Chondrostoma kinzelbachi, the Orontes nase or Levantine nase, is a species of nase, a genus of fish belonging to the family Leuciscidae.[1] It is endemic to the Orontes River basin, historically occurring in Turkey and Syria. It is a fairly small freshwater fish, ranging from Script error: No such module "convert". to Script error: No such module "convert". SL.[2][3]

The Orontes nase is distinguished from congeners by its usual pharyngeal tooth formula of 7-7, as well as by other subtle morphological traits, such as gill raker count and scale structure.[2][4] It is particularly closely related to C. ceyhanensis and C. toros, with these three species forming an "eastern Mediterranean" clade; the Mesopotamian nase (C. regium) falls outside this clade, but is also a very close relative. These four species split from their closest relatives in the Balkans ~4.8 million years ago, and diversified further 2.5–3.0 Mya, coinciding with uplifting of the Anatolian Plateau.[1][4]

As of 2013, the Orontes nase was assessed as endangered by the IUCN.[5] Its range has been drastically reduced over the years, and it is probably now extirpated in Syria. Its decline is attributable to exploitation and pollution of local waterways; the two waterways it is still known to inhabit are also threatened by these factors, as well as reduced rainfall, worsened by climate change.
