“…4) and strictly marine fish (Fig. 5) Maturation: Evidence from field and pen-reared mature marine fishes suggest that seasonal peaks in otolith Sr coincide with peak spawning (Kalish, 1991a;Granzotto et al, 2003;Clarke and Friedland, 2004;Sturrock et al, 2015). In Sturrock et al (2015), otolith Sr was positively related to gonadosomatic index in the females, with the peak occurring during the spawning period reflecting changes in plasma Sr/Ca that resulted from asynchronous cycles in plasma Sr and Ca concentrations (plasma Sr peaking about two months later than Ca).…”

The definitive publisher-authenticated version is available on the publisher Web site.physiological (ontogeny and growth) histories. A consistent temperature response was not evident across studies for either environmental or physiological tracers, presumably attributable to variable relationships between temperature and fish behavior and physiology (e.g., feeding rate, reproduction). Biomineralization thus has a controlling effect on otolith element concentrations for elements that are linked with somatic growth, but not for elements that substitute for Ca in the crystal lattice. Interpretation of the ecological significance of patterns from field samples therefore needs to consider the impact of the underlying biomineralization processes of the element in question as well as physiological processes regulating the availability of ions for inclusion in the growing crystal lattice. Such understanding will enhance the utility of this technique to address fisheries management questions.

“…In eastern TABACOD cod, there are nevertheless weak signals that seemingly correspond to seasonal patterns in Sr. Evidence from a range of species suggests that seasonal peaks in otolith Sr coincides with peak spawning (Clarke and Friedland, 2004;Granzotto et al, 2003;Kalish, 1991;Sturrock et al, 2015) reflecting a change in Sr availability in the blood plasma (Sturrock et al, 2015). However, in this study highest Sr concentrations occur during winter, while the peak spawning time of eastern Baltic cod is in July -August (Bleil et al, 2009;Wieland et al, 2000).…”

Accurate age data is essential for reliable fish stock assessment. Yet many stocks suffer from inconsistencies in age interpretation. A new approach to obtain age makes use of the chemical composition of otoliths. This study validates the periodicity of recurrent patterns in 25Mg, 31P, 34K, 55Mn, 63Cu, 64Zn, 66Zn, 85Rb, 88Sr, 138Ba, and 208Pb in Baltic cod (Gadus morhua) otoliths from tag-recapture and known-age samples. Otolith P concentrations showed the highest consistency in seasonality over the years, with minima co-occurring with otolith winter zones in the known-age otoliths and in late winter/early spring when water temperatures are coldest in tagged cod . The timing of minima differs between stocks, occurring around February in western Baltic cod and one month later in eastern Baltic cod; seasonal maxima are also stock-specific, occurring in August and October, respectively. The amplitude in P is larger in faster-growing western compared to eastern Baltic cod. Seasonal patterns with minima in winter/late spring were also evident in Mg and Mn, but less consistent over time and fish size than P. Chronological patterns in P, and to a lesser extent Mg and Mn, may have the potential to supplement traditional age estimation or to guide the visual identification of translucent and opaque otolith patterns used in traditional age estimation

“…Several studies have shown that the rate of uptake of Sr into the otolith is relatively high during periods of slow growth (Miller and Hurst, 2020;Mugiya and Satoh, 1997;Sadovy and Severin, 1994;Sturrock et al, 2014;Walther et al, 2010). While in some species, otolith Sr maxima have been associated with maturation and reproduction (Clarke and Friedland, 2004;Granzotto et al, 2003). It is unlikely that the seasonal differences observed in this study are linked to reproduction as the variation in otolith Sr was evident in the smallest size class (<31 cm) which included immature individuals.…”

“…These approaches rely on the identification of cyclical variation in elemental concentrations (Hüssy et al, 2015;Siskey et al, 2016) and the analysis of seasonal differences, as reported here. Alongside a growing understanding of the relationship between visible growth features and elemental composition (Granzotto et al, 2003;McFadden et al, 2016;Tomas et al, 2006;Tzeng et al, 1999), our results can help to advance the interpretation of visual growth marks and improve age estimation.…”

The incorporation of trace elements into the calcified structures of fish can vary seasonally. Interpretation of these seasonal signals can provide information about fish age. This approach offers great promise for objectively estimating age and corroborating other methods of age estimation for fish stock assessment. This study investigated seasonal variation in trace element composition of otoliths and illicia from white anglerfish (Lophius piscatorius L.), a species that is very difficult to age using visual interpretation of growth bands in their calcified structures. A suite of trace elements (Na, Mg, Zn, Sr, Ba in illicia and Na, Mg, K, Sr, Ba in otoliths) was measured with LA-ICPMS using discrete ablations and continuous line scans. A method is presented to obtain reliable measurements of microchemical composition from illicia. Variation in elemental concentrations at the edge of the illicium was primarily related to fish length and no differences were detected between fish collected at different times of the year. In otoliths, Sr concentrations at the edge (0-100 μm) were highest in anglerfish collected during wintertime (quarter 1). Seasonal differences in Sr were statistically significant but small; a larger proportion of the explained variance was attributed to length and individual variability. Nonetheless, the seasonal pattern was consistently detected across all size classes, indicating that the analysis of cycles in otolith Sr could potentially provide a tool to support age estimation in white anglerfish.
