“…So far, this approach has been successful in simulating otolith growth and opacity patterns for larval and adult fish. In particular, the inverse opacity patterns exhibited by Barents Sea (translucent zones during cold months) and southern North Sea (translucent zones during warm months) cod has been reconstructed, which shows that the techniques holds promise with regard to being able to explore not only population-specific responses, but potentially also individual or genotype responses (Fablet et al 2011). The models can also be run 'backwards' using ambient temperature and observed otolith opacity patterns to reconstruct individual growth and food intake (Pecquerie et al 2012).…”

“…Two lines of research have dominated the research into otolith increment formation, one driven by studies of the chemical properties of the endolymph, its relationship with the crystallisation of aragonite and dependence on exogenous factors (Morales-Nin 2000; Guibbolini et al 2006), which have shown that changes in opacity represent variations in the relative fractions of mineral and organic matter in the otolith zones (Mugiya 1984;Morales-Nin 2000;, and the other focussed on bioenergetic modelling of the link between otolith growth, opacity and the metabolism of the individual Fablet et al 2011;Pecquerie et al 2012). In addition to these approaches, numerous field and laboratory experiments have investigated the width and frequency of increment formation under different conditions and provided empirical data for the modelling.…”

“…A promising approach to further explore the links between environment, physiology and otolith characteristics is the use of dynamic energy budget (DEB) models to simulate otolith growth and opacity (Fablet et al 2011;Pecquerie et al 2012). Within this framework the mineral and organic fractions of the otolith are regarded as individual metabolic products involving contributions from somatic growth and maintenance DEB fluxes and so, to some extent, combine hypotheses of standard metabolism v. SDA as drivers of otolith growth.…”

Abstract. Otoliths are remarkable recorders that store visual and chemical information that can be interpreted with regard to individual fish phenotype trajectory, life history events and environment. However, the information stored in the otoliths must be interpreted with the knowledge that the otolith is an integral part of fish sensory systems. This means that the environmental signals recorded in the otoliths will be regulated by the homeostatic apparatus of the individual fish -its physiology and ultimately its genetic make-up. Although this may complicate interpretation of environmental signals, it also opens up avenues for new research into the physiology and life history of individual fish. This review focuses on research areas where the coupling between otolith characteristics and fish physiology may yield new insights. Most of the research ideas are by no means new, but rather represent largely forgotten or less-explored research areas. Examples of questions that are fundamental, unanswered and with the potential to yield significant new insights are those related to the coupling of otolith and fish growth through metabolism, and the formation of opaque and translucent growth zones in relation to the physiology of the individual. An integration of visual and chemical data with bioenergetic modelling may yield some of the answers.

“…Mn; Brophy et al 2004;Macdonald et al 2008). Similarly, heterogeneity in the protein content of opaque and translucent regions of the otoliths (Hüssy et al 2004;Fablet et al 2011) will likely result in seasonally variable elemental concentrations (e.g. Kalish 1989;Sturrock et al 2015).…”

Abstract. Otolith element analyses are used extensively to reconstruct environmental histories of fish based on the assumption that elements substitute for calcium within the CaCO 3 otolith structure. However, elements may also be incorporated within the protein component of the otolith in addition to the direct substitution for calcium in the mineral component, and this could introduce errors in environmental reconstructions. The aim of the present study was to determine whether elements were incorporated into the protein or mineral components of otoliths and the relative proportion of each element in each component. Element concentrations from whole ground otoliths and the isolated protein component were quantified using solution inductively coupled plasma mass spectrometry (ICP-MS). Of the 12 elements investigated, most were found in both the proteinaceous and mineral components, but always in greater concentrations in the latter. Elements considered 'non-essential' to fish physiology with Ca-like properties (i.e. alkaline metals) were present in the mineral component in relatively high concentrations. Elements essential to fish physiology with smaller atomic radii than Ca (i.e. transition metals) were distributed throughout the protein and mineral components of the otolith. These findings enhance our understanding of element incorporation in the otolith and, ultimately, improve interpretations of otolith-based environmental reconstructions.Additional keywords: CaCO 3 , calcium carbonate, element incorporation, ICP-MS, inductively coupled plasma mass spectrometry, protein.

“…Environmental factors can also play a role, and poor feeding conditions (Neilson and Geen 1985) in addition to temperature and photoperiod (Beckman and Wilson 1995) have been shown to affect otolith opacity. Theoretical advances in the modeling of fish otolith biomineralization using a bioenergetic approach have also recently been reported (Fablet et al 2011).…”

A description of four types of otolith opaque zone

Analysis of the alternating opaque and translucent zones in fish otoliths is a widely used method to determine age in fish. The mechanisms underlying the annual periodicities in the formation of these zones remain unknown, although various interpretations and explanations have been presented to explain the appearance of the opaque zones. Here I review the biological and structural characteristics of the opaque zones in otoliths from a number of fish species. The results of this review suggest that the opaque zones can be classified into four different types. Type A is a dark opaque zone, displaying minute, dense crystals, and is typically formed at a young life-history stage. Type B comprises an aggregation of grooves and discontinuous crystals that are formed during growth-stagnant periods. Type C can be described as a washy black zone that has the appearance of an object that is smeared with ink; it is formed during seasons of active growth. Type D has deep grooves, appears luminous in transmitted light in etched otolith sections, and is formed during the spawning season. Types A and C otolith opaque zones are typical of younger fish and are formed during growing periods. They are complementary to Types B and D otolith opaque zones which are formed during periods of stagnant growth and/or during the spawning seasons and which are typical of older fish, which generally lack Type A zones. To ensure precise age determination in fish, it is therefore necessary to understand the structural and biological characteristics that produce these four distinct types of opaque zones.
