Found in the middle and lower reaches of the river. Feeds on a large variety of fish species (Ref. 1394). Major threats to baiji dolphins includes fisheries, degradation of habitats, river traffic, water pollution (Ref. 85335, 85336), and rolling hooks known to snag and drown baiji (Ref. 85336). In 1997 a comprehensive survey was able to document 13 individuals giving the experts an estimate of a population composed of less than 100 individuals (Ref. 85336).
