“…Given the increasing rates of development of urban areas and coastal construction in the Persian Gulf region, anthropogenic activities and climate change will be important threats to the future of biodiversity in marine ecosystems (Griffith, Strutton, & Semmens, ; Henson et al, ; Kamrani et al, ; Segan, Murray, & Watson, ; Sharifinia et al, , ; Sharifinia, Penchah, Mahmoudifard, Gheibi, & Zare, ; Taherizadeh & Sharifinia, ). The impacts of DPs on marine biodiversity include decreases in sensitive species, reductions in plankton abundance, decreases in hard substrate epifauna, and growth rate decreases of seagrasses (Roberts et al, ).…”

Due to extremely high rates of evaporation and low precipitation in the Persian Gulf, discharges from desalination plants (DPs) can lead to ecological stresses by increasing water temperatures, salinities, and heavy metal concentrations, as well as decreasing dissolved oxygen levels. We discuss the potential ecological impacts of DPs on marine organisms and propose mitigating measures to reduce the problems induced by DPs discharges. The daily capacity of DPs in the Persian Gulf exceeds 11 million m3 per day, which is approximately half of global daily freshwater production; multistage flash distillation (MSF) is the dominant desalination process. Results from field and laboratory studies indicate that there are potentially serious and chronic threats to marine communities following exposure to DP discharges, especially within the zoobenthos, echinodermata, seagrasses, and coral reefs. DP discharges can lead to decreases in sensitive species, plankton abundance, hard substrate epifauna, and growth rates of seagrasses. However, the broad applicability of any one of these impacts is currently hard to scale because of the limited number of studies that have been conducted to assess the ecological impacts of DP discharge on Persian Gulf organisms. Even so, available data suggest that appropriately sited, designed, and operated DPs combined with current developments in impingement and entrainment reduction technology can mitigate many of the negative environmental impacts of DPs.

Aquaculture is a crucial industry that can help meet the increasing demand for aquatic protein products and provide employment opportunities in coastal areas and beyond. If incorrectly manage, traditional aquaculture methods can have negative impacts on the environment and natural resources, including water pollution and overuse of wild fish stocks as aquafeed ingredients. Biofloc technology (BFT) may offer a promising solution to some of these challenges by promoting a cleaner and sustainable production system. BFT converts waste into bioflocs, which serve as a natural food source for fish and shrimp within the culture system, reducing the need for external inputs, such as feed and chemicals. Moreover, BFT has the potential to improve yields and economic performance while promoting efficient resource utilization, such as water and energy. Despite its numerous advantages, BFT presents several challenges, such as high energy demand, high initial/running costs, waste (effluent, suspended solids, and sludge) management, opportunistic pathogens (vibrio) spread, and a lack of understanding of operational/aquatic/microbial dynamics. However, with further training, research, and innovation, these challenges can be overcome, and BFT can become a more widely understood and adopted technique, acting as an effective method for sustainable aquaculture. In summary, BFT offers a cleaner production option that promotes circularity practices while enhancing performance and economic benefits. This technique has the potential to address several challenges faced by the aquaculture industry while ensuring its continued growth and protecting the environment. A more broad BFT adoption can contribute to meeting the increasing demand for aquaculture products while reducing the industry’s negative impact on the environment and natural resources. In this context, this review provides an overview of the advantages and challenges of BFT and highlights key technical, biological, and economic aspects to optimize its application, promote further adoption, and overcome the current challenges.

“…The entry of oil-originated pollutants into the estuaries and other habitats, especially in the north western Persian Gulf, in addition to disrupting the life of organisms, have already threatened the health and livelihood of locals who depend on these resources. Responding to the pressing environmental issues in this region, more studies should be formed to develop monitoring frameworks for environmental health in the respective terrestrial and aquatic ecosystems (Shari nia et al, 2015;Lagon., 2007).…”

The Persian Gulf, known for its abundant oil and gas reserves, faces significant contamination from hydrocarbon compounds originating from industrial activities. This study focused on investigating the distribution and source of aliphatic (AHs) and polycyclic aromatic hydrocarbons (PAHs) in the surface sediments of the Northwestern Persian Gulf and the muscle tissues of Jinga Shrimp (Metapenaeus affinis), one of the most commercially exploited aquatic species. The methodology involved sampling Jinga Shrimp in November 2018 from four important fishing areas in Behrgan and Khormousi Estuary: Imam Khomeini Port (S1), Mahshahr Port (S2), Sejafi (S3), and Behrgan Wharf (S4). After determining the sex of the shrimps, male samples were selected for analysis, and a total of 28 samples were collected. Additionally, sediment samples were collected from the same locations. The pollutants in the samples were quantified using laboratory procedures. The results revealed that the average concentration of aliphatic compounds in Jinga Shrimp was 4800.32 (µg g − 1 DW), while sediment samples showed an estimated value of 2496.69 (µg g − 1 DW). By analyzing the hydrocarbon components, the average concentration of EPA Priority List (PAH-16) and measured PAHs (PAH-29) in Jinga Shrimp were in the ranges of 1095.8 to 2698.3 (ng g − 1 DW) and in sediments were 653.6 to 1019.5 (ng g − 1 DW), respectively. The higher concentration of AHs and PAHs in Jinga Shrimp compared to sediments indicated the petrogenic source of these compounds. The predominant PAHs in both shrimp and sediment samples were the compounds with low molecular weight (LMW). Moreover, the aliphatic composition profiles in shrimps were similar to those in sediments, portraying a gradient of even-to-odd carbon dominance. The study found a positive and direct correlation between hydrocarbon concentrations in both shrimp and sediment samples and the corresponding aliphatics, PAH-16, and PAH-29 groups, affirming the potential of the Jinga Shrimp as an indicator of hydrocarbon pollution.
