National Catfish Day is a national observance of the United States celebrating "the value of farm-raised catfish." The day was designated as June 25, 1987, by President Ronald Reagan, who issued the Presidential Proclamation after the U.S. Congress called for the day to be established in House Joint Resolution 178.
