Basic tasks:
-to reveal features of changes in
species composition and stock
abundance for pelagic fishes off
Sakhalin Island during the first
decade of the 21 century;
-to reveal trends of long-term
changes in abundance for
common pelagic fishes in the
Tatar Strait and south-western
part of the Okhotsk Sea in 1950-
2010;
to reveal occurrence (absence)
of conjugation of the long-term
changes in climatic and
oceanological factors and fish
abundances;
Data Sources:
1.Catch statistics: 1950-2009 for 10
marine fish species, including pink
salmon.
2. Data from trawl surveys (1976-2009),
ichthyoplankton (1968-2011) and eggs
surveys (1988-2010).
3. Long-term assessment of herring and
walleye pollock abundance, using VPA
and SCAP (stochastique cohort analyses
of processes) methods correspondently.
4.Oceanographic data: water temperature
at south-western Sakhalin (1924-1999),
western Hokkaido (1964-2003); Ice
conditions in the Okhotsk Sea (1930-
2007).
5. Climatic indices: PDO, SHI, SOI, AOI,
MOI - 1950 -2004.View entire presentation
