I wove the main body of the trap from lawyer cane then made the funnel from sticks with vines woven between them. The funnel was then inserted in the top of the basket and was complete.
I humanely killed the prawns using the splitting method which destroys the central nervous system (boiling alive is more painful). Then I put them back in the pot with water. I collected some yams that I planted years ago from wild stock and put them in too.
I took 5 hot rocks from the fire and put them in the pot boiling the contents. The prawns turned red after cooking. They were peeled and eaten. The yams were also peeled and eaten.
This method of catching prawns is easy with the only skill needed being basketry. In practice, a long stretch of creek might have several traps collecting food each day without any effort on the part of the fisherman. Bait is not necessary to catch prawns as they will be naturally be drawn to the fish trap out of curiosity. But scraps from previous prawn may be used to bring in new ones (they are cannibalistic) or other fish like eels. The prawn trap is easy to build and can be reused many times.
