| Sumario: | The development of marine fish farming requires the availability of domesticated fish strains presenting optimum growth and reproduction levels. Moreover, breeding programs, need efficient cryopreservation methods for both gametes and embryos, making it possible to establish comprehensive genetic banks distributing selected individuals within the aquaculture industry. However, both controlled freezing and vitrification techniques have resulted in very low survival rates for fish embryos, mainly due to the embryo's low permeability to cryoprotectants and their remarkable water content (hydration). In this short review, we summarise current knowledge of the biological mechanisms leading to the hydration of fish eggs. Some of the recent findings in this field may be the starting point for biotechnological strategies directed towards the development of new cryopreservation methods for female gametes and embryos from aquacultural fish species. |
