The tangle nets I have seen in the Philippines are not tangles of frayed
ropes but are long, narrow, rather conventional-looking nets that are
lowered to the bottom in deep water and left for a time to allow shells to
get entangled in them.  One of the long sides has weights to keep it on the
bottom and the other is free to sway with the current.
