High water quality and good food supply for commercial fish were noted.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. Scientists from the Krasnoyarsk Agrarian State University conducted a study of the Yenisey bay’s ichthyofauna. In fact, this is the first such study in the bay, which is of high significance for Taimyr.

The project was implemented with the help of the RN-Vankor company’s grant. During the research, 13 species of anadromous and semi-anadromous fish were discovered, as well as 18 species of marine fish that occur constantly or occasionally. The reservoirs in which the study was carried out turned out to be inhabited mainly by valuable species of fish of the whitefish family – gangfish, peled, vendace, muksun, tugun, whitefish and nelma.

Flounder and pink salmon also periodically penetrate into the mouth of the river from the Kara sea, and char, grayling, broad whitefish, whitefish, pike, and burbot from the tributaries flowing into the bay.

Almost all discovered fish species, with the exception of polar cod and slingshot, are of commercial importance, including for the indigenous peoples of the North. The most common fish species among them are whitefish and smelt.

Environmentalists noted that the fish go to the Kara sea to feed and spawn. There is shallow water there, which, when freed from ice, quickly warms up, and the water at different points has different salinity, creating favorable conditions for marine and freshwater fish. Experts noted the high quality of water in the Yenisey bay and a sufficient number of food organisms in its reservoirs.

The studies carried out, according to regional media reports, formed the basis for proposals for the introduction of environmental standards, the possibility of creating special areas for natural feeding and spawning of fish, and the fish farming development in Taimyr.

Earlier, we reported that in Russia they are going to breed Arctic char in captivity.
