Salvelinus profundus (German: Tiefseesaibling 'Deepwater char') is a deepwater char species found only in deep areas of Lake Constance.[2]
This fish can reach 24 cm (9.4 in) in length and has a blunt snout with the mouth in subinferior position. Its lower fins have no white margins and its flanks are silvery to yellowish with pale blue spots; the belly can have a reddish color.[3]
History
Salvelinus profundus was still a commercial species in the 1960s but the
However, the fish species was rediscovered in 2016 during 'Project Lac', a marine survey undertaken by the Swiss Federal Institute of Aquatic Science and Technology.[5][6] The team had not expected to locate the fish, which had not been seen in decades. It is suspected that they were not detected earlier due to the depth at which they swim.
The Lake Neuchâtel deepwater char (Salvelinus neocomensis) is a similar fish species that became extinct in another European lake.[7]
