TOWARDS THE DEVELOPMENT OF TECHNOLOGIES FOR CRYOPRESERVATION OF FISH OOCYTES (CRYOCYTE)

摘要

The growth of intensive aquaculture requires efficient and effective methods to preserve gametes for higher flexibility in broodstock management, genetic improvement programs and preservation of genetic diversity. While methods for cryopreservation offish spermatozoa are well known, preserving maternally inherited important genetic factors has yet to be achieved. Methods for cryopreservation of yolk-laden fish embryos remain elusive so far, but immature or mature oocytes are a specific challenge.
