Rainbow trout

Rainbow trout (Oncorhynchus mykiss) is a species of trout and a member of the salmon family. It is native to the cold-water tributaries of the Pacific Ocean in Asia and North America. The rainbow trout has been introduced to other environments worldwide.

Description

Rainbow trout are a silver color with a pinkish band along their sides, small black spots on their back, and a white underbelly. The average length is 20 to 30 inches. They are known for their beautiful, vibrant colors that shimmer in the sunlight, hence the name "rainbow" trout.

Habitat

Rainbow trout are found in a wide range of habitats, but they prefer cold, clear streams and lakes. They are native to the tributaries of the Pacific Ocean in North America and Asia, but they have been introduced to waters all over the world.

Diet

Rainbow trout are carnivorous. Their diet primarily consists of small invertebrates, but they will also eat fish eggs and small fish.

Reproduction

Rainbow trout spawn in the spring. The female creates a nest, or "redd," in a stream bed where she lays her eggs. The male then fertilizes the eggs, and the female covers them with gravel. The eggs hatch in about four to seven weeks.

Conservation

Rainbow trout populations are currently stable, but they face threats from habitat loss and pollution. They are also a popular target for recreational fishing, which can lead to overfishing.
