Brown trout in Japan
In recent years, the natural breeding area of brown trout has spread rapidly in about 10 years and the survey can not be made in time.
In “Nagano” where I live, Brown trout grows naturally in the mainstream of each river
It is still rare at mountain streams where the but it is problematic as to how it will become in the future
From the viewpoint of the fishermen, the expansion of the habitat and the expansion of the habitat seem to be very intense than the research institution’s presentation.

Brown trout also increased in my fishing ground
They grow to large size, average about 45 - 50 cm
I have caught 70 centimeters or more
It is a pleasant thing to do as an angler but it is a difficult problem
