“…In the few studies to compare signatures, otolith matrix and muscle protein δ 13 C values are similar and highly correlated with one another, including using CSIA-AA (McMahon et al 2011a(McMahon et al , 2011b and bulk analyses (Godiksen et al 2019;Grønkjaer et al 2013;Sirot et al 2017). The same is true for CSIA-AA δ 15 N values (Vane et al 2018b) and bulk analyses (Cheng et al 2018;Lueders-Dumont et al 2020;Vandermyde & Whitledge 2008). Crossspecies comparisons revealed the potential for species-level differences in the N isotope fractionation in otoliths (e.g., Atlantic cod (G. morhua, and others in the Gadidae family).…”

“…Until recently, the majority of δ 15 N studies combined multiple otoliths to obtain enough N for elemental-analysis coupled to isotope ratio mass spectrometry (EA-IRMS) (Godiksen et al 2019;Grønkjaer et al 2013;Sirot et al 2017;Vandermyde & Whitledge 2008). However, advances using a persulfate-denitrifier method, allow N isotope measurements from small, individual otoliths (Cheng et al 2018;Lueders-Dumont et al 2018, 2020. For δ 13 C measurements of organics, otoliths are demineralized prior to isotopic analysis, facilitating measurements of organic C without dilution from the inorganic carbonate C that comprises most of the otolith mass (Godiksen et al 2019;Grønkjaer et al 2013;McMahon et al 2011aMcMahon et al , 2011bSirot et al 2017;Vane et al 2018a).…”

Chemical analysis of calcified structures continues to flourish, as analytical and technological advances enable researchers to tap into trace elements and isotopes taken up in otoliths and other archival tissues at ever greater resolution. Increasingly, these tracers are applied to refine age estimation and interpretation, and to chronicle responses to environmental stressors, linking these to ecological, physiological, and life-history processes. Here, we review emerging approaches and innovative research directions in otolith chemistry, as well as in the chemistry of other archival tissues, outlining their value for fisheries and ecosystem-based management, turning the spotlight on areas where such biomarkers can support decision making. We summarise recent milestones and the challenges that lie ahead to using otoliths and archival tissues as biomarkers, grouped into seven, rapidly expanding and application-oriented research areas that apply chemical analysis in a variety of contexts, namely: (1) supporting fish age estimation; (2) evaluating environmental stress, ecophysiology and individual performance; (3) confirming seafood provenance; (4) resolving connectivity and movement pathways; (5) characterising food webs and trophic interactions; (6) reconstructing reproductive life histories; and (7) tracing stock enhancement efforts. Emerging research directions that apply hard part chemistry to combat seafood fraud, quantify past food webs, as well as to reconcile growth, movement, thermal, metabolic, stress and reproductive life-histories provide opportunities to examine how harvesting and global change impact fish health and fisheries productivity. Ultimately, improved appreciation of the many practical benefits of archival tissue chemistry to fisheries and ecosystem-based management will support their increased implementation into routine monitoring.

“…In this study we were not able to separate otolith material laid down before and during the experiment. Recently, a highly sensitive method based on peroxodisulfate oxidation-bacterial conversion of organic material has been used to examine the d 15 N values of fish otoliths (Cheng et al 2018;Lueders-Dumont et al 2018). This method requires 1/200th the amount needed for traditional combustion-based methods and provides a promising approach to analyse d 15 N in the tiny amounts of otolith material laid down after a temperature or diet shift, for example.…”

Reconstruction of the trophic position of a fish can be performed by analysing stable nitrogen and carbon isotopes in otolith protein. However, ambient temperature may affect the tissue–diet isotopic spacing of stable isotopes from diet to predator tissue and bias estimates of trophic position. To test this, otolith protein, heart and muscle tissue from a rearing experiment with juvenile cod held at different temperatures (4, 7, 10 and 14°C) were analysed. There was no significant effect of temperature on otolith δ15N, whereas muscle and heart exhibited a slight decrease in δ15N values with increasing temperature corresponding to maximum of 0.6‰ over the 10°C range. By contrast, the otolith protein δ13C values at 4 and 7°C were significantly higher than for 10 and 14°C, suggesting an approximate 1‰ increased tissue–diet enrichment at the lower temperatures. Temperature had no significant effect on muscle and heart δ13C values. Considering the annual mean variation in ocean temperatures, our results indicate that the trophic signals recorded in the otoliths will reflect changes in diet isotope values with little bias from the ambient temperature experienced by the fish.

Mass Spectrometry‐based Techniques for Direct Quantification of High Ionization Energy Elements in Solid Materials—challenges and Perspectives

The determination of nonmetals, first of all, the most electronegative ones—nitrogen, oxygen, fluorine, chlorine, and bromine, poses the highest challenge for element analysis. These elements are characterized by high reactivity, volatility, high ionization energy, and the absence of intensive spectral lines in the optical spectral range. Conventional techniques of their quantification include considerable “wet chemistry” stages so the application of these techniques for the solid sample is highly laborious and prone to uncontrollable uncertainties. Additionally, current development in material science and other areas requires the quantification of the elements at lower levels with good sensitivity. Owing to their robustness and flexibility, mass spectrometry techniques provide vast possibilities for the quantification, spatial and isotopic analysis, including the solutions for direct analysis of solids. The current review focuses on the application of major mass spectrometric techniques for the quantification of N, O, F, Cl, and Br in solid samples. The following techniques are mainly considered: thermal ionization mass spectrometry (TIMS), isotope‐ratio MS (IRMS), secondary ion MS (SIMS), inductively coupled plasma MS (ICP‐MS), and glow discharge MS (GDMS); as the most accessible and widely applied for the purpose. General ionization issues, advantages, limitations, and novel methodological solutions are discussed. © 2020 John Wiley & Sons Ltd.
