A REVIEW ON SPERM CRYOPRESERVATION OF FRESHWATER FISH

摘要

Cryopreservation of sperm is a valuable technique for artificial reproduction, genetic improvement and biological conservation programmes (Chao and Liao, 2001). Fish sperm cryopreservation has been practicised in > 200 fish species (Billard and Zhang,2001). Nevertheless, because of clear intra- and inter-specific differences observed in sperm characteristics (Ciereszko, 2008); some key parameters (e.g. ionic composition, osmolality) should be considered when cryopreservation methods for sperm are developed. Cryopreservation of sperm of carp (Cyprinus carpio), tench (Tinea tinea), perch (Perce fluviatilis), paddlefish (Polyodon spathula) and European catfish (Silurus glanis) is summarized in this review.
