Are Pacific Salmon Always Larger?

While Pacific salmon are generally larger, there are some exceptions. For instance, while the Atlantic salmon may not be as large as every Pacific species, they certainly hold their own and are usually larger than pink and sockeye salmon.

Comparing with Other Salmon Species

In other parts of the world, especially in Siberia, you might encounter the Taimen, a truly massive salmon species. The Taimen, also known as the Siberian salmon, can grow up to 6 feet long and weigh up to 170 pounds. However, due to their popularity among anglers, they rarely reach such large sizes in the wild. These siberian salmon are known for their predatory nature and even historical records suggest that they occasionally preyed on land animals, making them a formidable adversary.
