Cryogenetics delivers systems for measuring sperm concentration and quality parameters of fish sperm. Our SDM6 Photometer is calibrated for accurate measurement of fish sperm concentration. The large variation in sperm concentration between males and ejaculates is well documented. This leads to reduced fertilization efficiency and lost production potential.
Cryopreservation reduces the investment need for land based breeding sites with 10–20%. Alternatively it increases egg production by 10–20% in any existing brood stock unit. Because milt is already available, you may stock the units with the desired number of females at the beginning of the season (based on the number of eggs needed). Then you can restock tanks with males as females are stripped and removed.
Cryopreservation of milt speeds up the introduction of new, profitable cultivation steps to the farmers with 25%. A breeding program based on cryopreserved milt has the potential to cut one year off the breeding cycle. For Atlantic salmon that means introducing the next cultivation steps every three years compared to the current four without losing genetic variation.
