What is the sturgeon shovelnosse?

Sturgeon Shovelnose ( scaphirhynchus Platorynchus ), also called Hackleback or Switchtail, is a fish living only in Missouri and Mississippi of the United States. It is the most abundant type of sturgeon, the smallest type of fresh water and the only sturgeon that was commercially hunted in the United States. Sklage shovelnos, like the other Jespes, are appreciated for their meat and caviar. All species are endangered and even the most abundant species, the Sturgeon hundred, has a vulnerable state of preservation. Sturgeons are among the most valuable fish. There are sea and freshwater species and some live in both types of environments. Sturgeons are distributed in the northern hemisphere.

Shovelnoste Sturgeonsjsjsjsjs are light brown, with white belly. They have a flat snug -shaped snout, a long fiber attached to their tail fin and four curved barbels on the chin. Their abdomen are covered with weights, unlike the closely related palival Jeseren ( scaphirhynchus albus ), also Pocthrowing from the rivers Missouri and Mississippi. Sturgeons have a hard, board scale called ganoid scale. Their diet consists mainly of insect larvae, small crustaceans and fish and worms. Sturgeon Shovelnosse is also a host of parasitic larvae of a series of molluscs or shells and is the only species that hosts the Mussel Hickorynnut larvae ( olivaria ).

Shovelnose Sturgeons migrate upstream to behave for about three years. During the reproduction period, fish behavior changes and floats just on the surface. Women put eggs in fast moving water above the gravel.

eggs hatch three to five days after friction and hatchlings are transmitted downstream to the current. Like most JESEONS, the sturgeon of shovelnosse grows slowly. It is only able to breed when it is eight to ten years.

both meat and caviar shovelnose sturgeion are considered delicacies. BodyIt is often smoked and ROE can be referred to as a hackleback caviar. He became increasingly popular because the caviar endangered Sturgeon of the Old World, such as Beluga, has become more rare. It scares and excessive fishing represents a serious problem of shovelnos, because it is often or easy to choose and takes a long time to achieve maturity.
