes I know a 2.5 mtr GWS can bite my leg off, I also know a 4 mtr one can bite me in half.
Fatal attacks are becoming far too common and something needs to be done to make our coastal waters just that little bit safer for all users.

Razz i was wondering is you could show any form of proof that sharks are attracted to electronic devices

Its just that the power rating of these units cannot pass more than about 15m, if they could, then the game would be unreal as a larger barrier could be created..But sadly its been explained to me the simple law of physics says it cant be done, thats why I'm curious on your proof that physics is wrong

You are correct jb within the field of 15 metres it will repulse sharks. However sharks are well aware of electrical disturbance within the water prior to being within 15 metres and up too several hundred metres away the electrical field will attract them.
If said shark has already decided to attack prior to entering the 15 metre range and moves between 24 and 35 kmh it is not enough time to put the brakes on or alter mechanism of feeding. (Rolled eyes and mouth open )
Please see link below for some science in regards to sensitivity of electrical fields.

How much do you sell them for JB?
