Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Largemouth Bass Problem

LMB in PA typically grow pretty slow. An 8 year old largemouth is probably half way through it's life.

An interesting growth chart from a lake near my hunting cabin in PA:
Average age and growth of largemouth bass in Koon Lake
Age Inches
1 4
2 7
3 9
4 11
5 13
6 14
7 16
8 18

They electroshocked a 22", 6 pound 3 oz LMB they found to be 13 years old. Slower growth rates in northern waters mean longer life spans.
