There are two boats somewhat similar to the river drift boats in Oregon. They paddle their boats stern to stern. Each has a net aboard, and they join the nets and then take off in opposite directions, laying their nets out as they go. They make a big circle and then spiral in toward the center. Then they start making noise in the water with some kind of plunger; we think to attract the fish. Then they reverse the process, pulling the net in as they go and removing the fish caught up in the net.
Sorry, some of these pictures are out of sequence. I spent the better part of an hour trying to put them in order without much luck. Hopefully you can figure out the order from our description of the process.
