Sažetak
Freshwater ecosystems are exceptionally threatened globally due to increasingly intensive human activities that lead to reduced diversity of freshwater ichthyofauna. This phenomenon has been particularly observed in the Mediterranean region, unique due to the large number of endemic and threatened fish species. The Cetina River is the longest river in Croatia's Adriatic basin. It belongs to the Dinaric karst ecosystem and is a typical karst watercourse. It is characterised by a small number of fish families and a large number of endemic species, and is considered to be one of the most important centres of endemism in this part of the Mediterranean. The Cetina is one of the most exploited rivers in Croatia, with 4 hydroelectric plants that have completely changed the natural appearance of the river and its habitats. In addition to structural changes, the drastic drop in abundance and the extinction of certain endemic species in the Cetina River result from the increasing dominance of introduced species and increasing pollution and water extraction. In order to preserve and protect the ichthyofauna of the Cetina River, management measures are required to improve the water quality and reduce anthropogenic impacts. This work gives an overview of the status of the river's ichthyofauna, with an emphasis on the status of threats and the condition of the population of individual species.
