In Pennsylvania, it typically takes a smallmouth bass (Micropterus dolomieu) about 6 to 8 years to grow to 17 inches, though growth rates can vary based on several factors:
Key Influences on Growth Rate:
Water Temperature – Optimal growth occurs in waters around 68–75°F. Colder waters can slow growth.
Food Availability – Diet rich in crayfish, insects, and smaller fish supports faster growth.
Fishing Pressure & Habitat Quality – Less stress and better habitat promote healthier and faster-growing fish.
Genetics – Some fish simply grow faster due to inherited traits.
Average Growth Benchmarks in PA Waters (approximate):
Age (Years)
Length (Inches)
1 4–6”
2 7–9”
3 10–12”
4 12–14”
5 14–16”
6–8 16–18”
So, reaching 17 inches would generally place a smallmouth at around 6 to 8 years old in Pennsylvania waters.
