RÉSUMÉ

The mass fish kill, vendace chiefly, was observed in Lake Lekshmozero (the Arkhangelsk oblast [administrative division], the Russian Federation) in 1996. Thirty-five tons have been buried. The fish kill phenomenon is extremely rare under conditions of the north (the Arkhangelsk oblast and Karelia). Ecological conditions in the lake, which could lead to fish death, and the state of the lakes ecosystem during the modern period are discussed.
