Why does anyone want great whites around? this puzzles me, what benefits does the world get from having GWS? look at the benefits off wiping the GWS from the face of the Earth, safer for swimmers and surfers, we give the poor seals a break and more snapper and Tuna for us to catch and eat. the list goes on and on.....

 

The Apex predator theory biologists sprout is questionable and to me as believable as global warming/climate change (insert whatever name "climate scientists" decide to call climate today to milk money from the Government), the megalodon shark which apparently used to prey on GWS or its ancestors became extinct and the ocean fishery and whites didn't collapse, the white population has exploded because whites lost their apex foe's and need more predators. 

 

Wow.  :brickwall:

 

Surely this is a joke?

Are sharks not a problem at all to you? I'm talking about everyone, people are going to keep going in the water and we can't stop that unless a major disaster occurs. So instead of telling people to stop going in the water or get a shark shield (which almost no body will do) we need to work around that and create a solution to protect people from sharks whilst in the water. We (society) have created a huge problem with sharks. So what they kill less people then smoking does, it's the media that makes it terrible. Millions of people die each year from smoking, and still a huge portion of the population still smoke. If as many people died from sharks each year as much as people die from smoking, people would very rarely enter the water. Not every person is educated on this planet, it doesn't matter that smoking is a much bigger killer than sharks, the media are still going to make a HUUGGE deal about one shark attack. And we've got too embrace that, it's not like you can just write a letter to the media saying "stop reporting shark attacks and instead report bigger issues."

I don't even know where to start in response to that.

 

No, sharks aren't a problem to me... I swim at the beach EVERY week in summer with my 5 kids.

I kayak... a lot... and nope, not a problem.

Have a look at the list... The vast majority are surfers, body boarders and divers... Take them out of the equation and what risk is there to the uneducated masses of beach goers?

So my question to you is....

What risk do sharks pose to you personally? 

 

fairy the media. Dont like it, Stop watching and listening and you will be way better off. Let them prattle on... Why should we let lies and dramatic fiction shape the destiny of a species or government policy? 

 

Look how many people go swimming at beaches... It doesn't seem there is much risk to them according to the link above. So that means the money you propose spending is spent to protect a few surfers and divers... Not that they're not important but its not money well spent. Put the money to something with more bang for buck.

that is the most ignorant and outrageous thing I've read on this topic.....Why stop there let's kill off the lion , tiger population as well while we at it we might as well just kill off pandas too cos they do nothing for nature either.
You know we as a species are to blame for most the problems you are saying would be Beneficial if GWS were killed off.

 

humans are basically the apex predator on land - do you know if humans disappeared from the planet today... scientists and biologists all predict the worlds animals will once again flourish within 5 years..... dens statement has a lot of merit - we need to bring back the megalodon shark to eat the GWS :) .... as the top apex predator disappears for whatever reason then the next in line will experience a population explosion - thats just plain common sense... if GWS disappeared then tiger sharks and other species will pick up where GWS left off... size restrictions of the next apex predator will obviously permit the survival of some animals GWS would have eaten... more fur seals and sealions... their population explodes - then suddenly we have a seal/sealion problem...  i dont think messing with nature is the solution... removing one species upsets natures balance... nature has a way of balancing its creatures... almost like supply and demand but in a different format.... bumper season of baitfish leads to bumper season of salmon leads to bumper season of seals/sealions leads to bumper season of GWS..... when theres a famine of bait fish then the rest of the food chain follows..... 

 

moral of the story - every pcs member needs to catch their bag limit of salmon every day to prevent GWS numbers from exploding :)

Correct, there are many more shark attacks on surfers and divers etc. but what I'm trying to say is that when I was up on a station near coral bay, I saw so many sharks that when I went for a swim, I wouldn't go more than 5 meters out. As I said before, I was spear fishing just 20 meters out and a 3 meter bronze whaler swam past me (I hadn't even shot a fish). My point is that this is a case of an explosion in sharks and could very easily occur in the Perth waters at the rate we're going.

You were in a known shark hotspot....

Why not just swim in croc infested rivers too?
What can the government do about boofheads putting themselves directly in harms way?
So you jumped in the water to prey on fish, then you squeal because you saw a fish that was big and had teeth.
A shark is a hazardous creature like a snake or a lion or whatever. If you decide to frolic in the meadow with a pride of lions you're gonna get eaten and that's your fault! Lions aren't a risk if you take simple measures to protect yourself, same with sharks and the same with smoking and the same with any other hazardous situation you encounter.

Do you not understand that the shark population is growing? It could easily happen here in Perth. Like den stated before, when he was a kid sharks were practically unheard of, what do you think it will be like in another 50 years time?

You have your views and I have mine, I'm exiting from this arguement now.

I see it as population control. Human population control that is, there are way to many inconsiderate idiotic people in the world today, this is natures way of balancing the tables. Or it could be the Darwin theory playing out.

While in Port Lincoln I partook in the cage dives with the great whites that they do 5 hrs boat ride out in the islands there.  It was interesting talking to the boat tour operators that have been there for decades and their take of the shark issues (this was three years ago), this is what they said when quizzed about the boom in population....  

 

-  In the 80's the white sharks were protected with out an actual population survey being done to establish if they were endangered/threatened/etc.

-  The great whites need to be 5m long to breed and that happens at about 20 years of age.  The initially protected sharks are breeding for the past 15 years and the baby sharks from those protected ones are now breeding (compounding interest any one?)

-  They used to think the sharks needed to eat a mammal a week to maintain metabolic activity.  They now know by tracking tagged sharks that they will do a loop from the Neptune Islands in south aust, to perth, to exmouth, back to perth, across to south Africa, back to Neptune Islands in south aust.  They do that loop TWICE PER YEAR and need to eat a mammal a day to keep that level of metabolic activity.  So that is a seal (who's food is being over fished) or another mammal.

-  Over the 20 years they had operated it went from one boat taking half hour to get a shark on the  boat to 5 boats with 5 sharks on it before the anchor hits the ground.  Perhaps they are training sharks to interact with people or perhaps the sharks food is dwindling and they are hungry as F.

 

I never agreed with the shark diving tours but figured if they were shut down I would like to of tried it.  I had hoped that when the sharks attacked the cage you would have some prewarning that a freight train with teeth was about to hit you but above the surface, not a ripple.  You'd lose your leg before you could brown ink your self to get away.  I had also hoped they would be beautiful intelligent high order predators like when I've swam with hammer heads however they were like big dumb cows thrashing about with their mouth open to take anything that stayed in its path.

 

I certainly haven't been diving in the past few years and honestly when we had a rope around one of the props on the boat last I wasn't the first one to volunteer to dive under the boat to cut the rope away.

im not overly convinced we are in a shark population explosion - more likely to believe they are coming closer to the beaches looking for food as humans have plundered their natural feeding grounds out to sea raping them of food.... humans have destroyed the natural food chain to an extent where GWS's are now coming closer to the beaches to get a feed....

 

i call this our own fault :)

I think we have a population spike + a decrease in feeding grounds.

Den, I consider you to be a very smart individual and have had some interesting convos over the years on this forum and in person, but this would have to be the most ridiculous thing Ive heard you say.
Everything has a place on Earth, without GWS and other Apex preds you would start to see an increase in other species.

Don't forget that GWS also take out the weak, injured, and dumb animals so without them other species would eventually be worse off as these animals that are targeted by the GWS are still in the gene pool.

we need a land predator to do this to humans :)  theres a lot of dumb humans about that shouldn't procreate :)

Can shark shields be boosted up if they were made fixed to cover a far greater area ? I'm ignorant on the technical aspects but could you have bouys producing energy to feed the shark shields ? Whales and seals have increased haven't they as far as their food source goes they seem to love those whale carcasses .Be nice to see more killer whales around .

It would be interesting to see the long term effects of shark sheild exposure.  I've seen birds nesting on air driven bird scare guns at the airport I used to fly from back east.  Perhaps the sharks will get used to the noxious input and it will be in effective.

Well we should encourage the scientists working on growing a wooly mammoth from bone marrow ... to try and resurrect a megladon that will fix the great white problem

I'd be interested in hearing fisheries give us a figure for a desired population size for genetic diversity and other concerns once we have reached said population possibly let licensed fishermen catch excess with trophy type hunters ( if willing to pay big bucks ) putting that money back into other management tools . Yes statistically shark deaths are logically very few but this is about phobias decidedly illogical .Then again Mick Fanning may disagree .

After many years of reflection after this debate, Ive realised with all those beautiful surfers, divers, swimmers, maimed and killed, culling great whites is not the answer, they should be made extinct and salt water crocs too.
