The levels of trace metals Co, Cu, Ni and Zn in both dissolved and particulate phases of water from six branches of Shatt Al-Arab River have been investigated during two seasons, spring and summer 2006 by means of Atomic Absorption Spectrophotometry. Levels recorded in μg/ml were: Co (0.019-0.078), Cu(0.163 - 0.240), Ni(0.035 – 0.094) and Zn (0.130–0.215) in dissolved phase during both seasons compared to particulate phase in which levels recorded in μg/g were Co (11.10 – 26.468), Cu(76.340- 376.543), Ni (7.778 – 150.676) and Zn (222.546 – 654.128). These levels were higher than most previous studies at the same sites. It is appeared that all studied branches are highly polluted and water appears highly turbid, viscose and greenish in color due to the expected abundance of phytoplanktons.

Laboratory experiment was conducted to evaluate the short term toxicity of gas oil in the survival rate of aquatic crab Sesarma boulengeri residing the intertidal zones in the banks of Shatt Al-Arab River. Crabs were collected by hand and put in a tank of 20 l capacity contains filtered water from Shatt Al-Arab River close to collection site. In the lab crabs were classified into 1) Juvenile male, 2) Mature males, 3) Juvenile females and 4) mature female. In separate containers, 10 of crabs of each class in triplicate were put in each container and exposed during summer season to different concentrations of gas oil, 0.5, 2.5, 5, 7.5 and 10 ml/l in addition to control sample. The crabs were monitored every 24 hours and the mortalities were recorded numerically. The Juvenile male showed the highest resistance to gas oil followed by Juvenile female, then the mature males and finally mature females showed the lowest resistance to gas oil. Moreover, the toxicity of gas oil increased with exposure time.

Mesopotamian Journal of Marine Science, Volume 23, Issue 1, Pages 49-61

Environmental radioactivity is measurable in the water and sediments of selected areas of the southern Iraq marshes and Main Drain River. Chemilum in essences technique is used for the calculation radiation dose for the selected samples of the study. Its value was (4.13 μ rad /h). Solid state track detectors method is used, the detector (CR- 39) after putting this detector in the waters of the selected stations. After making the track, it is compared to control samples. Then, radiation dose is calculated which is (4.13 μ rad / h). It is found that the results of both methods are too close to one another through the limited of the calculation wrongs. To measure the radioactivity of the sediments gamma spectroscopy system with sensitivity level (0.5 Bq/kg) is used. The results showed that no radiation pollution is there in the samples selected, although the area contains some war machines that are destroyed with depleted uranium in the second gulf war. This goes in line with other studies, showing in dissolution water of depleted uranium as for the radioactivity in sediment samples, it sensed 137Cs with level (26.35 Bq /kg.) and results of uranium 238 U. With depleted uranium in the second gulf war. These accords with the local and international studies concerning the dissolution of depleted uranium in water. for knowing the type of isotopes in the water of the natural marshes gamma spectroscopy is used, using sodium conter. it is found that the most important isotope Cs-137, which is one of the radioactive isotopes resulted from the nuclear weapone experiments on the surface of the earth and result of uranium U- 238.

Impacts of salinity and food on survival of larvae of shrimps (Macrobrachium nipponense), were studied. Larvae were cultured under laboratory conditions since their release from their adults that were brought from the Shatt Al-Arab River at Garmat Ali region. Larvae at early development stages were subjected to ascending concentration of salinity (5, 10, 15, 20, and 25 %) to determine the differences in survival ratio. High survival rates were found in 5, 10, 15 %. No salinity influence occurred on development and feeding concentration higher than 15 %. The result showed that tolerance of larvae of species was greater in earlier stages. It was found that larvae preferred food on newly hatched Artemia, as a result of highest survival rates obtained at 15 %.

Feeding and feeding habits of larvae (Barbus sharpeyi) studied after 7 days of hatching .in order to investigate the natural food and feeding habits of larvae from this stage until fingerling. The study started during March to the end of October 2006. Fullness index and food item percentage were determined for each larvae using point and Numerical methods. The environmental parameter for the ponds shows that all of the parameters were suitable for the culture of Bunnei. The result showed that a significant shift in food habits was occurred according to age. In the first weeks only plants remain and green algae (Oscillatoria sp., Cladophora sp., Spirogyra sp.) occurred with a percent of 23%, protozoa (Euglena sp.-Volvox sp.) 49.3% with some artificial food 9.9% and unidentified materials 9.4%. During the fifth week the food items showed increase in the percent of phytoplankton (Nitzschia sp., Gymnodinium sp., Navicula sp., Fragilaria sp., Diatoma sp., ladophora sp., Cyclotella sp. and Keratella sp.), and zooplankton (Rotifera-Copepoda) both with 12.7%, crustacean (Trichotria sp., Brachionus sp., Moina sp., cartia sp.) and shrimp larvae (Metapenaus sp.) 13.4%. All these items were appeared during the last months, and increased during the last fifth rearing month (May) to reach 35%. During the last months of the study there was increase in the occurrences of aquatic remains, filamentous algae and Alpha alpha remains, which was used by the farmer as daily supplementary food in the last months of the study. All food and feeding habits were exhibits fluctuations with age, length and environmental conditions.

Indoor rearing of newly hatched Bunni larvae Barbus sharpeyi was carried out at the Marine Science Center in April 2005. Larvae were reared under controlled condition. These larvae fed on three food types, live food: the Rotifer Brachionus calyciflorus, the brine shrimp Artemia franciscana, the Cladocera Moina affinis, and artificial food NRD. The results showed that rearing of larvae during 28 days gave high growth rate and survival rate of fish larvae fed on live food compared with those fed on artificial feed. The average of length and weight of fish larvae fed on B. calyciflorus were 41.9 mm /larvae and 113.5 mg /larvae, respectively, whereas the average of lengths and weights of larvae fed on A. franciscana were 37.7mm / larvae and 110.2 mg / larvae, respectively, and those fed on M. affinis were 33.5 mm / larvae and 94.6 mg / larvae in terms of length and weight, respectively. The average length and weight result from artificial food NRD, were 28.4 mm / larvae and 83.6 mg / larvae, respectively. The survival rate was higher on rotifer treatment (82.5 %), whereas lower values were recorded (75.9, 74.6 and 62.4 %) for A. franciscana, M. affinis and NRD, respectively.

In this study, the metallic element Nickel has been determined in water samples from selected stations along the southern part of Shatt Al-Arab river which extended from: 1) Garmat Ali, 2) Mhelah in Abu Al-Khaseeb, 3) the discharging point of Karon river in Shatt Al-Arab River, 4) Al-Seebah in front of Abadan refinery and 5) Al-Fao, the point between Al-Nagha'ah and the Costumer Station. A spectroscopic method was adopted for determination of nickel after the formation of complex between nickel ion and porpharine compound which already prepared from the reaction between pyrrole and benzaldehyde (0.8 moles each) by soxhlet in prop ionic acid for 30 minutes. Measurements were performed at wave length 515 nm. For comparison and accuracy detection of this method another measurements were done by Atomic Absorption Technique. Values recorded spectrophotometerically for nickel were: 0.0860, 0.064, 0.063, 0.107 and 0.0865 mg/l for the stations 1-5 respectively compared with values 0.0865, 0.065, 0.065, 0.1085 and 0.0868 mg/l for the same stations respectively. As it is expected, the highest level of nickel was recorded in station 4 which is affected by discharging effluent from Abadan refinery. The study revealed that this complex is suitable for the determination of Nickel in water samples.

Ten marine fish species were collected from Eastern Al-Hammar marshes during the period, from November 2004 to October 2005 (location the between Al-Mashab and Al-Naggara). The lowest number (one species) was collected in January and the highest (eight species) in April and June. The more dominant species was Tenualosa ilisha, which comprised the vast number of the marine individuals. Most of the fishes sampled were juveniles, especially the individuals of T. ilisha, Thryssa mystax and Liza carinata. Food analysis showed that more the percentages of stomachs food-containing were more than 96%. Stomachs of T. ilisha, L. carinata and L. subviridis were diatoms, algae and zooplankton as well as organic and inorganic materials while stomachs of T. mystax and Bathygobius fuscus contained zooplankton, insects, small fishes and shrimps. The East Al-Hammar marshes were considered as nursery (protection and feeding) for several marine juveniles species.
