On April 27, 2022, while surveying the coast of the Caspian Sea, employees from the Fish Inspectorate for the Mangistau Region of the MEGNR Fisheries Committee, the Department of Ecology for the Mangistau Region, the veterinary service and local executive bodies found 94 dead Caspian seals. Representatives of the Department of Ecology for the Mangistau Region took water and soil samples for laboratory research.
