It is intended to provide a method of treating fish meat whereby the amount of so-called drip flowing out from fish meat, which is obtained by disassembling, cutting and forming landed fish and then freezing, in the course of the treatment and thawing can be largely reduced. This object is achieved by pre-drying molded fish meat, which has been prepared by disassembling landed fish and cutting them into various shapes, with a cold air so as to lightly dehydrate the surface part, dipping the fish meat in an aqueous solution of sodium chloride for a short period of time so that the fish meat surface turns into a gel to form a coating, vacuum-packaging it as such, further blowing a clean gas such as oxygen into the package to give a gas-containing package, then freezing it by the brine freezing method and storing in that state. Due to a series of the treating procedures as described above, the amount of the drip during thawing the fish meat is considerably reduced.
