Abstract
The Department of Veterinary State and Forensic Medicine of the Faculty of Veterinary Medicine, University of Sarajevo, received a request for ichthyofaunal damage assessment in the fishing area of rivers, tributaries and lakes in the municipality of Konjic. The damage was caused by cleaning activities, removal of sediment from the riverbed and damage repair activities on the banks of the upper course of the Neretva River, which was carried out with certain irregularities that are not in accordance with the granted permit. Such irresponsible human activities inevitably have an impact on the living world of the aquatic ecosystem and often cause long-term harmful consequences. Through the presentation of this case, our main goal is to present the different types of harmful consequences resulting from such activities as well as the methodology of their calculation. In addition, the paper also points to violations of certain laws and bylaws governing this segment.
Highlights
Bosnia and Herzegovina (B&H) has significant water resources, which are one of the important factors of general economic development
As a result of the dams built on the Neretva River due to changes in physico-chemical water parameters, the destruction of suitable habitats and preventing fish migration during spawning, certain parts of this river became cyprinid zones and the number of salmonids in the upper course of the Neretva River has decreased to the limits of extinction (Muhamedagić et al, 2008)
This paper aims to present the case of a legally approved procedure of coastal management of the Neretva River, which due to certain irregularities caused various types of damage in this fishing area
Summary
Bosnia and Herzegovina (B&H) has significant water resources, which are one of the important factors of general economic development. The complex of various interventions by which man daily disrupts natural ecological processes and the diversity of ichthyofauna includes the exploitation of forest complexes and the creation of erosive areas, road construction and formation of settlements along rivers and river valleys, wastewater and other facilities built along rivers, unregulated garbage dumps, gravel exploitation, landscaping, removal of stumps, etc. All these activities lead to various forms of physical, chemical and organic water pollution, which adversely affects the living organisms of this ecosystem. Uncontrolled and unplanned introduction of fish species, poaching and inadequate protection of ichthyofauna only complete the spectrum of various negative human effects on this precious natural resource (Muhamedagić et al, 2019)
