| Abstract | ||||
| Forty-eight species of the Osteichthyes fish were obtained in two selected stations in the Shatt al-Arab River (Sindbad and Abu -Al-Khaseeb) after the decline of salt incursionduring the study period extending from January 2019 to December 2019, with all species present in the first station and 34 species at the second station. The number of native species in the first station was 11 species, and 8 species in the second, as well as, the number of alien species reached eight species in each station, while the number of marine species reached 29 and 18 species for the first and second stations, respectively. 4189 fish were caught from the study area, including 2879 in the first station and 1310 fish in the second station. The results of the numerical abundance showed that two species constituted 61.65% of the number of individuals of the species caught from the first station; these are P. abu (1090) fish, equivalent to 37.86% and C. auratus (685) fish, with a percentage of 23.79%. Additionally, four species comprised 56.3% of the total number of fish caught at the second station: C. auratus (240 fish, 18.3%), P. latipinna (193 fish, 14.7%), P. abu (167 fish, 12.7%), and O. aureus (139 fish, 10.6%). The overall diversity, richness, and evenness index value of the first station were 2.1 (0.88- 2.13), 5.9 (1.47- 3.65), and 0.54 (0.33- 0.79) and for the second station were 2.6 (1.81- 2.48), 4.6 (1.33- 3.53) and 0.72 (0.77- 0.93), respectively. | ||||
