There's a place in southern India I've been to a few times, and there's net-pulling from shore: a little boat made of three logs takes one end of a net out in a big curve and back to the beach. Then some forty or so pull both sides in, with people in the water at the back of the net shouting and slapping the water to drive the fish. There's singing shanty-style (a shantyman one line, the haulers the next line, etc.). I have never had any way of recording the songs, though.
