Colton Lambert, 12, caught a Maryland-record largemouth bass while fishing at a farm pond in his hometown of Huntingtown on July 31.
The fish weighed 11 pounds, 6 ounces and was 26 inches long and 18 inches around.
Lambert caught the fish using a spinning rod loaded with an 8-pound test line and a plastic worm, rigged weedless and without a weight.
Fisheries biologist Keith Lockwood verified that proper procedures were followed and identified the fish as the freshwater largemouth bass state record.
Lockwood said the fish could have easily weighed more if it had been in a fattened condition.
The previous record of 11 pounds, 2ounces was held for nearly 30 years by Rodney Cockrell.
