Abstract It is possible to show if a fish has been frozen or not by examining the eye lenses. A positive reaction is shown by opacity in the lens medullas, and the fish must be cooled to at least— 4.8° for the effect to occur. It is only masked by stowage in ice for more than 16 days, or by salting the fish for 1 day or more before freezing. The mechanism of the phenomenon is deduced.
