bassin

As a kid in the late 80's or possibly early 90's I remember the missouri conservation department (or possibly another company) had tagged crappies and maybe bass that you could catch and turn in for a reward. I remember a paper or poster with the fish drawn on it with their names and what each one was worth if it was caught. I am looking for any help with this? What was the event called and I would really like a copy of the flyer or poster? Thanks for any help in advance.
