Cryo-Preservation Results In 94 Per Cent Fertility

CANADA & NORWAY - Cryogenetics Ltd. based in Norway and Tri-gen Fish Improvement Ltd. based in Agassiz, British Columbia has during a joint project established an innovative cryo-preservation protocol for milt from Coho salmon.

During a two-step trial period in the fall of 2009, milt from 25 males were cryo-preserved comparing existing/public methods to the Cryogenetics method.

A total of 20,000 eggs where fertilised and incubated to provide significant numbers to the tests. The Cryogenetics method provided a 94 per cent average. This is by far the best known results obtained by using cryo-preserved coho milt to fertilise eggs.

The project will continue in 2010 to verify these results, and to continue the work on establishing similar methods for milt from Chinook and Sockeye Salmon. It is expected that the cryo-prerservation technologies will have a positive impact on how breeding companies and conservation authorities can safely store and later use genes.

Cryogenetics Ltd. specialises in developing cryo-preservation technologies for fish milt and embryos, and provides commercial products on milt from Atlantic Salmon, Rainbow Trout and Cod.
