Trout is a widespread representative of salmonids, present in our waters as a result of artificial population or by Escape from ponds, by their feeding waters or along with the drainage waters in the pools.

Trout

The Trout is a freshwater fish, originating from the mountainous and hilly regions of Europe, but now found worldwide, thanks to its ability to adapt to different aquatic environments. The main species of trout is Salmo trutta, but there are also other species, such as Salvelinus fontinalis and Oncorhynchus mykiss, which are frequently bred in fish ponds.

Trout is a medium-sized fish, reaching a length of about 30-70 centimeters, depending on the species. It is known for its vibrant and shiny skin colors, ranging from silver shades to tones of green and blue. This attractive coloring makes trout a popular fish among both fishermen and the gastronomy industry.

These fish prefer clean and cold waters, such as mountain rivers and streams. They can meet their nutritional needs from natural sources - such as insects, worms, and various species of crustaceans - as well as from supplementary food obtained in fish ponds. Trout is an active and intelligent predator, using fast and efficient hunting techniques to catch its food.

Trout reproduces through anadromous breeding, meaning it spends a significant part of its life in the sea and returns to freshwater to reproduce. During the breeding season, females deposit eggs in special nests called redds, on the bottom of sandy or gravel areas in rivers and streams. The eggs are then covered with sand or gravel to protect them and keep them moist. After hatching, the larvae are fed with reserves in their bodies until they are able to find food on their own.

Due to the high demand for this fish in the gastronomy industry, trout is intensively bred in modern aquaculture systems, which provide optimal living conditions and rapid and controlled growth. In such fish ponds, trout are fed a specialized diet that ensures an adequate intake of nutrients and healthy development. This way, the growth process can be controlled and optimized to achieve desired sizes and weights.

Trout is also appreciated in the kitchen for its tasty and healthy meat, which contains a high amount of proteins, Omega-3 fatty acids, and vitamins such as vitamin A and D. This meat is considered very valuable and is consumed and appreciated in various culinary preparations, whether it's roasted, smoked products, or sushi.

However, although trout is a prized and popular fish, there are also challenges in terms of conserving and managing wild populations. Overfishing, water pollution, and destruction of natural habitats are significant threats to the survival of this fish. Therefore, it is essential to implement protection and conservation measures to ensure that trout remains a precious part of aquatic ecosystems and our natural heritage.

In conclusion, trout is a fascinating fish with an impressive adaptability to different aquatic environments. From its colorful beauty to its delicious taste, trout holds a special place in our hearts and kitchens. However, it is important to be aware of the need to conserve and protect this species in order to enjoy it and pass it on to future generations.

Facts

Origin

It is bred with great success in industrial farms on the continent, being sold then on the market, as a product highly demanded especially by the big restaurants.

In our country, this fish is not found in many natural streams, but it grows with great success in ponds.

It is present in the following rivers and lakes in our country: Tibles Valley, Minis and Nera, varghis, Cormos and Casinul, Slanic, Teleajen, Azuga, Red Lake, Campul Cetatii, Niraj, Vida, Crisul Negru, Finis, Vascau, Somesul Rece, Jiu, Bistrita Aur, Lotru, Trotus, Putna, Slanic waters, Brodina, Sucevita, firiza Creek etc.

Trout Feed

The meat of the trout from the mountain rivers is identical in taste to that of the indigenous trout, rainbow trout grown in ponds have an inferior taste, due to the forage consumed. Their meat is slightly fatter than that of Indigenous Trout.

The food of the lake trout is very varied, from small insects and larvae (even adult specimens, a few kg can be seen frequently biting), small crustaceans, mollusks, racusori, salamanders, frogs, mice or even waterfowl but pupa age of 1 year the basis of food is made up of fish, greens (craeti) and zglavoace.

Very often the meat of wild lake trout has a pinkish or even orange color, the same as that of salmon. This Color is given by natural food, it seems to come from small crustaceans very hunted by Trout.

In consumer, farmed Trout, the color is given by a substation introduced into the feed. It's about astaxanthin or Pink Carophill, a synthetic vitamin that prints a protocol color to fish meat.

Features Trout

The body, with a flattened spindle shape, is slightly wider and the scales somewhat larger than those of the indigenous Trout. The muscles are equally developed, which is vital to move freely in the fast mountain waters. The teeth, strong, are placed similar to the native trout. On the back can be distinguished adipose dorsal characteristic of salmonids.

The essential differences between the two species of trout appear in the most obvious way in color. The hindwings of rainbow trout are bluish-grey, sometimes with lilac hues. The sides are shiny silver, the belly is white.

On the body are distinguished several small unedged spots with white. From the opercula to the caudal, on both sides stretches a reddish-pearlescent stripe, which plays in the shades of the rainbow, hence the name of the fish (near the Red Stripe can sometimes be seen blue or greenish stripes).

The pace of development of Trout is faster. It develops extremely quickly in conditions of breeding, where it capitalizes with efficiency the feed but especially the food from slaughterhouses. It is not as picky in terms of water temperature and its oxygen content, it can also be found at lower altitudes, namely in the preferred regions of grayling or toothpick.

It is known that at these lower altitudes the water is warmer, sometimes more cloudy and with a lower dissolved oxygen content than that of the upper courses (between the mountains) of the rivers. In natural waters, Trout's favorite places are around stones, various larger objects (bridge legs, poles, etc.) in the water, under the washed banks of rivers.

If the water does not bring him sufficient food, he leaves these places, moving on to hunting.

Trout Breeding

The breeding of rainbow trout shows a characteristic, namely that it reproduces in the spring, unlike the indigenous trout, which reproduces in the fall.

The fact that rainbow trout spawns in February-April favors its artificial reproduction. The female lays about 20000-50000 eggs with a diameter of 4-5.5 mm.

Because in Romania most of the lakes populated with lake trout are Dam lakes where the water level fluctuates sometimes by tens of meters are very rare cases when the tips deposited over the fall get to hatch, most of the time they remain on land or being clogged by too much water which leads to the killing of embryos in spawning.
