"Snagging"

Is that where you stick your arm up a hole under water and let that thing grab it and then yank it out of the hole ?

I know there is a huge difference between 75 lbs and 25 lbs, so there may be some difference in taste there.

How many years would it take to grow that size?

I started my search here at home. North America is home to two giant catfishes. Ictalurus furcatus, the blue catfish, is native to the Misssissippi, Ohio, and Missouri river basins. Angler Tim Pruitt, of Alton, Illinois, holds the record catch of this species weighin in at 124-pounds. He dragged out of the Mississippi River near Alton after a half-hour battle, the fish measured 58 inches long and 44 inches around. There is a record from the Missouri River of a 315 pound blue catfish that was caught "just after the Civil War."

The second giant is Pylodictis olivaris, the flathead catfish. The current world record, as of 1998, is a 123 pound monster caught in Kansas. Commercial catfishing operations report flatheads nearly 5 feet long and weighing in at 140 pounds. This was my first surprise. Many sources report that the blue catfish is the largest catfish in North America. However, according to the most recent world records, the flathead catfish currently holds the title. Maybe there are still a few giant old blue cats lurking deep in the Mississippi.
