Value of species
It is restricted to the Strymon, Varda and Nestos river basins in northern Greece and Bulgaria. It is also reported to be present in the former Yugoslav Republic of Macedonia (FYROM) but the actual distribution information was not obtained.
A non-commercial species for which there is little population data.
It is a small riverine species that prefers the larger streams and is not found in the smaller creeks. It is absent in channelised habitats and prefers the fast flowing water in mid-stream. It cannot survive where the rivers have been canalised and it is threatened by habitat loss.
The specific name honours the Bulgarian ichthyologist Ivan Buresh, who was able to influence the Bulgarian monarch Boris III to allow Drensky to collect specimens in Bulgaria.
Oxynoemacheilus bureschi is nocturnal and feeds on benthic invertebrates, particularly worms and insect larvae. The breeding season runs from May to July and the spawning takes place among stones, gravels and plants in shallow running water. The fish are sexually mature once they have attained a length of 5 cm.
