The lake features a unique ecosystem with a high degree of salinity, supporting significant populations of sturgeon that are central to the region's beluga caviar industry. Its geopolitical status has been a subject of ongoing international negotiation among the bordering countries to determine maritime boundaries and resource extraction rights.
