Four stations positioned along the Mati River (Burrel, Shkopet, Rubik, Milot) are selected in the frame of this study. In this paper, are reported 2896 individuals, from 3 phyla (<em>Arthropoda</em>, <em>Mollusca</em> and Annelida) and 5 classes (<em>Insecta, Malacostraca, Gasteropoda, Bivalvia</em> and <em>Clitellata</em>). The most represented class is Insecta with 30 families. The insect orders with the biggest number of the families are <em>Ephemeroptera, Plecoptera, Trichoptera</em> and <em>Diptera</em>, followed by orders <em>Coleoptera</em> and <em>Odonata</em>. EPT (<em>Ephemeroptera, Plecoptera</em>&nbsp;and <em>Trichoptera</em>) - Biotic Index and Biotic Index parameter (Stroud Water Research Center) are used for water quality bio-classification. Water quality parameters (pH, electrical conductivity, dissolved matter, dissolved oxygen, total suspended solids and nutrients) have been measured in those 4 different stations along the Mati River. The waters quality assessment is based on: NIVA classification (Heinonen et.al., 1997) and the European Community Directive (EEC/EEAC/EC 78/659) on “Quality of fresh waters supporting fish life”. The conclusions from the chemical analyses are in good accordance to those obtained from biological parameters.</p> ER -
