Fish semen cryopreservation has important applications in the following fields: (1) in aquaculture, for synchronization of artificial reproduction, for efficient utilization of semen, and for maintaining the genetic variability of broodstocks; (2) in biodiversity, for gene banks of endangered species and of autochthon fish populations; and (3) in temporary unlimited supply with material for research as, for example, for toxicological tests or interspecific breeding.
