Mechanisms of Polyploid Evolution in Fish: Polyploidy in Sturgeonsically improbable, whereas their allopolyploid origin is quite probable, as it has been confirmed by data on reticular speciation in vertebrates and experimental crossings in fish. The most probable hybrid origin of polyploid sturgeon species is confirmed by various data. The species with 120-chromo

The Developmental Anatomy of the Heart of the Sturgeon ,e embryonic and early post-hatching periods. The study examines identification of the early heart tube, cardiac loop formation, and the transformation of the tubular heart into a multi-chambered organ in a temporal sequence. Also included are the development of the heart valves and that of the epica

Hormonal Induction of Ovulation In Vitro in Sturgeon Fishesmedium. The use of 70% Ringer solution modified for sturgeons markedly increases the percentage of ovulated oocytes. However, the oocytes matured and ovulated under these conditions were characterized by low abilities of fertilization and subsequent development. The diluted (69%) Leibowitz medium pr

Dispermic Androgenesis as a Method for Recovery of Endangered Sturgeon Speciesic hybrids by dispermic androgenesis. The method of dispermic androgenesis, developed for sturgeon fishes, includes genetic inactivation of eggs, their insemination with concentrated sperm (to cause polyspermy), and heat shock to facilitate the fusion of male pronuclei. The restoration of the diploi

On Nutrition and Feeding Studies as the Basis for the Culture of Different Sturgeon Species very suitable tool and has proved feasible for several sturgeon species and, additionally, it could contribute to the development of a new productive activity..The breeding of fish in captivity depends on a series of determining factors, among which the design of optimized feeding practices for the
