Someone's taking the piss here:

"Anecdotal reports from fishermen suggest that sharks are able to recognise individual vessels, meaning these export vessels will result in a concentration of the shark population when the vessels are present as the sharks seek an 'easy' meal."

Does anyone REALLY expect that a shark can 'scope' individual ships & 'remember' it's a live export ship with potentially free meals being thrown overboard?

Anybody found/seen/smelt half eaten sheep carcasses floating on the water in/near Perth?

I used to bunker the sheep ships when I was on the tankers and I've had a good look in them. I spoke to a couple of people on board and asked what they do with the dead sheep. I was told they used to throw them over however it's now law to mince them and then the mince goes over the side.

What I didn't ask was if there is a distance they have to travel before they do so. One would imagine they can't do it heading out the river.

If anything I reckon it would get the noah's following the boat further out to sea.

If this could be considered even vaguely true wouldn't sharks follow the boat offshore for their contiuous meals?

I don't recall sharks being too scared to head off into deeper, 'sharkier' waters and surely there would be a similar level of fatalities where the ships are exported to....Hmmn??

This isnt bollocks believe it or not, last year in the red sea area the was a number of fatalities and attacks, from what i remember about 3 people died a german, a russian, and a brit all holiday makers, and approx 5 attacks non fatal, the local authorities linked it to dead sheep being dumped from a live export ship on route from australia to the middle east.

Yup, I worked out there for years as a diver, was a dive master for a shark migration documentary triggered by local divers spotting zambezi bull sharks in Sharm area. Red Sea wasn't supposed to have zambezi bull sharks... Turned out they followed the sheep boats in from the Gulf of Aden. They don't follow the ships in through the busy and noisy Sues canal so end roaming around Ras Mohammed ans the Straights of Tiran. And yeah we did ocassionally see sheep carcasses floating. Can't remember the name of the shark migration expert (70+ year old Brazilian dude) but he had a theory that the sharks identify the sound or prop vibe of the ships.

spot on dutch, anyone who studies shark behavior will tell you how clever sharks are, ive spent a bit of time on dirk hartog island on and off, and seen some specky ways in which they hunt in packs and choose locations as a food source, the arnt many species that have lived on this planet since day one sharks and crocs have, so they have to be doing something wright

www.gyropatrol.com.au is a new project that can give Aerial Surveillance over Perth beaches and surf spots. It's a non profit project and in the future could deploy flotation devices for swimmers in trouble and Shark electric shock high amp drop buoy's that pulse huge amps into the sea to drive them away, food for thought!

Assuming this is true, it would mean there should actually be less sharks here cause they are following the ships out to sea and staying at the destination.

In relation to the sharks "recognizing" the ships. I would imagine the constant hosing out of the pens aboard the ship would leave nice trail of pretty recognizable stench in the water. Pretty sure they wouldn't bottle that sh$t aboard.
Similar to how seagulls tail fishing trawlers, pretty sure a big shark is a tad more intelligent than your average seagull.

As a vote for the affirmative, I read in the novel 'Papillon' when a prisoner died, they would have 'burial at sea', only just off shore from a rowboat, in a canvas bag. The passage of the book here describes how sharks were keen visitors at each one of these 'burials'. . .

So what you're saying is we need to stop eating lamb so the sharks can't smell it on our breath?

Drop a gybe and fart and the shark is on to you!
