Like Squire said, I drop traps in more structured areas where the commercial guys sometimes seem to avoid a bit. The prawn opening for sporties usually closes a few days before the commercial opening then will reopen a few days after the commercial opening. I’ve found the commercial guys are just out there trying to make a living. Once I accidentally set on top of a string that they had laid out. My line was cut but retied so never lost any gear, just had to splice my lead line. Ive been ou on a friends commercial prawn boat helping out and anytime we tangled with sporty gear, if we had to cut the line we always retied it.
