Care of Fish
Do not gut your fish. If you cannot take your fish immediately to a taxidermist, wrap it in a very wet towel and place it in a plastic bag, making sure all the fins are flat against the fish's body to prevent breakage. Next, immediately freeze the fish. A fish frozen with this method can safely be kept in the freezer for months.
Note: A fish will lose its coloration shortly after being caught. A good color photograph taken immediately after the catch helps enable the taxidermist to duplicate the natural color tones of your particular fish.
