In the ’70s the first business initiatives for the breeding of sturgeons start to develop in Italy, France and USA.
In 1998, CITES (Convention on International Trade in Endangered Species) includes in the list of species under protection all fish of the Acipenser family (sturgeons and spatulas). The world begins to seriously think about the consequences of uncontrolled fishing. In 2006 fishing is completely banned in the Caspian Sea. In Calvisano, Calvisius farms set a record in the production of caviar with 25 tons of sturgeon roe.
