Abstract

Temporal series of density in the spawners of two sockeye salmon populations from Azabach'e Lake (Kamchatka River basin) were analyzed using periodic functions. It has been found that the quality of describing the density dynamics for sockeye salmon by such models is very high (R 2= 0.943 and R 2= 0.905 for early and late populations, respectively). The density (for early sockeye salmon) and total number (for late sockeye salmon) distributions of the reproductive fraction of the populations have been developed and analyzed.
