Softmouth trout

Softmouth trout are the most intriguing member of the genus Salmo; previously known as Salmothymus (Stearly & Smith 1993). Five distinct populations exist; in the Jadro (Sušnik et al. 2007), Vrljika (Snoj et al. 2008) and Krka rivers of Croatia, the Neretva Basin in Bosnia-Herzegovina (Snoj et al. 2002), and the Zeta and Morača rivers) in Montenegro (Mrdak et al. 2012, Mrdak, pers. Comm). The taxonomic status of these populations remains controversial, so each deserves protection. The population in the Krka River is on the brink of extinction. Several small fragmented sub-populations have been recently found in the Trebižat and Bregava systems of the lower Neretva basin (Glamuzina pers. comm.). Jadro River softmouth have also been transplanted into the Žrnovnica River (not shown).

Planned dams on the upper Neretva River between Konjic and Glavatičevo threatened to exterminate 50% or more of Neretva River populations. Planned dams on the Morača River would most likely eliminate the species in that system.

  • IUCN-Redlist Endangered
  • EUR-HAB-DIR ---
  • Bern Convention ---
  • Hydropower Sensitivity High
  • Balkan Dam Threat * Very 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.
