Bass - I clean them when I get home....until then, bury them in the sand if I'm on the beach, otherwise, just try to keep them out of the sun (not that the sun is usually up that high when I fish anyways...
), and then get them on ice in a cooler or trash bag back at the car.
Blues.....I usually gut them in the wash a soon as I can....which may be immediately, or at least within an hour if there happens to be a blitz happening that I don't wanna miss....
But, the "supposed" gaminess that not bleeding either bass or blues may give them doesn't bother me, in fact, I prefer it, but that's just my taste......
