i have seen many posts on what happen it a fish becomes illegal in your state let say a Ray for exsample ..many people ask do i have to get rid of or kill my fish ..will they come break down my door and steal my fish .( so the game warden then can take them home and have fish you don't ) ..lol NO in almost every state out there you will be able to get a permit to keep such fish ...that you owned before the law was made... your always grandfathered in ...a permit would be needed ..and in many states the permit would be free
