Pacific Salmon vs Atlantic Salmon: Decoding the Differences

When it comes to salmon, there’s an ongoing debate between Pacific salmon and Atlantic salmon. Each type of salmon brings its own unique qualities and flavors to the table. In this blog post, we will delve into the key differences between these salmons, allowing you to make an informed choice the next time you’re at the fish market. So, let’s dive in and explore the battle of Pacific salmon vs Atlantic salmon.

What Are The Main Differences Between Pacific Salmon vs Atlantic Salmon

  • Species Differences: Pacific salmon and Atlantic salmon come from different oceans. As the name suggests, Pacific salmon is found in the Pacific Ocean, while Atlantic salmon is sourced from the Atlantic Ocean. This distinction in their habitats can lead to variations in taste and texture. In terms of species characteristics, Atlantic salmon is more closely related to trout than Pacific salmon.
  • Appearance: When you visit the supermarket, you can easily distinguish between Atlantic and Pacific salmon. Atlantic salmon is light pink, elegant, and delicate in appearance. Its flesh is soft and tender. On the other hand, Pacific salmon has deeper red or orange hues, making a bold statement. The difference in color comes from their diet and habitat.
  • Size: The first thing to note is that Pacific salmon, depending on the species, are generally smaller than their Atlantic counterparts. This size difference is important when planning your cooking methods and portioning.
  • Taste: When it comes to taste, Atlantic salmon has a slightly milder flavor compared to Pacific salmon. It is often described as having a more delicate and subtle taste. On the other hand, Pacific salmon tends to have a more robust flavor with a hint of richness.
  • Texture: Regarding texture, Atlantic salmon generally has firmer meat than Pacific salmon. The flesh of Atlantic salmon is known for being firm and springy, while Pacific salmon tends to have smaller and more tender flakes. This difference in texture can affect the overall eating experience and how the fish holds up during cooking.
  • Nutrition: Both Atlantic and Pacific salmon are rich in nutrients, including omega-3 fatty acids, vitamins, and minerals. They provide a good source of protein. In terms of calories, Atlantic salmon has fewer per serving. However, Pacific salmon may have slightly less fat, making it a suitable choice for those monitoring fat intake.
  • Saturated Fat Content: Atlantic salmon has a higher fat content than Pacific salmon, resulting in a milder flavor and firmer texture. The fat also enhances the taste of dishes. In a 3-ounce serving, cooked Atlantic salmon contains approximately 11 grams of fat, while cooked Pacific salmon contains around 7 grams. If you’re mindful of saturated fat intake, Pacific salmon is a good option.
  • Used For Sushi: Pacific salmon is popular for sushi due to its mild flavor that complements other ingredients well. The abundant supply of fresh and high-quality fish in the Pacific Northwest makes it a great place to try sushi with Pacific salmon. However, wild Pacific coho salmon found in Japanese waters are not used for sushi due to the presence of a parasitic called anisakis, which is not suitable for sushi consumption.
  • Farm Raised Vs. Wild Caught: Pacific salmon, also known as wild salmon, come from the Pacific Ocean and surrounding rivers. They have a robust flavor due to their varied diet, including krill, small fish, and natural food sources. In contrast, Atlantic salmon, or farm-raised salmon, are bred in ocean farms where their diet is controlled and consists of specially formulated feed.
  • Price: Atlantic salmon is generally cheaper than Pacific salmon. You can find Atlantic salmon for $10 to $15 per pound, while Pacific salmon can cost $15 to $25 per pound. If you’re on a budget, go for Atlantic salmon.
  • Lifespan: Pacific salmon, such as the Chinook, Sockeye, and Coho, typically have an average lifespan of three to seven years. On the other hand, their Atlantic counterparts, like the Atlantic salmon, tend to live a bit longer, ranging from five to eight years.
  • Antibiotic Use: When it comes to antibiotic use, Atlantic salmon is more prone to it compared to Pacific salmon. This is primarily because Atlantic salmon are farmed, so their living conditions are heavily controlled.

What is Pacific Salmon?

Pacific salmon refers to a group of five different species of salmon that thrive in the North Pacific waters of the US and Canada: chinook (also called king), coho, pink, sockeye, and chum salmon. These salmon start their lives in freshwater streams, lakes, and rivers before migrating to the sea as small fish called smolts.

After transitioning from fresh to saltwater and growing into adults in the high seas, a biological clock tells the salmon when it’s time to return to the place of their birth to spawn a new generation. The indigenous people of the Pacific Rim rely on salmon as a primary source of protein and regard them as an integral part of their culture.

Salmon also play a crucial role in many economies, with the North Pacific providing the primary source of wild salmon that are commercially harvested and consumed worldwide. The Alaska salmon fishery, which accounts for approximately 90% of wild-caught salmon in North America, is certified by the Marine Stewardship Council.

What is Atlantic Salmon?

The Atlantic salmon (Salmo salar) is a species of ray-finned fish in the Salmonidae family. It is the third largest salmonidae species, behind the Siberian taimen. Atlantic salmon are anadromous, meaning they can live in both fresh and saltwater.

They have a complex life history that starts with spawning and juvenile rearing in rivers. Then, they migrate to saltwater to feed, grow, and mature, before returning to freshwater to spawn. Atlantic salmon are the only salmon species native to the Atlantic Ocean. They are known for their large size, with the average length of mature individuals ranging from 71 to 76 cm (28 to 30 inches) after spending two years in the sea.

Although they used to return in large numbers to major rivers along the northeastern United States, they now only return in small numbers to rivers in central and eastern Maine. Atlantic salmon hold great significance in the Northeast and are commonly referred to as the “King of Fish”.


In conclusion, the Pacific salmon, known for its rich flavor and vibrant color, is highly sought after in the culinary world. On the other hand, the Atlantic salmon, while also delicious, is more commonly found in commercial farming due to its ability to adapt to different environments.

Both varieties have their unique characteristics and benefits. Whether you prefer the taste of the Pacific salmon or the accessibility of the Atlantic salmon, it’s clear that each has its place on the seafood menu.

So, next time you’re dining out or shopping for salmon, keep in mind the distinctions between Pacific salmon vs Atlantic salmon.
