A Colorado teenager landed what appears to be the next Colorado state-record striped bass.

Isaac Sprecher, 18, hooked the 31-pound, 8.4-ounce striped bass while fishing with his girlfriend at McIntosh Lake Friday. The fish measured 41 inches long, with a girth of 26 inches.

Sprecher started casting from McIntosh’s south shore around 5 p.m., according to the Denver Post. He told the Post that he realized he had a “pretty good-sized fish” once it took his bait and started pulling away.

“It took 20 minutes to get where I could actually see the fish,” Sprecher told the newspaper.

The bass was officially weighed at Bennet’s Bait and Tackle Saturday morning. If certified, Sprecher’s bass will smash the previous record held by a 15-pound, 11-ounce striper caught in 2009.
