“…diversity, richness and evenness revealed that values were 2.37, 2.95 and 0.88, respectively in Sindbad, and 1.96, 2.94 and 0.72, respectively in Abu Al-Khasib. Present findings are in line with other workers who also observed seasonal changes in the fish diversity indices in this part of Shatt Al-Arab river [47,22,44]. The richness index has a general tendency to show high values during spring months and reached to highest values during May in both sites which could be attributed largely to the penetration of marine migratory species, such as T. ilisha, T. whiteheadi, T. vitriastris P. Subviridis and P. bindus to reproduction or nursery or feeding, or migration route corresponding with increased in salinity.…”

[22] stated that the salinity of Shatt Al-Arab river at Sindbad and Abu Al-Khasib ranged from 1.09 to 2.27‰ and 1.4 to 6.19‰, respectively during 2011-2012. However, the values of 1.6-4.6‰ were recorded at Abu-Khasib site during 2015-2016 [44].…”

“…This serious reduction in freshwater inflows to Shatt Al-Arab river permitted the saltwater to intrude upstream of the river and this has been discussed by several authors [17-19, 3, 20]. Also, several studies have focused on fish assemblage structure in different parts of the Shatt Al-Arab River under these circumstances [21,22,23,24].…”

In 2018, a serious changes in the salinity of the Shatt Al-Arab river, as salinity intrusion progressed further to upper reaches of the river due to sharply decline in river flow. Therefore, the fish assemblage structure in the middle of the river, fromÂ Sindbad and Abu Al-Khasibs was assessed during the period from January to December 2018. Fish were sampled by gill nets, cast net and electro-fishing from both sites. Salinity fluctuated from 2.0â€° (January) in both sites to 16.2 and 25.0% during August in both sites, respectively. 35 and 44 fish species were collected from both sites, respectively, these included 18 marine species in first site and 28 marine species in second site. Poecilia latipinna, Tenualosa ilisha and Oreochromis aureus were the dominant species in first site, whereas O. aureus, Carassius auratus and P. latipinna in second site. The index of species richness, diversity and evenness each showed a consistent seasonal pattern in both sites. The highest value of Bray-Curtis similarity index of fish species between both sites was noted during the period of low salinity. Findings indicate that the salinity values and the percentages of marine and occasional species were considerably higher than that documented in the previous studies on this part of the Â river.Â

PurposeUsing a combination of the geographical information system (GIS) and the Canadian water quality index (WQI), the current study sought to provide a long-term general assessment of the water quality of the Shatt Al-Arab River (SAAR), focusing on its suitability for living organisms. Likewise, SPSS statistics was used to develop a nonlinear WQI regression model for the study area.Design/methodology/approachThe study required four decades of data collection on some environmental characteristics of river water. After that, calculate the WQI and conduct the spatial analysis. Eight variables in total, including water temperature, dissolved oxygen, potential hydrogen ions, electrical conductivity (EC), biological oxygen demand, turbidity, nitrate and phosphate, were chosen to calculate the WQI.FindingsThroughout the study periods, the WQI values varied from 55.2 to 79.83, falling into the categories of four (marginal) and three (fair), with the sixth period (2007–2008) showing the most decline. The present research demonstrated that the high concentration of phosphates, the high EC values, and minor changes in the other environmental factors are the major causes of the decline in water quality. The variations in ecological variables' overlap are a senior contributor to changes in water quality in general. Notably, using GIS in conjunction with the WQI has shown to be very effective in reducing the time and effort spent on investigating water quality while obtaining precise findings and information at the lowest possible expense. Calibration and validation of the developed model showed that this model had a perfect estimate of the WQI value. Due to its flexibility and impartiality, this study recommends using the proposed model to estimate and predict the WQI in the study area.Originality/valueEven though the water quality of the SAAR has been the subject of numerous studies, this is the only long-term investigation that has been done to evaluate and predict its water quality.
