 The present study includes the analysis of the morphological change in the Iraqi coastline in Khor Abdullah and the entrance to the Shatt Al-Arab (Al-Ruka Channel), as the northwestern region of the Arabian Gulf is exposed to different erosion and depositions due to the suspended sedimentary load, The comparison between the periods studied showed severe erosion in some coastal areas and depositions in other parts, which led to changes in the shape and extension of the barriers or the sedimentary tongues and made them prominent, especially in the shallow sites (shoals) areas at the entrance to Khor Abdullah and Khor Shaitanah, and those changed parts appear in the maps of the British Admiralty, which draw detailed curves surrounding the varying depths. The extension of the suspended sedimentary load at the head of the Arabian Gulf amounted to 11,014 km2 in the year 2003, which expanded in 2011 to 12,680 km2, by adding suspended sediments of about 1,676 km2 to 6,452,600 tons over 8 years, at a rate of 806.575 tons annually, or 8.5% of the volume of suspended sediments in 1996 due to the decrease of the river flows from the Tigris, Euphrates, and Karun. The line of the lowest tide (zero line) showed a change in the cross-section of the Iraqi waterway lines that it shares with Iran and Kuwait, affecting the location of the approved border line between Iraq and Kuwait, and the largest change was in the width of the entrance to the Shatt Al-Arab (Al-Ruka Channel), and this was influenced by the erosion, sedimentation patterns, and deflection of tidal currents, as well as the temporary effect of port activities in Khor Abdullah. The extension of Abdullah’s Marqat at Ras Al-Bishah reached 15.5 km in 2003, its extension became 17.2 km in 2019 with a varying range of 1.7 km in 16 years, which has increased at lower rates in recent years due to the decrease in the sedimentary load of rivers to legalize water releases. The maximum change in Khor Abdullah in the middle part was 453 meters, which is a contraction in favor of Kuwait at a rate of 453 meters, and in the middle of the Al-Ruka Channel with an average width of 403 meters in favor of Iran, expansion in favor of Iraq was at a rate of 152 and 42 meters at the entrance and middle of Khor Shaitana.","PeriodicalId":491432,"journal":{"name":"Al-maǧallaẗ al-ʻirāqiyyaẗ li-l-istizrāʻ al-māʼhī","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135017913","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}

The current study dealt with knowing the effect of organic pollution on physical and chemical properties in Garmat Ali river, which was represented in two stations, the first station called Al-Mashab, and the second Al-Sindbad. Water and sediment samples were collected monthly during the period from August, 2016 to July, 2017. Numbers of physical and chemical variables were measured during this period (water temperature, light penetration, pH, Salinity, dissolved oxygen, biological demand oxygen, chemical demand oxygen, total nitrogen, total phosphorus and total organic carbon in sediment). The results of the study was showed that water temperature were ranged between 13.2-31.3°C for the first station and 13.4-33.1°C for the second station. The light penetration values were ​​ranged between 20.6-58.5 cm for the first station and 35-65 cm for the second station. The pH values were ​​ranged between 7.5-8.6 for the first station and 7.5-8.5 for the second station. Salinity values were ​​ranged between 1.58-3.16 g/l for the first station and 0.92-2.13 g/l for the second station. Dissolved oxygen values were ​​ranged between 4.66-10.8 mg/l for the first station and 11.85-6.26 mg/l for the second station. The values ​​of BOD5 were ​​ranged between 1.1-4.26 mg/l for the first station and 0.75-4.06 mg/l for the station. The values ​​of the COD were ranged between 8-120 mg/l for the first station and 8-61 mg/l for the second station. Total nitrogen values were ​​ranged between 2.8-29.4 mg/l for the first station and 2.4-33.6 mg/l for the second station. The total phosphorus values were ​​ranged between 1.11-19.6 mg/l for the first station and between 1.24-19.98 mg/l for the second station. Total organic carbon values were ​​ranged between 0.36-2.19% for the first station and 0.32-2.94% for the second station.

Samples were brought from the local markets in Basra governance-southern of Iraq. Results show that the moisture of fish`s muscles was recorded from 69.15 ± 0.91% to 76.83 ± 0.15%, the protein was 16.93 ± 0.15 to 19.56 ± 0.83%, fat content was recorded from 1.64 ± 0.22 to 9.92 ± 0.51%, and ash from 1.81 ± 0.12 to 4.08 ± 0.08%. The statistical analysis shows that there were significant differences (p < 0.05) between the four species in some of the chemical composition ratios above. The nutritional value of energy was recorded from 112.435 to 194.835 Kcal/ 100 g. The findings of this study demonstrate that fish found in Iraqi marine waters serve as a primary source of protein and fat. This information can be useful to consumers, highlighting the nutritional benefits of consuming fish species rich in high-quality food content. Specifically, the Al-Nuweibi Otoliths ruber species should be periodically considered due to its high proportion of animal protein, which can aid in growth and muscle development.","PeriodicalId":491432,"journal":{"name":"Al-maǧallaẗ al-ʻirāqiyyaẗ li-l-istizrāʻ al-māʼhī","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135017916","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}

Review work was done to determine the sizes and densities of the species during the normal conditions in past decades (1975-1995). The results of observations, photography and semi-quantitative sampling which were taken during many visits in the years 2012, 2015, 2016, 2016, 2017, 2018, 2019 and 2020 at Al-Salhia, Abo Al-Kassib, Al-Garmma and Al-Gurnah, were expressed in an ordinal six abundant scales (SACFOR), modified for species sizes and densities. All the species were have superabundance or common scale during the period 1975-1995, whereas at 2018-2020 the abundance of all species except M. affinis, were declined in general, 7 species were absent and 3 more were rare. The amphipods Parhyale basrensis, Platorchestia monodi, the isopod Sphaeroma annandalei and the annelid Namalycastis indica were commonly or frequently found at good state indicating their ability to resist the mesohaline conditions, the euryhaline species M. affinis and B. amphitrite weren’t affected. The study concluded that, in case of long term mesohaline conditions, most of the estuarine macro-invertebrates will be unable to persist and may be shifting to the upper reaches of the River.","PeriodicalId":491432,"journal":{"name":"Al-maǧallaẗ al-ʻirāqiyyaẗ li-l-istizrāʻ al-māʼhī","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134952941","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}
