The brown trout was introduced to North America from Europe in 1883 and has since become a popular quarry for anglers.

The females spawn in autumn and the beginning of winter in a water temperature of about 8 degrees Celsius and lay their eggs in shallow water on gravely bottoms. A nest is dug in the gravel where the eggs are deposited and then covered over. A five- or six-year-old female produces about 2000 eggs per season.

The world record for this fish is 17.8kg and 1.03m in length and taken in Loch Awe, Scotland in 1866.
