| 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 interesting Master’s Thesis describes a technique to use otolith shapes and morphology to identify different stocks of Chinook salmon. The author notes that, “fishery managers are concerned with successful identification of mixed origin Chinook salmon stocks, as well as the health and condition of hatchery-origin fish and their impacts on wild populations. Therefore, this thesis examines ways to improve stock discrimination to provide a more useful tool for fishery managers.” Color photographs. |
