This is how I mounted the huge perch my son caught while fishing with his grandpa and I. I used to practice taxidermy as a teenager, and mounted several fish by the skin mounting method. This is my first try making a taxidermy fish mount by making a sand mold and casting using fiberglass resin. I am very pleased with the results. Try it out yourself! I learned the hard way……spray the mold with non-stick cooking spray before you pour the fiberglass in!
