This past spring I traveled with fellow KQED QUEST producer Gabriela Quirós to the Sacramento area to film at Sterling Caviar, one of two Californian companies currently producing this delicacy.
This company raises white sturgeon, one of two native species to California (the other is green sturgeon). They originally obtained their stock from the Sacramento River. Once they were able to create their own brood stock for the next generation, they no longer needed to harvest fish from the river.
