  abstract = {{E}nvironmental conditions experienced by aquatic organisms are archived in biogenic carbonates such as fish otoliths, bivalve shells and coral skeletons. {T}hese calcified structures present an accretionary growth and variations in optical properties (color or opacity) that are used to reconstruct time. {H}owever, full and reliable exploitation of the information extracted from these structures is often limited as the metabolic processes that control their growth and optical properties are poorly understood. {H}ere, we propose a new modeling framework that couples both the growth of a biogenic carbonate and its optical properties with the metabolism of the organism. {T}he model relies on well-tested properties of the {D}ynamic {E}nergy {B}udget ({DEB}) theory. {I}t is applied to otoliths of the {B}ay of {B}iscay anchovy {E}ngraulis encrasicolus, for which a {DEB} model has been previously developed. {T}he model reproduces well-known otolith patterns and thus provides us with mechanisms for the metabolic control of otolith size and opacity at the scale of an individual life span. {T}wo original contributions using this framework are demonstrated. (1) {T}he model can be used to reconstruct the temporal variations in the food assimilated by an individual fish. {R}econstructing food conditions of past and present aquatic species in their natural environment provides key ecological information that can be used to better understand population dynamics. (2) {W}e show that non-seasonal checks can be discriminated from seasonal checks, which is a well-recognized problem when interpreting fish otoliths. {W}e suggest further developments of the model and outline the experimental settings required to test this new promising framework.},
