Anatolian Rivers

Great Meander River Basin, June 2014

With Turkish ichthyologists, Vasso and I have explored Turkey's Meander Basin (Buyuk Menderes). The team has already sampled over 45 sites on the rivers and 8 sites on the lakes and transitional waters (several site's sampled twice!). This is done in the framework of a project for promoting the Water Framework Directive in their country. Fish will be used to assess the condition of the local water bodies - not an easy task. This will take much science and field ichthyology to perfect. Much also needs to be done to protect the natural fish assemblages and varied aquatic ecosystems of this great valley. The area's waters are threatened since so much must go to agriculture and industry. As is usually the one seems to have any idea of the fishes and other organisms that need these waters. Scientists must not sit back and watch!

Funny pose struck by my friend Kaan Yence, exploring Bafa Lake - one of the basin's most amazing landscapes.
A 'Greek island' on Lake Bafa: Kahve Hisar, its Byzantine Church and huge Pistacia trees full of  nesting egrets.

Atherina caught at Lake Bafa. The lake is polluted and has lost a lot of its fishes. It needs care.

Hiking to the a site for electrofishing near Karpuzlu on a southern tributary of the Cine River.

Tributary of the Cine near Karpuzlu, fascinating landscape near Golcuk village. A porcupine quill (Hystrix indica !!!) was found here.... 
One of may favorite Anatolian fishes Petroleuciscus ninae - could I dare say a common name "Nina's Chub"; this is a young one. The species was described in 2018 by Turan, Kalayci, Kaya, Bektas & Kucuk (Journal of Fish Biology)

Kaan caught these adult Petroleuciscus ninae from the Karpuzlu area. This species survives well in small pond in the drying stream. At the time we caught these, we did not know we were dealing with a new undescribed speceis that is ENDEMIC to the tributaries of the Great Meander (see above).

Vasso with some beautiful Barbus pergamonensis (Bergama Barbrel) in the upper Dandalaz river near Aphrodisias

A really big Luciobarbus kottelati (Kottelat's Barbel) on the upper Ciner river (c. 40 cm).

 Cyprinid Jewels:  Two upper ones are a local Bleak, Alburnus sp., and the lower fish is the local Vimba (V. cf. mirabilis).
Near Kafacakaplancik, the upper Cine river. Deep and full of big fish!

A scarce and poorly-known fish, the un-named Spirlin of the Meander (Alburnoides sp). Upper Cine river.

Stone Loaches (Oxynoemacheilus sp.) are very tolerant of polluted waters - here on the lower Dandalaz near Basaran where nearly all the river-water is taken for agriculture.
An invasive promoted by many dams - the American Sunfish, sometimes called "Japanfish" by the locals.

The Meander meanders no more.  Near Aydin the river is completeley straightened and influenced by severe water abstraction. Despite this state we found 13 fish species here, several alien species.
