to tell you the truth, i don't see much difference from killing a deer with the purpose of mounting it. There are 100's of hunting shows dedicated to killing trophy whitetails, whats the difference in fishing? Sure you put the bass back to let it grow, just like you can let a deer walk with the intent on letting it get bigger. Or if you feel like this deer or fish is the biggest you've ever seen or caught, why not save that trophy?
