My brother just shot a striped marlin spearfishing in NZ. This is quite an accomplishment and puts him in an elite group of people. Basically, they troll teasers around while the spearo (freediver) is all togged up at the back of the boat ready to go. When a marlin is seen behind the boat the diver rolls over and as the lures and fish shoot past takes the shot. I'm stoked for him!
