Acipenser gueldenstaedti (Gueldenstaedt sturgeon)

Fish Acisseur Gueldenstaedti, more commonly known as Gueldenstaedt sturgeon, is a freshwater fish that belongs to the Family of Ecipenseridae. He is native to the hydrographic basins of the Urals, the Caucasus and the Volga, in Russia.

The Acissenger Gueldenstaedti is an imposing fish, with an elongated body and a massive head. Its color varies from dark gray to silver gray, with dark longitudinal stripes on the back and sides. The dorsal fin is thorny, while the anal fin is smooth. The tail is in the shape of a liver, with a caudal bifide fin.

Adult males can reach a length of 2.5 meters and weigh up to 70 kg, while the females are even larger, up to sizes up to 4 meters long and weigh up to 300 kg. Their life expectancy is around 50 years.

The Acissenger Gueldenstaedti is an oviparous fish, that is to say that he lays eggs rather than giving birth to young. The Frai period takes place in cold water, generally in winter or early spring. Eggs are incubated for about two months before turning into fry.

The diet of Acissessing Gueldenstaedti consists mainly of different types of fish, molluscs and crustaceans. They are opportunistic predators and are able to adapt to different types of food depending on what is available in their habitat.

Unfortunately, the Acissesser Gueldenstaedti is a endangered species of extinction due to water pollution, overfishing and destruction of its natural habitat. Many efforts are underway to protect this species and put it back in the wild.
