Trout habitat and lifestyle
According to the habitat, sea and river trout are distinguished. The main difference between them is the size and color of the meat. Sea trout are large fish with dark red meat. It lives in small numbers along the Pacific Ocean in North America. As mentioned earlier, it is distinguished by its large size.
River trout includes all types of freshwater fish of this family. A favorite habitat is mountain rivers, so there are a lot of this fish in Norway. River fish trout prefers only clean and cool water. It can often be found in lakes. This fish is widespread in many reservoirs of the Baltic states, as well as rivers that flow into the Black Sea.
Prefers to keep to the mouths of rivers, rapids, as well as areas near bridges. In mountain rivers, he likes to stop in the area of whirlpools and mountain rapids. Of the lakes, it prefers deep-water ones and often rests on the bottom.
Red fish trout prefers rocky bottom. In danger, it begins to hide under stones and tree roots. In hot weather, trout can even be found near clean springs and springs.
The lifestyle of the brown trout trout is well researched, due to the fact that this fish is excellent for fishing and breeding. After spawning (during the winter season), the fish swims downstream and, as a rule, ends up near springs and at great depths. It will be quite difficult to meet her on the surface of the river at this time.
Nutrition and breeding of trout
Spawning is the most interesting period in life fish of the salmon family - trout. During spawning, fish can be seen on the surface of the reservoir in which it lives. She will splash and swim at an extraordinary speed quickly.
These mating games take place on the surface of the river. After them, the youngest individuals will return to their usual habitats, and the rest will remain in the river to increase the population of their species. The fecundity of female trout is not great. Maturity in trout occurs already in the third year of life.
The larvae hatch from the laid eggs in early spring. At first, they do not move, but remain in their pouch, from which they feed. And only after a month and a half the fry begin to gradually get out of the shelter.
During this period they feed on the larvae of small insects. From this moment on, the trout begin to grow very quickly and actively, and in a year they become more than 12 centimeters in length. The growth rate of the fry depends on the body of water in which it is located.
The larger the pond - the more food for trout in it - the faster it will grow. In small streams you will not find a big fish, it basically reaches a size of 15-17 centimeters.
What kind of fish is trout? The answer is simple! Trout - predatory fish. The food for the river variety of this fish is crustaceans, mollusks, insects and their larvae, as well as small fish. Trout prefers to feed 2 times a day: early in the morning and in the evening.

If you decide to breed trout, you should understand that simply organizing a pond for such fish is not enough. Judging by photo, size of fish - trout directly dependent on water.
If you breed this species in sea water, then the individuals will grow quickly and will be large, if the water is fresh, then the fish will be small. The water in the reservoir should always be clean and cold. Never use chlorinated water. Chlorine is poison for trout.
It is advised to breed trout in cages - a metal floating frame that is attached to the shore. You can place cages in any ready-made reservoir: a river, a pond. Trout is launched in the amount of 500-1000 individuals.
Trout do not breed in ponds, so a broodstock is launched there. You need to feed the fish with natural food (at least 50%). Fry and young must be kept separate from large fish, otherwise they can be eaten.
