A big crayfish is a thrill to catch, it's unlike a fish, it can bite back! There's many methods but probably the most usual way people catch them is with hoop nets. They're baited with some smelly sort of material - fish heads or rabbit carcass - if I haven't got those sort of things what I do in [the] short-term is use liver - so it could be lambs' fry, or ox-liver or something like that - and you tie it into the middle of the net and Old Mr Crayfish comes along, and if they're there you'll probably catch one within 10 to 15 minutes and you pull the net up and he's in the net.
If we sort of think about the Goulburn River, we've got Murray crayfish which is the second biggest freshwater crayfish in the world and they can grow to in excess of 3 kilos. The biggest ones are actually in Tasmania - Astacopsis gouldi - and they grow to 4, 5, 6 kilos - in fact there's reports of them, in the old scale, of 14 pound. And that's massive - they're almost a metre long. So, in Victoria they don't get to that size but they are still very big.
