Life history traits of the Neretva roach, Rutilus basak Heckel, 1843 (Pisces, Cyprinidae): biological – ecological contribution for the conservation of freshwater fish biodiversity

The present status, distribution, habitat, population structure, threats and conservation needs of the freshwater Neretva roach, Rutilus basak Heckel, 1843 are presented. Although inhabiting a restricted area which includes the Adriatic Sea watershed in Croatia and Bosnia and Herzegovina, only some biological and ecological population parameters are available. Lately, this species also faced with significant changes of taxonomy status raising the question of whether name changes have an impact on conservation status. Therefore more information about its biology is essential to develop appropriate conservation status and strategies. In this paper, we address these cases with a review of the relevant scientific literature. Our review speculates about possible outcomes of taxonomic change, primarily an impact on conservation efforts or affecting on reducing protection. Our study revealed that taxonomic change may have no predictable effects on conservation, while better understanding of biological-ecological status is always an important addition to our knowledge about the organisms that we want to protect. The combination of biological-ecological information and taxonomic status can be a useful tool for indicating failures in conservation management, but also for suggesting more effective actions. Finally, this study shows how this species can be good indicators for monitoring the success of biodiversity management in distributional areas.
