| Notes | The otolith is a small calcium carbonate structure found in the inner ear of vertebrates. In fisheries, otoliths have been used to age fish. This article describes a technique to use otolith shapes and morphology to identify different stocks of Chinook salmon. “We found best performance of the model occurring between hemispheres, followed by Oregon basins, within-watershed Elk River, Oregon, and lastly among South American basins. Otolith shape analysis is a promising tool for stock discrimination if used in conjunction with other methods to better understand plasticity of anadromous species that use pan-environmental systems” (from the Abstract). |
