鱼类耳石包含了相当多的生活史、环境和生理信息。当适当的分析方法，基于对耳石的结构和化学变化的机制的理解，可以辨别出这些信息。耳石碳酸盐的沉积可能受到许多相互作用的因素的调节，包括年龄，生理，环境压力，营养的可用性，环境温度，昼夜和季节周期，以及个体鱼类的活动水平。基因组控制和环境条件之间的复杂相互作用将最终决定沉积模式。耳石的化学组成受鱼类生理活动的调节，而鱼类生理活动又受环境条件的影响。野生鱼类的化学模式的解释必须通过分析实验条件下保持的鱼类的沉积模式进行验证。微化学分析可以提供关于个别鱼类的生活史概况和环境史数据，以澄清年龄和生长轨迹的解释。有几个因素可能有助于报告的差异元素的研究，包括次优的饲养环境，生长速度的热效应，耳石化学和营养的影响。在人工条件下获得的描述生长和耳石结晶的代谢数据仅与模拟环境的细微之处大致相似，可能具有有限的价值，并且在将结果外推到自然系统时应谨慎。
A considerable aggregate of life-history, environmental and physiological information is incorporated within fish otoliths. This information may be discerned when appropriate analytical methods, based on an understanding of the mechanisms underlying changes in the structure and chemistry of otoliths, are utilized. Deposition of otolith carbonate may be regulated by many interacting factors, including age, physiology, environmental stress, availability of nourishment, ambient temperature, diurnal and seasonal cycles, and activity levels of individual fish. Complex interactions between genomic control and environmental conditions will ultimately govern depositional patterns. The chemical composition of otoliths is regulated by the physiological activity of fish, which in turn is influenced by environmental conditions. Interpretation of the chemical patterns in wild fishes must be validated by analysing the depositional patterns in fishes maintained under experimental conditions. Microchemistry analyses can provide life-history profiles and data on the environmental history of individual fish to clarify interpretation of age and growth trajectories. Several factors may contribute to the reported disparity in elemental studies, including suboptimal rearing environments, thermal effects on growth rate, and nutritional effects on otolith chemistry. Metabolic data describing growth and otolith crystallization obtained under artificial conditions that only grossly resemble the subtleties of the modelled environment may have a limited value and caution should be used when extrapolating results to natural systems.
