Wildlife Quiz - Brown Trout

The Brown Trout by Steve Vose

The Brown Trout (Salmo trutta), also known as German Brown Trout, Brownie, Loch Leven Trout and Saibling, exists as a game fish native to Europe but stocked throughout South America, North America, New Zealand, Australia and many other countries. The Brown Trout was first introduced into the United States in 1884 when they were released into the Baldwin River in Michigan.

Brown Trout possess light brown coloration with pronounced black spots on the back, sides and head. These black spots are ringed with a red halo. Red spots also exist all along its sides.

In Maine, Brown Trout tend to thrive in lakes, ponds and streams that would kill Brook Trout and Salmon. Because of this Inland Fisheries and Wildlife is looking at the Brown Trout to support a viable sport fishery of the future in “marginal” waters. 

Brown Trout can grow to huge sizes depending on habitat. In a small ponds, for example, a 16-inch brown is considered big, while in large lakes they can weigh 10-20 lbs depending on available feed. In Maine, the normal size for a Brown Trout is 14-20 inches and 1-2 pounds. Maine Brown Tout will occasionally reach 10 pounds.

Young Brown Trout survive on a diet of aquatic and terrestrial insects, but browns larger than 12 inches feed primarily on large prey such as other fish, crawfish and even mice. Big Brown Trout also move very little during the day light, instead preferring to hunt for food primarily at night. Scientists tracking the movements of big Brown Trout have determined that during day light hours big Brown Trout barely move from their protective hiding places but at night they will travel miles in search of food.  

Brown Trout spawn in the fall. Young Brown Trout (fry) emerge from the eggs early in the spring and immediately begin searching for food. If able to successfully avoid predators, Brown Trout may live to exceed 20 years.
