The first key difference lies in their origins. Atlantic salmon (Salmo salar) is exclusively found in the Atlantic Ocean. Conversely, Pacific salmon comprises several distinct species, all inhabiting the Pacific Ocean. This geographical separation contributes significantly to their contrasting characteristics.
Atlantic Salmon: The Singular Species
Atlantic salmon is a single species, Salmo salar, meaning “leaping salmon” in Latin. This refers to their impressive ability to leap over waterfalls during their upstream migration to spawn. Historically abundant, wild Atlantic salmon populations have declined significantly due to overfishing, habitat loss, and pollution. Today, the majority of Atlantic salmon available in the market is farmed.
Pacific Salmon: A Diverse Family
Pacific salmon encompasses several species, each with unique traits:
-
Chinook (Oncorhynchus tschawytscha): Also known as King salmon, it is the largest and often considered the richest in flavor.
-
Sockeye (Oncorhynchus nerka): Known for its deep red color and robust flavor.
-
Coho (Oncorhynchus kisutch): A milder-flavored salmon with a bright red flesh.
-
Pink (Oncorhynchus gorbuscha): The smallest and most abundant Pacific salmon, often canned.
-
Chum (Oncorhynchus keta): Also known as Keta salmon, it has a milder flavor and is often used in smoked salmon products.
This variety provides a spectrum of flavors, textures, and nutritional profiles within the Pacific salmon family.
