Total marine fisheries extractions by country in the Baltic Sea

Catch ( t x 10 5 )
Total marine fisheries extractions by country in the Baltic Sea: 1950-present, Rossing, Booth and Zeller 19
cod, and negative adjustments ranging from – 88,096 t to -183 t were
added to our remaining taxa (Table 11).
Over the entire period of study (1950-2007), adjustments added to
reported landings for Latvia, Russia and Estonia combined
represented 80% of the adjustments made for all countries (Table 12).
The majority of these adjustments were added to these countries prior
to 1990 (see country specific reports) and illustrates our preference for
adjustments to reflect purely country specific catch accounting
preferences. The remaining countries‘ adjustments contributed the
remaining 15% of the total adjustments made to all countries (Table
12). Finland, Sweden and Denmark all had net negative adjustments
added to ICES landings statistics between 1950 and 2007 (Table 12).
Overall, Denmark received the smallest magnitude of adjustments to
reported landings (Table 12).

Unreported landings totaled approximately 5.7 million t between 1950 and 2007 for all taxa and all
countries fishing in the Baltic Sea LME (Figure 3). Estimated unreported landings increased slowly from
approximately 9,000 t∙year -1 in 1950, to
approximately 50,000 t∙year -1 in the late
1970s. During the 1980s they increased
to approximately 110,000 t∙year -1 , before
increasing to approximately 350,000
t∙year -1 in 1996-1997. Unreported
landings apparently declined steadily
since then, reaching approximately
155,000 t∙year -1 in 2007 (Figure 3).
Cod had the greatest amount of
unreported landings, totaling about 2.3
million t over the period of study (1950-
2007; Table 13). By the 2000s (2000-
2007) unreported landings of cod
averaged 66,000 t∙year -1 (Figure 3). The
total unreported landings
of cod (1950-2007) were
about 18% greater than
those of herring, which
had the second greatest
volume of unreported
landings (Table 13). By the
2000s unreported
landings of herring and
sprat were on average
62,000 t∙year -1 and 52,000

Unreported landings of all species peaked in the 1990s, with those of cod and herring being the most
signficiant (Table 13). The only species whose estimates of unreported landings remained quite stable
between 1950 and 2007 were those of salmon (Table 13).
For the entire period, unreported landings were greatest in Poland, Denmark, and Sweden (Table 14). For
country-specific data, see individual country reports (this volume). Each of these countries had unreported
landings that totaled more than 1 million t over the period of study (Table 14), with Poland having the
greatest amount of unreported landings totaling approximately 1.7 million t, or 29% of the total
unreported landings of all Baltic countries between 1950 and 2007. The total unreported landings of
Finland were representative of the mean proportion of unreported landings Baltic-wide, with
