00:00Is it possible to obtain caviar without killing the sturgeon?
00:03For centuries, obtaining caviar meant the animal had to be sacrificed.
00:06The problem is that sturgeon takes up to 20 years to mature and produce roe.
00:10Killing the fish meant waiting another two decades for the next batch.
00:13This practice was so unsustainable that it nearly drove the species to extinction.
00:17Then, scientists found a solution.
00:19Today, they use ultrasound scans to detect when the rodent is ready.
00:22They then extract it via abdominal massage or a small incision.
00:25The animal survives and can produce caviar multiple times.
