Turkmeniski Bay is considered one of the most important places where these species of fish grow. The industrial complex for the artificial cultivation and production of sturgeon was built in Gyyanly, in Balkan Province. These pollutants originate primarily from sewage, agricultural run-off and oil-related activities, and are transported by rivers and discharged into the Caspian Sea. The area of greatest offshore development in Turkmen waters is near Turkmenbashy, Cheleken and Ogutchisky Island.
