Introduction to Whitefish and Salmon

What Are Whitefish?

Whitefish is a term that refers to a group of fish with mild-flavored, white-colored flesh. These fish are typically found in freshwater and cold marine environments. Common species classified as whitefish include cod, haddock, pollock, and even certain types of freshwater trout.

Key Characteristics of Whitefish

  • Color and Texture: White, flaky flesh with a mild taste.
  • Diet: Feeds on smaller fish, plankton, and aquatic invertebrates.
  • Common Varieties: Cod, halibut, and sole.
  • Habitat: Often found in colder waters, particularly in the Atlantic and Arctic oceans.

What Is Salmon?

Salmon, on the other hand, is a type of oily fish primarily known for its vibrant orange or pink flesh. It belongs to the family Salmonidae, which also includes trout, char, and grayling. Unlike whitefish, salmon are anadromous, meaning they migrate between freshwater and saltwater throughout their life cycle.

Types of Salmon

  1. Atlantic Salmon: Found in the Atlantic Ocean, now mostly farmed.
