| Despite numerous applications on the use of otoliths at both population and individual levels, knowledge regarding the mechanisms of the otolith and their variations with environmental and physiological factors has to be improved. In particular, the characterization of mineral and organic fractions of the otolith structures and the influence of their qualitative and quantitative composition on the opacity remain poorly documented. Yet this information is of key interest for the calibration of the archive "otolith" allowing a robust analysis of information. The first issue of this study focused on the analysis of the opacity and the effects of temperature, growth and metabolism through experiments in controlled conditions. Results led to the modelling of... |
