Biologist Robinson Orozco uses sonographic equipment to determine the sex of a small beluga sturgeon at Sturgeon Aquafarms in Bascom, Florida February 8, 2013. Sturgeon have to reach sexual maturity before they can produce roe. In the wild, that can take 15 to 20 years. But in captivity, with the right water temperatures and a specially formulated high-protein diet, it can happen in as little as six or seven years. Picture taken February 8, 2013.
