Coregonus macrophthalmus
Coregonus macrophthalmus is a freshwater fish of the family Salmonidae.
The whitefish
Salmonids include salmon, trout, and whitefishes: cold-water fishes with an adipose fin and a strong tie to clean lakes or rivers.
Salmon, trout, and whitefishes of cold, well-oxygenated water.
Range and habitat
It can be found in Lake Constance (Austria, Germany and Switzerland).
GBIF currently lists 115 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Salmonids need cold, oxygenated water and a clean gravel or open-lake feeding ground. Endemic whitefishes collapse when the lake is eutrophied or fished out.
