In the city of Nanjing, East China's Jiangsu province, 300 captive-bred Chinese sturgeon, along with other rare fish, were released into the longest river in the country.
It marked the first time the first-class state-protected animal had been released in the Nanjing section of the Yangtze River. Some 4,000 mullets, a species under second-class state protection, were released at the same time. |

The released sturgeon, which were raised through artificial breeding, are generally 15 months old and measure between 50 cm to 80 cm. Each of these sturgeon is implanted with a harmless transponder to track their whereabouts in the event they are unintentionally caught. |
