Biology and control of reproduction of sturgeons in fish farm

Over the last century the reproduction of sturgeon has been intensively studied par Russian scientists who established a technology for the ranching of alevins which included artificial fertilization of gametes taken from wild broodfish and larvae rearing. More recently, since 1970, major contributions originated from teams in the USA, the EU, Japan and Iran. A rather good knowledge of the reproductive physiology of sturgeon is now available: gametogenesis, reproductive cycle, ovulation, spermiation and fertilization. The complete life cycle was obtained in captive conditions allowing the production of juveniles and caviar
