As another day goes by where a whale carcass remains on the shoreline south of City Beach, authorities are taking the opportunity to tag the sharks lured by the remains.

authorities → go → remains
But shark experts aren’t convinced the predators will take the bait.

predators → convince → bait
A 13-metre whale was spotted beached at 7.30am on Monday morning and quickly attracted a number of great white sharks into the shallows of the beach, some more than five metres long.
asserted
whale → spot → beach
The carcass was reported by Surf Life Saving WA and the organisation’s helicopter reported a number of sharks had begun hanging around the coastline near Swanbourne, just south of City Beach, around 10.30am.
asserted
number → report → 10.30am
The helicopter reported seeing three, four-metre long great white sharks circling about 15 metres from the shore, about 2.45pm.
asserted
sharks → report → shore
A small hammerhead was also spotted heading south from Trigg Beach, towards the carcass, and two tiger sharks were reported further south at Cottesloe Beach.
asserted
sharks → spot → Beach
The carcass was originally planned to be removed on Tuesday, but the Town of Cambridge has had to push that back by a day as the equipment needed to lift and transport the whale isn’t available until Wednesday.
asserted
equipment → plan → Wednesday
With the beach closed to the public, the Department of Primary Industries and Regional Development has taken the opportunity to drop three drum lines into the ocean in a bid to tag curious sharks.
asserted
Department → close → sharks
Macquarie University Fish Lab spokesman Culum Brown said this behaviour is common for sharks “looking for a free meal”.
asserted
sharks → say → meal
“Sharks just do what sharks do, right?
asserted
sharks → do → what
I mean, if there’s a free meal, they’ll certainly be attracted to it, and it’s very well known that they’re attracted to whale carcasses,” he said.
asserted
he → mean → carcasses
“The sharks will be in feeding mode, and I mean most people probably think of sharks and particularly white sharks as being sort of attack, kill, ambush type predators and that sort of thing.
asserted
people → mean → thing
“But actually, they’re quite happy to have a free meal, and a massive whale carcass like that will keep them going for a very long time.
asserted
carcass → ’re → time
Throughout Monday and again Tuesday morning great white sharks between three and five metres in size were reported swimming 10 and 15 metres from the shore near the carcass.
asserted
sharks → report → carcass
Brown said sharks will go to great lengths to get to their meal, even if it means beaching themselves.
asserted
it → say → themselves
“I’ve seen sharks virtually beach themselves in order to get access to easy food.
asserted
sharks → see → food
When there’s a big school of salmon or whatever in the shallows, the sharks will come right in, no problem at all,” he said.
asserted
he → ’ → shallows
“Once they’re in that feeding mode, they do a sort of a risk reward calculation in their heads, and if there’s a good meal within reach, they’ll do their best to get to it.
asserted
they → ’re → it
“So the depth is not really an issue for them, and it’s unusual because we normally wouldn’t see sharks coming in that shallow because they’re deterred by human activity and that sort of thing.
asserted
they → ’ → thing
“If there’s a free meal like a whale just sitting there tantalising, you can imagine the smell.
asserted
you → ’ → smell
It must be driving them crazy.”
asserted
It → drive → them
It is for this reason he believes the shark tagging efforts might produce little reward.
uncertain
efforts → believe → reward
“It’s an odd decision because quite frankly I think that the attraction to the whale will certainly be way more powerful than any bait they can put on a hook.” he said.
asserted
he → ’ → hook
“So I don’t think that’ll be very successful, but given that the sharks can’t actually access the carcass at the moment, it may be that they’d happily go off and find something in the nearby vicinity as an alternative.
uncertain
they → think → alternative
“But honestly, I think they’ll be pretty determined to get that carcass.”
asserted
they → think → carcass
Fisheries minister Jackie Jarvis said fisheries officers were out on the water to drop the drum lines into the ocean.
asserted
officers → say → ocean
“We make use of opportunistic tagging opportunities, and when there are whale carcasses, we make sure that we use them as an opportunity to tag sharks,” she said.
asserted
she → make → sharks
“We’ll tag as many sharks as we can.
asserted
we → tag → sharks
It’s important to remember when we tag sharks, this isn’t just a tag on the dorsal fin.
asserted
this → ’ → fin
The shark is caught.
asserted
shark → catch → ?
It is actually pulled up alongside the boat.
asserted
It → pull → boat
It is actually turned over, and an internal tag is actually surgically inserted, so each shark actually has sort of minor surgery on it.
asserted
shark → turn → it
As for why the carcass will be removed and taken to a tip as opposed to being dragged back into the ocean, Jarvis said it was based on the weather conditions.
asserted
it → remove → conditions
“With regard to the removal of the carcass, I’m not an expert.
asserted
I → ’m → carcass
My understanding is, however, if the whale carcass is dragged out further in this type of weather conditions, it increases the chance of the carcass breaking up and washing back onto shore, and therefore causing more shark activity,” she said.
asserted
she → drag → activity
Brown said that removal to a tip would be the most logical decision, but that it should be done sooner rather than later as the smell of the carcass could linger for weeks.
uncertain
smell → say → weeks
“The longer it stays there, the more sharks will come in,” he said.
asserted
he → stay → ?
“The smell could last for weeks depending on how long it sits there for.
uncertain
it → last → weeks
Usually, what happens is that the oil and the smell infiltrates into the sand, down into the water table, and as the tides come and go, it spreads out into a broader radius.
asserted
it → happen → radius
“So it could be weeks before that smell is, you know, sufficiently dissipated.
uncertain
you → know → ?
