Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The Aral Sea was one of the main commercial basins until the 80s of the last century. However, intensive water management activities aimed at regulating the upper reaches of the Syrdarya and Amudarya rivers, which were the main sources of water supply in the Aral Sea, led to a decrease in the water level and the sea was initially divided into two reservoirs: Small and Large. As a result, huge damage was caused to the fishing industry of the region. And only after more than 20 years, a decision was made to restore the Aral Sea, by building a dam, in order to block the channel connecting the Small Aral with the Big Sea. In 2005, the construction of the Kokaral separation dam was completed. The basis of the fishery is: bream (Abramis brama), zander (Sander lucioperca), pike (Esox lucius), asp (Aspius aspius), carp (Cуprinus caspio)
