Some fair comments there....but going back to loosing pots, it s only the odd few that get lost. Unless the string has been towed away from its position by a large tanker (the rope will snap before it goes too far), or if the lost pots have rolled into a big ball, they are relatively easy to find, a good skipper will know where to look for his pots if they were at risk of being towed away in the tide/heavy seas....
But many that are lost are due to skippers being shot down by other gear and just ruthlessly cutting off the other boats pots and sending them to the bottom never to be seen again....i have seen it happen many times!
So SOME only have themselves to blame if lost pots damage the stocks....but it doesn't take long for an un-maintenanced pot to be smashed to bits by tide and weather!
