state that there had been no facts confirming the alleged increase in the Belukha
whale population in the northern seas. Besides, the Belukha whale does not feed
on cod and therefore cannot upset its abundance. If some of whale species really
did increase in number, that should be Polosatik whale inhibiting the Atlantic. But
there locates the international reserve where even scientific research whaling pro-
hibited.
Today, 15 years since the declaration of the International Moratorium on any
commercial catching of sea mammals (the ex-Soviet Union joined the Morato-
rium in 1987), populations of the largest and valuable Greenland Whales is short
of 2000, while gray whales, according to domestic and international estimations,
are slightly over 12000.
What drives the statesmen and interdepartmental science who ever more in-
tensively push the idea of resumed whaling? Everyone knows that this country
neither means nor qualified personnel to accomplish this.
Volcanoes and Fish
Kamchatka is the land of volcanoes. Their periodic eruptions with throwing
out big quantities of volcanic ash sometimes seriously affect the dynamic of Red
salmon population. Correlation has been observed between volcanic ash falling
over the Red salmon lakes and increase in fish return for spawning. A number of
investigations carried out in Alaska proved this correlation and suggested that
the effect was caused by artificial fertilization. Positive effect of ash falling on
population dynamics of any other salmon species has not been proved so far.
According to experts, growth of Red salmon stock in the Azabachye lake after
eruption of Bezymyanny volcano in 1956 was minimum 5,9 times and maxi-
mum 10,3 times and after eruption of Tolbachik volcano in 1975 average growth
was 3,5 times and maximum 4,5 times. Comparison was done to 14 generations
of fish never coming to the fertilized lake.
It is early to make a conclusion on the effect of fertilization of the Aza-
bachye lake in 1990 afer eruption of the volcano Klychevskayay Sopka (not all
generations of Red salmon have come back). But it was after this eruption that
for the first time during the last 50 years Red salmon harvest in the Kamchatka
river made 5 092 tons in 1995 and 6 400 tons in 1996 (average annual harvest
in 1977–1994 made 2200 tons). Increase in Red salmon harvest mainly resulted
from big catch in the Azabachye lake . At present scientific information is
available proving positive effect of natural fertilization on Red salmon stock
in Kurilskoye lake (area – 77 square km, average depth – 195,2 m), located in
the basin of the Ozernaya river. In april 1981, the lake was fertilized with vol-
canic ash during eruption of Alaid volcano.
