The goal of this project is to develop cryopreservation and laser-warming technology to demonstrate a survival rate greater than 3% for golden shiner (fish) embryos. This project is part of the University of Minnesota Engineering Research Center for Advanced Technologies for the Preservation of Biological Systems (ATP-Bio). The ATP-Bio project teams seeks to develop technology that can stop biological time through temperature control in order to biopreserve or cryopreserve biological systems.
Why do this?
Cryopreservation of fish embryos could improve the productivity of the Minnesota aquaculture industry by enabling farmers to produce a continuous supply of gametes year-round and reduce the cost of broodstock maintenance. For many species such as walleye, cryopreservation could also be an important strategy to ensure against the loss of these species due unexpected disease, reproductive failures, or invasive species. Cryopreservation of fish embryos could also enable preservation of genetic lines for research.
Support for this project came from Minnesota Sea Grant's 2020-2022 biennial request for proposal solicitation.
