Quantifying physiological influences on otolith microchemistry [PDF]
Methods in Ecology and Evolution, 2015 Trace element concentrations in fish earstones (‘otoliths’) are widely used to discriminate spatially discrete populations or individuals of marine fish, based on a commonly held assumption that physiological influences on otolith composition are minor ...

Phenotypic variation in otolith shape of American shad across eastern North American rivers [PDF]
Scientific ReportsOtolith shape analysis has been widely applied to study population structure and environmental influences in various fish species. However, research on American shad (Alosa sapidissima) otolith morphology remains scarce, despite its potential to provide ...

Investigating otolith mass asymmetry in six benthic and pelagic fish species (Actinopterygii) from the Gulf of Tunis [PDF]
Acta Ichthyologica et Piscatoria, 2021 Otolith mass asymmetry can significantly affect the vestibular system functionalities; usually, the X values of mass asymmetry vary between −0.2 and + 0.2 (−0.2 < X < + 0.2). These values can change during a fish life and therefore they are

Within-otolith variability in chemical fingerprints: implications for sampling designs and possible environmental interpretation. [PDF]
PLoS ONE, 2014 Largely used as a natural biological tag in studies of dispersal/connectivity of fish, otolith elemental fingerprinting is usually analyzed by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS).

Scientific Reports, 2021 Otoliths are commonly used to discriminate between fish stocks, through both elemental composition and otolith shape. Typical studies also have a large number of elemental compositions and shape measures relative to the number of otolith samples, with ...
