A 1000-kg, 4.17-m-long beluga fish from the Volga River (National Museum of Tatarstan, Kazan, Russia) Among all extant bony fishes, the beluga sturgeon rivals the ocean sunfish (Mola sp.) as the most massive fish and is the second-longest bony fish after the giant oarfish (Regalecus glesne). It is the largest freshwater fish in the world.

An ultrasound is used to determine the correct timing. [51] [52] Removing the caviar by massage may yield higher quality and a more sustainable source ...
