Fisheries research in Yamal

Specialists of the Tyumen branch of the Scientific Research Center of the Russian Federation "All-Russian Research Institute of Fisheries and Oceanography" (VNIRO) conducted large-scale research in the Yuribey River basin in Yamal as part of the state monitoring of aquatic biological resources.
 
During the expedition, scientists studied the ichthyofauna of the region in detail: they performed more than 220 biological analyses and 1,700 mass measurements of whitefish — grouse, whitefish, pelyadi, muksun and other species, and also selected age‑recording structures. All the data obtained were carefully recorded in field ichthyological journals and scale books.
 
An equally important area of work was the analysis of the habitat and food supply of fish: experts took samples of zoobenthos, phyto‑ and zooplankton. After processing the collected material, scientists will determine the size and age of the populations, calculate the number and biomass of fish.
 
The results obtained will form the basis for catch forecasts for the coming years and will help ensure the rational use of the region's fish stocks.
