By far the most effective means of securing birds is to stretch a net
between trees or poles where the birds are accustomed to fly. Wooden
decoys are attached to the net in order to attract the game which, once
enmeshed, is easily caught.
Various devices are employed in the capture of fresh water fish,[16] but
the most common is a torpedo-shaped trap of bamboo (Fig. 19). Stone
conduits lead the water from streams into the open ends of these traps,
thus carrying in fish and shrimps. The funnel-shaped opening has the
sharpened ends set close together so that it is quite impossible for the
prisoners to escape, although the water readily passes between the
bamboo strips.

in salt water fishing.
