Some data on gametes preservation and artificial insemination in teleost fish
Gametes preservation is usually short (several hours to several days) at temperature above O°C. At subzero temperature sperm fertilizing ability may be kept for several weeks while egg fecondability does not exceed one week. Techniques of sperm cryopreservation in liquid nitrogen are now established for some marine fish species but have to be improved for salmonids.
