Last Updated: November 07, 2011

Fish should be stocked at a rate no more than 1 inch of fish (length) per 3 to 5 gallons of water in the pond. Fish attain a greater size, do less damage to submerged plants, and remain healthier if stocked at rates below the capacity of the pond. A small circular pond, 5 feet in diameter and 18 inches deep holding around 160 gallons of water, will accommodate four to five 10-inch fish.
