Dolphin killed at Mettams

This thread was going soo well, good discussion by people with opposite views showing respect to each other. I, like others don't agree with what some say but it was refreshing to here people give good clear reasons for there opinions, not just a slanging match.

I hope smicko is right and it's just a rogue that has hopefully left our shores but I'm not holding my breath.

1) no, I am not high - why do you say that?
2) the internet never lies
3) without you expressly admitting it, I think by your reply there was an implied concession by you that hunting with an arrow is inhumane and inconsistent with a stance against culling sharks - just be a man and admit it next time
4) so if you are against hunting where animals are endanged, does this mean it is ok to hunt animals (whether teristrial or marine) if they are not endangered? If so, if it was the case GW weren't endangered, but that they killed endangered species, then it is ok to hunt them?
5) sorry to get involved, but I don't like trolls who troll for trolling's sake.

I agree, I dont think its a rouge either tbh. I think that we just have more than normal at the moment.

In saying that sightings are off the charts at the moment but the thing is we really are looking for them now more than we ever have before!

I have posted the following before and its my opinion so feel free to shoot holes in it
--------------------------------------------------------------------------

There are a few reasons that sharks are more prevalent around WA these days and a lack of food isn't one of them.

I think the first thing to look at is whales and their migration past Perth from the north west to the south west. Back in the day when we used to hunt whales, the whales would stay miles off the coast to try and get past the whalers with out getting hunted.
As of 1978 we stopped hunting whales and their numbers grew and they started to get closer and closer to the coast. To the point that I have seen them 100m off shore last year, something that I have never seen before at local beaches (Perth).

The second thing is that we haven't hunted Great White Sharks for the last ten years adding to their numbers by more than we know. With more whales means more sharks as the sharks hang with whale pods for an easy feed, so with whales coming closer so are the sharks.

I may be wrong but this winter has been the coldest as far as water temp in a while and we all know that GWS like colder water, and yes they are found in warmer waters but they prefer colder water.

Also seal populations have gotten larger so food for the GWS isn't a problem, and over fishing imo isn't the problem at all.

The rogue shark theory is not really an option as the sheer number of sharks spotted tells us this cant be fact. If you don't hunt them they will come and in numbers. The tagged sharks prove this beyond all doubt so this theory can be put to bed.

The answer? Well tbh there isn't one that we can throw out there and fix the problem tomorrow, and I don't think that there will be one in the near future that is sustainable.
Part of the solution is to try and stop it before it happens and more tech thrown at shark shield type devices the better and these are not a solution but a piece of mind but they will have to work much better than they do now.

As far as culling them goes killing ten even twenty of them might help for a while but for how long? A month, maybe two? Some of these sharks come from as far away as South Africa so culling unless you were to kill twenty a month isn't going to work and is not sustainable.

A lot of people believe its just one or 2 sharks causing the majority of the problems & my thoughts are they're probably right. Although I've never heard that opinion explained as well as smicko has or with the added theories of travelling around encountering little to eat other than bony seals between busso & the midwest...If it is the case, I hope they or it has buggered off to greener pastures with tastier less bony seals too... Earlier in the year I commented to one of the stories after the bloke at Bunker bay was killed...where I wrote it would be a good idea to allow fishing for great whites within 5km inshore between busso & Yanchep for whites 3m & over. This way we would be reducing the number of large sharks & in turn reduce the number of shark attacks.

(My turn to be inconsistent as this is a troll for trolling's sake ...)

So if GWS or GRS (if we are talking about the rouge variety), eat whales and dolphins, and whales are endangered and dolphins are cuddly, does that not mean we can hunt sharks?

Who's trolling now Trev?

I'll give you that one. Well played

It would be interesting though and I pray hope so, to see if this and for the next few years we don't have any fatalities let alone shark attacks. It would be intriguing then to imagine what the public reaction would be and expert reasonings after...

Here is a link to the kind of thing i was talking about.

Seems to be cheaper and as for not proven, well the QLD overnmnet is doing the same thing but using it to combat fire Ants

Not really, read the posts back again.
Rbl gave his opinion, and as usual Suba gave one of his head up his own arse responses.

Yeah I would have thought this is the sort of thing that could be done with a UAV or the like very effectively and at a fraction of the cost, it's pretty amazing what can be done with even a few thousand dollars with these things, I would have thought that half the budget of the current aircraft and helicopter program would have got spectacular results (nowhere near as visible to the public though).

That said, I've been in or around the ocean most of my life and acknowledge the risk in relation to sharks, what gets up my nose is the constant stream of "beach closed", "shark sighted" dribble that's in the media. I for one liked the days when I could acknowledge the risk, still get in the water and not have the "where's the shark today" thought running through my head. I'm sure that's been said before and there are probably a few thinking it also but had to have my turn at saying it.

2c

you're a cunny funt suba.

The sad thing is RBL, I doubt you mixed those letters up on purpose....

I think if the alarm goes off, and the waves are cranking, then you're a lucky bugger. You just might get good waves without the severe crowds. The past few days have been a prime example.

They close the beaches for a Tiger Shark, yet in most parts of the world divers go looking for Tiger Sharks to swim with.

Google scholar is great, but it's hardly a drop in the ocean with what it gives you access too. Most of the peer reviewed papers require authorized (expensive) access to view them.

There are so many papers on shark research out there that are not available through google scholar. Personally I wish peer reviewed journal papers were free for all to view, but sadly, they aren't.

Sometimes you can get copies of journal papers just by googling the title, but google scholar certainly doesn't give you access to a whole lot. But it's an awesome concept.
