Recreational catches
Total catches by Russia‘s recreational
fisheries in the Baltic Sea from 1950-
2007 were estimated at approximately
14,800 t (Figure 5). Recreational
catches increased gradually from about
100 t∙year -1 in 1950 to around 225
t∙year -1 by 1980. From 1980 to 2007,
recreational catches continued to
increase steadily, with the highest
levels estimated for 2005 through
2007 at 450 t∙year -1 . Recreational
fisheries are dominated by cod, which
represents nearly 70% of the total
recreational catch, while ‗others‘
represented 20%, herring represented
8% and flatfishes represented 2% of
the total recreational catch (Figure 5,
Table 8). Recreational catches of cod
increased steadily over the study
period from 77 t∙year -1 in 1950 to 310
t∙year -1 in 2007 (Figure 5), and totaled
10,000 t during the study period.
Recreational catches of herring were
minimal, adding only about 1,200 t to
the total catch over the study period,
while recreational catches of sprat
were even lower, totaling only about
20 t from 1950-2007 (Figure 5; Appendix Table B5). Recreational catches of flatfishes increased from 3
t∙year -1 in 1950 to 11 t∙year -1 in 2007, totaling almost 350 t over the 1950-2007 time period. Recreational
catches of salmon were also low, totaling 52 t over the study period.
Total reconstructed catch
The total reconstructed catch for Russia,
which combined ICES landings statistics
with IUU estimates (reporting adjustments,
unreported landings, discards and
recreational catches), was estimated to be
3,739,244 t for the 1950-2007 time period
(Figure 6). Overall, adjustments to landings,
unreported landings, discards and
recreational catches added over 3 million t
to the ICES landings statistics, which were
reported to be about 740,000 t over the
study period (Figure 7). However, these
landings were only for the period 1992-
2007, as ICES did not report landings for
Russia as a separate entity prior to this
period. As ICES landings statistics data for
Russia, specifically, were only available from

1992 onward, the total reconstructed catch was compared to the ICES landings statistics for the period
from 1992-2007. During this period, the total reconstructed catch was 28% higher than the ICES landings
statistics data (Figure 7, Appendix Table B1).
Adjustments to ICES landings contributed the majority of additional landings, representing 71% of the
total reconstructed catch. Other contributions to the total reconstructed catch were discards and
unreported landings representing 5% and 4%, respectively (Appendix Table B1). Recreational catches were
relatively low and contributed only a minor amount (0.4%) to the total reconstructed catch. Discards were
