Sea trout refers to several species of fish that inhabit coastal waters and estuaries. They are commonly found in the North Atlantic and are known for their silvery skin and distinctive spots. Sea trout are often sought after by anglers due to their fighting ability and delicious taste. These fish typically migrate between freshwater rivers and saltwater environments, making them anadromous. They feed on smaller fish, crustaceans, and insects, which contribute to their growth and flavor. Salmon and char are related species that share similar habitats and behaviors, making them part of the same family of fish.
