the catch was from Japan, and about a quarter each from Russia and the United States. The chum salmon harvest was about 34% of the total harvest of all Pacific salmon species by weight. The chum salmon is the least commercially valuable salmon in North America. Despite being extremely plentiful in Alaska, commercial fishers often choose not to target them because of the low market value. Recent market developments have increased the demand for chum salmon, due to new markets developed from 1984 to 1994 in Japan and Northern Europe. They are a traditional source of dried salmon. Conservation Two populations of chum salmon have been listed under the Endangered Species Act as threatened species. These are the Hood Canal Summer Run population and the Lower Columbia River population. Susceptibility to diseases Chum are thought to be fairly resistant to whirling disease, but it is unclear.
