Aquatic Species and Capability

  • RAINBOW TROUT are called rainbow trout because of the colorful pink to red lateral stripes on their sides. They tolerate waters which are associated with flood control dams. Their natural habitats consist of free flowing cool waters. Rainbow trout can grow as large as 52 pounds. Dale Hollow National Fish Hatchery (NFH) distributed 1,406,747 rainbow trout weighing 238,494 pounds in Fiscal Year (FY) 2012. This total includes 749,355 nine inch fish weighing 223,172 pounds, and 649,323 three to five inch fish weighing 14,241 pounds.
  • BROWN TROUT are brown to tan on the back and silvery on the lower sides and belly. They have black spots on the top and sides of the head and body and red spots scattered on the sides. These fish also like cool free flowing waters. Brown trout can grow as large as 40 pounds. Dale Hollow NFH distributed 295,825 brown trout weighing 42,831 pounds in FY 2012. This total includes 220,790 six to eight inch fish weighing 38,766 pounds, and 20,004 three to five inch fish weighing 856 pounds.
  • LAKE TROUT have small, light, irregular spots on a background varying from silvery or light green to dark green, brown, or black. They like cold waters, usually deep lakes or reservoirs, where they can find colder, well oxygenated water even in warm weather. Lake trout have been known to grow larger than 100 pounds. Dale Hollow NFH distributed 46,033 lake trout weighing 1,934 pounds in FY 2012. All of the 46,033 fish were five inches in length.
  • BROOK TROUT can be found in small streams, creeks, lakes, and spring-fed ponds. They prefer cool, clear water and are sensitive to poor water quality. This fish is confined to higher elevations throughout the southern portion of its range and is the only salmonid native to Tennessee. Brook trout are green to slate gray in basic coloration with a marbled pattern of lighter shades across the back, extending to the dorsal fin. The body has pale spots and a few red spots ringed by pale areas. The dorsal, adipose, and caudal fins have dark spots. Brook trout can reach a weight of 14 pounds but are generally much smaller. Dale Hollow NFH distributed 166,248 brook trout weighing 40,283 pounds in FY 2012. This total includes 124,539 nine inch fish weighing 39,585 pounds, and 41,709 three inch fish weighing 698 pounds.
  • BARRENS TOPMINNOW is an extremely rare fish occurring in springs and spring influenced streams on the Barrens Plateau in south-central Tennessee. Breeding males have red spots on a green or blue body with yellow on the fins. Non-breeding males, females, and juveniles are pale brown with scattered dark spots on the sides. Dale Hollow NFH distributed 429 Barrens topminnows to two sites located in Franklin County, Tennessee in FY 2012.

FAQs:

Q: What kind of fish do you raise?

A: Dale Hollow National Fish Hatchery is a coldwater fish hatchery which means that we raise fish that do best in water temperatures between 40 degrees and 60 degrees Fahrenheit. The coldwater species currently in production at this facility are rainbow trout, brook trout, brown trout, and lake trout. The water being supplied to the hatchery to raise trout is too cold to raise Barrens topminnows. This species is raised in closed, indoor recirculation systems where water temperature can be controlled.

Q: How big are the fish when they are released?

A: The majority of rainbow trout reared at this facility are used for programs requiring continuous stocking of nine inch fish in waters which typically experience intense fishing pressure and little natural reproduction. A nine inch fish is considered large enough for anglers to keep. Waters with few predators and ample food supply are stocked with two to five inch fingerlings. This technique is very cost effective because large numbers of fish can be stocked without having to incur high feed costs. Nature grows the fish to a harvestable size.

Lake trout are stocked at a size of six inches. These fish are stocked into reservoirs having conditions conducive to good growth and survival.

Brown trout are managed by stocking tailwaters that will support small fish with four to six inch fingerlings. Waters which have proved not to generate high survivability when stocked with smaller fish, receive stockings of six to eight inch brown trout. Nature grows these fish to a harvestable size.

Barrens topminnows only grow to about four inches in length. The fish grown-out at Dale Hollow NFH average two inches in length when they are stocked into the wild.

Q: Where do you stock the fish?

A: All of the brown trout, lake trout, and brook trout and most of the rainbow trout reared at Dale Hollow NFH are stocked in and below U.S. Army Corps of Engineers (Corps) and Tennessee Valley Authority (TVA) impoundments in Tennessee.

Fingerling rainbow trout are supplied to the state of Georgia. These fish are transferred to state and federal hatcheries where they are grown to a harvestable size and are subsequently stocked in and below Corps and TVA impoundments in Georgia.

Harvestable size rainbow trout are stocked in the tailwater of Lewis Smith Reservoir in Alabama to mitigate for federal water development projects and in return for Gulf Coast striped bass fry and eggs which are utilized by federal warmwater hatcheries in an ongoing Gulf Coast striped bass restoration effort.

Harvestable size rainbow trout are stocked into non-mitigation waters under a cooperative agreement with the Tennessee Wildlife Resources Agency. This program provides recreational fishing opportunities at Ft. Campbell, the Veterans Administration hospital in Murfreesboro, Calderwood and Chilhowee Reservoirs, and numerous winter trout fishing events held throughout middle Tennessee.

Barrens topminnows are stocked into springs and spring influenced streams in south-central Tennessee (Coffee and Franklin Counties). Most of these stocking locations are located on private land.

Q: How do you get the eggs from the fish?

A: Trout spawning operations are not conducted at the hatchery. Fertilized eggs are received from other hatcheries by overnight mail in special egg shipping cartons and are placed into hatching jars. Once the eggs hatch, the sac fry are placed into indoor concrete tanks. After the larval fish absorb the yolk sac and are ready to begin feeding, the fish are weaned onto a commercial trout diet.

Rainbow trout eggs are generally available from August through the first of May. Brown and lake trout eggs are only available from the middle of October to the end of December. Brook trout eggs are available from the middle of December to the end of January.

Q: Stocking trout is not “natural” is it?

A: Stocking non-native species of trout is not “natural” but neither are dams. Dams perform critical functions such as flood control and hydro-electric power generation, but there is a down side to dams. Construction of a dam, regardless of its type, alters the entire river ecosystem.

Dams often produce large, deep reservoirs in which the water stratifies into thermal layers
during the summer. The water released downstream into the tailwater comes from a deep, cold layer. This newly created coldwater habitat does not provide conditions necessary for populations of native warmwater fish to be self-sustaining. Trout stocking is carried out in order to utilize the available coldwater habitat and to “mitigate” for the impacts that these water development projects have on the respective river ecosystems.

Q: Are the states involved with fishery mitigation?

A: Southeastern state natural resource agencies make most of the management decisions regarding the various coldwater tailwater and reservoir fisheries, operate hatcheries that rear additional trout to meet mitigation needs, and assist the federal hatcheries with fish distribution.

Q: How much does it cost to raise a pound of trout?

A: It cost approximately $2.67 to raise one pound of trout in Fiscal Year (FY) 2010.
