Sperm cryopreservation in sturgeon with a special focus on A. sturio: chap. 35
Résumé
Cryopreservation is a technique of low-temperature conservation of genetic resources for an unlimited period of time The cryopreservation of sturgeon sperm has been problematic for many years, however, during the last decade a reliable methodology has been described that helped to maximize the fertilizing capacity of frozen sturgeon semen. This techique involves the use of methanol as cryoprotectant instead of the more conventional dimethyl-sulfoxide. The method has been successfully applied to Acipenser sturio and currently a cryopreserved gene bank is being developed for this species.
