For developing marine shrimp industry through aquaculture technology, one of the major
constraints is non-availability of sufficient seed and spawners to produce seed at the desired
time. Cryopreservation of gametes of aquatic animals in contrast to the situation in other
vertebrates particularly mammals has met with a very limited success. Very few attempts have been made on cryopreservation of sperms in decapod crustaceans in general and marine shrimps in particular. Efforts are now being made continuously on cryopreservation and cryobanking of penaeid gametes. The viable spermatozoa of P. indicus and P. monodon havebeen successfully preserved in CMFRI
