Abstract EN
Diversity, abundance and community structure of fish species in the lower part of the Euphrates River was investigated during May 2016 to April 2017.
Three stations were selected to conduct the work.
Monthly variance of water temperature ranged from 11ºC in January and February to 31ºC in August, turbidity differs from 2.31 in June to 24.10 NTU in November.
The overall values of hydrogen-ion differ from 7.52 in April to 8.27 in November and December.
The overall values of salinity in the work area were 0.91 ‰ in October to 1.52 ‰ in May.
Several fishing methods were used to collect the samples of fishes.
A total of 4380 specimens' of fish were collected included 23 fish species belonging to 23 genera and 11 families, ten of them represented native fish species, eight alien fish species and five marine species.
Oreochroims aureus was the most abundance species formed 34.27 % of the total number then Liza abu (24.66 %) of the total number of species and Carassius gibelo (14.36 %).
Values of three dominate species (D3) was 73.29 %.
The mean values of diversity index (H) in the study area ranged from 1.11 to 1.92, evenness index (J) from 0.53 to 0.90 and richness index (D) from 1.15 to 2.33.
The study showed the dominance of small species of exotic and native fish in the study area and the scarcity of large economic species due to the overfishing.
