Catch, Bleed if need to . Put in Esky with Ice, Clean Gut & fillet at boat ramp cleaning station( It's against to fillet or cut heads your Fish off at sea , I think, not 100% , I never do! ) . Take home give it final clean before cooking or freezing. don't forget what you bye at the fish market can be up to a week since being caught by the time you have on the Table. Also they sell by the weight so the whole fish with head and all ads to the weight.
