- Size: 70-100 cm (28-40 in).
- Weight: 3.5-5.5 kg (8-12 lbs).
- Distribution: Northern Atlantic Ocean and coastal rivers.
- Habitat: Open ocean, freshwater river habitat for hatching.
- Diet: Juveniles eat insects and other invertebrates. Adults eat smaller fish (mostly capelin).
- Predators: Sharks, orcas, dolphins, seals large fish such as tuna or swordfish.
- Reproduction: They live in the ocean and migrate to rivers to breed. They dig a nest (called a redd) in the riverbed gravel, and lay on average 7,500 eggs.

20 Amazing Facts About The Atlantic Salmon
- Atlantic Salmon are known as the “King of Fish” due to their impressive size and majestic appearance. They can grow up to 4.9 feet (1.5 meters) in length and weigh over 100 pounds (45 kilograms) [^1^].
- These fish are anadromous, meaning they are born in freshwater rivers, migrate to the ocean to grow and mature, and then return to their natal rivers to spawn [^2^].
- Atlantic Salmon can jump up to 12 feet (3.7 meters) vertically, an impressive feat that allows them to navigate through waterfalls and rapids during their upstream migration to spawn [^3^].
- These fish can detect changes in the Earth’s magnetic field, which is believed to help them navigate during their long migrations between freshwater rivers and the ocean [^4^].
- Atlantic Salmon have a unique ability to change color throughout their lives, transitioning from a camouflaged pattern as juveniles in freshwater to a silvery sheen as adults in the ocean [^5^].
- Unlike Pacific Salmon, which die after spawning, Atlantic Salmon can spawn multiple times throughout their lives, a phenomenon known as iteroparity [^6^].
- Atlantic Salmon can travel up to 2,000 miles (3,200 kilometers) during their oceanic migration, with some even crossing the Atlantic Ocean [^7^].
- These fish possess a keen sense of smell, which is believed to help them find their natal rivers when they return to spawn. They can recognize the unique scent of the stream where they were born [^8^].
- Atlantic Salmon are opportunistic feeders, consuming a variety of prey, including small fish, shrimp, and squid, depending on their life stage and location [^9^].
- Climate change is impacting Atlantic Salmon, as rising water temperatures can affect their growth, migration, and reproduction. Warmer waters can also lead to increased disease and parasite prevalence [^10^].
- The Atlantic Salmon is considered a keystone species, playing a vital role in maintaining the health and balance of the ecosystems they inhabit [^11^].
- The age of an Atlantic Salmon can be determined by examining the growth rings on its scales, much like the rings of a tree [^12^].
- Female Atlantic Salmon can lay between 1,500 and 2,000 eggs per pound (3,300 to 4,400 eggs per kilogram) of body weight during spawning [^13^].
- The population of wild Atlantic Salmon has declined significantly in recent years due to factors such as overfishing, habitat degradation, pollution, and the construction of dams and other barriers that disrupt their migratory routes [^14^].
- Conservation efforts are underway to protect and restore Atlantic Salmon populations, including habitat restoration, dam removal, and the implementation of sustainable fishing practices [^15^].
- Atlantic Salmon have been farmed since the 1960s, and the majority of the salmon consumed worldwide now comes from aquaculture operations [^16^].
- The presence of Atlantic Salmon in a river can be an indicator of good water quality, as these fish require clean, well-oxygenated water to thrive [^17^].
- Some cultures, such as the indigenous peoples of North America and the Celtic people of Europe, have long revered the Atlantic Salmon, featuring the fish in their folklore, mythology, and art [^18^].
- The lifespan of an Atlantic Salmon varies depending on the individual and environmental factors, but they typically live for 3 to 8 years [^19^].
- Fossil evidence suggests that the Atlantic Salmon has been around for at least 10 million years, making it an ancient species with a long evolutionary history 1.

Where & How To See Atlantic Salmons in The Wild?
Witnessing Atlantic Salmon in their natural habitat can be an awe-inspiring experience. Here are some tips and locations to help you embark on this unforgettable adventure:
- Time your visit during their migration: The best time to spot Atlantic Salmon is during their migration season, which typically occurs between June and October. During this time, they return from the ocean to their freshwater spawning grounds 1.
- Head to Scotland or Scandinavia: Some prime locations to witness Atlantic Salmon in the wild include the rivers of Scotland and Scandinavia. In Scotland, you can visit the River Tweed, River Tay, or River Spey 2. In Scandinavia, consider visiting the Tana River, which forms the border between Norway and Finland 3.
- Visit national parks: National parks offer great opportunities for Atlantic Salmon sightings. In the United States, you can visit the Penobscot River in Maine, where the Gulf of Maine Atlantic Salmon Recovery Plan is in place to help restore the salmon population 4. In Canada, you can visit Fundy National Park in New Brunswick, which has a unique tidal ecosystem and numerous rivers where salmon spawn 5.
- Take part in organized tours or guided fishing trips: Many tour operators and fishing guides offer specialized trips tailored to the Atlantic Salmon experience. These professionals can help you find the best spots and times to see these magnificent fish. Remember to follow catch-and-release practices if you plan on fishing to help protect the species 6.
- No need to dive: You don’t necessarily need to dive to see Atlantic Salmon. You can often observe them from the riverbanks or bridges as they leap upstream to navigate rapids and waterfalls during their migration 7.
- Practice responsible wildlife viewing: Always follow ethical wildlife viewing guidelines. Keep a respectful distance from the salmon and their habitat, and avoid disturbing or disrupting their natural behavior 8.
