Caviar is the word reserved exclusively for describing the roe (eggs) which come from the Sturgeon species. Since ancient times, caviar has been considered an ultra-luxury indulgence once reserved for Kings and Emperors. In modern times, it is still one of the most expensive and rare luxury products on the market. The finest caviar can fetch as high as US$10,000 per kilogram.
With the declining production of caviar from wild sturgeon, and the rapid increase in the quantity of caviar from farmed sturgeons to replace and protect the wild sturgeon, it is believed that there will be a considerable caviar market, and farmed caviar will replace the wild one in the future. In the foreseeable future, there may be very little wild sturgeon products on the world market, therefore, aquaculture production will be the major contributor to the caviar trade.
The cultured sturgeons have not only been used as food for human consumption, but also developed to derive cosmetic products, medical products, leather and other uses. In this regard, it is believed that diversification of products will increase in the future, serving more than one market and contribute to the sustainability of the industry.
