The development of r eliable methods for cryopreservation of fish gametes and embryos will be highly impactful for aquaculture, fisheries research, and biodiversity preservation. However, success has been elusive for aquatic and other yolk- laden embryos due to their large size (mm scale) and low permeability to anti-freeze chemicals (cryoprotectants). Our group has developed an ultra-rapid laser warming technology that can re liably rewarm different millimeter scale biological systems ( cells, embryos, and larvae) with minimal use of cryoprotectants . Recently, we demonstrated that rapidly cooled (i.e., vitrified) zebrafish embryos, when microinjected with CPA and gold nanoparticles, can be revived with a millisecond pulsed laser . Since gold nanoparticles are highly efficient plasmonic absorbers, they can induce warming rates exceeding 10 million K /min to overcome dangerous ice formation and revive viability. The rewarmed zebrafish embryos were able to hatch, swim and mature to produce viable offspring. Beyond our success in zebrafish , the laser nanowarming platform has enabled the successful cryopreservation of embryos from other fish, corals, and shrimp. With improvements in the automation of droplet vitrification and storage, large- scale adoption and dissemination of this technology can be made possible. In this talk, we will discuss recent improvements and limitations of this approach towards building a “Cryo-Seed Bank” for aquatic species.
