Editing Lake Constance (section)

==== Fish ====
Around 45 species of fish live in Lake Constance. The annual haul from fishing is 1.5 million kg. Unusual species occurring here considering the location of the lake are the [[Coregonus|whitefish]] (''Coregonus'' spec.) and the [[Arctic char]] (''Salvelinus alpinus''). Fish that are important for the fishing industry are:
* [[Bodenseefelchen]] (German: also ''Blaufelchen'', Lat.: ''Coregonus wartmanni'')
* [[Sandfelchen]] (German: also ''Weißfelchen'', Lat.: ''Coregonus arenicolus'')
* [[Gangfisch]] (Lat.: ''Coregonus macrophthalmus'')
* [[Lake Constance whitefish]] (German: ''Kilch'', Lat.: ''Coregonus gutturosus'')
* [[Thymallus thymallus|Grayling]] (German: ''Äsche'', Lat.: ''Thymallus thymallus'')
* [[European perch|Perch]] (German: ''Flussbarsch, Kretzer, Barschling,'' Swiss German: ''Egli'', Lat.: ''Perca fluviatilis'')
* [[Common bream|Bream]] (German: ''Brachse'', ''Brasse'', Lat.: ''Abramis brama'')
* [[Northern pike]] (German: ''Hecht'' (Lat.: ''Esox lucius'')
* [[Zander]] (Lat.: ''Sander lucioperca'')
* [[Burbot]] (German: ''Quappe'', ''Trüsche'', Lat.: ''Lota lota'')<ref>Source: Who is Who Bodensee 2010/2011 Südkurier GmbH Medienhaus</ref>
* [[European eel|Eel]] (German: ''Aal'', Lat.: ''Anguilla anguilla'')
* [[European bullhead|Bullhead]] (German: ''Groppe'', Lat.: ''Cottus gobio'')
* [[Tench]] (German: ''Schleie'', Lat.: ''Tinca tinca'')
* [[Wels catfish]] (German: ''Wels'', Lat.: ''Silurus glanis'')
* [[Salmo trutta lacustris|Lake trout]] (German: ''Seeforelle'', Lat.: ''Salmo trutta lacustris'')

The Bodenseefelchen (''Coregonus wartmanni''), which was named after Lake Constance due to the great numbers found there, is often prepared whole or as a fillet, in the style of the miller's wife (''nach Müllerin Art''), in local fish restaurants in a similar way to other trout<ref name="Fische">Themenpark Umwelt des Umweltministeriums Baden-Württemberg – BodenseeWeb: [http://www.themenpark-umwelt.baden-wuerttemberg.de/servlet/is/16094/?path=4422;&partId=0&part=15854 Fische]</ref> It is also often served smoked.

Two [[endemism|endemic]] species are known to have existed only in Lake Constance, the [[Bodensee-Kilch]] (''Coregonus gutturosus'') and [[deepwater char]] (''Salvelinus profundus''). The former is now assumed to be extinct, while the latter was feared extinct for decades until its rediscovery in the 2010s.<ref>Information board at the harbour in [[Ludwigshafen am Bodensee|Ludwigshafen]] about especially prized Lake Constance fish.</ref><ref>{{Cite journal|last1=Doenz|first1=Carmela J.|last2=Seehausen|first2=Ole|date=2020|title=Rediscovery of a presumed extinct species, Salvelinus profundus, after re-oligotrophication|url=https://onlinelibrary.wiley.com/doi/abs/10.1002/ecy.3065|journal=Ecology|language=en|volume=101|issue=8|pages=e03065|doi=10.1002/ecy.3065|pmid=32274790|bibcode=2020Ecol..101E3065D |s2cid=215726746|issn=1939-9170}}</ref>
