Cant really see how a golden mile rule could help sharks.
Yes maybe it would work for cod stocks etc,to ban gill netting inside 1 mile,but cant see its relevance to sharks.
Some of the best trout runs are only 200 yards from the beach,so by banning these fisherman,you jeopardise there income.
I fished on a salmon boat for 6 summers and i can safely say ,you have more chance netting a shark in deeper water than in the shallows,no question.
only thing we ever caught in shallow water with the drift net was,trout ,puffer fish and fanny pads.
