The two photos show the river culture of sturgeon in cages in Uruguay. Cages used are square where each cage measures 6m x 6m x 3m depth. The three species/varieties of sturgeon are: Russian sturgeon (Acipenser gueldenstaedtii), Siberian Sturgeon (Acipenser Baerii) and Sterlet (Acipenser Ruthenus).
It is believed that raising sturgeons in River Negro (Rio Negro) for all time provides a culture environment similar to the wild conditions and hence enjoy excellent sanitary conditions as reflected in the ideal maturation as well as the high growth rates.
After two years of initial stocking, sturgeon stocks are sexed whereas females are directed to caviar production (when they are mature) while males are directed to fattening units for meat production.
