  Belonging to Salmoninae of Salmonidae, its scientific name is Salmo trutta. In the United States, it is called German trout, Loch Leven trout or von Behr brown trout. In German it is called Bachforelle. Three subspecies of brown trout are recognized, and two are Salmo trutta fario and Salmo trutta macrostigma. Both are basically land-locked species, and the latter is found only on the island of Sardinia, Italy. Fario has red spots but macrostigma does not, it has only black spots. The third subspecies is Salmo trutta marmoratus (marble trout) and presently it only inhabits the Soca River basin system of Slovenia.
  Brown trout is a European native, and its natural habitat ranges from Europe to Siberia. The "Trout" of Schubert is that trout, and if people in Europe say trout they mean brown trout. "Bachforelle" in German is river trout in English. For many years it has been a beautiful, and beloved target in fly fishing. Although the build resembles that of rainbow trout, it does not have a rainbow-colored lateral band. It has large black spots and red spots that are defined by a pale blue circle. Since the body color turns brown when it grows to 25/cm in body length, it is called brown trout. However, the sea-run type, or fish in a big lake, turn silver.
Apparently a brown trout matures sexually in one to two years after hatching, and its life span is generally from 7 to 12 years, although records exist to show that they live as long as 18 years. It is a trout that grows quite large and the body length often exceeds 1/m. It is an avaricious fish and its ichthyophagy (tendency to prey on fish) is strong. It likes to stay in comparatively slow currents behind rocks or sunken trees.
  Generally it is assumed that brown trout is more difficult to catch than rainbow trout or brook trout. However, in the author's experience, it is basically identical. It is a delicious table fish. Refer to color and XX page.
  The British, in their quest to enhance their fishing enjoyment, transplanted the brown trout from 1863 on into the British colonies in every corner of the earth. Therefore, brown trout now inhabit New Zealand, Australia, India, and the Republic of South Africa. Brown trout were introduced into the United States in 1883. Transplanted to Argentina in 1935, that area turned into a wonderful fishing spot for sea trout. Although the year it was introduced into Japan is uncertain, apparently it was brought to Japan mixed with brook trout eggs in the 1960s.
  Under certain circumstances, brown trout go to sea, become large there, and ascend the river in autumn. They are called sea trout. Their size is usually 1.5-4 kg, but some may reach to 15 kg. Sea trout is also an important target of fly fishing for many years.
