And why do scientists and studies and stats have any credibility? You look at the contrasting opinions on global warming from highly qualified and reputable scientists! And so why should a scientist, an expert in marine biology, command respect and credibility? Just because he calls himself a scientist? What is relevant, is his agenda. Not his qualifications. It's pretty rare you get a study or scientists opinion that is without subjectivity and bias. In regards to the great white population, I would give more credence to a surfer, or fisherman or diver than some fat bloke in a lab coat with a calculator.


And there is the problem. Its like Monty Python all over. She's a witch She's a witch Says the hordes of INTELGENT folk.

I give up.[}:)]

As for Baksey and Woody how can you say fishing and fish stocks are not in massive decline I have people tell me all the time fisheries is better than ever, and in the next breathe complain about having to travel to Green head to catch fish[}:)]



They must be hacks with no idea of how, where or when to fish.
Plenty of awesome fishing to be had right on perth's doorstep.

I'm sorry Woodo, but there is absolutely no credible argument to be made against the claim that fish stocks world wide are on a the massive decline. Every year we set the bar lower. There may be pockets where you can still get a good feed, but it's nothing like it use to be or should be.

Interesting email just read out on "old farts n redneck radio 6pr"

An experienced fisherman has supplied a photo of the second last White Pointer shark caught off the coast of WA before the species was protected by law. Geoff made the observations based on his experience in an email to Paul Murray that you can read below.

Hi Paul,

Just writing to you on these shark attacks, I use to work on a cray boat and it was part of my work on that boat.
We caught the second last white pointer before they made them a protected species.
Just wondering if you could do the facts and figures on when these shark attacts are made and what brings them in close to these areas away from seal colonies.
My thoughts and knowledge is , it seems to happen around the time of crayfishing industry have all their pots in close to the beach areas.
The pots are not pulled as often and are left in close depths with full bait, because of fishermen waiting for the price to go up so they get the most out of the fishing quota that is in place
Also crayfishing is all year round and not the old system of seasonal.
It seems these shark attacks in the last year around the southwest are when the cray fishermen bring their pots back in close from the deep, also since this new system of all year crayfishing. Pots are in the shallow areas more now
The Seals love playing around cray pots as it is a easy way of getting a feed of cray fish, they scare the crayfish to the escape hatches and the size crayfish get stuck in the escape hatch leaving the tail of the crayfish ready for picking by the seals.

The White pointer is a very intelligent animal and cruise these smelly pots as they know seals will be there out in the open looking for this pots, they surface after taking crayfish from one pot then while on the surface look for the floats of the line and head for it and then surface again checking where the line of pots are.

So look at the times of when the shark attacks happen around Perth areas/ south west, its mainly when these pots are in close to the areas.
Also these shark attack tours when they put people in a cage and bait white pointers to come close to the cage for a experience of a life time.
teasing a White pointer is not a good thing and if these tour operators who do this, they should be the ones to tag a white pointer and you will find it will be one or more of these sharks that is taking humans as part of their kill now as they are use to the shape of humans and not seals.

The answer to this problems is just have only a selected people boat in areas to cull the sharks in close, the one in the attachment was the second last White pointer before making protected species , this one was caught out in deep water over the edge off Leeman.
Change the crayfishing back to only the old system, with still the quota.

But Norman moore not sure as you have stated to your friends you have no knowledge on the fishing industry only of what you have learnt of just a few friends you know in that industry and have made the changes to it ,not on all of the industry.

It does not matter if you change it so we start culling these White Pointers again, will you get the ones that are human killers.

Stop these cage shark tours or get them to tag them so you can then study that they are the ones killing humans.

I'm just wondering how they can count em to say they are endangered!!!

Never said fishstocks weren't on the decline suba. I know they are. Just saying you don't have to travel to far to still catch a decent fish or get your already reduced limit of demersals. I know fishings not the same as it use to be but hey what is these days? I remember the surf use to always be better years ago...
But there is no way in the world IMO any of these spate of attacks has something to do with lack of food source for whites.

Sharks hunt to eat. If they are starting to eat Humans (like they seem to be doing) than its a fairly obvious link wouldn't you think

Nah I don't think it's an obvious link at all.
It's your opinion which is fine. Everyone has and is entitled to one.

There are so many people chiming in with opinions formed on emotion and misinformation. Fingers are getting pointed at everything from commercial fisherman to cage diving operators, and even some muppet on here has tried linking shark attacks to Chernobyl.

5 fatal attacks in 10 months are the only numbers anyone needs to know. What more evidence to people need to realise action is needed. Now.

I don't mind being a muppet. It shows I have done my research By the way LS, how's that longboard repair going? Not going to read through everything but I will cut to my point and that is we need to have the bigger picture in mind. Culling is not going to help anything in the long run. If you want to put some measure in place make it so that we preserve rather than destroy.

I pointed out Chernobyl because we know the damage it had on the environment and guess who was the cause. Yet leave it untouched for decades and nature has brought it back to life. The natural ecosystem exists on a delicate balance. F*** one part up and you are sure to feel it's effects. Shark attacks are only a precursor of the bigger picture and people need to realise that what they do now will have a direct effect on the future. Fish stocks need to be replenished, shark tourism banned and greater research into how humans effect the world and what leads to incidents such as increases in shark attacks.

At the end of the day, I know all the nay - sayers are going to blast me and red thumb everything. Take a look at the thread on G.D. regarding the carbon tax - so my only message is simple:

Stay OUT of the water. It is not essential for life. If not accept the dangers involved. I'm going for a surf now so I wish everyone perfect waves and no fins of the sharky kind.

For someone who hasn't surfed for long you sure have a lot of strong opinions new guy....maybe it's coz you know no different and expect a shark fest every time you surf?
After having surfed for over 20 years there has been a definite change on the water in regards sharks. I like the old days.
