Rainbow Trout

A rainbow trout (Oncorhynchus mykiss) is a species of freshwater fish in the salmon family, known for its iridescent coloring and its popularity as a game fish. They are native to cold-water tributaries of the Pacific Ocean in Asia and North America.

The rainbow trout has a streamlined, torpedo-shaped body. Its most distinctive feature is a broad, pink or reddish stripe that runs along its sides, from the gills to the tail. The back is an olive-green color, and the sides and fins are covered in small black spots. Their name comes from the iridescent sheen on their skin, which can shimmer with a variety of colors.

Rainbow trout are found in cool, clear, and well-oxygenated streams, rivers, and lakes. They are highly adaptable and have been introduced to bodies of water all over the world. They are opportunistic predators that eat a wide range of food, including insects, small crustaceans, and other fish.

Some rainbow trout are anadromous, meaning they live in the ocean and return to freshwater to spawn. This type of rainbow trout is known as a steelhead. Unlike salmon, which die after spawning, rainbow trout can spawn multiple times. They are known for their strong fighting ability when hooked, which makes them a favorite among anglers.
