Placment of seine and haul ropes. The trap-seine method of partial harvested usually cannot be used more often than once every 7 to 10 days, because fish become wary of the trap.

As the seine is drawn across the pond bottom, the mud line stays on top of the mud, eliminating the digging effect of lead-weighted lines.
