Sterlet Sterlet The sterlet ("Acipenser ruthenus") is a relatively small species of sturgeon from Eurasia native to large rivers that flow into the Black Sea, Azov Sea, and Caspian Sea, as well as rivers in Siberia as far east as Yenisei. Populations migrating between fresh and salt water (anadromous) have been extirpated. Due to overfishing (for its flesh, caviar, and isinglass), pollution, and dams, the sterlet has declined throughout its native range and is considered vulnerable by the IUCN. Restocking projects are ongoing, and it has been introduced to some regions outside its native range, but the latter have generally not
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
