Effects of Marine Mammals on Columbia River Salmon Listed under the Endangered Species Act : Recovery Issues for Threatened and Endangered Snake River Salmon : Technical Report 3 of 11.
Most research on the Columbia and Snake Rivers in recent years has been directed to downstream migrant salmon (Oncorhynchus spp.) losses at dams. Comparatively little attentions has been given to adult losses. Recently an estimated 378,4000 adult salmon and steelhead (O. mykiss) were unaccounted-for from Bonneville Dam to terminal areas upstream. It is now apparent that some of this loss was due to delayed mortality from wounded by marine mammals. This report reviews the recent literature to define predatory effects of marine mammals on Columbia River salmon.
