In a January 18, 2019 post<\/a>, I related the state of Washington\u2019s plan to increase the state\u2019s hatchery salmon production to recover salmon populations and help the endangered southern population of killer whales.\u00a0 In response to an executive order by the governor of Washington, the Washington Department of Fish and Wildlife\u2019s proposed<\/a> broad measures to increase the numbers of hatchery-raised salmon smolts released into killer whale migration areas that have minimal numbers of wild salmon.\u00a0 The program would also enhance commercial and sport fisheries for salmon.\u00a0 Much of the hatchery program would remain committed to recovery of threatened and endangered wild salmon stocks, which would also get a boost in essential habitat restoration.<\/p>\n

The proposal in Washington state calls for an additional 30 million smolts for the Puget Sound estuaries (near Seattle) and an additional 20 million for the Columbia River estuaries, 50 and 20 percent increases, respectively.\u00a0 The proposal recognizes:<\/p>\n

\u00a0[H]atchery practices can pose serious genetic and ecological risks to wild populations if not managed carefully with full consideration of all that has been learned over the history of salmonid hatchery programs in the Pacific Northwest. However, the design of this proposal strives to minimize such negative impacts and to afford protection to the existing wild chinook populations to the greatest extent possible.<\/p><\/blockquote>\n

Elements of the program would include releasing hatchery smolts in lower river and estuary areas.\u00a0 The program is designed to minimize effects on wild salmon by keeping these releases outside of the normal rearing and migration routes of wild salmon. \u00a0In some cases, hatchery salmon fry would be transported to net pens in lower rivers and estuaries for rearing and eventual release of smolts near the ocean, thereby further increasing smolt survival.\u00a0 Returning adult salmon would home in on such sites, creating opportunities for terminal fisheries for hatchery salmon while retaining upriver spawning grounds for wild salmon.<\/p>\n

A similar program is being planned and tested in California in the San Francisco Bay Estuary of the Sacramento and San Joaquin rivers.\u00a0 Central Valley hatchery salmon smolts are already being trucked to the Bay and nearby coastal estuaries.\u00a0 A new program element under consideration is the trucking of fry to local Bay estuary net pens for rearing.\u00a0 If successful, this would create new terminal sport and commercial fisheries, while enhancing coastal fisheries and prey for the California Killer Whale populations.<\/p>\n

One goal of the program in California would also be to shift hatchery salmon fisheries away from rearing areas and migration routes of wild salmon.\u00a0 Rearing fry and releasing smolts in areas not frequented by wild salmon should reduce the effects of the hatchery program on wild salmon.\u00a0 Similarly, terminal fisheries would focus harvest away from migration routes of wild salmon and reduce competition with wild salmon in spawning areas in upper rivers.\u00a0 Commercial and sport fisheries would be enhanced along the coast.\u00a0 New terminal fisheries would be created at estuary and coastal release sites that attract adults originally released at the sites as smolts.<\/p>\n

If all goes well, such programs will benefit killer whales, sport and commercial fisheries, and wild salmon population (through reduced competition and better harvest management).<\/p>\n
