In addition to the countries listed above, Oncorhynchus mykiss is also used in Ethiopia, Lesotho, Malawi, Afghanistan, Armenia, Eswatini, Kazakhstan, Kyrgyzstan, Nepal, Austria, Hungary, Liechtenstein, Luxembourg, Romania, Serbia, Slovakia, Switzerland, Zimbabwe, Uganda, Hungary, and Uzbekistan, although rainbow trout are not considered native to all of these locations; they were introduced by humans due to their characteristics, such as very rapid growth.
Rainbow trout are used as sport fish for recreational anglers in lakes and rivers and are an important food source for humans in commercial fisheries.
It is served fried, boiled, steamed, and smoked and is enjoying growing popularity, although it is sometimes considered a pest.
There are two different populations: anadromous populations, which occur in coastal rivers, and the other are sedentary populations that now inhabit small headwater streams, large rivers, (unfrozen) lakes or reservoirs, often in cool, clear lakes and cool, fast-flowing streams with mud-free bottoms. In streams, deep, slow-flowing pools are important wintering habitats.
Oncorhynchus mykiss is a resident of clear, cold headwaters, streams, small to large rivers, lakes, and tidal zones and is found in almost all waters such as lakes, rivers, and streams, but generally not in waters with summer temperatures above 25 °C or in ponds with very low oxygen concentrations.
Trout feed on a variety of aquatic and terrestrial invertebrates and small fish.
Adult fish undertake short spawning migrations. Anadromous and lake forms can travel long distances to spawning streams.
Colouring:
Oncorhynchus mykiss has a striking colouring, with a silvery or light golden body with small black spots and black spots on the dorsal and caudal fins.
The adipose fin has a black edge and spots.
A broad, iridescent purple-mauve band runs from the head to the caudal fin, giving rise to the name “rainbow trout.”
Older males tend to become darker, while juveniles have about 10 broad dark gray vertical stripes along the body.
In order to achieve larger size and more meat, the genome of trout living in aquaculture has been modified to produce so-called “triploid rainbow trout,” a variant in which the freshly fertilized eggs are subjected to heat or pressure shock treatment to produce a triple set of chromosomes instead of the normal double set.
The advantage of these sterile trout, which are no longer capable of reproducing, is that they continue to eat during the reproductive period and the food is not used for the formation of germ cells, but is reflected in growth in size and length.
However, these genetically modified fish are more sensitive to various environmental factors.
The English name “steelhead” derives from the gray-blue color of the trout's head, which is reminiscent of steel.
