Our group of allies is increasing! Artists raise their voices against the total destruction of Balkan rivers – they want to see them protected, not dammed.
The Dalmatian nase is endemic to the Neretva basin in Croatia and Bosnia-Herzegovina. It is primarily found in the mid to lower reaches and delta region of the Neretva River (Croatia) as well as Modro Oko and Desne lakes, Crna Rijeka and Norin rivers, and in Bosnia-Herzegovina the Buna and Krupa rivers and Hutovo Blato wetlands (Glamuzina et al. 2007; Ćaleta et al., 2015). Generally rheophilic but like other karst species, it also resides in sink holes and springs, with relatively cool water (Tutman et al. 2008). Very sensitive to invasive species (Glamuzina et al. 2007), whose presence is often promoted by hydropower development. Listed as endangered in Croatia.
At least two mid- to large-sized (10-50 MW) hydropower facilities in addition to a sea water control dam are planned on the lower Neretva River between Mostar and the sea. These projects could eliminate one of the most important spawning areas of the species in the basin.
- IUCN-Redlist Vulnerable
- EUR-HAB-DIR III
- Bern Convention III
- Hydropower Sensitivity Very High
- Balkan Dam Threat * High
* 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.
