Norwegian invention: cryopreservation of fish embryos
The Norwegian company Cryogenetics AS has made a significant breakthrough by inventing a method for cryopreservation of fish embryos down to -130° C (-202° F). This is a major achievement as the world’s scientific community has pursued a method for cryopreservation of fish embryos over several decades without success.
The Cryogenetics AS scientific team, lead by Dr. Elisabeth Kommisrud, has over the past two years systematically approached the task of establishing protocols for cryopreservation of fish embryos. An Atlantic cod embryo was cryopreserved, thawed and developed normally before hatching. The fish was named «Coddy». Trials were repeated, optimized and patent applications were filed to protect the invention.
Due to factors such as global warming, pollution and over-fishing, several of the world’s fish stocks are facing low numbers and could soon to be extinct. Cryogentics AS’s new technology may be adapted to suit cryopreservation of embryos from several fish species and thereby save a stock for future use. A frozen embryo can at a desired point of time be thawed and continue its natural development. Due to the large egg production in most fish species, a significant number of offspring can be produced at spawning. For example, an Atlantic salmon will typically produce between 8.000 and 12.000 eggs per female.
The new technology from Cryogenetics AS also gives rise to the possibility of limiting the spread of diseases in fish farming, since selected genetic material can be transferred between regions with different health status in a more controlled and safe way than today.
Cryogenetics AS is anticipating this invention for cryopreserving fish embryos will have a wide area of application for companies and research institutions working with fish. Breeding companies, R&D companies, vaccine producers and public conservation programs can dramatically reduce costs and increase opportunities through this method.
Cryogenetics Ltd. will seek partnership with strong R&D groups to develop and adapt the technology for major fish species.
The company is actively supported by Innovation Norway.

Dear colleagues!
I was very much interested by your message on possibility cryopreservation embryos of fishes. Very important achievement.
Please, send articles where about it is written in more details.
In Russia, since 2000, we (The senior scientific researcher of the Petersburg university Margarita Manohina and I ) also take up the issue cryopreservation of embryos of fishes (model-danio рерио). The few (64) managed to be recovered after defrosting.
Results, however, while are reproduced very badly, and the main thing, is unpredictable. Rough cryoinjury we have learnt assurance reliability not to suppose. Unfortunately, these works are not financed, so we move ahead while with great difficulty. We informed on the researches at several international conferences in Russia and other countries.
With wishes of successes,

I am glad at last that this research work on cyropreserevation of embryos of fish was carried out successfully by your organization.I had also be thinking of how this can be done because ,I as a farmer ,extensionist,researcher,fish beeder,human developer(trainer) in the field of agriculture;your research findings is a break through for the entire fisheries world.I am very much available for any collaboration so as to embark on the cryopreservation of other fish species, i e.African cat fish(clarias spp).
I am a Nigerian,a graduate of agricultural management and extension,and also practicing fish farmer.
I shall send my c v and my business profile if need be.
have a wonderful week.

Dear Colleagues,
could you tell me more about this. I still have doubts about the reproducibility of these results. I donot buy the idea of cryopreservation of fish embryos as it is very difficult for me. If they have done it it is a breakthrough and COGRATs!
