“…These studies consistently show that an increase in ambient concentration results in a significant increase in Sr concentration within calcified structures. For fish, this result is consistent between freshwater (see Mugiya et al 1991) and saltwater species (see Bath et al 2000). Comparisons of data from the literature with the results of the current experiment are difficult, given that different sampling techniques can affect the detected concentrations of elements when organisms, such as fish, have been reared for short periods of time (Elsdon & Gillanders 2003a).…”

Chemical elements within calcified structures of organisms such as fish, corals, bivalves, gastropods and foraminiferal shells can provide a record of the environmental characteristics at the time of calcification. To predict accurately the environmental characteristics at the time of calcification, it is important to understand the influence of exposure time on elemental incorporation. We examined the effect of enhanced ambient strontium:calcium (Sr:Ca) (2 × and 4 × ambient concentrations) and different periods of exposure (2, 4, 8, 16 and 32 d) on Sr:Ca uptake and incorporation into fish otoliths of the black bream Acanthopagrus butcheri (family: Sparidae). Sr:Ca ratios (hereafter referred to as concentrations) in bream otoliths increased with increasing ambient concentrations, with the amount of Sr:Ca incorporated into otoliths being positively affected by the period of exposure. Saturation of Sr:Ca in otoliths occurred after 20 d of exposure. Importantly, by measuring multiple variables of elemental uptake and incorporation, the relative effect of enhanced concentration and exposure time can be separated, which to date has not been possible. This research will allow for greater accuracy when interpreting environmental histories of fish.

Consequently, the rate at which elements are incorporated into calcified structures would affect the interpretation of environmental histories, both spatially and temporally.The time required for elements to be incorporated into calcified structures is largely unknown, although there have been several attempts to examine the effect of exposure time to enhanced elemental concentrations on the uptake and incorporation of elements in fish otoliths, spines and vertebrae (Snyder et al. 1992, Ennevor & Beames 1993, Brown & Harris 1995, Pollard et al. 1999). Due to technical constraints, all of these experiments analysed whole calcified structures using solution-based techniques (e.g. whole otolith), and, in doing so, the derived elemental signatures were a mixture over the entire chronology of the structure. As reconstructions of environmental histories require high resolution of elemental concentrations, sample analysis requires the use of fine-scale micromilling or laser instruments (Elsdon & Gillanders 2003a). Nevertheless, experiments using solution-based techniques have shown that an increased period of exposure to environmental variables results in enhanced concentrations of elements being incorporated into calcified structures of fish (e.g. Pollard et al. 1999). Further experiments using more modern sample analysis are needed to assess the effects of exposure time on elemental incorporation; these experiments will provide more ...

“…Other elements such as Li, Sr and Ba are likely to reflect physico-chemical conditions (Elsdon & Gillanders 2003, Hicks et al 2010, although the Sr:Ca ratio may also be related to growth rate (Sadovy & Severin 1992. Mn is consistently elevated in otolith cores (Brophy et al 2004, Ruttenberg et al 2005, suggesting that in the natal and larval life history stages the Mn:Ca ratio is not related to environmental conditions or ambient concentrations (Bath et al 2000, Elsdon & Gillanders 2003, Miller 2009) but may be influenced by diet (Pentreath 1976, Mugiya et al 1991, Sanchez-Jerez et al 2002. However, in juvenile otoliths, Mn:Ca ratios may be affected by sediment type (Fodrie & Herzka 2008) and by temperature in adults (S. E. Swearer unpubl.…”

“…More than 30 different elements have been detected in fish otoliths (Campana 1999). Since otoliths are physiologically inert, it is widely accepted that their chemical composition remains unchanged over time, thus providing a permanent record of the historical environmental conditions experienced by the fish (Mugiya et al 1991;Dove and Kingsford 1998;Campana and Thorrold 2001;Fowler et al 2005). …”

Fish otoliths are a reliable source of historical data regarding individual fish. Optical and chemical data obtained from otoliths are used to reveal the fish's age, natal areas, dispersal trajectories, and more. However, whereas optical methods are well established and widely practiced, methods for obtaining and interpreting chemical data continue to evolve. Despite rapid advances in the past decade, analytical approaches to otolith microchemisty continue to develop as new opportunities and limitations emerge. Otolith chemistry often reflects environmental conditions such as the chemical composition, temperature, and salinity of the ambient water. However, it is not always clear how these interact to produce the chemical signature observed in the otolith. Such gaps and inconsistencies in our knowledge may result partly from valuable information being discarded when measured concentrations fall below customarily defined detection limits (DL). Below we review some of the inaccuracies that may arise when analyzing chemical data obtained from laser-ablation inductively coupled mass spectrometry (LA-ICPMS). We argue that measurements traditionally defined as sub-DL can contain valuable information that would otherwise be discarded. We base our argument on the analysis of sub-DL signals obtained from both sides of otoliths core. Specifically, we show that these signals often form sequences that are symmetrical about the core (palindrome), and that the probability of obtaining even the simplest palindromic sequence by chance falls well below the customary 5% significance level. We conclude by discussing how this microchemical data can be analyzed in a manner that is insensitive to errors in concentration readings.
