Ossetra 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". 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. Today, Caspian Ossetra is facing extinction in its native habitat. Farming sturgeon is the only way to continue the production of high-quality caviar. Continuous drastic declines in natural sturgeon populations over the
Blittable types some examples of blittable types available in the .NET framework: Additionally, one-dimensional arrays of these types (including unsafe "fixed buffers") as well as complex types containing only instance fields (which includes "readonly" fields) of these types are blittable. The presence of static or const fields that are non-blittable does not cause the type to become non-blittable, because such fields play no part in marshalling. Complex types (that is structs or classes) must also have instance field layout of "Sequential" applied using the [StructLayout] attribute in order to be considered blittable by the .NET marshaler. Structs have this attribute applied automatically
