There is no use in a back-up system that cannot be trusted. With Cryogenetics systems, when cryopreserving a line you will not feel that you have to keep several tanks of live fish from that line, “just in case”.
Our new cryopreservation protocol has shown an average and stable fertilization rate of >80%. In addition, and perhaps the most result is that there have been no “zeroes” in the fertilization tests! We offer to run demonstrations of the fertilization with the cryopreserved sperm to make you confident that this will work.
