The concentration of phosphorus in Lake Sevan is increasing, as Environment Minister Erik Grigoryan said at the press conference held on the World Environment Day. Phosphorus is one of the pollutants promoting lake waterlogging. “Phosphorus concentration in Lake Sevan is increasing because of several springs, including “Sevan Trout”. A German institution has carried out research which showed that the concentrations of phosphorus in the area of cage nets of “Sevan Trout” are higher than in other areas,” Erik Grigoryan said, “If specialists consider the phosphorus concentrations generating from the cage net economy problematic, then a decision will be reached to remove them".

Reminder: at the trial of the case “On Hazards Threatening Lake Sevan Having Strategic Significance for Armenia” held on 8 May, Director of the Foundation for Recovery of Sevan Trout Reserves and Development of Fish Breeding Vardan Mamikonyan said currently the production doesn’t exceed 150 tons. In 2013-2017 the Foundation for Recovery of Sevan Trout Reserves and Development of Fish Breeding received 9 billion AMD from the state for the implementation of this project. 

Lake Sevan gets polluted with phosphorus because of restaurants, sewage water from urban and rural residential areas and agriculture. Around 2400 legal and illegal public food objects are operating on the lake shore, out of which 300 permanents ones don’t have cleaning stations.

According to the data by Lake Sevan Preservation Expert Committee, mechanical cleaning stations constructed in the towns of Lake Sevan basin don’t work with full load because of the absence of sewage network - 60% in Gavar, 35% in Martuni and 20% in Vardenis.
