The otter boards which herd the fish into the trawl path by dragging up a "sand cloud" that creates a barrier of escape. [9] The sweeps and bridles continue to herd the fish further into the trawl. The wings and ground gear minimize the potential for fish to escape, which also tires the fish and enables them to drop into the body of the net.
