Amu Darya Shovelnose Sturgeons represented by two sturgeon species of the genus  Pseudoscaphirhynchus are among the most unusual and rarest fishes in the world inhabiting only the basin of Amu Darya River. Amu Darya Shovelnose Sturgeons are amazingly well fitted to live in rapid and muddy waters of Amu Darya. This fish is practically deprived of pigmentation which makes his coloration white, sometimes with yellowish or darkish shades; his eyes are small, almost reduced and he has huge olfactic cavities; Shovelnose Sturgeons are well protected from predators by very sharp spines forming a kind of saw-looking lump along the back; and finally the tail of Large Amu Darya Shovelnose Sturgeon ends with long cord containing multiple receptors which probably serve to select optimal position in strong streams. 

So far (by 2017) due to substantial difficulties experienced by our team in finding resources to finance  the activities intended to protect and preserve Amu Darya Shovelnose Sturgeons initial steps only have been taken to discover breeding sites of these species at least along the length of Amu Darya River within the inner territory of Uzbekistan (Khorezm province and Karakalpakstan) still accessible for investigators ( almost the whole remaining territory of Amu Darya River represents the border between Uzbekistan and Turkmenistan, Uzbekistan and Afganistan, Tadjikistan  and Afganistan and access to this area is problematic). However there are serious reasons to presume that the breeding sites of Amu Darya Shovelnose Sturgeons are substantially endangered. The situation is caused by ever changing hydrological regime of Amu Darya River, by large-scale water outlet to ensure irrigation of agricultural areas which existed inside the desert for a long time but which were considerably increased during the Soviet period. Amu Darya hydrological regime was also much affected in the course of construction of hydroelectric power stations and  dams which were undertaken during the Soviet and post-Soviet times and caused water stream velocity and level regulations (e.g. Vakhsh hydroelectric power chain, Tuyamuyun hydroelectric power station).  Similar situation can be observed in the basin of  Syr-Darya - another largest river of this region. Syr-Darya hydrological regime corrections and loss of breeding sites caused practical extinction of Syr-Darya Shovelnose Sturgeon (Pseudoscaphirhynchus fedtschenkoi) which is the closest relative of Amu Darya Shovelnose Sturgeons (this was confirmed by local fishermеn in the course of enquiry undertaken by Nikolai Muge, a member of the Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) and his Kazakh colleagues).

Poaching is another serious problem since Amu Darya Shovelnose Sturgeon (the local name is "bakra" or "bekre") in Khorezm Province and Karakalpakstan is regarded by local people as an effective cure for female infertility. This phenomenon is a result of peculiar transformation of ancient pre-Islamic beliefs of the Khorezmian people.

Amu Darya River is the home place for two species of Shovelnose Sturgeon, namely the Large Amu Darya Shovelnose Sturgeon (Pseudoscaphirhynchus kaufmanni) and especially rare Small Amu Darya Shovelnose Sturgeon (Pseudoscaphirhynchus hermanni). There are two forms of  Large Amu Darya Shovelnose Sturgeon and they are commonly named “big broadnose” and “small narrownose” because they distinguish by their size and form of  their head.

A group of Russian and Uzbek researchers striving to protect Amu Darya Shovelnose Sturgeons so that these species do not suffer the fate of their Syr-Darya relative are implementing the initiative  put forward by Alexei Chernyak, author of the www. life-on-earth.ru project and curator of the Eurasian Rarest Sturgeon Species Conservation Programme (promoted by the Eurasian Regional Association  of Zoos and Aquariums (EURAZA)).  During the last years this group in cooperation with the Khorezm Mamun Academy in Khiva (a branch of the Academy of Sciences of Uzbekistan) concentrated its scientific efforts on creation of a sustainable reserve group  of this fish. In December 2014 a  license was obtained for catching of the Large Amu Darya Shovelnose Sturgeon in the Khorezm province of Uzbekistan. This allowed to organize expedition to explore the Lower Amu Darya  (in the part located lower the Tuyamuyun hydroelectric power station) and discover localities where both forms of the Large Amu Darya Shovelnose Sturgeon and Small Amu Darya Shovelnose Sturgeon inhabit; as a result several specimens of mature (morphologically)  Large Amu Darya Shovelnose Sturgeon including one specimen of the “broadnose” and two specimens of the “narrownose” forms have been caught.  They are now kept in the pool installed in the Khorezm Mamun Academy premises.

Next step was to enlarge the Shovelnose Sturgeon reserve group  and ensure of their reproduction in pool conditions.

In 2015 another license was obtained for catching of  the both species of Amu Darya Shovelnose Sturgeon. In November  2015 – January 2016 new expedition to Khorezm province of Uzbekistan was arranged by our group to assist the Khorezm Mamun Academy to enlarge the Shovelnose Sturgeon reserve group and create small pool complex in the Khorezm Mamun Academy premises. At the end of our expedition both species of Amu Darya Shovelnose Sturgeon had been catched and it became possible to study both forms of  the Large Amu Darya Shovelnose Sturgeon (“big broadnose” and “small narrownose” forms) and Small Amu Darya Shovelnose Sturgeon in one pool.

In April 2016 and April 2017 experimental researches were carried by our group in cooperation with the Russian Federal Research Institute of Fresh Water Fisheries (VNIIPRH) and Aleksin Sturgeon Fishery (Tula Region of Russia) to determine sex and maturity of Amu Darya Shovelnose Sturgeons living in the small pool complex of the Khorezm Mamun Academy in Khiva; for this purpose various methods were used including ultrasound scanning. This research work received support from the World Wildlife Fund (WWF) Russia.

The ultrasound scanning was carried by Alexey Myshkin assisted by Dmitry Balashov (the Russian Federal Research Institute of Fresh Water Fisheries (VNIIPRH), with participation of Zokir Radjabov (Khorezm Mamun Academy).

 

 

In June-July 2017 the project www.life-on-earth.ru supported by WWF Russia carried preliminary research in the feeding areas and estimated breeding sites of the Amu Darya Shovelnose Sturgeons in the Lower Amu Darya  (in the part located lower the Tuyamuyun hydroelectric power station) between Pitnak and Kipchak towns.
