Farming of Siberian sturgeon (Acipenser baerii) for caviar production in Uruguay (Caviar obtaining)

Upon the end of raceway phase in raceways when fish are at 6 years of age, sturgeon females are slaughtered and caviar (eggs) is obtained. The photo shows female fish which are prepared before slaughtering. A female when slaughters measures about 1.5 meter in length and weighs about 8 kg. Caviar represents about 20% of a female weight. Considering the high value of caviar, the meat of males and spent females –although very good- is considered a byproduct to caviar. Usually each farm has its own slaughtering plant for processing and packing of caviar and meat.
