“…The major disadvantage is associated with the inability to take advantage of the chronological growth sequence recorded in the otolith. Atomic absorption spectrometry (AAS) (Grady et al 1989, inductively coupled plasma atomic emission spectroscopy (ICP-AES) (Edmonds et al 1995), neutron activation analysis (Papadopoulou et al 1980), Raman spectroscopy (Gauldie et al 1994) and inductively coupled plasma mass spectrometry (ICPMS) (Edmonds et al 1991, Dove et al 1996 are among the techniques which have been used to analyze otoliths. However, it is ICPMS whlch has emerged as the instrument of choice for such assays, due largely to its capability for rapid and accurate isotopic and elemental assays over a wide range of elements and concentrations (Table 3).…”

“…Perhaps more importantly, ontogenetic effects and age-related differences in exposure history can result in very different fingerprints for fish of different size-classes from the same population (Papadopoulou et al 1980, Edmonds et al 1989, Grady et al 1989, Hoff & Fuiman 1993, 1999a, Begg et al 1998. Since the elemental fingerprint reflects the exposure of the individual fish to both the environment and its own physiology, it would be expected to differ among any groups of fish which have experienced different histories, whether or not the groups come from the same population.…”

“…However, group-specific variation in elemental composition appears to be common (Edmonds et al 1989, Northcote et al 1992, 1999a, Bronte et al 1996, Thorrold et al 1998a. Since smaller fish seem far more likely to contain elevated (or depressed) concentrations of any given element than larger fish (Papadopoulou et al 1980, Edmonds et al 1989, Grady et al 1989, Hoff 81 Fuiman 1993, it is important that differences in elemental concentration among groups are not confounded by size differences among groups. Statistical removal of the effect of otolith weight on elemental concentration is a ready solution to this problem (Campana et al 1999a); (2) All possible groups contributing to the group mixture have been characterized.…”

ABSTRACT:The fish otolith (earstone) has long been known as a timekeeper, but interest in its use as a metabolically inert environmental recorder has accelerated in recent years. In part due to technological advances, applications such as stock identification, determination of rnigralon pathways, reconstruction of temperature and salinity history, age validation, detection of anadromy, use as a natural tag and chemical mass marking have been developed, some of which are difficult or impossible to implement using alternative techniques. Microsamphg and the latest advances in beam-based probes allow many elemental assays to be coupled with daily or annual growth increments, thus providing a detailed chronologcal record of the environment. However, few workers have critically assessed the assumptions upon which the environmental reconstructions are based, or considered the possibility that elemental incorporation into the otolith may proceed differently than that into other calcified structures. This paper reviews current applications and their assumptions and suggests future directions. Particular attention is given to the premises that the elemental and isotopic composition of the otolith reflects that of the environment, and the effect of physiological filters on the resulting composition. The roles of temperature, elemental uptake into the fish and the process of otolith crystahzation are also assessed. Drawing upon recent advances i n geochemistry and paleoclirnate research as points of contrast, it appears that not all applications of otolith chemistry are firmly based, although others are destined to become powerful and perhaps routine tools for the mainstream fish biologst.

“…A number of trace elements are known to contaminate skeletal aragonite, strontium being one of the most common (Amiel et al 1973)) due to its having the same valence as calcium (+2) and a similar ionic radius (Ca, 0.99A; Sr, 1.13A). Reasons for variations in the elemental composition of otolith aragonite range from simple geographical effects (Calaprice 1971)) temperature (Gauldie &Nathan 1977, Gauldie et al 1980, Gauldie et al 1986), pollution (Papadopoulou et al 1980), and age (Bennett et al 1982). It is the temperature effects which may be most valuable to ecologists in reconstructing life history patterns based on the elemental composition of otoliths.…”

Strontium:cakium concentration ratios in otoliths of herring larvae as indicators of environmental histories

et al. 1990

SynopsisElemental analyses, using wave-length dispersive electron microprobe techniques on otoliths from reared Atlantic herring larvae, Clupea harengus, showed trace quantities of strontium relative to that of calcium, and an inverse relationship between Sr/Ca concentration ratios and rearing temperature. These data are consistent with those for coral aragonite, in that there appears to be an inverse temperature effect on physiological incorporation of strontium in the otolith aragonite. Our determinations of Sr/Ca concentration ratios of lab-reared herring larvae showed that the deposition of strontium relative to calcium and the rearing temperature were related, where: T ("C) = -2.955 [S&a] x 1000 + 19.172. This principle thus makes it possible to use Sr/Ca concentration ratios in fish otoliths to delineate past temperatures experienced by an individual. Further, combining electron microprobe analyses with scanning electron microscope (SEM) examinations of daily increments in the same otolith makes it possible to reconstruct the temperature history for an individual fish on a time scale of days. An example of the application of the technique to an approximately six-month-old field-caught herring larva is given, and the limitations of the technique are discussed.

“…Site-specific differences in otolith elemental composition have been reported previously, but interpretation has generally been confounded by ontogenetic effects, assay limitations, and unexpected differences among samples (Papadopoulou et al 1980.

Trace elements incorporated into the growing surface of the fish otolith (ear stone) reflect the physical and chemical characteristics of the ambient water, although not necessarily in a simplistic manner. Since otoliths grow continuously without resorption throughout the life of the fish, fish population~ growing up in different water masses should produce otoliths of different elemental composition. The otolith elemental composition ('fingerprint') determined with isotope dilution -inductively coupled plasma mass spectroscopy (ID-ICPMS) proved to be an effective discriminator of adjacent population~ of Atlantic cod Gadus morhua off the coast of eastern Canada, with sufficient accuracy as a natural tag to determine population identity in a mixed population fishery. Classification of samples collected from the winter cod fishery on the eastern Scotian Shelf indicated that the annual winter migration out of the Gulf of St. Lawrence is more extensive than was previously believed.
