sturgeon fish
Community Q&A. The term âsturgeonâ actually refers to 26 different species of the acipenseridae fish family. Sturgeon are found swimming along the rivers, lakes and coasts of Eurasia and North America. Growing to a size of up to 18 feet (5.5 m) long, this large fish is harvested for both its meat and its roe. The roe is later turned into caviar and sold at specialty shops throughout the world.
