“…In addition, sagittal otoliths were collected from a masu salmon and a white spotted char in the Koppi River. The masu salmon and white spotted char were presumed to have migrated to sea (Arai and Tsukamoto 1998;Arai and Morita 2005) and were included for comparison with putative migratory fish. The otoliths from Koppi and Tumnin River fishes were obtained through a joint research project involving the Wild Salmon Center and the Khabarovsk TINRO during 2000-2002.…”

Sakhalin taimen (Parahucho perryi) range from the Russian Far East mainland along the Sea of Japan coast, and Sakhalin, Kuril, and Hokkaido Islands and are considered to primarily be an anadromous species. We used otolith strontium-tocalcium ratios (Sr/Ca) to determine the chronology of migration between freshwater and saltwater and identify migratory contingents of taimen collected from the Koppi River, Russia. In addition, we examined taimen from the Sarufutsu River, Japan and Tumnin River, Russia that were captured in marine waters. Transects of otolith Sr/Ca for the Sarufutsu River fish were consistent with patterns observed in anadromous salmonids. Two fish from the Tumnin River appeared to be recent migrants to saltwater and one fish was characterized by an otolith Sr/Ca transect consistent with marine migration. Using these transects as benchmarks, all Koppi River taimen were classified as freshwater residents. These findings suggest more work is needed to assess life history variability among locations and the role of freshwater productivity in controlling migratory behavior in taimen.

“…Thus, the migratory histories of individual specimens can be revealed by observing the Sr:Ca (calcium) ratios of otoliths (Arai 2002). Using this method, the life histories and migrations of many salmonid species have been documented (Kalish 1990;Arai and Tsukamoto 1998;Volk et al 2000;Arai and Miyazaki 2002;Arai and Morita 2005;Brenkman et al 2007). Arai et al (2004) analyzed the microchemicals in otoliths of H. perryi in Lake Aynskoye (which is not influenced by the rising tide due to the occurrence of an intermittent river with 0 psu), Sakhalin Island, Russia, and revealed the existence of anadromous fish.…”

Life history and migration of Sakhalin taimen, Hucho perryi, caught from Lake Akkeshi in eastern Hokkaido, Japan, as revealed by Sr:Ca ratios of otoliths

et al. 2010

Microchemical analysis of the strontium (Sr) and calcium (Ca) ratios of otoliths was conducted to determine the life history and migration of anadromous Sakhalin taimen, Hucho perryi. In 2008 and 2009, 10 specimens were sampled from Lake Akkeshi in eastern Hokkaido, Japan. Our results indicated that some specimens migrated to brackish waters during their early life history. Because the Sr:Ca ratios of the specimens in this study were all less than those of specimens from Sakhalin Island during a previous study, specimens of Lake Akkeshi may have migrated to brackish water, or remained in the ocean for only a short period

“…The Sr concentration in seawater is approximately 100-fold higher than that in freshwater [1], and thus Sr appears to be a good tracer of the environmental conditions encountered, notably salinity variation under either natural or controlled conditions. In the Salmonidae family, otolith Sr or Sr:Ca ratio analyses have been widely used to reconstruct the environmental history due to the occurrence of anadromy [3][4][5][6][7][8][9].…”

In order to determine the salinity effect on otolith strontium (Sr):calcium (Ca) ratios, the Sr and Ca contents of otoliths of Sakhalin taimen, Hucho perryi, reared for 60 days in four salinities (freshwater, one-third seawater, two-thirds seawater, and full seawater) were examined. The Ca and Sr contents and the resultant Sr:Ca ratios in the rearing water increased linearly with salinity. Otolith Sr:Ca ratios were also found to be positively correlated with salinity. However, the Sr:Ca did not correspond to temperature fluctuations during the experiment. These results indicate that Sr:Ca ratios in otoliths can be used to reconstruct the migratory history of the fish by differentiating when the fish migrated between freshwater and seawater.
