“…Formerly, the ranges of salinity in the river were 1.33-2. The degradation of water quality of the southern water led to several cyprinid species disappearance or substantially decreased in abundance, such as Luciobarbus xanthopetrus, Arabibarbus grypus, Luciobarbus kersin, ‫‬Mesopotamichthys sharpeyi and Carasobarbus luteus (Richardson, et al, 2005;Mohamed, et al, 2012Mohamed, et al, , 2013. Hughes and Whittier (2005) mentioned that native species represent the basic building blocks of a fish assemblage, and are a key component of diversity and the exotic species indicate biological pollution and a serious diversion from natural conditions, especially when they constitute a substantial percentage of the assemblage, and including when they are deliberately introduced.…”

“…Many researchers have published their reports on food habits of mullet fish at different water bodies of Iraq; about P. abu [10][11][12][13][14][15][16][17][18][19][20][21] and about Planliza subviridis and P. klunzingeri [14, 22-24, 21, 25], but up until now, the food habit of O. speigleri in the waters of Iraq have not been studied.…”

Food composition and feeding relationships of four mullet species, Planliza abu, P. subviridis, P. klunzingeri and Osteomugil speigleri from the Shatt Al-Arab River, Iraq, were assessed during 2016-2017.Fish were captured by gill nets, cast net and electro-fishing. The index of relative importance (IRI%) of food item was determined by combined the frequency of occurrence and points methods. Monthly variations in feeding activity and intensity of all species were observed. All species were herbivorous and P. abu andÂ P. klunzingeri were considered non-specialized feeders, while P. subviridis and O. speigleri were low specialist feeders. P. abu fed mainly on diatoms (38.6%), high plants (21.7%), algae (15.9%), detritus (15.3%), fish eggs (6.9%) and zooplankton (1.6%).The diet of P. subviridis constituted from diatoms (42.2%), high plants (20.9%), detritus (17.7%), algae (15.9%), zooplankton (2.0%) and fish eggs (1.8%). P. klunzingeri fed mainly on diatoms (35.5%), high plants (29.3%), detritus (16.4%), algae (13.4%), fish eggs (4.1%) and zooplankton (2.4%). O. speigleri were consumed mainly diatoms (52.0%), detritus (17.8%), algae (16.6%), high plants (10.7%), zooplankton (2.5%) and fish eggs (2.4%).Similarity dendrogram among fish species based on their diet showed high significant overlaps among the mullet species. It means that these species might be in direct competition for food in the Shatt Al-Arab River.

“…Fish species identified and counted to calculate their composition in fish community. To each fish species, geographic origin (native or migratory or alien), trophic guilds and environmental degradation tolerance were assigned based on information from literatures (Mohamed et al, 2008(Mohamed et al, , 2012Coad, 2010;Mohamed and Hussain 2012a, b;Hussain, 2014).…”

“…Several studies have been focus on describe water quality and the fish assemblages in the southern marshes since inundation in 2003 (ARID, 2006;Hussain et al, 2009;Mohamed et al, 2008Mohamed et al, , 2012Mohamed et al, , 2014. Some works have been carried out attempting to evaluate water quality change as result of environmental alteration in the marshes by using Water Quality Index, WQI or water characteristics (Al-Saboonchi et al, 2011;Al-Kenzawi et al, 2011) or fish structure changes in the marshes by applying the Index of Biotic Integrity, IBI (Al-Shamary, 2008;Mohamed and Hussain 2012a;Mohamed 2014a, b).…”

The ecological status of the East Hammar marsh was evaluated by using a number of ecological guides: water quality index (WQI), Carlson trophic state index (TSI) and fish integrated biological index (F-IBI) during the period from November 2012 to October 2013. The results revealed that the annual value of WQI varied from 51.1 (marginal) for historical data before desiccation to 67.8 (fair) for data after inundation. The marsh was evaluated to be mesotrophic (TSI= 42.0). IBI scores were calculated from 16 separate assemblage metrics based on the fish species richness, species composition and trophic guilds. The ecological status of the marsh was found to be fair (F-IBI= 47.7) and was slightly better than the status of the marsh after 2-4 years of restoration activities. The rather low improvement in the situation of the marsh indicates that the environment is still fragile and requires the allocation of water share from the Tigris and Euphrates rivers to restore marsh normality.
