| Research Abstract |
In order to reduce mechanical stress induced by external ice formation in a freezing of fish egg, we suggest a new method using liquid meniscus. We have developed the meniscus holder that holds the liquid-meniscus up to the top of the fish egg. The membrane of the fish egg is coated by the thin film of torehalose aqueous and can be protected from the external ice formation. Also, we used the dehydro-freezing in order to reduce the rupture due to the internal ice formation. The experimental results show that the fish eggs with meniscus holder have a high shape-preservation rate after the thawing.
