Take a picture of the fish to capture the natural colors o fthe fish , then put the fish in a bag and freeze it guts and all . Then when your ready carry him to a taxid. Have done plenty of them this way. It is best to get a good pic. For the person mounting the fish will have something to look at to match up the color of the fish when he was caught. They will clean him and gut him thru the back side so the stiches want show when thier done and mount him to the board..
