The collective monograph "Krillon Peninsula: History and Modernity on the Shores of Aniva Bay" was published. One of the chapters "Sakhalin taimen on the territory of the Krillon Peninsula" was written by S. S. Makeev. It tells, among other things, about a new method of contactless monitoring of numbers - using an underwater camera in wintering pits. Preliminary estimates of the populations of the Moguchi and Ulyanovka rivers are given.
