| Summary | Status: Endangered (Category I), in 1935-1937 about 10 specimens were caught every year; since then there have been no records of catching the Aral Lake trout. However, in the upper Amu Darya River, some specimens of this fish were caught until 1961. A special search for the Aral Lake trout has not been carried out. At one time this handsome trout, which reached 100 cm in length and weighed 13,5 kg, was the easternmost form of the anadromous kumzha. It inhabited the Aral Sea and the Amu Darya River Basin. Spawning areas of the Aral Lake trout in the upper Amu Darya River were identical to those of its freshwater form, the Amu Darya River trout (S. t. axianus). Therefore, the two forms might have come into contact during reproduction. Restoration of the Aral Lake trout could take place by transplanting of the Amu Darya River trout. It is necessary to prohibit catching of the Amu Darya River trout since it is potential source for restoration of the anadromous of the lake trout in this basin. |
