Thread: Koura trap

I am keen to catch a few of these creepy crawlies for a feed and I have a trip next month to a sufficiently remote and unpolluted part of the country where there should be some.

Will one of these work or am I better off with a bundle of fern with a bait in the center? Is the green on the mesh to bright a color? Any other recommendations for getting a feed.

Also what elevation and water temperature do these spiny buggers live in? Wondering if I can get some from arthurs pass. Canterbury is fucked in terms of water quality between the irrigators sucking the water out of the ground and the cow poos in whats left of the rivers.
