Brown trout habitat

In Freshwater fish

Brown trout

Known by its scientific name as salmo trutta is a freshwater inhabitant, brown trout is a medium-sized fish with a deep golden brown color and a white or cream colored belly. Large dark and red spots surrounded by a clear halo cover his back, fading into small spots along the sides of the body. The tail has very few spots, which distinguishes it from rainbow trout and brook trout that have many spots on the tail.

Brown trout features

Similar in shape to atlantic salmon, brown trout have a fat fin which is the small fin between the rear dorsal fin and the square tail. Although it is of the same species as the sea trout, the brown trout is not migratory like the marine trout.

Brown trout have a highly developed sense of sight and hearing and rows of sharp, pointed teeth. Those sharp teeth give a nod to their carnivorous nature.

1 – Size of the brown trout

In general, these fish grow between 25 centimeters to 38 cm long, but species up to 63 centimeters long have been found.

2 – Weight of the brown trout

The brown trout reaches between 1.80 kilograms to 2.20 kg, species that pass up to 15 kilograms have been found.

3 -Diet

Brown trout have a very broad diet and consume from small invertebrates to small fish. Most of the trout diet consists of small invertebrates, in particular the fly nymphs of the maya and the larvae of caddis fly. The larger marine trouts tend to feed on small fish, especially young herring and sandeels. The lake’s largest trout become almost exclusively fish eaters, following the huge schools of fish found in the huge ice lakes of northern england and scotland.

Habitat of the brown trout

Native to europe, western asia and north-east africa, brown trout was introduced for the first time in north america in the 19th century and can be found in freshwater lakes, fast flowing streams and streams across the united states and canada. They prefer fresh, clean water in the range of 54-67 degrees, but can tolerate water up to 70 degrees.

Reproduction of the brown trout

The spawning habits of brown trout are similar to those of salmon, however, brown trout do not die after they reproduce. The brown trout continue to live in the same general area and reproduce again for several years near the same place. The breeding season begins in october and extends until december.

When the spawning season begins, the fish swim upstream to a point with gravel bottom and moving water. The female makes a saucer-shaped hole in the gravel where she deposits the eggs and the male protects the nest until the female is ready. When ready, the female lays the eggs and the male fertilizes them at the same time. The female covers the eggs with gravel. This process is repeated until the female has laid all of her eggs. A female can lay between 400 and 2,000 eggs depending on its size.

After fertilization, the parents swim back to their native waters. The eggs will remain in the gravel-covered hole during the winter and will be born in the spring. The brown trout takes three to four years to fully mature and has an average life of ten to twelve years. A brown trout and a brook trout will produce a tiger trout.
