|Scientific Name:||Knipowitschia mermere|
|Species Authority:||Ahnelt, 1995|

|Reviewer(s):||Ekmekçi, F., Özuluğ, M. & Smith, K.|
This species is known from Lake Marmara and lower part of Gediz basin. It is also in the lower Madra river and most likely is more widely distributed between these sites in the rivers of the northern and central Aegean Sea in Anatolia. It has experienced large declines (which are still ongoing) due to massive water pollution in major rivers. It is known from more then five but less then 10 locations (based on pollution as the major threat), and its area of occupancy (AOO), based on the length of inhabited rivers, is estimated to be less than 2,000 km². It is therefore assessed as Vunerable.

|Population:||There are no data available on population trends. It is declining in parts of its range as in Lake Marmara, which is slowly drying out, and in other slowly flowing streams. It is believed to have strongly declined and is now largely extirpated in Gediz river and most likely in Bakir river (not recorded yet) due to massive pollution of these rivers. In the past, it seems to have been able to build up huge populations in the reservoirs in Gediz drainage which might at least partly balance the losses in the natural habitats. The current trend is therefore believed to be decreasing due to the actual losses in the natural habitats.|
|Habitat and Ecology:||Inhabits lakes, reservoirs, standing or slowly flowing canals, and the lower sections of streams and river sections.|
|Major Threat(s):||Water extraction and pollution are the major threats affection this species. Furthermore, reduced rainfall induced by climate change poses an additional threat.|
|Conservation Actions:||None known to be in place for this species.|
