Nabereznaya 18, 683600, Petropavlovsk-Kamchatskii, Russia aut The effect of the infectious hematopoietic necrosis virus on the population of sockeye salmon Oncorhynchus nerka (Salmoniformes, Salmonidae) from Lake Nachikinskoe [Elektronische Daten] [S. Rudakova] The results of virological examination of adult sockeye salmon Oncorhynchus nerka in Lake Nachikinskoe from 2003 to 2008 demonstrated high values of prevalence of the infectious hematopoietic necrosis virus (IHNV) in the fish population (up to 100%). In the studied water reservoir there are optimal conditions for the development and revealing of the epizootic of infectious hematopoietic necrosis (IHN). In Lake Nachikinskoe, two natural epizootics of IHN in juvenile sockeye salmon were recorded in 2003 and 2006. The tendencies for change of prevalence of IHNV by years were analyzed, and their relation to the numbers of adult sockeye salmon at the spawning grounds of Lake Nachikinskoe was determined. The correlation of IHNV prevalence with the numbers of adult sockeye salmon in the studied water reservoir is direct but insignificant (r s = 0.695, p < 0.05). It was shown that the epizootic of 2003 could affect the fact that fish return in 2007 and 2008 was minimum for the considered time interval while the numbers of their parents were, on the other hand, very high.
