Abstract

With its activity the man is changing the ecological conditions of aquatic ecosystems. Channeling, remodeling flows and pollution are the most common patterns of reduced biodiversity. Customization species on changed conditions is a long and sometimes unsuccessful process; so many sensitive species are dying out. In this work I gave a review of the most important anthropogenic influences on the regulation of river flow in karst in the case of the river Cetina, and what are their consequences for the flora and fauna. This grips changes the water temperature, concentration of dissolved oxygen, water flow, habitat and the abundance and species diversity. Ichthyofauna is the best indicator of a negative impact hydromorphological grips. Remodeling of the river Cetina is reduced number of indigenous species and many species are protected under IUCN criteria.
