Pacific salmon (Oncorhynchus spp.) are anadromous fish known for their extensive ocean migration and strong homing ability. To support these life history strategies, they rely on precise sensory mechanisms, including those mediated by the inner ear. Within the inner ear, sagittal otoliths - calcified structures composed primarily of aragonite - play a ...
