I usually wait till just before heading in to bleed my fish. As you never know, when your working for that last fish, you get a triple and the guy reeling one in has his fish of a life time on. Toss back another fish that is still lively as quite often 2 of those 3 will be nice ones. I usually club them, slit em and throw them back into the livewell and let them bleed out. Then once back at the ramp, into a cooler. During the hot summer, I'll club them, bleed them right away. Give them a few minutes, then into the cooler.
