You don't shoot it when it's swimming by. You raise it up to the surface and shot its brain out, then hoist it up. To do otherwise is to put everyone's safety at risk esp on the deck of a crowded boat in a giant washing machine full of lethal cold water. I don't think the jerks who make these rules have a clue about the conditions people fish in up here, even on "good" weather days. I think they're a bunch of upper crust jerks with their own pleasure craft used to having a team of underlings lift their marlin or whatever on board. But I digress ;-) I'm really just burning with petty envy.
