 Here are some interesting facts about Atlantic Salmon. Atlantic salmon is called Salmon Salar and is the leaper fish, popular for leaping against the current and swimming along to its spawning grounds. Salmon is also commercially known as Bay Salmon, Caplin-scull salmon, Fiddler, Grilse, Grilt, Kelt, Landlocked Salmon, Ouanaciche, Outside salmon, Parr, Sebago Salmon, Silver Salmon, Slink, Smolt, Spring Salmon or Winnish.



  1. The US Atlantic salmon were once native to almost every river north of the Hudson River. The remaining wild populations are now known only in 11 rivers.
  2. The Salmon have an anadromous fish migration pattern in that they feed and grow large in saltwater and return to spawn in freshwater. The freshwater phase of these varies depending on the river locations.
  3. The Salmon has a complex life history including the spawning, juvenile rearing in rivers and feeding migration on high seas. Changes in behavior, physiology and habitat requirements are notable features.
  4. They go through the Alevin, Fry, Parr and the Smolt stage.  Females returning to spawn, after spending two winters at sea will lay an average of 7,500 eggs of which only about 15-35% will survive to the fry stage.
  5. Salmon Parr is an interesting stage. When eggs hatch and become Fry in april-march. Fry remains buried in the gravel for about 6 weeks and emerge mid May feeding. They develop camouflaging stripes along their sides and enter the parr stage. Parr habitat is called the nursery habitat with good cover and adequate depth.
  6. Salmon Parr spend 2-3 years in freshwater and then undergo a physiological transformation called ‘smoltification’ that prepares them for life in a marine habitat.
  7. Even with all the conservation efforts returns of Atlantic salmon to the Gulf of Maine remains low. Conservation efforts are on to keep the numbers. The good thing is Salmon can be farmed to raise the numbers.
  8. Salmons are very sensitive to changes in water conditions, pollution and other environmental factors which could reduce their survival rates. Logging, soil erosion, change in water temperature or pollution add to their decline.
  9.  Salmon is a good source of protein, but contain a very high level of omega-3 essential fatty acids as well. It can also provide a significant amount of several vitamins and minerals like, vitamin A, vitamin B1 or thiamine, riboflavin, niacin, vitamin B6, folate, vitamin B12, vitamin D, calcium, magnesium, potassium, sodium, zinc, copper, manganese, selenium and phosphorus.
  10. The NASCO (North Atlantic Salmon Conservation Organization) council is made up of Canada, Denmark, the European union, Iceland, Norway, the Russian Federation and the United States, with its headquarters in Edinburgh. It was established in 1983 to protect the Atlantic salmon their habitat and also restore their habitats by co-operation between nations.

These facts about Atlantic Salmon are quite interesting indeed!
