Salmon is more than just a delicious dish—it’s a fish with a life full of extraordinary feats and surprising facts.
Here are 15 weird and wonderful things about salmon that will give you a whole new appreciation for this remarkable species.
1. Salmon Can Spawn Multiple Times
Not all salmon die after spawning—some, like the steelhead, can make the journey to spawn multiple times, going back and forth between the ocean and freshwater.
2. Salmon Can Change Their Sex
Certain salmon species, like pink salmon, can actually change their sex during their lives, often in response to changes in their environment or population.
3. Salmon Can Experience Stress
Salmon are super sensitive to their surroundings, and stress can mess with their health and migration. Pollution, temperature shifts, and habitat loss can all crank up their stress levels.
3. Anadromous Life Cycle
Salmon are anadromous, which means they’re born in freshwater, migrate to the ocean to grow, and then return to freshwater to spawn. This incredible journey can cover thousands of miles and is one of nature’s most impressive feats.
4. Incredible Sense of Smell
Salmon possess an extraordinary sense of smell, capable of detecting one part per million of certain scents. This keen sense helps them navigate back to their birthplace when it’s time to spawn.
5. Color Change During Spawning
As salmon prepare to spawn, they undergo dramatic color changes. For example, sockeye salmon transform from a silvery hue to a vibrant red with a green head—talk about a makeover!
6. Have Incredible Jumping Ability
Salmon are famous for their impressive jumping skills. Some species can leap up to 12 feet high, allowing them to overcome obstacles like waterfalls during their upstream migration.
7. Lifespan Variability
Depending on the species, salmon can live anywhere from 3 to 9 years. Chinook salmon, for instance, can live up to 9 years, while others may only survive a few years.
8. Produces Massive Amounts of Egg
A female salmon can lay between 1,500 and 10,000 eggs in a single spawning season. However, only a tiny fraction of these eggs will survive to adulthood, showcasing the harsh realities of nature.
9. A Core Species In The Ecosystem
Salmon are considered a keystone species in their ecosystems. Their nutrient-rich bodies provide essential food for wildlife like bears and eagles, and even nourish trees when their carcasses decompose.
10. Has Unique Migration Patterns
Some salmon species, like the Chinook, embark on epic journeys, traveling over 2,300 miles upstream to spawn. This is one of the longest migrations of any fish.
11. Salmon Bones Are Edible
The bones in canned salmon are soft and edible, offering a great source of calcium. Many people consume them without even realizing it, adding a crunchy bonus to their meal.
11. Salmon and Their Diet
Salmon primarily feast on smaller fish, crustaceans, and insects. Their diet is rich in carotenoids, which give their flesh its distinctive pink and orange colors.
12. Salmon Went To Space Before You Did
In 1984, salmon eggs were sent to space as part of an experiment to study their development in microgravity. Remarkably, they successfully hatched and grew into fry.
15. Farmed Salmon Now The Norm
The global demand for salmon has led to a rise in aquaculture, with farmed salmon now accounting for a significant portion of the salmon consumed worldwide. However, this has raised concerns about sustainability and environmental impact.
From their epic migrations to their crucial role in ecosystems, salmon are much more than just a tasty fish.
