Unselective fishing methods including the use of rolling hooks, electrofishing gear and gillnets have had direct and dire consequences for the baiji as well. , 2007). , 2006). , 2000). , 2007). Anecdotal evidence suggests that at least one baiji was still alive in 2007, but more than likely, this species is either extinct or soon to be extinct. The IUCN has listed the baiji as critically endangered. Wang and Zhao‘s chapter 19 as well as Turvey‘s chapter 20 discusses the development of conservation measures and failed attempts to save the baiji from extinction.
