Guides Who Fish This Species

Atlantic Salmon (Salmo Salar) 


Atlantic salmon is the only one in the salmon species that exist in the Atlantic Ocean. It is also the second-largest in the salmon species. They have a long and slim body with a forked tail and an almost square tail fin. The head is relatively small compared to the body. When adults enter freshwater to spawn, they turn bronze and the color further darkens after spawning. Returning to the sea brings back the silver body. They are closely related to the Brown Trout.

Size and Weight

Atlantic Salmon grow to an average of 28 to 30 inches and weigh about 8 to 12 pounds. 

Interesting Facts 

• The Atlantic Salmon is anadromous; they return to freshwater from seawater to spawn. 

• Unlike their Pacific cousins, this fish can breed more than one time in life. 

• Wild salmon is a well-known delicacy, fetching top dollar. A salmon fillet is orange or pink meat with a high nutritional value. 

• Smoltification occurs in juvenile Atlantic salmon. It physiologically prepares them to live in both fresh water and salt water marine habitats. During this time, they also create a homing beacon to help them return to the spawning site. 

• Atlantic salmon live 4 to 6 years. 

Habitat and Distribution

Young Atlantic Salmon are born and spawn in freshwater bodies such as streams, rivers, and lakes. They will stay there 2 to 3 years before migrating towards estuaries and finally into the Atlantic Ocean where they spend 2-3 years feeding, growing before returning to their birth water to spawn. 

Atlantic Salmon United States Distribution Heatmap


In the United States, Atlantic salmon were once native to almost every river and stream north of the Hudson River. Because of habitat destruction and overfishing, most populations in New England sadly have been eradicated. Now, the only native populations of Atlantic salmon in the United States are found in Maine and great lengths are being made to save and populate them.


Spawning occurs from November to January, and the younglings hatch in April. The fish usually spawn at night, at pool ends o
