How long does it take for a largemouth bass to reach its adult size?

Bass mature at different rates. Males can spawn at three years of age, females four. Males grow six inches a year in warm climates, females five, but these rates are for the first two years, then the females catch up and outgrow the males. Females of five years are around 19-22 iches long and weigh between five and seven pounds. Males that age are 15-17 inches long, and weigh 2-3 pounds. The largest male largemouth ever documented was "Bad Leroy Brown", a fish caught by professional Bass angler Tom Mann, and kept in a giant aquarium with other fish in Mann's Tackle store in Alabama. At his death, Leroy weighed seven pounds.
