nice job on the quick double. i hope the sportie didn't get squat. i hate when they do that.
in my experience, the color of the meet has mostly to do w/ how you handle the fish after it's caught. to get that real nice, light colored hamachi you should bleed out fish right away. i cut artery from gills to heart and try to keep fish's tale above it's head. i also gut fish as soon as convenient. parasites can travel from gut to the meat after the fish dies, so if you are going to eat it raw, gutting is not a bad idea. gutting also helps to get fish colder quicker. i shove ice inside after gutted and mix w/ saltwater for slush. fish is firm enough to filet within a few hours.
