The benefits of cryopreservation in aquaculture species include the following (#2):
1. Cryopreservation can be used to improve hatchery operations by providing sperm on demand and simplifying the timing of induced spawning.
2. Frozen sperm can enhance efficient use of facilities and create new opportunities in the hatchery by eliminating the need to maintain live males.
3. Valuable genetic lineages, such as endangered species, research models or improved farmed strains, can be protected by storing frozen sperm. This could be critical for marine species such as shellfish, where valuable broodstocks must be stored in natural waters.
4. Sperm can be used in breeding programs to create new, improved lines and shape the genetic resources available for aquaculture operations. A dramatic example of this is in the dairy industry, which relies almost entirely upon cryopreserved sperm to produce improvements in milk yields.
5. Cryopreserved sperm of aquatic species will likely become an entirely new industry within the coming decade. Large, highly valuable global markets for cryopreserved sperm of aquatic species are on the horizon.
