I was wondering if it was legal for a fisherman to radio tag our just tag a catfish he catches to try and study the every day life of the catfish? I can catch a bunch of blues and would like to track them to see how they live ever day. This maybe exspinsive to buy the equipment to do if its is even legal to do unless you are with the fish and game department. It was done on the Bass Master tournaments this year and it showed some very good info. I would love to do a study on blue catfish by tracking precaught fish during ther normal every day life. Just wondering this maybe a unrealistick dream I have.
