According to the post, Begley was using "cut suckers" for catfish bait. Instead, he reeled in the 61.5-inch (over 5 feet) sturgeon -- with the help of his fiancée, Kathy Trent, officials wrote on Facebook.
Per Tennessee law, Begley released the sturgeon back into the river.
According to the Facebook post, the sturgeon was almost 30 years old.

"Regional Fisheries Program Coordinator Bart Carter says the fish is nearly 30 years old and is from a restoration effort that began in 1992 when 3,200 lake sturgeon were released into the river," the Tennessee Wildlife Resources Agency wrote.
