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.

Yes, you are right. Today is the National Catfish Day! That's why we put the picture of this 9-feet-long 646-pound-weight Mekong giant catfish here. Now, all you need is about 500 beers and 4000 hush puppys!
For current USDA Catfish processing data, check out this recent survey issued by the National Agricultural Statistics Service. For some reason, Catfish processing is down by 9%! http://www.nass.usda.gov/Publications/Todays_Reports/reports/catf0510.pdf
