My son is 2 ˝ and knows much better than that. This year is his first year fishing and at first he didnt understand why we released some of the fish. After a few short trips he learned if were not going to eat it , then it gets released. If it's to small it gets released.
Makes me proud when were otw to the fishing hole and he ask if we need fish to eat .
Still working on not hooking daddy during the cast lol, thank the lord for tough skin
