Tabel 3. Species removed from the HELCOM checklist of fish and lamprey species and the justification. Taxon (Catalog of Fishes) Vernacular name (FishBase) Justification Hexanchus griseus Bluntnose sixgill shark According to HELCOM 2007 also found in Kattegat but according to Swedish records it was found only once in Sweden in Skagerrak, off Måseskär 10 September 1998 and there are no data from Denmark at this point. Cottus koshewnikowi Spiny bullhead Only found in freshwater (T. Kontula pers comm.) Raja montagui Spotted ray According to HELCOM 2007 east of Kattegat (Stehmann & Bürkel in Whitehead et al. 1984) but no records of the species in Denmark and caught only once in Sweden in Skagerrak and in Whietehead et al 1984 it is unclear from the map if is in Skagerrak or Kattegat although text says Baltic Sea. Ciliata septentrionalis Northern rockling According to HELCOM 2007 also in Kattegat but only observed three times in Swedish part of Skagerrak and not caught in Danish waters at all. Lophius budegassa Black-bellied angler No Swedish records and never caught in Danish saltwater. Micrenophrys lilljeborgii Pterycombus brama Norway bullhead Atlantic fanfish According to HELCOM 2007 also in Kattegat and Öresund (Nielsen & Møller 2004) but not present in the updated national checklist and in Sweden latest documented 1923 in Gullmaren & Kosterfjord (Skagerrak) According to HELCOM 2007 also in Kattegat but according to Swedish records only in Skagerark and never for certain caught in Danish saltwater. Taractes asper Rough pomfret According to HELCOM 2007 also found in Kattegat but in Danish and Swedish records no findings have been reported and according to the map in Whiethead et al. 1986 species only occurs in Skagerrak and not in Kattegat or Baltic Sea. Taractichthys longipinnis Big-scale pomfret No Swedish record; Never caught in Danish saltwater Coregonus pallasii Pallas’s houting Treated collectively as Coregonus mareana s.l. Coregonus balticus Baltic houting Treated collectively as Coregonus mareana s.l. Romanogobio albipinnatus Gymnammodytes s emisquamatus Buenia jeffreysi Whitefinned gudgeon Smooth sand-eel Jeffrey’s goby No known occurrences in the HELCOM area, NE in Helcom 2007 According to HELCOM 2007 in Denmark based on Whitehead et al., 1986 but according to Danish records never caught with certainty in Danish saltwater and no records in Sweden. In Whitehead et al 1986 it says whole North Sea coast but not in the Baltic, the map shows both Kattegat & Belt Sea but questionable how accurate the map is. According to HELCOM 2007 occurs also in Kattegat but the species have never registered in Danish waters and in Sweden only caught for sure once in Kosterrännan 1927 in Skagerrak. Acipenser sturio Sturgeon Included in oxyrhincus since the sturgeon occurring in the Baltic after 1800 most probably was not sturio (Gessner & Ritterhoff 2004, Bfn-skripten 101) Clupea harengus membras Spring spawning herring Merged with with Clupea haerengus Osmerus eperlanomarinus Marine smelt Merged with Osmerus eperlanus 18
5. Checklist documentation and distribution data for Baltic Sea breeding bird species The waterbird expert team focussed first on birds breeding in Baltic Sea marine or coastal areas. This resulted in 56 species being included in the checklist for Baltic breeding birds. For one species – the lesser black-backed gull – there are two subspecies in the Baltic Sea area (Larus fuscus fuscus and L. f. intermedius), which have been recorded separately. Thus, 57 taxa occur on the checklist. The number of species found breeding in each area can be found in Figure 12. Denmark Germany / Schleswig- Holstein Germany / Mecklenburg- Western Pomerania Poland Lithuania Latvia Estonia 46 Russia / Kaliningrad 30 Russia / St. Petersburg 45 Finland 50 Sweden 52 0 10 20 30 40 50 60 Figure 12. Number of Baltic Sea breeding bird species per Baltic Sea sub-basin. 5.1 Expert team Chair: Christof Herrmann (Germany) Vladimir Fedorov (Russia), Martti Hario (Finland), Jan Kieckbusch (Germany), Markku Mikkola-Roos (Finland), Lidia Sternik (Poland), Antra Stipniece (Latvia), Ole Thorup (Denmark), Martin Tjernberg (Sweden). 5.2 Taxonomy 32 33 36 The bird taxonomy follows the World Register of Marine Species (WoRMS, www.marinespecies.org November 2011). 31 35 42 5.3 Defining parameters The checklist includes all species breeding in the Baltic Sea area (Figure 12) with a distinct relationship to the marine or coastal environment. Species included in the checklist were required to fulfil the following criteria: a) ‘True’ marine or coastal bird species, i.e. species which breed exclusively at the coast or only exceptionally inland (e.g. sandwich tern Sterna sandvicensis, turnstone Arenaria interpres, eider Somateria mollissima). b) Species which breed mainly at the coast, or reach higher densities, or form larger colonies at the coast compared to inland (e.g., cormorant Phalacrocorax carbo sinensis, white-tailed eagle Haliaeetus albicilla). c) Species which are characteristic inhabitants of typical coastal habitats such as coastal bays, salt meadows, dunes, skerries (e.g., lapwing Vanellus vanellus, meadow pipit Anthus pratensis, northern shoveler Anas clypeata, osprey Pandion haliaetus). Species for which ‘b’ or ‘c’ is true only for some Baltic regions, are included in the checklist. Different subspecies are treated separately. This applies to the two subspecies of the lesser blackbacked gull breeding in the Baltic Sea area (Larus fuscus fuscus and L. f. intermedius), but also to the dunlin (Calidris alpina alpina and C. a. schinzii) and ringed plover (Charadrius hiaticula hiaticula and Ch. h. tundrae). In the latter cases, only the subspecies Calidris alpina schinzii and Charadrius hiaticula hiaticula, respectively, have been included, since the other two subspecies do not breed on the Baltic Sea coast. 5.4 Distribution The reference area for the Baltic Sea breeding bird checklist is the entire territory of the Baltic Sea riparian states (Figure 13). However, for Denmark and Germany / Schleswig-Holstein the coastal zone of the North Sea has been excluded. In the case of Germany, only the Baltic Federal states Schleswig- Holstein and Mecklenburg-Western Pomerania have been considered, and for Russia only the St Petersburg and Kaliningrad regions. 19
