But doesn't it count as fishing in a way? Here you can fish with only size and seasonal restrictions but I know interstate you need a permit to fish (Not all states)
Things like Mud Crabs and stuff you eat have various restrictions, look up fishing regulations if you want details. The smaller types require a licence to collect commercially I think. Im pretty sure you can catch them for personal use without any permit, just no dealing :lol:
There is a guy called Bob, he collects freshwater "everything" and he comes across some nice crabs. You can contact him on 07 40320477 Cairns Ultimate Aquariums.
I got most of these from him. He is happy to lend them to me for a shoot but otherwise he sells them.
The one in the 4th photo is from Iron Range and the last one is the Blue crab from Christmas Island.
