Salmon are the biological foundation of river ecosystems Salmon runs function as enormous pumps that push vast amounts of marine nutrients from the ocean to the headwaters of otherwise low productivity rivers.
What would happen if there were no salmon?

What organisms benefit from salmon?
More than 130 animal species, including the Orca whale and the Grizzly Bear, feed on salmon and reap the benefits of the protein and nutrients contained in the fish. Salmon are also a central part of the human diet, especially for indigenous coastal communities who have fished salmon for thousands of years.
Why salmon are keystone species?
Salmon are considered keystone species on the B.C. Coast, meaning there are many species that rely on salmon. Because so many organisms rely on salmon as an essential food source, the salmon population is very important in maintaining biodiversity on the B.C. Coast. Salmon gain a lot of their mass while in the ocean.
Is salmon good for the environment?
According to them, it’s one of the safest options—and can be safely consumed at least once a week! It supports natural ecosystems. Put simply, wild salmon are a key part of a healthy river ecosystem. Think about it, they’re an essential source of protein for bears.
Why we should save the salmon?
Salmon are the biological foundation of river ecosystems
Salmon runs function as enormous pumps that push vast amounts of marine nutrients from the ocean to the headwaters of otherwise low productivity rivers.
Will salmon become extinct?
No, salmon are not endangered worldwide. For example, most populations in Alaska are healthy. Some populations in the Pacific Northwest are much healthier than others.

What happens when you eat salmon everyday?
Salmon health benefits
While many types of seafood contain omega-3 fatty acids, fish like salmon, herring, cod, and trout are particularly rich in omega-3 fatty acids, which is known to contribute to heart health by decreasing the risk of blood clots and lowering blood pressure.
How do salmon help forests?
Feeding the Forest
Incoming salmon keep forest soils fertile. Due to gravity and erosion, forests continuously lose soil and nutrients to the water. Migrating salmon reverse this process by eating fish and krill at sea and bringing nutrient-rich body mass back into the forest.
How often should you eat salmon?
two to three times a week
Fish and shellfish in this category, such as salmon, catfish, tilapia, lobster and scallops, are safe to eat two to three times a week, or 8 to 12 ounces per week, according to the FDA.

Is salmon more sustainable than beef?
In some ways, salmon is a greener option than meat. The salmon production industry is relatively well managed in comparison to livestock production. In terms of water usage, salmon is less water-intensive than land-based proteins to produce. Salmon’s freshwater consumption uses 2000 litres per kilogram of edible meat.
How are humans helping salmon?
At and Around the Home
- Reduce runoff.
- Avoid paving or use permeable or porous pavement.
