The sturgeons with roe, also known as Chinese sturgeons, were sent to Yichang as part of the comprehensive ecological compensation project of the "Yangtze River Hubei Yichang Chinese Sturgeon Nature Reserve" in the second half of 2022 to increase and release fish stocks. will be released into the Yangtze River. The Yangtze River sturgeon is a migratory fish. After being released into the Yangtze River, it will arrive in Wuhan in 5-7 days and arrive at the Yangtze Estuary in about 1 month. Then it will live in the ocean for 10-15 years, and then enter the Yangtze River from the Yangtze Estuary, all the way upstream. They migrate upstream to the spawning ground under Gezhouba Dam on the Yangtze River to lay eggs. In other words, the Chinese sturgeons released at this time are not expected to meet us again in the Yangtze River in 10 years.
