Shark Attack Prevention
Created this new thread to hopefully induce some constructive advice regarding the topic of the moment...it's not about saving or killing the sharks so don't go there.. theres enough of that already...it's about ideas to maybe help resolve or alleviate the problem...
1) Preventative measures that could be taken by beachgoers surfers divers yakkers when going in the water...eg time of day , particular months , shark shield info , is there ways of determining if sharks may be around etc...what are the ways to reduce the risks when the water..
2) The bigger picture... is there a good way of keeping the sharks away or knowing when the sharks are in close...eg is it tagging sat tracking...nets...one big mother shark shield...should we pen a few up in a large area and do an intensive study...more flybys

cool thread
these are opinions and I'm sure others have varying opinions
1) If people are concerned about sharks attacking them then they should stay out of the water when they feed - dusk, dawn, night, overcast.
Shark shields work against small lemon sharks in a controlled environment. I seriously doubt they'll have an impact on a great white. However, some pro divers swear by them and if it gives you peace of mind then so be it.
Time of year - great whites are known to follow the whale migration.
2) You have to remember that you're in their ecosystem and you're smaller than them and so you may be eaten. Bearing in mind that more people die from falling coconuts or beestings in the world. On average it's one shark fatality a year in Australia and yes we're having a bad year.
Netting has been proven to not deter attacks over east. Around 60% of attacks occur on netted beaches. And the impact of netting on other species should also be a deterrent to using them.
If people are that concerned - go to the pool.
There is already some tracking of great whites but I don't think it is in great numbers.
Fishin for a feed and fun.

I'm intrigued... I know
I'm intrigued... I know there is technology whereby sharks are tagged and then their movements monitored and plotted. I think this has shown that some have travelled from as far as the African east coast to our shores. Can anyone advise:
1) who conducts that research, is it a south african initiative or australian? and
2) why can't we have waypoints set so that when any of these tagged fish come within a certain distance, warnings can be issued.
I know this relies upon the shark coming to the surface every so often to get a fix...
Great thread topic!

G'day Randall
the research is being conducted by the Dept of Fisheries here in Oz. With 20 acoustic stations from Ocean Reef to Garden Island and out to Rotto. They had tagged around 70 great white sharks, not sure how many now. It's a 2 year project and cost $400K. Some of the sharks travel far (South Africa) but some hang around Perth beaches.

thanks. without wanting to
thanks. without wanting to change the theme of these thread I would just like to say that to me, that makes the rogue shark theory less plausible. if they have tagged 70 sharks and they're not identifying any tagged sharks as those responsible for the attacks, then it is less likley to be a resident or returning shark / s???

Also, what research has been conducted into attack / sighting dates. I have a theory that is not supported through any personal research that these attacks generally co-incide with the whale migrations???
Is this a time of the year that people just need to accept the risk is higher at this time of the year?

bouy of cottesloe beach
I have it in my head that fisheries set up a monitoring bouy of cottesloe beach that detects when a tagged GW comes within a certain distance an alarm is sent to a satellite which then relays the signal to Canada which then sends the signal to canberra which then on sends it to Perth. And all this is in near real time at least that was how the article described it. Was this the bouy that the poor unfortunate fellow was swiming to when he was taken recently at cottesloe?
The big limiting thing about this system of course is that first you have to tag a lot of GWs and hope that it is a tagged GW that comes into a detection zone and not a johnny come latly GW. If fisheries could demonstrate through collected date from this system when there is a strong presence of GWs along the coast sensible swimmers could see by the published data that at certain times of the year a greater degree of care is needed when going swimming. We (fishermen/women) know in our own minds that when the humpback whales migrate along the west coast sightings of GWs increase as these things do what they have done for thousands of years they follow the whales and wait for the sick/dieing injured whales and strike at an easy victim. Presumably seals fish and just about anything else that crosses their path will get eaten if the GW is hungry or mouthed (bitten) out of curiosity.
When it can be shown by statistics that at certain times of the year GWs are likely to be found of opur beaches then you are most unwise to venture far from shore at that time of the year as you are putting yourself at a greaterr level of risk in encountering a GW.
I believe that the state government should increase it's funding to fisheries tagging programe in order that a greater knowledge of GW's movements may be obtained, then put this data out in the public domain, it does the general public no good at all for the data to be kept locked up and available to a select few who will/may/could then decide what they will let the public know and when they will let us know.
Fore armed is fore warned if it is proved that shark numbers (GW's) are around in greater numbers at certain times of the year and time of day and people still chose to not take care then there is not much more you can do

Tagging Great Whites
Tagging information and types.
http://www.shark-tracker.com/en/Tagging/Information/index.php
Tagging of Pacific Pelagics - the white shark bit is a bit bogus but there is some interesting info.
http://topp.org/species/white_shark
Info on a WA tagging program from 2005
http://www.aqwa.com.au/foundation/updates.asp
New tagging program in operation - where the bloody hell are you? March 26, 2011 6:00PM
Department of Fisheries officers have installed 20 state-of-the-art acoustic stations from Ocean Reef to Garden Island and out to Rottnest Island to monitor the movements of tagged great white sharks off metropolitan beaches.
Data from the $400,000 world-first system is still being collected, but department chief executive Stuart Smith told The Sunday Times some of the predators were lingering off Perth's most popular beaches for months at a time.
"It's producing some interesting results. We're seeing some sharks travelling huge distances but some sharks staying in a relatively small area for extended periods," Mr Smith said.
Fisheries Department research scientist and shark expert Rory McAuley said the two-year project could reveal new information about the elusive animals.
Surf lifesavers will also be warned if a tagged shark is detected close to Perth's swimming beaches.
So far, more than 70 great whites have been fitted with tiny transmitters. The acoustic receivers record when a tagged shark passes nearby, relaying the data in almost real time via satellite.
There is no data available on the number of great white sharks, but Mr Smith echoed comments from professional WA fishermen who said numbers of white pointers appeared to be rising.

Not sure if the tags
would be cost effective as they are expensive, you would need a lot of them, and they are likely to have a limited life - battery and dislodging.
And not every shark would be tagged.

I spoke to a guy a few weeks
I spoke to a guy a few weeks ago who had a great white stalk him and his wife while diving off Dunsborough a month ago.
The shark rushed them as they got near the boat, but stopped like it "hit a brick wall", shook its head from side to side repeatedly, and moved away.
The chap was wearing a Shark Shield and he is adamant that is what saved them.
As soon as they were out of the water, the shark was back at the transom and bumping against the boat.
I too had wondered if a SS would deter a shark in full attack mode, well maybe it does.

Don't forget the girl with the dolphins at Garden island survived and credits the shark sheild for saving her life,,the others never had one and are now dead.
The bigger the shark the better it works the makers claim .
If we get a few more attacks the government might make them complusory for certain high risk activitys (doubt they will but who knows with the government)

On Edit> I see biggerfish says the same thing just after i posted,i never saw where she got a couple shocks before,,i guess the lesson is turn your shark sheild on it works better that way,lol

Shark Attack Prevention reply
@Wahoo - '1) If people are concerned about sharks attacking them then they should stay out of the water when they feed - dusk, dawn, night, overcast.'
I read the other day statistically mid afternoon was the most prevalent time of day for shark attack, so you may as well be wary at all times.
@Scottywiper - The story you relate is very similar to a testimonial on the Shark Shield Freedom 7 from 2009 'Do they work you say, well I should say YES with a big smile on my face as I borrowed a FREEDOM7 Shark Shield and went shooting fish at Cosy Corner near Albany Western Australia, only to be told later by my buddy, that half way through the dive and in the midst off stuffing a big “Queenie” in the catch bag, that a big white and grey shark had streaked down toward me, “It got to within 5-6 metres of you, then gave an immense shiver, veered then departed as quickly as it came”. he said. (More about the White Pointer later.)'
http://www.digitalreviews.net/reviews/miscellaneous/shark-shield-freedom7-and-surf-reviewed.html
Sounds slightly positive, In 60 dives in 9 months over the last year I never saw any sharks aside from wobbies under of the protection of a shark shield, but I believe my own dives to be far to small a sample to be of consequence and without blood, fish or shellfish to tempt fate.
Tagging will only be successful if it is a worldwide program with information sharing and open reporting for pretty much the same reason culling would not be successful against a migratory population.
What we need is a specialised study group ala Shark Men with an equipped research vessel but in all honesty would they come here or to S. Aus Neptune Islands where the white shark is renowned. Over here sure you get them but are they really as prevalent as there or S.Africa?
How bad is the west coast of S.Africa + S.America in relavent latitudes for white shark attack history? Is it a flow on from the high temps of the leeuwin current last year?

"How bad is the west coast of S.Africa + S.America in relavent latitudes for white shark attack history? Is it a flow on from the high temps of the leeuwin current last year?"
East Coast of South Africa, with the warm currents of the Benguela. This is where the GW is active, from as far as Durban all the way down to Cape Town. On the West coast of South Africa you have the cold Atlantic current, but GW has been spotted as far as Namibia.
Number of attacks vary from year to year. Not that different to AU. What has been an ingenius plan is the Project called "Great White Spotters". We utilize the height of the mountains along our east coast and deploy spotters that form a extensive network that communicates within minutes of a sighting. Various types coloured flags are then rised at all popular beaches and this has been quite affective. The spotters sit high up on the cliffs and use binoculars to spot the GW. You see them a mile away on a clear day. On a windy day, you're f@#@$!!!!!!!
Having said that - this has saved quite a few lives over the past 4 -5 years.
Every day at the Beach is a Good day!

shark shields.. lol...hilarious
we quickly forget that the last commercial diver (last year) in SA attacked was actually wearing two shark shield (one on the buoy and one on him).
He was commercial diving for abalone in some extremely remote water off SA
the poor diver off rotto was spearing (where and what we'll never know).. and was extremely unlucky
At the end of the day.. or each weekend... there are thousands of recreational and professionals users in our waters- locally and nationally.
Shark attacks are terrible, tragic and unfortunate - but are still rare
Shark shields are flat out banned on my boat. I guarantee you will see more sharks whilst you are wearing them scuba diving.

Spearing????
Not sure where you got your information re the Saturday attack victim being spearing anything... His friend that was on the boat with him said the victim put his gear on, and only went down to retrieve their anchor chain that had wrapped around a rock...
Nothing mentioned about trying to spear the rock out of the chain... or even that he took a spear of any kind with him...
Are you even a diver?

If you read it, it says it
If you read it, it says it was a shark pod, not a shark shield, it was incorrectly attached, and that it unlikely to have been on while the shark was getting fired up.
But don't let the details get in the way of a good bagging!
3.13. Senior Sergeant McDonald also explained that once Mr Buckland reached the surface, the electrode attached to the airhose would have been ineffective since it was no longer fully submerged. Ms Wescombe-Down agreed, although she stated that it might still have been partially effective since the underside of the electrode would still have been in the water and so might have sent out a smaller electronic pulse (T49).
3.14. This, combined with the fact that the airhose may have bent while on the surface, thereby reducing the gap between the two electrodes and rendering the device even less effective, may have combined to rob Mr Buckland of the protection it might have otherwise provided.
4. Conclusions
4.1. Taking the above evidence into account, I form the following conclusions:
· That Mr Buckland was wearing his ‘Shark Pod’ device incorrectly at the time of the attack on 30 April 2002 in that the fin electrode, instead of being attached to his fin, was attached to his airline supported by a float which had the potential, particularly when he reached the surface, to make the shark repellent device less effective;
· The practice, adopted by Mr Buckland and Mr Jenzen, of turning the ‘Shark Pod’ device off when they reached the sea bed and commenced working, also reduced the potential effectiveness of the device in that it failed to repel the shark during its initial investigation of their presence.
Oh and:
5.2. Taking into accounts Senior Sergeant McDonald’s comments, together with the ‘testimonials’ from divers who use the equipment (including one from Mr David Buckland, a brother of the deceased), it seems clear that this equipment can be effective in repelling sharks in a significant proportion of circumstances. Of course, having regard to the unpredictability of these creatures, it cannot be said with certainty that the device will always be effective in any circumstances. It seems to me, however, that both commercial and recreational divers who dive in areas where they may encounter sharks should be encouraged to wear this equipment. Ms Wescombe-Down used an analogy with seatbelts and airbags in motor vehicles, saying that although they will not guarantee that the passenger will survive every crash, the chances of survival are enhanced. I agree that the same applies to these devices.
5.3. I therefore recommend, pursuant to Section 25(2) of the Coroners Act, that commercial and recreational divers, when operating in waters where there is a risk of the presence of sharks, should wear a shark repellent device of the ‘Shark Pod’ or ‘Shark Shield’ type, provided that the equipment should be used in accordance with the manufacturers instructions, and should be turned on for the entire duration of time in the water.

Yep, I read all of that too
Yep, I read all of that too and totally agree - the Pod was rendered ineffective by
1. not being fitted correctly, and would have basically been useless when he was on the surface.
2. high probability that it was switched off when the shark was checking him out.

Who cares if one was reported two weeks before, anecdotal evidence (I sound like Colin Barnett) says there were plenty around at the time, but 125 is the number they have tagged.

how bout u all get in the water w a shield on a see what happens when a 5 meter white comes at u at flat chat if it works u live if it doesnt you die that should sort the debate out! remember it is the ocean we are out of our comfort zone in this environment! you know the danger when you even think of going in the water you just choose to either ignore it or just think that its not gona happen to me! what about the whale that was buried at cottesloe in the late 70s and not long ago! do you think that the oil fm the carcass might just be seeping out of the sand and will continue. just a thought

Have you even read the above posts?
This is a topic on how to prevent shark attack, not the kill or let live debate in the other thread. The people who have commented in this post are talking about the effectiveness of the shark shield/shark pod devices as they are pretty much the only in water non barrier defence. Did you not see the link with the video of the great whites during shark shield testing of neptune islands S.Australia, and woah and behold, it turned away a 16ft white! I am not naive enough to think that this one off instance is to be the saviour of us all, but tis a start.
The people in this topic are well aware that the ocean is not our natural environment, but are trying to reduce the risk.
Ill go out on a limb here and say that we are all aware of the rumours of whales buried at cottesloe, just a thought, but what the fuck am I to do about something that happened 40 years ago?
Thanks for the valuable contribution to the topic at hand.

dont think ive heard of an attack where sum1 was wearing a shark sheild (correct me if im wrong please..)
tagging.. woopi doo all they doo is close the beach if its spotted.. give it 20 minutes its at another beach that isnt closed
go to the pool if u dont want to take the risk.. if sum1 jumped my backyard id probly eat em too..

Shark shield
Did a cage dive with pointers a few years ago, calypso star port Lincoln south aus, skipper said they had done extensive testing with them and were 100% confident they worked well, as for shocks well it's a small kick, doesn't hurt bad, just an occasional small annoyance.

As fisherman I believe there
As fisherman I believe there is something we can do to help with the safety of the public and that is to be considerate of where we clean fish and dump the offal. The reason for my statement is as follows: -
Two years ago, I was down the beach at Busselton about an hour before sunset. A visiting fishing club had a competion that day and had headed to the beach to clean their catch. The water close in was littered with offal, fish frames etc. I was amazed to watch 2 * 8 to 9 foot bronzies come into the beach and start to feed. I was even more amazed to watch these sharks nearly beach themselves in their feeding frenzy.
Now this particular fishing club stays in the same caravan park twice a year for fishing competitions. Due to the caravan park not allowing fish cleaning in the park, I assume it is common practice for the club to clean on the beach after their weigh in. Surely as fisherman they should realise it is not a good public relations exercise to burly up such public swimming area's.

pro shark /fish netting boats
i read this thread the other day and seen many interesting points and had 2 add this after i just heard through a facebook thread about the pro boat working out from gracetown (margaret river area) and their practice of cleaning their catch at sea and dumping offal not far out behind south point a popular surf swim dive beach where a fatal attack happened not long back im not sure about how legit these storys are but if so is this legal for them 2 do ? seems irrisponsable 2 me if they are as i have heard they proccess around 300 fish/shark a day (mind u this is happening now in the ban when us rec fishers are being blamed by them for fish depeltion ok thats a whole other can of worms ) now that's alot of berley if you ask me ,could this be one of the reasons for more sightings in the gracetown bay area ? just thought i would throw it out there ,maybe some one better informed than me out there could shed some light on the subject ??
cheers barry ! ps ill still be surfing but looking over my shoulder more often thats for sure !

Cleaning catch
Very much doubt if they are deliberately dumping the offal in one spot each day.
We used to clean fish as we pulled gear or if there was too much coming in wait untill we had finished and were travelling to another spot to reset the gear then finish cleaning while returning to Canal rocks, Kilkarnup, Hamelin , Dead Finish or back in to the bay at Quindalup. The offal would be dumped as soon as it came out of the shark /fish not saved up and dumped in a big heap [lots more work that way]
After each set we would move probably 3-5nm at least before resetting so as not to deplete an area.
As an amateur at Gnaraloo we would come in to the bay and hang off the mooring and while cleaning the catch [making ourselve available to fisheries if they wanted to check us] then take all the offal back out as far as to be able to see the "Billy Goat "track before dumping it. This was well before the place got to be as popular as it is today, but we always saw tigers and whalers in the shallows regardless.
