Fish return to Tyumen rivers.
Small fish - crucian carp, eider, pike, perch - in the rivers of the Tyumen region are recovering after a mass death during the summer flood. As reported by URA. RU in the Nizhnevsk Department of the Federal Agency for Fisheries, water inhabitants are already returning to reservoirs against the background of water saturated with oxygen.
According to the department, populations will recover due to fish that survived in the upper part of rivers and tributaries that were not affected by the dead zone, as well as due to migration of fish to tributaries with favorable oxygen conditions.
But valuable species - salmon and sturgeon - will need help: to restore them, the fry must be released.
