Assessment of the physical properties of the seabed and total dissolved solids in the Artificial Reefs site selection (Gulf of Jask, Sea of Oman)

The use of Artificial reefs(A.Rs) are one of the methods used to rehabilitation of fish stocks. This involves studying the grain size composition of bed sediments and  Total Dissolved Solids (TDS), which are crucial components in terms of their location. For this purpose, three stations with three repetitions were selected in the eastern and western of Jask City Bay and the study was conducted in the summer and winter seasons of 2023.In the study of total suspended solids, the minimum value with the mean and standard deviation was 25.9±0.46(mg/lit)at the fourth station in the Eastern basin during winter 2023. The maximum value with the mean and deviation was 36.39±0.62( mg/lit )at the third station in the western basin during summer 2023. The analysis of sediment grain size in the stations revealed that the lowest and highest amounts of sand and silt were found in the western basin at 76.4% (third station, summer 2023) and 88.5% (second station, winter2023) respectively. Firstly, the strength of the substrate (grain size) is the most essential factor in establishing structures, which contributes to ecological and biological success. Considering the optimal range of this component stations, suggested as the suitable areas for installation of A.Rs, one area(Western of  Jask City Bay) and two area(Eastern of  Jask City Bay), respectively.
