We examine 87Sr/86Sr isotope ratios in transects across the otoliths of the diadromous tropical shad hilsa, Tenualosa toli, to assess the extent of movement of fish within the large Meghna (Ganges) River system and adjacent coastal waters. Hilsa collected from marine, estuarine, and freshwater habitats were born in all main rivers in Bangladesh. All fish moved widely, entering water of marine 87Sr/86Sr isotope ratio by 1 year of age. Most returned to fresh water after they reached sexual maturity, but not necessarily to their natal region. Comparison of the 87Sr/86Sr isotope and Sr/Ca ratios of hilsa showed that in the Meghna River, 87Sr/86Sr isotope ratios can only distinguish fish from waters when the salinity was less than 5‰. Sr/Ca ratios were more useful for interpreting fish movements at higher salinities. To assess whether whole-otolith 87Sr/86Sr isotope ratios reflected the ratios of the water of natal origin, we compared the 87Sr/86Sr ratios of otolith cores with the mean 87Sr/86Sr isotope ratio of the whole transect. We found major differences between the two measurements, suggesting that 87Sr/86Sr isotope ratios from whole-otolith assays may not accurately reflect the natal origin of the fish.

AbstractThe 87Sr/86Sr isotope ratio can, in principle, be used for provenancing of cement. However, while commercial cements consist of multiple components, no detailed investigation into their individual 87Sr/86Sr isotope ratios or their influence on the integral 87Sr/86Sr isotope ratio of the resulting cement was conducted previously. Therefore, the present study aimed at determining and comparing the conventional 87Sr/86Sr isotope ratios of a diverse set of Portland cements and their corresponding Portland clinkers, the major component of these cements. Two approaches to remove the additives from the cements, i.e. to measure the conventional 87Sr/86Sr isotopic fingerprint of the clinker only, were tested, namely, treatment with a potassium hydroxide/sucrose solution and sieving on a 11-µm sieve. Dissolution in concentrated hydrochloric acid/nitric acid and in diluted nitric acid was employed to determine the 87Sr/86Sr isotope ratios of the cements and the individual clinkers. The aim was to find the most appropriate sample preparation procedure for cement provenancing, and the selection was realised by comparing the 87Sr/86Sr isotope ratios of differently treated cements with those of the corresponding clinkers. None of the methods to separate the clinkers from the cements proved to be satisfactory. However, it was found that the 87Sr/86Sr isotope ratios of clinker and cement generally corresponded, meaning that the latter can be used as a proxy for the clinker 87Sr/86Sr isotope ratio. Finally, the concentrated hydrochloric acid/nitric acid dissolution method was found to be the most suitable sample preparation method for the cements; it is thus recommended for 87Sr/86Sr isotope analyses for cement provenancing.
