RG, if you should happen to catch that "whopper" that eats all those crawfish around Rattlesnake, what you can do is take a bunch of measurements of the fish (alive) such as the length, girth, point of tail to point of tail, and take several closeup photographs. The more measurements, the better. If you happen to carry a scale, record the fish's weight. Then put the fish back in the water to live another day.
Take your data and pictures to a quality taxidermist and they will, utilizing a styrofoam or other type of plastic mold, re-create your fish for you to hang over the headboard, fireplace, front door, etc..
The cost, though not cheap, is not much different than bringing in a "whopper", hoping that the taxidermist can get the skin off with no damage and recreate the fish.
Want a fish fry??? stick with the smaller fish. Above all, have fun fishing.
