Brood fish are collected in March when water temperatures reach 50-55 degrees Fahrenheit. Staff manually spawn the fish and then the fertilized eggs (that are smaller than the size of a dime) are transferred to hatching jars.
The eggs hatch in 10-15 days, and the newly hatched fish (called fry) are placed into hatchery ponds to continue growing.
After about a month, they have reached approximately 1-2 inches in length. These fingerlings are then stocked into the Tenn-Tom Waterway and its tributaries. ⁠
