A question that is often asked by newcomers to the world of fly fishing and people interested in trout, In general, these fish have scales. The easy answer is that yes, this species of fish has scales and a good amount of them go through its body and skin.
Other species that also have scales are brown, rainbow, brook, and lake trout.
Usually, the scales are incredibly tiny and may be barely noticeable at first. If you pass your hands over a rabbit in one direction through its body it feels soft to the touch, however, in case you pass your hands in another direction, you can really feel the roughness and this is really the scales around the fish.
DO TROUT HAVE SCALES AND FINS?
Also as with scales, trout have fins, these fins are employed to get a couple of things but generally speaking, they allow the fish to move through the cold water and float to permit the fish to keep in 1 place.
Maybe as soon as the current of this river they’re in is forcing them in 1 direction but in actuality, they wish to sit and not go. Having fins lets them hold themselves in 1 place and remain wherever they are.
Trout usually enjoy doing this when they’re feeding on prey that’s passing in a present.
A very singular characteristic of the trouts is that they vary of tonality according to the age, species, and state of mind. Most of them have a band of color on their sides which, in the case of the common trout, is golden. It can also be distinguished by the yellow tone of its belly, and some red and greenish spots, wrapped in white rings, which spread all over its body. With the light of the sun, it radiates luminosity.
It is an elongated fish, with a rounded tail and smooth scales. Its mouth is so large, that it extends to the lower part of the eyes. The robustness of its head is very unique.
The trout is corpulent. It can reach 15 kilograms in weight and measure from 25 to 90 centimeters. The most developed ones are those that live in mountains and plain rivers.
THE BEST KNOWN TROUT
There are many varieties of trout. The rainbow trout, for example, is very similar to the common trout. It is bluish-green, dark on the back and white on the belly. Its streaks are black and its flanks are orange or reddish. It is seen in North America, Europe, and South America. It does not usually exceed 40 centimeters.
The lake trout reaches greater dimensions; usually one and a half meters. The lakes of the pre-alpine zone and the Alps are their natural habitat.
Very similar to the salmon is the sea trout or prisoner. Species of up to 20 kilos have been caught in the Atlantic and the Baltic Sea.
In the United States and Europe is very common to find the cut-throat trout, named for the long line that forms in that part of its skeleton. In these same places, the so-called Golden Trout also proliferates, whose body reflects particular golden flashes.
The trout’s diet is autophagic because it is based on a diversity of products, both aquatic and terrestrial. It is a very skillful fish and adapts to changes. In its wildlife, it eats fish, crustaceans or insects. Anything that moves and is within reach can be “appetizing” to them: frogs, worms, crabs, tadpoles, shrews, water mice, and even smaller trout.
There are several methods of hunting. Sometimes she positions herself close to the surface and jumps up to hunt in the air, but other times she stands still waiting for some animal to be dragged away by the current so that she can devour it.
If it is in captivity, it is provided with agglomerates of fishmeal, natural pigments and other compounds containing vitamins and minerals.
REPRODUCTION AND MORE
The average life span of a trout is 8 to 10 years if it manages to escape from the fishermen who are looking for it for human consumption. It is one of the most sought-after fish due to its multiple benefits. It helps to lose weight and to regulate the blood pressure.
The reproduction of the trout takes place between January and March, and it is very limited. The males of this species look for space where the female will spawn, and where several of them will place their sperm.
The incubation process lasts 40 days, but after that time the adults move away without giving any kind of protection to the eggs. Therefore, although the female may lay about 10,000 eggs, only four may reproduce.
Trout tend to migrate to reproduce, but always moving in freshwater, very different from other fish like salmon, which move from the sea to the river.
