Orcas need bountiful salmon runs
WILD SALMON NEWS A project of the Save Our Wild Salmon Coalition
Special Naturalists' page on salmon and toxins
Southern Resident orcas depend on bountiful Chinook salmon runs, which, in turn depend on abundant forage fish. Here is a summary of Puget Sound's forage fish.
Overall salmon runs are in deep and historic decline, and persistent Toxic Contamination, especially polychlorinated biphenyls (PCBs) and other organic chemicals, like DDT and persistent aromatic hydrocarbons (PAHs), continue to leach into the marine ecosystem and move inexorably through the food web. Over decades these contaminants have gradually become lodged in the whales' blubber layers in massive quantities, sometimes with lethal results.
Levels of PCBs and PBDEs (flame-retardants added to manufactured products) attach to fat cells and accumulate over the life of marine mammals, severely impairing development and immunity in orcas, but fortunately are gradually decreasing throughout the marine food web, including in orcas and humans.

Ecological Contexts, Relationships, and Implications for Management

The LA Times report shows how habitat degradation harms orcas.
"Salmon act as an ecological process vector, important in the transport of energy and nutrients between the ocean, estuaries, and freshwater environments. The flow of nutrients back upstream via spawning salmon and the ability of watersheds to retain them plays a vital role in determining the overall productivity of salmon runs. As a seasonal resource, salmon directly affect the ecology of many aquatic and terrestrial consumers, and indirectly affect the entire food web. The challenge for salmon, wildlife, and land managers is to recognize and account for the importance of salmon not only as a commodity resource to be harvested for human consumption, but also for their crucial role in supporting overall ecosystem health. It is also important that the naive view of wildlife as only consumers of salmon be abandoned. Many species of wildlife for which hard earned environmental laws and significant conservation efforts have been established (e.g., grizzly bears, bald eagles, river otters, killer whales, beaver), play key roles in providing for the health and sustainability of the ecosystems upon which salmon depend. As the health of salmon populations improves, increases in the populations of many of the associated wildlife species would be expected. Salmon and wildlife are important co-dependent components of regional biodiversity, and deserve far greater joint consideration in land-management planning, fishery management strategies, and ecological studies than they have received in the past."
Our own population continues to grow, while our biological support system shrinks.
If the orcas could say only one thing to us, it would probably be:
"Bring back the fish."

Save Our Wild Salmon's Columbia & Snake Rivers Campaign
When Lewis and Clark encountered the Snake River (and the Indian people who helped to save their lives) in 1805, five to eight million wild adult salmon returned from the Pacific Ocean to the Snake each year. Today, after the 200th anniversary of Lewis and Clark's expedition, a mere five thousand wild salmon, of all species, return to the Snake. All five species of Snake River salmon and steelhead are listed under the Endangered Species Act, headed toward extinction. The primary reason is that eight federal dams and reservoirs now lie between the inland streams where salmon are born and the ocean where they spend most of their lives.
The Save Our Wild Salmon Coalition was created in 1991 to unite conservationists, sport and commercial fishers, and salmon-based businesses in support of five principles:
The Nooksack Salmon Enhancement Association
- return salmon to their rivers: protect and restore spawning, rearing, and migratory habitat;
- conserve the genetic heritage and biological diversity of wild salmon populations;
- restore productive Tribal and non-Tribal fisheries that allow the rebuilding of wild salmon stocks;
- restore wild salmon at least cost to other river users and society as a whole;
- foster cooperation among all citizens committed to wild salmon recovery.

Organizations, Groups and Alliances dedicated to salmon restoration
- Save Our Wild Salmon is a nationwide coalition of conservation organizations, commercial and sportsfishing associations, businesses, river groups, and taxpayer advocates working collectively to restore self-sustaining, healthy, and abundant wild salmon to rivers, streams and oceans of the Pacific Salmon states.
- Wild Fish Conservancy is a leading advocate for the conservation and recovery of Washington’s wild-fish ecosystems.
- Georgia Strait Alliance, based in British Columbia, is involved in a wide variety of initiatives to improve the health of our coastal waters.
- Northwest Straits Marine Conservation Initiative "The Northwest Straits is a complex and diverse waterway, rich in beauty and economic benefits. But this ecosystem and some of its marine resources are in serious decline. Bottomfish, sea birds, invertebrates, salmon, and even some populations of marine mammals have declined precipitously since 1980."
- National Wildlife Federation strives "to protect the runs that we still have left and find ways to bring back the salmon that we have lost."
