If one jumps in your boat,or you snag ,or catch one please cut its gills before you throw it back.If I go fishing at Ky or Barkley Lake and get near the dams I will go and throw a crank bait for a while and almost always catch Asian carp and it is illegal to release them alive.I see others catch or snag them,cuss them but turn around and just release the fish,makes no sense to me.I always offer fish to someone who may wish to eat them or cut gills before I release them.
