The Natchitoches National Fish Hatchery is a federal, warm water fish hatchery located in Natchitoches, Louisiana, United States. Natchitoches is involved in spawning, hatching and rearing young fish. [1]
Natchitoches National Fish Hatchery is along the Cane River and has 53 ponds, each approximately 0.8 acres (3,200 m2) in area. [2] In addition, the facility has the Harold B. Wales Environmental Education Classroom, which is used for kindergarten through twelfth grade and for teacher workshops. [3] The classroom seats 32 students and has 16 student grade dissecting microscopes. [4]
Natchitoches handles six species of fish, in addition to the Alligator snapping turtle and the Louisiana pearlshell mussel.
The paddlefish (Polyodon spathula) is the only remaining member of the family Polyodontidae. [5] Paddlefish are spawned and raised at Natchitoches until they are approximately six to ten inches (254 mm) in length, before they are released into the wild. [6]
Striped bass (Morone saxatilis) are members of the sea bass family. Natchitoches National Fish Hatchery is working to restore the historical range and population levels of these fish. [7]
The Pallid sturgeon (Scaphirhynchus albus) is a member of the sturgeon family. The hatchery is working to develop spawning and culture techniques to raise a large number of Pallid sturgeon. [8] Workers at the hatchery hope to raise enough of these fish to take the species off of the Endangered Species List. [9]
The Channel catfish (Ictalurus punctatus) is a member of the family Ictaluridae. Natchitoches works to raise many of these fish for release into the wild.
The Largemouth bass (Micropterus salmoides) is the most desired of all freshwater game. [10] Because of this, these bass require the attention of resource management agencies. Natchitoches National Fish Hatchery raises over 1 million largemouth bass every year.
The Bluegill (Lepomis macrochirus) is a fish that is quite easy to catch. The hatchery raises many of these fish every year.
Sturgeon is the common name for the 28 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous, and are descended from other, earlier acipenseriform fish, which date back to the Early Jurassic period, some 174 to 201 million years ago. They are one of two living families of the Acipenseriformes alongside paddlefish (Polyodontidae). The family is grouped into four genera: Acipenser, Huso, Scaphirhynchus, and Pseudoscaphirhynchus. Two species may be extinct in the wild, and one may be entirely extinct. Sturgeons are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. A Maastrichtian-age fossil found in Morocco shows that they also once lived in Africa.
Paddlefish are a family of ray-finned fish belonging to order Acipenseriformes, and one of two living groups of the order alongside sturgeons (Acipenseridae). They are distinguished from other fish by their elongated rostra, which are thought to enhance electroreception to detect prey. Paddlefish have been referred to as "primitive fish" because the Acipenseriformes are among the earliest diverging lineages of ray-finned fish, having diverged from all other living groups over 300 million years ago. Paddlefish are almost exclusively North American and Chinese, both extant and in the fossil record.
The American paddlefish is a species of ray-finned fish. It is the last living species of paddlefish (Polyodontidae). This family is most closely related to the sturgeons; together they make up the order Acipenseriformes, which are one of the most primitive living groups of ray-finned fish. Fossil records of other paddlefish species date back 125 million years to the Early Cretaceous, with records of Polyodon extending back 65 million years to the early Paleocene. The American paddlefish is a smooth-skinned freshwater fish with an almost entirely cartilaginous skeleton and a paddle-shaped rostrum (snout), which extends nearly one-third its body length. It has been referred to as a freshwater shark because of its heterocercal tail or caudal fin resembling that of sharks, though it is not closely related. The American paddlefish is a highly derived fish because it has evolved specialised adaptations such as filter feeding. Its rostrum and cranium are covered with tens of thousands of sensory receptors for locating swarms of zooplankton, its primary food source. The only other species of paddlefish that survived to modern times was the Chinese paddlefish, last sighted in 2003 in the Yangtze River in China and considered to have gone extinct no later than 2010.
The National Fish Hatchery System (NFHS) was established by the U.S. Congress in 1871 through the creation of a U.S. Commissioner for Fish and Fisheries. This system of fish hatcheries is now administered by the Fisheries Program of the U.S. Fish and Wildlife Service (Service), an agency within the United States Department of the Interior.
The lake sturgeon, also known as the rock sturgeon, is a North American temperate freshwater fish, one of about 25 species of sturgeon. Like other sturgeons, this species is a bottom feeder and has a partly cartilaginous skeleton, an overall streamlined shape, and skin bearing rows of bony plates on the sides and back.
A fish hatchery is a place for artificial breeding, hatching, and rearing through the early life stages of animals—finfish and shellfish in particular. Hatcheries produce larval and juvenile fish, shellfish, and crustaceans, primarily to support the aquaculture industry where they are transferred to on-growing systems, such as fish farms, to reach harvest size. Some species that are commonly raised in hatcheries include Pacific oysters, shrimp, Indian prawns, salmon, tilapia and scallops.
The delta smelt is an endangered slender-bodied smelt, about 5 to 7 cm long, in the family Osmeridae. Endemic to the upper Sacramento-San Joaquin Estuary of California, it mainly inhabits the freshwater-saltwater mixing zone of the estuary, except during its spawning season, when it migrates upstream to fresh water following winter "first flush" flow events. It functions as an indicator species for the overall health of the Delta's ecosystem.
The shovelnose sturgeon is the smallest species of freshwater sturgeon native to North America. It is often called hackleback, sand sturgeon, or switchtail. Switchtail refers to the long filament found on the upper lobe of the caudal fin. Shovelnose sturgeon are the most abundant sturgeon found in the Missouri River and Mississippi River systems, and were formerly a commercially fished sturgeon in the United States of America. In 2010, they were listed as threatened under the U.S. Endangered Species Act due to their resemblance to the endangered pallid sturgeon, with which shovelnose sturgeon are sympatric.
The pallid sturgeon is an endangered species of ray-finned fish, endemic to the waters of the Missouri and lower Mississippi river basins of the United States. It may have even reached the St. Croix River before colonization.
C.J. Strike Reservoir is a reservoir located in southwestern Idaho. Its main recreational features include the C. J. Strike Dam and its 7,500-acre (30 km2) reservoir, an impoundment of the Snake River and Bruneau River. This in turn provides excellent fishing and boating opportunities along with, to a lesser extent camping and hiking.
The Persian sturgeon is a species of fish in the family Acipenseridae. It is found in the Caspian Sea and to a lesser extent the Black Sea and ascends certain rivers to spawn, mainly the Volga, Kura, Araks and Ural Rivers. It is heavily fished for its flesh and its roe and is limited in its up-river migrations by damming of the rivers. Young fish feed on small invertebrates, graduating to larger prey such as crabs and fish as they grow. The threats faced by this fish include excessive fishing with the removal of immature fish before they have bred, damming of the rivers, loss of spawning areas and water pollution. The International Union for Conservation of Nature has listed the fish as critically endangered and has suggested that the increased provision of hatcheries could be of benefit.
The Russian sturgeon, also known as the diamond sturgeon or Danube sturgeon, is a species of fish in the family Acipenseridae. It is found in Azerbaijan, Bulgaria, Georgia, Iran, Kazakhstan, Romania, Russia, Turkey, Turkmenistan, and Ukraine. It is also found in the Caspian Sea. This fish can grow up to about 235 cm (93 in) and weigh 115 kg (254 lb). Russian sturgeon mature and reproduce slowly, making them highly vulnerable to fishing. It is distinguished from other Acipenser species by its short snout with a rounded tip as well as its lower lip which is interrupted at its center.
The Neosho National Fish Hatchery is the oldest federal fish hatchery in operation today. It is one of 69 fish hatcheries operated by the US Fish and Wildlife Service. It was established in 1888.
The Southern California Steelhead Distinct Population Segment (DPS) occurs from the Santa Maria River to the Tijuana River at the United States and Mexican Border in seasonally accessible rivers and streams. Steelhead in the Southern California Steelhead DPS, much like its relatives further north, requires sufficient flows in their natal streams to be able to return from oceans and lakes to spawn. Due to the extended periods of drought throughout their range, Southern California steelhead are most commonly seen during periods of increased rainfall, such as El Niño events. Declared federally endangered in 1997, the geographic range of the DPS when first listed extended from the Santa Maria River south to Malibu Creek. In 2002 steelhead were discovered in San Mateo Creek on the county line of Orange and San Diego counties. With this discovery the range of the DPS was extended to include Los Angeles, Orange, and San Diego counties.
The Gavins Point National Fish Hatchery is a fish hatchery administered by the U.S. Fish and Wildlife Service, located approximately 4 miles west of Yankton, in Yankton County, South Dakota, United States. The hatchery is located just below Gavins Point Dam, near the Missouri River.
Exotic and Unusual Fishes of North America is the name of a series of PBS documentary television specials about three species of American fish: The Alligator Gar: Predator or Prey?, The Paddlefish: An American Treasure, and Sturgeon: Ancient Survivors of the Deep. They were presented by KUHT Houston television station, and aired in the United States from 1992 to 1995.
