harro 1,
Drumlining is used ,along with netting, by shark contractors to kill sharks off our most popular swimming beaches (at least in QLD).
Been going on as long as I can remember.
It's basically just a float or drum with a heavy baited hook,line and trace attached.
This is then attached to an anchor and bobs your uncle.Once hooked a shark will eventually tire and has no chance of escape.
I didnt get into the nitty gritty with ole mate at the ramp so i dont know if he would have attached his drum to an anchor or just by a line to his boat.
He did seem really into it though.....
BTW As much as they annoy me when they munch on a good hooked fish or snip off a few $3 rigs I have to agree with the guys who just accept that we are invading their habitat and so realize that they have their place.
snelly, I only have so much time when I'm out fishing I'd prefer it to be productively spent rather than hooked up to a bloody great shark for hours.
