A lot of times we'll go ahead and clean our dolphin, wahoo or tuna on the cockpit deck as soon as they stop kicking in the box. (Only in places where this practice is allowed by law of course!) When doing this, you'll inevitably get a bunch of blood and gore on the deck. Instead, I've started using a disposable pet pad to collect the majority of the mess. These pads were designed to allow you to keep your animals indoors, so they have an absorbent cloth on one side and a waterproof liner on the other.
You can use the pads anywhere, even in the kitchen if you choose to bring your fish home before processing. The pads make cleaning up almost effortless, and they won't leak through to your wife's fancy tablecloth.
