Brown trout spawn in autumn and the beginning of winter, in a water temperature of about 8°C (46°F). Females make nests in gravelly bottoms in shallow water in rivers and streams. The nest is called a redd. They cover the eggs after they lay them. A five- or six-year-old female produces about 2000 eggs per season.

Brown trouts are usually 2.3 to 3.2 kg (5 to 7 lb.), but they can grow much larger. They feed on aquatic and terrestrial insects, crustaceans, molluscs, frogs, salamanders and other fish.

The brown trout was introduced to North America from Europe in 1883. It has also subsequently been introduced to many countries worldwide.

This species is a popular fish with anglers. The best time for fishing for brown trout is in the evening.
