The biology of Chondrostoma beysehirense is poorly understood, although it is known to be a detritus feeder. It is also migratory to a small extent, as it feeds and reproduces in different areas of its stream habitat, migrating to springs upstream to spawn (1).
Chondrostoma beysehirense is a member of the order Cypriniformes. In general, cyprinoids are largely freshwater, egg-laying species, all of which lack jaw teeth. The Cypriniformes are composed of five different families, the largest of which is the Cyprinidae, to which Chondrostoma beysehirense belongs. This family consists of more than 2,000 species, including chubs, minnows and carps. As with most cyprinids, it is assumed that Chondrostoma beysehirense does not exhibit sexual dimorphism (5).
