Fish Stocking Density Per Acre Pond Calculator
Calculate fish stocking numbers for a pond from surface acres and a target stocking rate, for bluegill, bass and catfish in a balanced community.
How This Calculation Works
Fish numbers equal surface acres times the stocking rate per acre for each species. Surface acres is length times width divided by 43,560. A balanced community might stock 500 bluegill and 50 bass per acre, scaled to the pond's area.

Common Questions
How many fish should I stock per acre?
A balanced community stocks about 500 bluegill and 50 largemouth bass per acre, with optional channel catfish. Rates vary with the pond's fertility and goals. Stock fingerlings in the fall.
What is a balanced fish community?
A balanced community pairs a prey species like bluegill with a predator like largemouth bass in the right ratio so neither overpopulates. The bass control the bluegill numbers, and the bluegill feed the bass. An unbalanced pond produces stunted fish.
When should I stock a new pond?
Wait until the pond has filled and the food chain of plankton and insects is established, usually a few months after filling. Stock fingerlings in the fall when water temperatures are moderate. Avoid stocking before the pond stabilizes.
Can I stock catfish with bass and bluegill?
Yes, channel catfish can be added to a bass-bluegill pond, but they compete for food and may need supplemental feeding. Stock them at a lower rate. Catfish are often managed as a put-and-take species.
