“…Our data generally concur with the findings of the earlier mentioned studies and others (e.g., Ruttenberg et al 2005), with elevated elemental concentrations in the calcified structures of the youngest life stages (but see Elsdon & Gillanders 2005), though we did not find ontogenetic shifts for the same particular subset of elements. For example, unlike Chittaro et al (2006), who found ontogenetic shifts in Ba, Pb, and Ce uptake, we did not find such shifts for the same suite of elements. Of course, the same mechanism may not be generating the ontogenetic shifts in differing taxonomic groups.…”

“…Fowler et al (1995) generated the first solid evidence for ontogenetic shifts in Sr and Ba uptake into fish otoliths by raising fish under completely controlled laboratory conditions. Most other evidence has been correlative or has been generated under partially controlled conditions only (e.g., Chittaro et al 2006, Otake et al 1997, Carriker et al 1996, Brophy et al 2004.

“…One possibility for eliminating the wastage involved with cracking open multiple oysters would be if recent settler or adult oyster shells could be sampled as a proxy tag of that of the brooded larva. That would require no ontogenetic shifts in element uptake into shells, however it has been known for decades that ontogenetic variation in bivalve shells might be problematic (Rosenberg 1980), and there is building evidence from field in situ studies of fish otoliths that ontogenetic shifts in element uptake do occur (e.g., Chittaro et al 2006), ruling out the possibility for using later stage calcified structures as proxies for larval structures (also see Ruttenberg et al 2005).…”

Despite the interest in restoring remnant populations of the Olympia oyster, Ostrea lurida Carpenter 1864, † little is known about connectivity among populations. Identifying the sources of settling larvae could broaden our understanding of the degree to which particular populations are reliant on their neighbors for their persistence. Calcified structures such as the otoliths of fish and statoliths of invertebrates are increasingly being exploited as useful ''natural tags'' that help track individual movements and, when applicable to larvae, could help to pinpoint important source populations. In controlled laboratory culturing experiments, we explored the prospects for using the chemistry of larval shells (prodissoconchs) as natural tags of larval source by examining whether larval shells record shifts in seawater element chemistry, whether larval shells undergo ontogenetic shifts in element uptake, and whether the chemistry of the shell formed during brooding is compromised by subsequent shell thickening during the planktonic phase. Results from a two-way ANOVA examining the effect of seawater element concentration and ontogeny showed that element/ Ca in the shell increased in response to increasing seawater elemental concentrations for Ba, Ce, Pb, and Mn, whereas shell Cu/Ca did not change. Ostrea lurida shell chemistry also showed strong ontogenetic shifts in element/Ca for Mg, Sr, and Cu during the transition from larva to settler. Settler shell Mg/Ca strongly increased compared with planktonic shell, whereas Sr/Ca and Cu/Ca showed the opposite pattern. Further, the chemistry of the shell formed during brooding (at the birth location) did change as a function of environmental conditions experienced during the planktonic phase for the elements Ba and Ce, but that change was limited to regions of the brooded shell just adjacent to the planktonic shell. When the brooded portions of larval shells were sampled closer to the umbo, the brooded shellsÕ chemistry remains intact. The combined results suggest that larval Ostrea lurida shells act as recorders of environmental change and show promise as tools to track larval movements.

“…Another potential limitation of our classifier was the differences in age among the fish from each lagoon, because several elements can vary in otoliths as a function of life stage (Chittaro et al 2006). Variation in otolith signature depends on the number of individuals, sites, and seasons analyzed in each habitat.…”

Precise knowledge of lifetime migrations is vital in exploited fish species, since all essential habitats must be protected to maintain sustainable stock levels. The present study used multi-element otolith fingerprints of the gilthead sea bream Sparus aurata (L.) to discriminate its main juvenile and adult habitats in the Languedoc-Roussillon region (Gulf of Lions, northwest Mediterranean) and infer the lifetime migrations of 12 individuals from the area (11 from the present day and 1 from the Roman era). This allowed for the first time the identification of key habitats for the successful completion of the species' life cycle in the Gulf of Lions, and the connectivity between them. Our results revealed that lagoon use by S. aurata is probably ancient (> 2500 yr) and confirmed its current commonness. Yet, although most observed migration patterns were in accordance with the migratory behavior previously described for the species, strong inter-individual variations and new patterns in habitat use were detected. At the juvenile stage, a preference for shallow lagoons with low salinities was evidenced. Nevertheless, the first year of life can also be successfully completed in marine conditions. At the adult stage, lagoon use was shown to occur until at least age 4 yr, with periods of lagoon residency of up to 11 mo in a year, often including winter months. Because overwintering in the lagoons was previously thought to be impossible for S. aurata due to low temperatures, this finding has important implications for future stock management, especially since the species breeds in winter.

“…In addition to environmental factors such as temperature, salinity and elemental compositions, factors such as ontogenic and physiological effects have also been found to influence otolith elemental compositions in some species of fish (Kalish 1989, Otake et al 1994, Chittaro et al 2006. In the present study, we minimized the ontogenetic effects on the otolith chemistry by using fishes of particular year classes to examine the geographic variations among sampling groups.…”

In order to examine whether otolith elemental composition of Pacific herring Clupea pallasii reflected spatially specific differences in capture location, we analyzed the elemental compositions in the edge portion of each otolith, which corresponded to the period immediately prior to the capture, as an indicator of the geographic areas in which the outer otolith was deposited. We collected 7 fish groups from 5 coastal sites: Tomamae offshore, Ishikari Bay, Akkeshi Bay, Lake Furen and Miyako Bay along the Japanese coast. Six elemental ratios, Na/Ca, Mg/Ca, K/Ca, Cu/Ca, Sr/Ca and Ba/Ca, were measured in the edge areas of each otolith by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Significant differences were shown in all mean elemental ratios of otoliths among 4 sampling groups in the 2005 year class and among 3 sampling groups in the 2006 year class. The classification accuracy with the jackknife cross-validation using quadratic discriminant function analysis ranged from 80 to 98% and 78 to 100% in the 2005 and 2006 year classes, respectively. Our findings are comparable to those in previous studies and are further evidence that otolith chemistry is a potential tool for identifying the Pacific herring groups with different habitatuse histories and migration patterns.

In order to understand the population dynamics of Pacific herring, it is important to discriminate each ecologically different population and to determine the migration patterns for feeding and spawning in coastal and oceanic habitats.In previous studies, the population structure and the movements of Pacific herring were examined using artificial tags and genetics (Grant & Utter 1984, Kobayashi et al. 1990, Hay et al. 2001, Sugaya et al. 2008. Artificial tagging methods however, can only link a recaptured fish to the geographic area where it was marked. Furthermore, they are impractical for smallsize fishes because of the high rates of mortality during early life stages, and because of the requirement of a large number of tagged individuals to ensure a sufficient number of recaptures. Genetic composition can link fish to their origin populations, but not to the geographic areas where it was distributed. In Pacific herring, therefore, alternative approaches are required for studying the population structure and the movements of individual fish.To date, the chemical compositions of otoliths of teleost fishes have been analyzed to elucidate ecological questions concerning their population structure (Campana et al. 1994, Milton et al. 1997, population connectivity (Gillanders 2002), migration (Limburg 1995, Arai et al. 2004, th...
