Sažetak
The River Neretva, along with four other locations in the European Mediterranean Basin, has the highest concentration of threatened freshwater fish species (Smith & Darwall, 2006). This is a consequence of water developments in the late 1960’ s when the Neretva River delta was destroyed and more than 5000 hectares of freshwater fish and wildlife habitat lost. At almost same time, six major dams were constructed for hydroelectric production in the upper part of the river. Power and agriculture provide many economic benefits to the region, however, they also changed the impulsive rapid-flowing river ecosystem to a warmer water, slow-flowing series of impoundments. At 18 sampling locations in the Neretva River delta and its tributaries, 38 freshwater fish species, 27 autochthonous and 11 indigenous species, were found. Ten species from the literature have not been confirmed. The determined species belong to 22 families, the most numerous being the cyprinids with 18 species, salmonids with 6 species, gobids and mugilids with 3 species each and lampreys with two species. The remaining families were represented by only one species. The ichthyofauna of the Neretva delta consists of 18 endemic species ; of which 3 are Mediterranean, 13 of the Adriatic watershed, and 2 species Cobitis narentana and Knipowitschia croatica are Croatian endemisms. The species Lethenteron zanandreai, Salmothymus obtusirostris oxyrhynchus, Cobitis narentana, Chondrostoma knerii, Leuciscus svallize, Phoxinellus adspersus, Rutilus basak, Leuciscus microlepis and Knipowitschia croatica have a very small area distribution, existing only in the River Neretva and in certain lakes and watercourses of this area. Three species are critically endangered (8%), 6 species are endangered (16%), 8 species are vulnerable (21%), 2 species are in the category of data deficient (5%), while no threat status has been determined for 19 species (50%). Virtually half the species are in some category of endangerment (45%), and it is important to note that these are mostly endemic species. In the past 15 years, 11 allochthonous species have been found in the Neretva watershed. The majority of alien species were introduced into the mid part of the River Neretva for fish stocking of newly created reservoirs, usually for the purpose of increasing the economic or ecological values of the area. Some may have devastating effects. Our investigations have confirmed the highest fish diversity in the lower part of the river. Half of the Adriatic watershed fish live in the of River Neretva delta. Of the total of 88 species inhabiting the Adriatic watershed of Croatia, about half are found in the River Neretva. Therefore, the Neretva delta represents a very important freshwater fish biodiversity spot.
