River ecosystems of Northern Greece and especially in Central Macedonia lately show a significant environmental degradation mostly due to the excessive exploitation of their natural resources, the pollution they receive and their improper management. Thus, their biological resources are disturbed and exhausted, especially their sensitive fish fauna, with a negative impact in the local socio-economic structure. This paper aims to determine the main environmental problems of the major river ecosystems affecting important risks for the fish fauna and the fish populations in Central Macedonia's region as the rivers Aliakmon, Loudias, Axios, and Strymon. Data about their fish fauna and the ecological status were collected from scientific references, studies, research programs and from the relative 'Fisheries Public Authorities' of each ecosystem. An important number of the species of the fish fauna of these river ecosystems is protected by particular national and international laws and conventions. The findings of the study can support the planning of sustainable and rational environmental friendly management and enhance the relations between biological resources and their habitats. The final results can contribute in the design of a total management plan for the protection of fish fauna in inland waters of Greece.10aALIAKMON RIVER10acentral10aCHEMICAL-PARAMETERS10aenvironmental risks10afish fauna10afishery management10aFRESH-WATER FISHES10aGreece10aMacedonia10anorthern10apesticides10ariver10asustainable development1 aKokkinakis, Antonis, K.  uhttps://icgf.myspecies.info/content/environmental-risks-fish-fauna-main-rivers-central-macedonia-greece
