Okay, so let's say WA went ahead with a cull.
How do you determine which ones get killed and which ones live? Do you jduge it on size and kill the large ones which are also the most important for the survival of the species? Or do you just kill the ones we see close to shore? Which poses the problem that all white sharks forage in shore from time to time. Do you wait for another attack and go after that particular shark? what happens then when you cut the shark open and find out it's not the one that committed the attack? Go get another one till you do?
Aside from the fact I think the idea of a cull is ridiculous, I really don't know how they could attempt to do it sustainably. Last time we had a shark cull there was considerably less outside pressure on the species and that has allowed it to very slowly turn around.
EDIT: By the way, I'm not just arguing here for argument's sake. If more and more people become in favour of a shark cull then it's worth discussing how it would be done.
OK I'll go.
First off I am not in favour of a go out to the ocean and just start culling a certain amount of sharks to reach a culling quota or anything like that. That IMO would be stupid.
I would be more in favour of a selective kill.
For example (which i think i have mentioned previously) a couple of weeks ago we had 3 sightings in 3 consecutive weekends, all metro of an approx 4 - 4.5m white.
One sighting by fisherman off southern cardinal marker (off scarb area)
One by a diver whilst diving off Hillary's
One by fisherman off Mindarie.
Too me it would seem like there is a pretty good possibility that it is at least one shark hanging around the same area for whatever reason. Snapper/winter tailor perhaps at this time of year.
I think that shark should have been baited, NOT berleyed for, for a short period after the sightings.
If there was a boat setup ready to go at a metro marina they could be at a spot within an hour of a sighting ready to go. A couple of hours at most! Yes the shark may be long gone by then, BUT it may not.
After an attack if a shark is followed directly and known to be the killer eg. Cott attack, destroy it.
Down south or Wedge Attacks for example bait for the shark directly after which i think they did in the case of the wedge one. Perhaps the more remote areas burley could be used but only with suitable signage,warnings in place to make all ocean users aware what is going on.
Burley in metro waters would definitly be a no no IMO.
I understand there may be bycatch which is unfortunate but there is also a very good possibility that the culprit will still be in the area.
That's a few of my suggestions.
Don't get me wrong. I don't want the whites culled to a point of extinction.
I know we need them in our ecosystem.
I just don't think we need them in the numbers that we have been seeing them of late.
