Shrimp fishing along the Makran coasts is one of the most important seasonal economic activities in the Pazm and Konarak areas, carried out by a large number of traditional fishing boats. During the authorized fishing season (from September to December), each boat catches approximately 150–160 kg of shrimp per day. In addition to this target catch, a considerable amount of bycatch, including tongue sole, flounder, lizardfish, mullet, and other aquatic species, is also captured in the nets. Field observations in Pazm and Konarak showed that for every 150 kg of shrimp caught, about 50 kg of bycatch is generated, accounting for approximately 25% of the total catch. The largest proportion of bycatch consists of tongue sole (about 40–45%), followed by lizardfish (25–30%), mullet (15–20%), and other species (10%). In this study, several simple and low-cost measures—such as modifying mesh size, using bycatch reduction devices (BRDs), and adjusting fishing time—are proposed to reduce bycatch. The implementation of these methods can significantly decrease the capture of non-target species and improve the sustainability of shrimp fisheries.

AbstractOil pollution is one of the most significant threats to marine ecosystems. Its destructive impact on aquatic organisms, food chains, and the quality of coastal environments makes it essential to develop sustainable and cost‑effective solutions. Oil‑degrading bacteria are a group of microorganisms capable of breaking down petroleum hydrocarbons. These bacteria, naturally present in the environment or applied through biotechnological approaches, play a vital role in cleaning up contaminated areas. This article discusses the processes of identifying and isolating effective bacterial strains, laboratory techniques for their cultivation and enhancement, and field application strategies including biostimulation (promoting the growth of native bacteria) and bioaugmentation (introducing selected strains). It also presents examples of successful projects worldwide from the coasts of Alaska and the Mediterranean to the Persian Gulf, to compare efficacy and environmental adaptability. Findings indicate that the targeted use of native bacterial strains with high tolerance to salinity and temperature can significantly accelerate and improve the efficiency of marine bioremediation, thereby helping reduce environmental damage caused by oil spills.

The Iran–Reshadat shipwreck, formerly known as Bergen Maru, located in northern Bushehr Province of Iran, southeast of Bahregan Bay in the northwestern Persian Gulf, represents a rare convergence of historical and environmental values. Originally a wartime vessel and a remnant of the Iran–Iraq conflict, the structure has, over recent decades, evolved into an active artificial reef supporting diverse marine organisms and seabirds. In this study, field observations were integrated with data from scientific literature and documented reports to assess the ecological, cultural, and tourism-related capacities of the vessel. The results indicate that, with an approximate length of 166 m and a beam of 23 m, Iran–Reshadat is the largest shipwreck converted into an artificial habitat with an exposed superstructure in the Persian Gulf. The vessel provides an appropriate physical framework for seabird nesting and breeding, including confirmed breeding of the Bridled Tern (Onychoprion anaethetus) within the chambers of all three superstructure towers and a documented case of Lesser Crested Tern (Thalasseus bengalensis) breeding on one of the towers. In addition, the structure has enhanced local marine biodiversity and food-web complexity, thereby generating considerable habitat value. Beyond its ecological role, the vessel’s historical and cultural significance, together with distinctive surrounding attractions, confers substantial potential for development as a conservation-oriented marine ecotourism destination. Finally, this study proposes recommendations for sustainable management, responsible tourism development, habitat conservation, and the potential transformation of the site into the first underwater museum of the Sacred Defense.

Spirulina contain numerous nutritious and bioactive compounds and, due to these compounds, has a high potential for fortification of food products and producing functional foods. The conclusion of the studies showed that the main part of the chemical composition of Spirulina consist of protein (55-70%), however carbohydrates, dietary fibers, fats containing omega-3 fatty acids, minerals and pigments, especially phycocyanin, are also present in the structure of this microalga. Among food products, bakery products, dairy products and cereal-based products have a high potential for fortification with Spirulina. In addition, energy snacks, beverages, baby food, desserts and food seasonings also have this potential. Fortification of food products with Spirulina will increase their nutritional value and also add bioactive compounds to the formulation of basic products. Paying attention to sensory characteristics of fortified food products has particular importance, so that, in addition to achieving the aforementioned benefits, they are also accepted by consumers.

This project was carried out from June to September 2023 in three farms from Line 2 of the Gomishan shrimp site, Golestan Province. One of the problems of aquaculture farms is the lack of accurate information on the quantitative and qualitative conditions of the ponds. In this regard, with having this data, managing the conditions and biotic and abiotic factors of the farms can be the solution to issues and problems of shrimp farms, including improving water quality, improving shrimp growth and health, and ultimately maximizing production fluctuations. In present article, the shrimp farms of the Gomishan shrimp site were chosen as a model and its biotic and abiotic factors of the farms were introduced. Then, the role and importance of each of these factors in the management of shrimp farms were discussed. Finally, relevant promotional recommendations were presented in order to manage the biotic and abiotic factors in the Gomishan shrimp site.

The whiteleg shrimp (Penaeus vannamei) is one of the most important aquaculture species in the world, and improving its growth and strengthening its immune system plays a key role in increasing productivity and reducing losses. The expansion of intensive shrimp farming is accompanied by challenges such as reduced growth, weakened immune system, and increased susceptibility to diseases, which has raised the widespread use of antibiotics as an undesirable solution. Therefore, finding safe, efficient, and environmentally friendly feed additives has been proposed to improve growth performance and strengthen the immune system of shrimp. In recent years, the use of mineral nano-supplements, especially zinc oxide nanoparticles, has been considered as novel food additives in aquaculture. These nano-supplements are able to increase nutrient absorption, enhance immune responses, reduce oxidative stress, and improve resistance against pathogens. According to the results obtained in previous studies, mineral nano-supplements, including chitosan-coated zinc oxide nano-supplements in the diet of western white shrimp, promote growth indices and immune response of shrimp and have a positive effect on shrimp growth and nutrition by improving the activity of digestive enzymes. Therefore, the use of nano-carriers to deliver food safety stimulants in shrimp nutrition seems promising.
