Brown trout

Brown Trout (Salmo trutta) is a species of salmon native to Europe, but now found worldwide. It is a popular game fish and has been widely introduced into suitable environments globally.

Description

The brown trout is a medium-sized fish, growing to 20 kg or more in some localities, although in many smaller rivers, a mature weight of 1 kg (2 lb) or less is common. The fish has a fleshy adipose fin and a square tail, most often with a red or orange spot at its base. The body is usually brown or golden brown, with darker spots.

Habitat

Brown trout can inhabit various environments. From small, mountain streams to large lakes and the ocean, they have a wide range of habitats. They prefer cooler water temperatures, which is why they are often found in mountain streams and in deeper parts of lakes.

Diet

Brown trout are carnivorous, feeding on a wide variety of organisms. Their diet includes insects, crustaceans, fish and amphibians, and they have been known to eat small mammals and birds.

Reproduction

Brown trout spawn between January and March. The female creates a nest, or "redd", in the gravel of a stream, where she lays her eggs. The male then fertilizes the eggs, and the female covers them with gravel. The eggs hatch in the spring.

Conservation

While brown trout are not currently considered endangered, they are at risk in some areas due to habitat destruction, pollution, and overfishing. Conservation efforts are in place in many areas to protect and restore brown trout populations.
