Baltic trout populations have low density in the
rivers that flow from Finland to Russia and meet the Gulf of Finland of the
Baltic Sea because of lack of suitable habitats and pressure of illegal
fishing. Trout (Salmo trutta Linnaeus, 1758) is included into the Red Data Book
of Russian Federation as rare species considering protection and the only one
trout population with wild, natural origin was found in the transboundary
rivers Tchornaja and Malinovka.

During the period 2011-2014 Russia and Finland
have been carrying out joint project “Rivers and fish – our common interest”.
The goal of the project is restoration of populations of valuable salmonid fish
species (trout and salmon) and creation of favorable conditions for its
habitats in transboundary rivers. The project contained ichthyologic research,
release of individually marked salmon juveniles in the rivers, restoration of
rapids (as spawning grounds) and removing of obstacles to the passage of fish
in the rivers in Finland and Russia. Besides, other goal of the project was to
promote local and cross-border nature protection by establishment of protected
areas (PAs) along the riversides in both countries.

In the frame of project few
local PAs have been created on the river Malinovka in Finland and one Nature Reserve
“Salmon rivers of Vyborg bay” have been proposed to organize on the Russian
part of this river. This PA will provide more effective protection of trout
populations in the rivers by prevention of illegal fishing and timber
harvesting in the area. In addition PA should provide conservation of areas
with valuable old-growth spruce and aspen forests and habitats of endangered
species of fauna and flora. Nowadays establishment of the PA Nature Reserve
“Salmon rivers of Vyborg bay” has a priority status in the Scheme of
territorial planning of Leningrad region, Russia, that means it should be
organizing before 2016.
