Gennady Yuryevich Zharkov, President of the Noncommercial  Partnership “Russian Salmon” about the catch-and-release principle:

The rivers of Sakhalin Northwest - the only thing in the world the place of simpatry Sakhalin and Siberian taimens.

The Sakhalin Ainu called the Sakhalin taimen of "Chirai", Hokkaido - "Obirame", Nivkhs - "Goy", Japanese - "Ito".

Sakhalin taimen is among very active species of fish making repeated migrations between various water ecosystems.

The important characteristic influencing viability of populations of Sakhalin taimen is the age of maturing and the first spawning of individuals.

Modeling of historical distribution of the Sakhalin taimen is in detail considered in article published in the Transactions of the American Fisheries Society magazine (Fukushima et al., 2011).

It is noticed that the steadiest populations of Sakhalin taimen are dated for river basins with big areas of lakes, lagoons and estuaries.

Scientists have found out that populations even of the neighboring rivers can differ considerably from each other genetically as the taimen in most cases doesn't come into "others" river.

Among animals natural selection in the course of evolution happens on one of two possible scenarios, or strategy.

On all area the Sakhalin taimen has 3 ecological forms:

On the western coast of Sakhalin often you can hear from amateur fishers that here also some "Amur" taimen meets, and it not Red Book Sakhalin and therefore it can be caught.

The most different values of the maximum length and weight of the Sakhalin taimen appear in different papers.

The name Hucho perryi has for a long time got accustomed, some use it still. But how Parahucho has appeared?

As it is known that in the world of nature from the middle of 18th century it is accepted to give binomial names: name of genus and name of species (italics) in Latin, and then a surname of the author and year of first deion.

Sakhalin taimen Parahucho perryi Brevoort, 1856 is described by American ichthyologist James Brevoort in 1856.
