Animals, coyote sized or smaller, should not be skinned unless by a professional. Don't gut the animal. Small mammals, especially carnivores, will spoil quickly because of their thin hide and bacteria. If you can't take the small game animal immediately to a taxidermist, as soon as the carcass cools completely, put it in a plastic bag and freeze it.
Do not gut the bird. Rinse any blood from the feathers with water. Take the bird immediately to your taxidermist or freeze it. Put the bird into a plastic bag for freezing, being careful not to damage the feathers, including the tail. If the bird's tail feathers do not fit in the bag, do not bend them. Let the tail stick out of the bag and tie the bag loosely.
Do not gut your fish.
If you cannot take your fish
immediately to a taxidermist, wrap it in a very wet towel and put it in a plastic bag,
making sure all the fins are flat against the fish's body (to prevent breakage) and
freeze it. A fish frozen in this manner can safely be kept in the freezer for months.
Note: A fish will lose its coloration shortly after being caught. A good color photograph immediately after the catch may enable the taxidermist to duplicate the natural color tones of that particular fish.
