Section outline

    • The aquaculture of sturgeons, which produces high-quality caviar, is expected to be highly profitable. However, most of the fish body (called byproducts) after caviar processing is discarded and is very wasteful as only a small part of the meat is used. Thus, it is important to develop uses of the byproducts by reducing the parts to be discarded (zero emission).


      Collagen is extracted from byproducts to generate materials for tissue engineering, health foods，and cosmetics. The amount obtained varies greatly depending on the body part and extraction method.
