[99] [100] Surveys conducted between 2006 and 2008 by ichthyologists failed to catch any, but two probable specimens were recorded with hydroacoustic signals. [101] The last definite record was an individual that was accidentally captured near Yibin in 2003 and released after having been radio tagged. [96]
