The species of molluscs were the snails, Lymnaea auricularia, Theodoxus jordani, Physa acuta, Melanopsis nodosa, Melanoides tuberculata while the bivalves were Corbicula fluminea and Corbicula fluminalis. The molluscs were collected from different locations of Shatt Al-Arab river (along the region extended from Abu-Al-Khasib to Garmat-Ali) during 2004 and 2005. Each species consisted of at least 350 adults of uniform size of individuals. The n-alkanes compounds from species of molluscs were extracted and analyzed by high resolution capillary gas chromatography. The total concentrations of n–alkanes in the molluscs varied from 1.50 μg/g dry weight in the T. jordani to 8.78 μg/g dry weight in the C. fluminea during summer and from 2.26 μg/g dry weight to 12.37 μg/g dry weight during autumn. While ranged from 3.15 μg/g dry weight to 12.44 μg/g dry weight and from 1.78 μg/g dry weight to 5.31 μg/g dry weight during winter and spring. The study confirmed lower concentrations of n-alkanes compounds in the molluscs of Shatt Al-Arab river during summer and spring while higher concentrations were recorded during winter and autumn. This is due to several factors which could act to produce such seasonal variations. \u0000 ","PeriodicalId":259361,"journal":{"name":"Mesopotamian Journal of Marine Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130371738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ecological indices increase for the studied key biological groups in 2006 in the three monitored marshes in comparison with that of 2005. Ecological indices of macrophytes and waterfowls assemblages increase steadly from 2005 towards 2007. On the contrary macroinvertebrates and fishes suffer severe decline in 2007 mainly due to reduced water level. Continuous improvement in ecological indices of macrophytes and waterfowls in two of the restored marshes indicated that reduced water level was less harsh to them than to the other two groups. In spite of the slow recovery in ecological indices in the monitored marshes, diversity and richness values fluctuated between poor to moderate status and semi-integrated to disturbed, respectively. Cases of poor status and disturbed were more common and limited good ones were noticed. Most evenness values indicated absence of dominance cases, except two below the acceptable limit (0.5) were scored both were during 2007. What is clear is that the yearly hydrological period plays a major role in manipulating the biodiversity and repercussion ecological indices in the Southern restored marshes. Lower values of ecological indices indicated that the environment of Southern marshes still disturbed and need more time and care to be fully restored. \u0000 \u0000 ","PeriodicalId":259361,"journal":{"name":"Mesopotamian Journal of Marine Sciences","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116452747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A satisfactory site for constructing fishponds is that where the soil is very deep with neutral pH, weather infiltration is very low; mineralization of organic matter takes place rapidly. The present study was carried out to assess different soil parameters in different aged ponds and to find out the relationship between different aged ponds with different bottom soil parameters. Three groups of ponds (1-5 years, 6-10 years and above 10 years) were analyzed. There was no significant change of soil pH among different aged ponds. Significant variations were observed in textural compositions of different aged group pond’s soil. Mean percentages of clay and silt were found to be increasing with the increase of pond’s age. Amount of organic matter and organic carbon also increased sharply with the increasing of pond’s age. No significant variation were found from different aged group ponds for soil pH but the amount of organic matter, organic carbon, silt and clay were significantly increased with the increasing of pond age that may deteriorate the quality of pond’s bottom soil.","PeriodicalId":259361,"journal":{"name":"Mesopotamian Journal of Marine Sciences","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134042496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was established to reduce flood and drain the excess water during the flood seasons, as a canal alternative to Shatt al-Arab during the Iran-Iraq war. It delivers water to the Zubair area and Al Faw town for agricultural purposes. A deterioration of the water quality of the canal was occurred due to many reasons; most importantly was the close of the canal at the junction of Garmat-Ali which is affected by the semidiurnal rhythm of the Arabian Gulf. There is a regulator located at about 22 km from the head of the canal. The main purpose of the canal is to control water drainage during flood and mitigating the effects on both sides land. In this paper the canal was simulated by the existence of controlled barrage on the water way, closed during the flood tide time and opened at the ebb tide. The simulation results after calibration of the mathematical model with field measurements, matched with high accuracy. The tidal effects on the canal can be determined, and the rehabilitation of the canal and water management in the surrounding areas can be preformed.
