North Aral Sea levels further were due to begin in 2010. The Aral Sea began shrinking in the 1960s, when the Soviet Union decided that the two rivers feeding it, the Amu Darya and the Syr Darya, would be diverted to irrigate cotton and food crops in Kazakhstan and Uzbekistan. In 1986, due to an accelerated loss of water, the Aral Sea split into northern and southern parts; the southern part is the current South Aral Sea. There is now an ongoing effort in Kazakhstan to save and replenish the North Aral Sea. As part of this effort, a dam project was completed
Torrentfish to feed. Torrentfish are solitary and benthic, but may be found in high densities where there is a large population. Because part of their life cycle is spent in the sea, they are found in higher numbers near the coast. Torrentfish are mainly found in gravelly rivers, particularly braided rivers with wide, open channels. They favour rivers with highly unstable substrates, as the regular movement of the gravels maintains open gaps around and underneath the stones where the torrentfish can take refuge from fast water. Although they are strong swimmers, they are poor climbers and are only found far inland
