approximately 12% of the total (Table 14). Germany, Russia and the Baltic States all represented less than
10% of the overall estimate of unreported landings taken from the Baltic Sea between 1950 and 2007.

increased steadily from approximately
35,000 t∙year -1 in 1950 to around 80,000
t∙year -1 in the early 1970s. During the 1980s,
discards fluctuated around 60,000 t∙year -1
before increasing substantially in the 1990s
to a peak of approximately 110,000 t∙year -1
in 1997, before declining to around 85,000
t∙year -1 in 2007 (Figure 4).
The discard total for cod was the
largest by volume, representing
approximately 36% of all discards
between 1950 and 2007 (Figure 4;
Table 15), ranging from a peak of
approximately 43,000 t∙year -1 in
1972 to approximately 15,000
t∙year -1 in 2007. Discards of cod,
herring and sprat totaled
approximately 1.3 million, 1.1
million t and 623,000 t respectively
over the period 1950-2007.
The total estimated discards of all Baltic countries fishing in ICES
subdivisions 22-32 for the period from 1950 to 2007 was approximately
3.8 million t (Figure 4). This estimate included underwater discards of
herring and sprat, ghostfishing, seal-induced discards and boat-based
discards for all countries in all fishing areas. Seal-induced discards are
especially a growing concern to fisheries in some Baltic countries, and
aspects for each discard type are discussed in detail in each country

Discards of cod and herring accounted for 66% of all discards, while
discards of sprat accounted for approximately 16% of our total discard
estimate (Figure 4; Table 15). Starting in the 1990s, however, sprat
appears to have become the major discard species, averaging 26,000
t∙year -1 since 2000 (Figure 4). Discards of flatfishes, salmon and ‗others‘
each accounted for less than 10% of our total discards, but estimated
discards of flatfishes accounted for about 36% of flatfish landings reported
to ICES, Appendix Table B6).
Discards were found to be the largest in Denmark (Table 16). Denmark‘s
discards accounted for approximately 31% (over 1.1 million t) of the total
estimate of discards for the Baltic Sea Large Marine Ecosystem between
1950 and 2007. The total estimates of discards in each of the remaining
countries were less than 600,000 t each when summed over the study
period (1950-2007), and ranged between a minimum of around 68,000 t
in Lithuania, to about 520,000 t in Sweden (Table 16). For countryspecific
details see individual reports (this volume).
