Justification:
Until 1936 this species was extremely abundant. Catches of 300-620 tonnes per annum were reported. However, by the 1960s this had been reduced to 69 tonnes per year. The population decline was also aided by a gill sucker which infected this species. During the 1970s and 1980s the salinity levels in the Aral Sea rose sharply and this species disappeared. There have allegedly been reports of occasional catches of this species in the Uzbekistan part of the Aral Sea, but these have yet to be confirmed. These may be fish that have survived in the upper parts of the Amu Darya River in Turkmenistan and Tajikistan. This subpopulation, which is probably extremely small if not Extinct, is excluded from this assessment.
