Popis: | Otolith Sr:Ca ratios of 11 masu salmon (Oncorhynchus masou) in Lake Kussharo and its tributaries, of which outlet river has no barriers to the ocean, were analyzed to estimate their migration histories. The Sr:Ca ratios of all masu salmon generally fluctuated below 2. Masu salmon from Lake Kussharo presumably do not migrate to the ocean. However, more specimens must be analyzed to clarify the migration history of masu salmon in this lake. |
