Abstract

The study was carried out during 2003-2004 as monthly. It is studied on effects of SAND AND GRAVEL EXPLOITATION on FISH abundance and species number of TAJAN RIVER. 3 stations were selected for sampling in this study. FISH community of TAJAN RIVER comprised 3 families Gobiidae, Cobitidae and Cyprinidae, among which the highest species number was observed in Cyprinidae (7 species). The highest and least abundance of FISH were observed in station 3 (47%) and station 2 (11%), respectively. The dominant species of this river was Capoeta capoeta, which its abundance was 52.3%. The least and highest species number belonged to station 2 (3 species) and station 3 (9 species), respectively. Also, statistical analysis showed that the abundance difference between these 3 stations was significant and abundance and species number of FISH were found in negative correlation with TSS, TDS and EC. Exploitation of sand and gravel had unfavorable influences on destabilisation of river substrate and FISH habitats.
