Bijia Fish Maw is produced in Shishou City, Hubei Province. The Yangtze River winds from west to East, reaching the Shishou river section of the Yangtze River. Shishou Bijia Mountain stands next to the river, blocking the flow of water to the East. The rapid return flow becomes a paradise for the longirostris.

Bijia Fish Maw is made from the swimming bladder of the longirostris in the Shishou river section of the Yangtze River Basin. After killing the fresh longirostris, take out the white, transparent, flexible and moderate swimming bladder, with the specification of no less than 100g. It is made by soaking, cleaning, low-temperature energy-saving cold air drying, vacuum expansion and other processes.

The shape of Bijia Fish Maw is like the penholder, with the characteristics of big fat swimming bladder, thick glue layer, transparent and white jade like color, no blood silk residue and no scar nor injury. It has tender and fat texture and soft and sweet taste. The protein content is more than 60%. (Courtesy of the IP Protection Department of CNIPA)
