Chum Catch levels of Alaskan chum are high, though they have been declining since the record commercial catch of 13 million fish in 1984. Hatchery fish make up an increasing share of the commercial catch, amounting to more than one in four fish. Of twenty-two chum stocks extinct in the province, seventeen had been found in the Vancouver area. Most Washington chum runs are healthy, with the exception of two Puget Sound stocks in critical condition and lower Columbia River populations, which are declining. Chum are in critical condition in Oregon, where many populations are already extinct.
Few chum remain in California.
Coho Data on coho in Alaska are sparse, except in the south-central part of the state. In general, escapement is increasing throughout the state, with the exception of southeast Alaska. In recent years, Alaska has seen record commercial catches of coho. In British Columbia, coho runs are declining. By 1992, escapement had reached the lowest levels since the 1950s.
