a baiji conservation dolphinarium was established at the institute of hydrobiology (ihb) in wuhan in 1992. this was planned as a backup to any other conservation efforts by producing an area completely protected from any threats, and where the baiji could be easily observed. the site includes an indoor and outdoor holding pool, a water filtration system, food storage and preparation facilities, research labs and a small museum. the aim is to also generate income from tourism which can be put towards the baiji plight. the pools are not very large, only kidney shaped tanks with dimensions of arc width and depth, diameter, deep and diameter, deep, and are not capable of holding many baijis at one time.
