The 10th International Symposium on Sturgeon (ISS10)

Yangtze Sturgeon (Acipenser dabryanus) is an endemic species to China. Influenced by human activities such as pollution, dam constructions and overfishing, its natural population in the wild has disappeared. It was listed as the first order category of the protected animals in China, and was proclaimed to extinct in the wild in 2022 by IUCN. To protect this species, 60055 propagated juveniles and adults were released in the middle Yangtze River between Yichang and Wuhan section since 2012. According to the data of fishery surveys from 2012 to 2023 in the middle Yangtze River and accidental capture data, 50 individuals with total length of 20-100 cm were recaptured in the trunk section from Yichang to Huanggang, and one was recaptured in the south Dongting Lake. The body length of recaptured individuals ranged from 47 to 103 cm, and the body tights ranged from 520 to 6500 g. Based on the survey results, increasing of number of released Acipenser dabryanus and carrying out of effective tracking and survey in the middle Yangtze River was suggesting.
