About Pallid sturgeon in brief
The pallid sturgeon is an endangered species of ray-finned fish. It is endemic to the waters of the Missouri and lower Mississippi river basins of the United States. The species takes 15 years to mature and spawns infrequently, but can live up to a century. A loss of its habitat is thought to be responsible for its decline. Efforts to prevent the species from becoming extinct have had modest success. It was the first fish species in the Missouri River drainage area to be listed as endangered, and a restoration of these areas is required if the species is to survive in the wild. The scientific name for the fish is derived from Scaphirhynchus, a Greek word meaning “spade snout” and albus which is Latin for “white’“. The word pallid means ‘deficient in color’ and compared to other species of Sturgeon, the pallid is noticeably paler. The fish is considered to be good-tasting, and its eggs have been used as caviar, although less commonly than those of many other sturgeons. The southern populations of pallid and shovelnose sturge populations have more hybrids than the northern populations. Hybrids are most common in the Atchafalaya River in Louisiana, and DNA sequencing in these hybrids showed a genetic distinction from pallidsturgeon. The northern populations are reproductively isolated and are genetically distinct from the southern populations, but the genetic variability between them and the southern population was found to be less than that between the shovelnosed sturch population and the northern population.
It’s the reason that some biologists have expressed concern of this ability of the two species to hybridize, based on the ability of this hybrid of two species of this species to create a new species of fish. The pallidSturgeon can grow up to 60 inches in length and 85 pounds in weight at maturity, but is much larger, averaging between 30 and 60 inches in length at maturity. It takes 15 years to mature, but it can live a century, and this species takes up to five years to reach maturity. The U.S. Fish and Wildlife Service placed the pallids on its endangered species list because few young individuals had been observed in the preceding decade and sightings had greatly diminished; the species was now rarely seen in thewild. It has been listed as a vulnerable species since the 1990s, but efforts to prevent its extinction have had limited success. Its closest relatives are the relatively common shovelnoses, which is still relatively common, and the critically endangered Alabama stur Sturgeon, which may soon become extinct. These three species belong to the subfamily Scaphirschinae, which has only one other genus, Pseudoscaphirchus. The three species are represented by three species found in west-central Asia, represented by the three species of Pseudirschus found in West-Central Asia.
