The brown trout is a species of freshwater fish native to Europe, but it has been introduced to many other regions, including North America and New Zealand. It is known for its distinctive brown spots on a golden to olive-brown body, which helps it blend into its natural habitat. Brown trout prefer cold, clean waters and are often found in rivers, streams, and lakes. This fish is a popular target for anglers due to its challenging nature and delicious taste. Brown trout can grow to significant sizes, with some individuals exceeding 30 inches in length. They are opportunistic feeders, consuming insects, small fish, and crustaceans.
