The otolith strontium (Sr):calcium (Ca) ratios have been widely used to reconstruct the migratory history of anguillid eels. However, factors affecting the Sr:Ca ratios in otoliths are incompletely understood in tropical anguillid species. To determine the salinity effect on the otolith Sr:Ca ratios, the Sr and Ca contents of otoliths of the giant mottled eel, Anguilla marmorata, reared for 60 days...
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...
