The fish, measuring 50 cm and weighing 10 kg, was identified by local experts and released back into the river. This is the first wild Chinese sturgeon sighting in the Ma'anshan section of the Yangtze River since a 10-year fishing ban was implemented, indicating improved water conditions for aquatic life.
