Cryogenetics is continuously working to develop new products and services, and to improve our existing portfolio
Many aquaculture species have gender-specific traits that favor the farming of one gender; for instance caviar production favors females, whereas meat production commonly favor males, due to their higher growth rate. Cryogenetics offers a PCR-based gender test that can determine the gender of fish at an early stage using a small tissue sample, such as a fin clip or scale. However, production of monosex stock at the time of fertilization is a more efficient and elegant solution. Our R&D department therefore has initiated a project that aims to develop a product that will select the gender (with a >90% efficiency) of the fish before fertilization. This will be a future service offered from Cryogenetics that will see application in the aquaculture industry.
Cryopreservation procedures are developed for mammalian embryos, and is an established technology for e.g. human and bovine reproduction. Embryo preservation is the only way to preserve genetic material from both parents when this is essential.
Successful cryopreservation of fish embryos has for long remained a challenge for researchers worldwide. This is considered a challenging procedure due to many reasons. Among these are the complicated “compartmentalized” structure of fish embryos, with a yolk sac and chorionic membrane. In 2011, Cryogenetics demonstrated a “proof-of-concept” cryopreservation of a Atlantic cod embryo. This led to a comprehensive development project in cooperation with partners to develop cryopreservation protocols for embryos from three species; Atlantic salmon (Salmo salar), Atlantic cod (Gadus morhua) and zebrafish (Danio rerio).
We are continuously working to develop cryopreservation protocols for sperm from new fish species, both on clients’ request and based on our own market analysis. Since 2011 we have successfully developed protocols with good results for sperm from Arctic charr (Salvelinus alpinus), white sturgeon (Acipenser transmontanus) and sablefish (Anoplopoma fimbria) in collaboration with partners from the industry.
