Ossetra

Source animals

In Russian, there are different names for the species of sturgeon that live in various territories such as Beluga (Huso huso), Sevruga (Acipenser stellatus) and Sterlet (Acipenser ruthenus). The name Ossetra corresponds to the species Acipenser gueldenstaedtii, which is much smaller than Beluga sturgeon (Huso huso), and has a firmer texture. In the territory of the Russian Federation dwells another type of sturgeon, Siberian sturgeon (Acipenser Baerii), which is farmed all over the world because it can adapt to a wider range of habitats. It begins to produce caviar faster than Acipenser gueldenstaedtii.

History

Throughout the entire history of black caviar consumption, reference to Ossetra was made only to the fish that was caught first in Imperial Russia, then the USSR, and now in the Russian Federation.

Production

Today, Caspian Ossetra is facing extinction in its native habitat due to the fact that wild caught sturgeon are immediately slaughtered to determine their sex and egg-bearing condition. If male they have no eggs, and even if female they may not be in roe. Farm raised sturgeon by contrast are periodically scanned by harmless ultrasound to make the same determination. Continuous drastic declines in natural sturgeon populations over the past 30 years plus a high market demand for caviar have led the way for artificially cultivation of sturgeon for the production of caviar. Russia, Iran, members of the European Union, China and the USA were among the first; however, for the very same reasons countries outside the natural range of sturgeons also became involved (e.g. Uruguay, Arabian countries, Israel, Iran, and more recently Vietnam).

As with all other caviars, ossetra is traditionally served on blinis with crème fraiche, chopped hard boiled egg whites and chopped onions. Lower-grade varieties of caviar are used as stuffing in many seafood dishes, and some meat dishes. Caviar is often added to salads as well.
