  ABSTRACT: 3 National Museum, Václavské náměstí 68, 115 79 Prague 1, Czech Republic 4 Museo Nacional de Ciencias Naturales, C/ José Gutiérrez Abascal 2, 28006 Madrid, Spain 5 Institute of Fisheries, Zoology and Water Protection, Faculty of Agronomy, University of Mostar, Biskupa Čule 10, 88000 Mostar, Bosnia and Hercegovina 6 Department of Natural Sciences, U.b. Učakar 108, Abstract. The morphometric, meristic and phenotypical characters of the members of the genus Alburnus from the Adriatic Basin were analyzed on specimens from 11 localities, representing eight watersheds. The number of gill rakers, the number of lateral line scales, the number of branched anal fi n rays and the coverage of the ventral keel by scales have the greatest signifi cance in differentiating between species. Signifi cant morphological differences exist between the Alburnus population from Lake Lugano (type locality for Alborella maxima Fatio, 1882) and all the remaining investigated populations. Alburnus from the Neretva River drainage is described as a new species and it is distinguished from other species of the genus Alburnus by the following combination of characters: 13 1 / 2 -15 1 / 2 branched anal fi n rays; 17-26 gill rakers; 40-48 lateral line scales; fi rst anal fi n ray below branched dorsal rays 6-10 or located up to one scale after the last dorsal fi n ray; ventral keel exposed for at least 2 / 3 of a distance between the pelvic fi n base and the anal aperture. The status of the Neretva River basin populations as a separate species was corroborated by genetic analyses, with p-distance between newly described species and A. arborella from the Zrmanja River 1.8-2.2%. by different authors (see Vuković & Ivanović 1971, Dimovski & Grupče 1975, Šorić 1980, Oliva et al. 1988) what made the taxonomy of the bleaks quite complicated and puzzling. Based on the works of Bogutskaya (1997) and Bogutskaya & Naseka (2004), as well as the systematics of Kottelat & Freyhof (2007), genera Alburnus and Chalcalburnus were merged into single genus, Alburnus. Recently, an intensive taxonomic work on the genus Alburnus has lead to a description of several new species from the Black and Aegean Sea Basins, mostly belonging Folia Zool. – 59 (2): 129– 141 (2010) Introduction Although bleaks (genus Alburnus) are widely spread in the waters of the Adriatic watershed, their taxonomy, systematic and actual distribution are still not well understood. Until recently, it was considered that only two widely distributed species inhabit the European waters (Kottelat 1997): Alburnus albidus (Costa, 1838) in the Adriatic Basin and Alburnus alburnus (Linnaeus, 1758) in the other parts of Europe. However, numerous subspecies, morphs and varieties of the later species were recognized

  ABSTRACT: a b s t r a c t . an assessment of DNa integrity in erythrocytes using the alkaline comet assay was carried out to estimate the impacts of water pollution on Balkan loaches (Cobitis elongata Heckel et Kner, 1858) inhabiting the Sava and Kupa rivers, rivers of varying different water quality. The amount of DNa damage in cells was estimated from three different parameters: comet tail length as the extent of genetic material migration, tail intensity (% DNa in comet tail) and tail moment. The results suggest a genotoxicity of the aquatic environment in the Sava river and demonstrated significantly lower levels of DNa damage in fish captured from the Kupa river. This study confirmed that the comet assay, applied to fish erythrocytes, is a useful tool in determining potential genotoxicity of water pollutants. although a good DNa damage pattern for Balkan loach was obtained, due to its global and regional conservation status, only restricted use of a small number of specimens per sampling site could be permitted.

  Article: Conservation status of the genus Cobitis and related genera in Croatia

  ABSTRACT: A b s t r a c t . Nine species of the family Cobitidae live in Croatia. Seven species belong to the genus Cobitis and one each to the genera Sabanejewia and Misgurnus. Species such as the C. jadovaensis Mustafić et Mrakovčić, 2008, C. bilineata Canestrini, 1866, C. dalmatina Karaman, 1928, C. illyrica freyhof et stelbrink, 2007 and C. narentana Karaman, 1928 live in the Adriatic River Basin (the northern Mediterranean), while the C. elongatoides Bacescu et Maier, 1969, C. elongata Heckel et kner, 1858, S. balcanica Karaman, 1922 and M. fossilis Linnaeus, 1758 inhabit watercourses of the Danube River Basin. Although most Adriatic taxa appear to be endemic to this area, some researchers have revealed new phylogenetic relationships, suggesting the possibility of more recent taxa exchange with Danube freshwater fish fauna. All members of these genera inhabit either running and/or standing waters. according to iuCN methodology, S. balcanica, C. elongata and M. fossilis in the Danube watershed and C. dalmatina and C. narentana in the Adriatic watershed have been classified as vulnerable. C. elongatoides is in the lower risk category. the newly determined species C. bilineata, C. illyrica and C. jadovaensis will be in the endangered category. Here we present the majority of a total of 20 areas and water bodies included in the proposal of Natura 2000 and which have been selected for the conservation of the species from the family of the Cobitidae.
