Natural History

The Brown Trout’s native range extends from northern Norway to North Africa. The first batch of Brown Trout eggs were distributed to several U.S. hatcheries in 1883, they were then introduced into many suitable waters across the U.S. between 1884 and 1890. Those introductions have created viable self-sustaining fisheries throughout the country. They spawn in late fall to early winter with the redd built in gravelly bottom, shallow water of rivers and streams.

Fun Facts

A 5-6 year old female will lay about 2000 eggs each spawn.
