Salinities, not diets, affect strontium/calcium ratios in otoliths of Anguilla japonica
Although otolith Strontium (Sr)/calcium (Ca) ratios have been widely used to reconstruct the past salinity environmental history of anguillid eels, factors affecting the Sr/Ca ratios in otoliths are incompletely understood. Japanese Eel (Anguilla japonica) elvers (mean length 54.7±2.1 mm) were collected in the estuary during their upstream migration and reared at 5 different salinities (0, 5, 1...
متن کاملRelationship of otolith strontium-to-calcium ratios and salinity: experimental validation for juvenile salmonids
Analysis of otolith strontium (Sr) or strontium-to-calcium (Sr:Ca) ratios provides a powerful tool to reconstruct the chronology of migration among salinity environments for diadromous salmonids. Although use of this method has been validated by examination of known individuals and translocation experiments, it has never been validated under controlled experimental conditions. In this study, in...
متن کاملStable isotope (δ13C and δ18O) and Sr/Ca composition of otoliths as proxies for environmental salinity experienced by an estuarine fish
The ability to identify past patterns of salinity habitat use in coastal fishes is viewed as a critical development in evaluating nursery habitats and their role in population dynamics. The utility of otolith tracers (δ13C, δ18O, and Sr/Ca) as proxies for environmental salinity was tested for the estuarine-dependent juvenile white perch Morone americana. Analysis of water samples revealed a pos...
متن کاملMisidentification of the migratory history of anguillid eels by Sr/Ca ratios of vaterite otoliths
Most fish otoliths are composed of aragonite, but occasionally they form a mosaic with its polymorph, vaterite. We found an unusual mosaic structure of extremely low strontium to calcium (Sr/Ca) ratio in the aragonite otoliths of European eels Anguilla anguilla. The mosaic crystal structure in the eel otolith appeared opaque under reflected light after EDTA etching and was confirmed to be a vat...
متن کاملUsing Otolith Chemistry Tags and Growth Patterns to Distinguish Movements and Provenance of Native Fish in the Grand Canyon
Fish otolith and water chemistry were assessed in the Grand Canyon reach of the Colorado River and its tributaries. Aqueous strontium and selenium (in ratio to calcium) and carbon stable isotopic ratios were identified as markers with excellent potential to track the provenance and movements of the endangered humpback chub Gila cypha. Although otolith dC and Sr/Ca varied proportionately to wate...
