«Stomachs of most of the fish studied (nearly 90%) were absolutely empty, the fish just did not eat anything. The reasons for this are being studied now,» Nikolai Moshkin, a scientist member of the expedition, is quoted by the press service as saying.

He explained that the scientists selected samples of plankton and benthos (organisms living in the river bottom) at four locations in order to study the food base of the fish. Now the scientists expect that the results would help come to a conclusion whether the quality of the forage reserve and the population of several fish species have declined. Among these fish species are Stenodus nelma (aka sheefish or inconnu), broad whitefish, muksun, Coregonus sardinella (aka sardine cisco or least cisco), Coregonus vandesius, peled (aka northern whitefish), pike, burbot, Arctic grayling, and also pink salmon (aka hunmpback salmon), but the scientists have not been able to detect the presence of the latter in the reservoir.
