The largest largemouth bass ever caught in New Hampshire was 10lbs 8 oz, by G. Bullpit. The trophy-sized fish was 25.8 inches long. 

G. Bullpit set the record in May of 1967 in the town of Brookline, New Hampshire. The unsuspecting largemouth bass was swimming around in Lake Potanipo.

To put the size into perspective, 10 lbs is the same weight as an adult cat. That’s a lot of fish to reel in! However, it’s not the biggest largemouth bass ever caught.

Biggest Largemouth Bass Ever Caught Worldwide

The world record for the largest bass ever caught was 22 lb, 4 oz by George Perry.

The largest largemouth bass ever caught worldwide was 22 lb, 4 oz, by George Perry. On June 2, 1932, George Perry set the undefeated world record. 

The trophy-sized fish was caught out of Lake Montgomery in southern Georgia. The record became one of the oldest world records for coveted saltwater and freshwater species

Japan Sets World Record Tie

On July 2, 2009, Manabu Kurita of Japan caught a largemouth bass that weighed 22 lb and 4.97 ounces. Manabu Kurita’s fish was an official tie for the world record of the largest largemouth bass ever caught. The incredible catch came 77 years after George Perry’s world record.

The fish Manabu Kurita caught was a Florida-strain largemouth bass. The monster fish was swimming around Lake Biwa, near Kyoto. 

If Manabu Kurita’s bass weighed 10lbs and 4.97 oz, why didn’t it break the world record of 10 lbs 4 oz? The International Game Fish Association (IGFA) rules declare that a fish must be 2 oz or more significant than the previous record. 

Manabu Kurita’s catch was less than 1 oz bigger than George Perry’s. But it still qualified for a tie!

Early dawn and late evening are prime fishing windows for bass. You’ll usually find a lot of tons of fish swimming around clean lake shorelines

Bow Lake 

Bow Lake in New Hampshire is a popular spot for largemouth bass fishing. The 1200-acre lake sits in the Southeastern part of the state. Anglers can enjoy 7 miles of shoreline. 

There are rocky areas, laydowns, and boat docks to explore. Along with largemouth bass, Bow Lake is an excellent spot for catching sunfish, perch, trout, and pickerel. When you’re done fishing, you can head over to one of New Hampshire’s fun aquariums to spot even more aquatic species.

Largemouth Bass Ice Fishing in New Hampshire

The largemouth bass isn’t a coldwater species. During the winter largemouth bass become lethargic. Icefishing is a great way to catch slow-moving bass.


New Hampshire is a great place to go ice fishing for largemouth bass. During winter, you can find largemouth bass in Martin Meadow Pond and Warren Lake, New Hampshire. 

When the lake ices over, they become lethargic–making them easier to catch. This is because the largemouth isn’t a coldwater species. 

Icefishing Tips

Stay close to the shoreline when ice fishing for largemouth bass. The shoreline is where the bass can find a lot of their preferred aquatic vegetation. 

Inactive bass like to lay in holding areas with a 25-30 ft range, seeking out soft bottoms. You’ll have to use slightly larger baits and heavier lines to reel in these large fish. 

Hatch Date Impacts Largemouth Bass Length

Young bass constantly grow and develop. It can be challenging to say how long until they’re fully grown.

Their life cycle depends on the length of the growing season, hatch date, and water temperatures. A largemouth bass’s hatch date helps determine the length. Early-hatched largemouth bass grows to be larger than late-hatched fish. 

Late-hatched largemouth bass grows the most initially. However, early-hatched fish catch up after the first month and continue to grow rapidly. Their enhanced size gives them the advantage of becoming piscivorous before late-hatched fish. 

Being able to eat fish means the early-hatched largemouth bass can continue to grow exponentially during the fall. By winter they have plenty of lipid reserves.

Average Age and Survival Factors for Trophy Bass

At what age do largemouth bass reach trophy size? The ages for trophy-sized largemouth bass range from 4 to 16 years old.

There are a lot of different factors that impact a largemouth bass’s odds of surviving long enough to become a monster-sized fish. 

During their first year of life, most young basses become eaten by predators. The ones who survive the juvenile stages risk being caught by anglers. 

The adult largemouth bass is prone to infection and diseases because of environmental stressors. Low dissolved oxygen is one of the environmental threats basses face.

Considering all the challenges, it’s incredible when a bass survives long enough to reach trophy size. What does a bass eat to grow so large? Find out what a bass diet looks like now!
