On the Cryopreservation of Spermatozoa of a Freshwater Table Fish, Labeo fimbriatus (Bloch)

An extender-cryoprotectant system is developed for the long-term storage of the spermatozoa of a common freshwater tablefish, Labeo fimbriatus which is an annual breeder. Five extenders and three cryoprotectants were used in the present study. The cryoprotectants were used in three different percentages, viz., 5%, 7.5% and 10%. The experiment was conducted for 90 days. The spermatozoa diluted in extender-V and cryopreserved with 7.5% DMSO gave best results.
