If the frozen sturgeon meat is sealed, it is completely edible. Don't say frozen for half a year, even if it is frozen for half a year, it can still be eaten (as long as it is not thawed and frozen in the middle).

Carnivorous foods can be frozen in the refrigerator for half a year, one year, two years, or even many years. (provided that there are no accidents such as power failure and refrigerator failure during freezing, which will lead to the thawing of frozen food.)

Not long ago, it was said on the Internet and in the news that the named "zombie meat" had been frozen for decades. Isn't it still on the market now, and many people eat it?
