Some time back we put some small prawns in our pond. Those that survived the cat fish did well. Law of Natural Selection seems to be doing its stuff in our pond. We caught a few the other day and one of the kids seemed very interested in it all.
However to catch the small ones is it seems quite simple. First buy your trap from the local market. People use bait and a net trap. The bait attracts the prawns into the trap. Once in, there is no way out for the little fellers, unless 'helped'. But help I mean of the human kind which means they are on their way to becoming part of a meal!
So here is a quick video of us catching some prawns and 'helping' them from the trap to the plate.
