Abstract Excerpt:
Sockeye salmon are characterized by extremely complex population structure: populations reproducing in different river watersheds (metapopulations) are subdivided into seasonal races, ecotypes, and subpopulations of isolated spawning grounds. Because of the genetic and morphological differentiation of the intraspecific forms, samples collected in the downstream reach of a river are normally heterogeneous. This includes both mixed samples from an estuary and samples collected during sockeye salmon spawning run in lower river flow. The objective of the paper was to analyze subdivision of sockeye salmon samples from the low course of East and West Kamchatka rivers, where (in tributaries and lakes) the most commercially important Asian stocks are reproduced.
