I too was curious. Your answer and more.

Marine Harvest is the world’s leading fish farming company - White sturgeon

http://www.marineharvest.com/species-products/white-sturgeon.html
As a pioneer in the farming of white sturgeon, Marine Harvest has been raising white sturgeon in the Sacramento Valley of California since the early 1980s.

Male sturgeon are harvested for their meat when they weigh about 10kg. Females that are selected for caviar production remain in the fish farm an additional 5–7 years before they mature and the caviar can be harvested.

White sturgeon meat is a nutritious delicacy and is available as whole fish, bullets, skin-on fillets, skinless fillets and hot and cold smoked sturgeon.

When the female begins to ovulate she releases hundreds of eggs to show she is ready. She is placed on a stretcher with fresh water running over her gills, and all the eggs are removed. The female can be used for spawning again in future years, but not for making caviar.

Mark Arnao, executive sous chef with Atelier, a four-star restaurant in New York's Ritz-Carlton hotel, said the caviar from farmed white sturgeon is good enough for the exclusive eatery. "The taste is really very good," he said.

Sturgeon can grow to hundreds of pounds, and some of the farm-raised fish weigh as much as 150 pounds. The eggs can make up more than 10 percent of the body weight. But despite their bulk, caring for the fish is a delicate process. Sturgeon have no bones, just cartilage. If handled too rough the spinal cord can be damaged

Harvesting the caviar kills the fish. The entire ovary is removed and carefully rubbed across a screen to separate the eggs from the membrane. The eggs are lightly salted and packed in jars or tins.

Caviar is ranked according to a hierarchy, with the eggs from three types of Caspian Sea sturgeon topping the list. The first, beluga caviar, is the rarest and the most expensive.
Next comes osetra caviar and then sevruga caviar. Caviar from sturgeon elsewhere in the world (including America) generally follows. Caviar from the white sturgeon is said to be most similar to osetra.
Initial tastes of our caviar have brought rave reviews, and because of the environmental control a farm offers Idaho caviar may someday compete with beluga.

Our alligators are raised and processed in Idaho under our daily supervision. The meat is processed in our processing plant to our strict standards.
Gator meat is an excellent choice for health-conscious consumers. It is high in protein and very low in calories, fat, saturated fat and cholesterol.
