maybe just try throwing some water in the cooler and cutting them as soon as you catch them then throw them in the cooler. yea you will have a bunch of red water in the cooler but your cooler will also be nice and clean. then when you get done fishing dump the water and put them on ice. might be more hassle than its worth just seems easier than carrying all that extra stuff like bucket or stringer things like this, I mean you are already taking a cooler. just a thought, I've used buckets, the big cable stringers and live wells, each works just fine, but there are days its hard enough to get them eyes in the boat the last thing I wanna do is hang them over the side of the boat lol...
