The analyses include 10 fleet segments that all have their main fishing ground in the eastern Baltic Sea and covered 93% of
the total landed value of Atlantic cod (Gadus morhua), European sprat (Sprattus sprattus) and Atlantic herring (Clupea harengus)
in the eastern Baltic Sea in 2011. The Fleet segments are mainly selected based on the length groups, but also the gear type
and the fishing region are used to define the segments. To keep the analyses to a relatively small number of segments, the
8 EU countries that surround the Baltic Sea are divided into 4 regions: (i) DEU/POL, (ii) DNK/SWE, (iii) LTU/LVA and (iv) EST/
LVA, where each region is expected to have a similar fleet cost structure, but where differences in cost structure between the
four regions may be significant due to historical, regulatory or social reasons. An overview of the main technical and economic
characteristics of the 10 fleet segments is provided in Table 1. The fleet segments with the most sea days per year
is the passive gears 0–12 m and they amount for 64% of the total sea days, but only 10% of the catch value. In comparison
does the trawlers 24–40 m amount to 17% of the sea days, but 55% of the landings value
