Alburnus volviticus

Yelartza (eng.), Volvi Seelaube (ger.), Yelartza (gr.)

Distribution and Habitat - Greece

Yelartza are reported to reach sizes of just over 200 mm SL (Kokkinakis & Sinis 1995); previously treated as Chalcalburnus chalcoides macedonicus (together with populations from Lake Vistonidis); nomenclature revised by Freyhof & Kottelat (2007). The species currently occurs only in Lake Volvi (Freyhof & Kottelat 2008b). Yelartza are lacustrine but migrate into tributaries to spawn. The major threat to this species is drought or water abstraction from tributaries where the spawning grounds are found.
While irrigation dams block spawning migrations, there are currently no hydropower schemes planned in the drainage.
  • IUCN-Redlist Endangered
  • EUR-HAB-DIR III
  • Bern Convention II
  • Hydropower Sensitivity Very High
  • Balkan Dam Threat * Presently Low

* The assessment of Balkan Dam Threat is based on the loss of habitat that would occur if all or most of the planned hydropower schemes in the distribution range of the species were to be built. For more precise specification see Fish Study, page 8.
