Sažetak

The Hutovo Blato Nature Park is a small, shallow Mediterranean-type wetland of the River Neretva basin located in the SE of Bosnia and Herzegovina, about 20 km upstream from the Adriatic Sea, near the border with the Republic of Croatia. The River Neretva basin has a special value due to high freshwater fish fauna biodiversity anda high degree of endemism. Because of its natural characteristics, especially its fishes, the wetland area is one of the most important parts of the River Neretva and as such was declared as a Nature Park in 1995 and included in the Ramsar Convention as an internationally important area. The present study analyses the fish fauna of the Hutovo Blato Nature Park which is less known. When drawing up the list of fish species, several data sources were used: our research data from the period 1999-2010, literature data and data on the catch of rare
species collected by the park rangers, professional and sport fishermen, as well as our unpublished data. During our study, 25 fish species were recorded (by including the literature data the number raises to 43), and distributed in 36 genera and 19 families. Native species represent 63%, of which 15 are endemic with a very narrow range of distribution, while 15 species are exotic. Ichthyofauna of the Hutovo Blato wetland is notable for a number of marine species that reside there temporarily. A significant number of species from this list are found in the IUCN Red List of Threatened Species and are mostly endemic. Over the past decades, the tropic status of the wetland has changed as a result of anthropogenic activity, resulting in serious problems. The current status of the Hutovo Blato wetland and fish fauna in the wider area can be described as threatened. Effective habitat protection together with improved water management and measures to prevent the dispersion of exotic species, are particularly important in order to protect high ichthyofaunal diversity of this wetland.
