Heavy metals enter aquatic organisms through direct uptake and contaminated feed, persist via bioaccumulation, and transfer along food chains, posing ecological and human health risks. Metabolically active tissues (liver, kidney, gills, muscle) preferentially accumulate metals, with toxicity influenced by exposure route, dose, and species sensitivity. Field evidence, including studies from Iranian coastal systems, shows that metals such as mercury and nickel may present significant carcinogenic risks even when conventional risk indices are low. Feed safety is therefore a cornerstone of biosecurity and sustainable aquaculture. Industrial aquafeeds serve both as essential nutritional inputs and potential contamination hotspots, as heavy metals may be introduced during raw material sourcing, processing, and handling. Dry aquafeeds are particularly vulnerable due to multi-stage processing, extensive metal–equipment contact, and mechanical and thermal stresses. This study applied a systematic, process-oriented framework to identify heavy metal contamination pathways throughout dry aquafeed production. Scientific literature and regulatory standards were integrated with on-site observations. Production stages were evaluated under Good Manufacturing Practice (GMP) using Hazard Analysis and Critical Control Point (HACCP) principles. Contamination was cumulative, arising from intrinsic raw material properties and secondary processing inputs. Raw material reception—especially mineral premixes, fish oil, rice bran, and process water—was the dominant primary risk source. Mechanical operations were the most critical secondary pathway due to equipment wear. Key CCPs included ingredient acceptance, utility quality, equipment management, and final product verification. Overall, heavy metal contamination is process-driven, supporting preventive HACCP-based control over end-product testing.

دودی کردن یکی از قدیمی ترین فناوری استفاده شده توسط انسان ها برای به تاخیر انداختن فرآیندهای فساد و افزایش مدت زمان نگهداری مواد غذایی می باشد. اما امروزه این فناوری بیشتر برای ایجاد رنگ و طعم/مزه دود با هدف تنوع بخشی به محصولات غذایی استفاده می شود. از بین محصولات غذایی، آبزیان مختلف بویژه ماهیانی مانند قزل آلای رنگین کمان، ماهیان خاویاری و تون ماهیان پتانسیل خوبی جهت تولید محصولات دودی شده دارند. دودی کردن می تواند به روش های مختلفی از قبیل دودی سرد، دودی گرم، دود مایع و یا استفاده ترکیبی این روش ها انجام شود. در مقاله حاضر فرآیند تولید فرآورده های دودی شده آبزیان به روش گرم صنعتی، نحوه نگهداری و نحوه مصرف آنها توضیح داده شده است. همچنین ویژگی های مختلف فرآورده های دودی تولید شده با روش های دودی گرم صنعتی و روش سنتی با یکدیگر مقایسه خواهد شد. تولید فرآورده دودی گرم صنعتی آبزیان به دلیل ایجاد ارزش افزوده بالا و هزینه پایین معرفی به بازار از پتانسیل اقتصادی و اثرگذاری بالایی برخوردار هستند. همچنین فرآیند دودی کردن با تنوعبخشی به سبد محصولات شیلاتی می تواند باعث افزایش مصرف آبزیان در کشور گردد.

Drying is recognized as one of the oldest methods of preserving food against spoilage and has been used since ancient times to extend the shelf life of food products. Today, drying is valued not only for increasing shelf life but also for diversifying seafood products and adding value, thereby improving access to these nutritious foods, even for people living in areas far from the coast.Anchovy (locally known as Moto fish) is one of the most abundant, inexpensive, and nutritionally important fish species in the Persian Gulf, particularly along the coasts of Qeshm Island, with great potential for the production of dried fish products. According to previous studies, anchovy is a rich source of protein, valuable minerals such as calcium, iron, and iodine, and contains moderate amounts of polyunsaturated fatty acids.This article describes the traditional and industrial production of dried anchovy, its storage methods, and its consumption patterns based on scientific literature as well as field observations. Owing to its high nutritional value and the relatively low cost of raw materials and processing, this product has considerable potential to increase seafood consumption in Iran. By choosing industrially produced dried anchovy and observing safety tips in purchasing and consumption, an effective step can be taken toward diversifying the food basket, supplying essential protein and micronutrients, and supporting domestic production.

The Scalloped Spiny Lobster (Panulirus homarus) is a big deal for Iran’s fisheries, especially in the Sea of Oman. Given its high economic value, there’s real potential for aquaculture, but a few tough hurdles stand in the way of commercial success. The lobsters have a long larval phase—six to twelve months, stretching over 11 to 13 stages, which presents significant biological challenges for large-scale hatchery production. Furthermore, existing feed formulas aren’t where they need to be yet, especially in providing enough HUFAs, which are critical for juvenile development, disease resistance, and growth rate optimization. On top of that, wild populations are under a lot of pressure from fishing, creating an urgent necessity for sustainable alternatives to stabilize stock levels.However, Iran’s southern coastline—particularly the Makran extending from Sirik to Gwatar offers highly favorable conditions for lobster farming. This region provides geographic advantages that offset the technical difficulties of production. The sea stays warm (around 26.5°C) and salty (36 to 37.5 ppt), which is just right for these lobsters to grow. The water’s stable, and there’s plenty of coastline where you could build concrete ponds. There are also natural rocky spots where young lobsters like to settle. Combine all that, and this spot looks perfect for developing lobster fattening farms. Research shows that you find the most juveniles in spring and autumn, which lines up well for collecting and raising them to market size in sea cages or coastal ponds.

In shrimp farming, the quality of incoming water plays an important role in maintaining the conditions of the breeding environment, the risks associated with water quality degradation and disease. However, in many farms, water is not adequately prepared and evaluated before entering the breeding ponds. Incoming water management should begin at the water reception stage and continue until its controlled entry into the breeding pond. In this approach, the storage pond, as one of the important components of water management, allows for initial water storage and management. After that, water pretreatment and the use of appropriate preparation methods can help control some of the undesirable substances and factors present in the water. Monitoring the main water quality indicators is also essential to ensure the suitability of the water before transferring it to the breeding pond. Also, simultaneous attention to water conditions and microbial risks allows for better management of factors affecting shrimp health. Accordingly, incoming water quality management in shrimp farming farms should be carried out as a management chain including the storage pond, water pretreatment and water quality monitoring. Implementing this approach can help operators identify potential problems before water enters the breeding pond and provide more suitable conditions for continuing the breeding process.

The rapid expansion of the aquaculture industry and the increasing density of production have exposed this sector to a serious challenge from infectious diseases. Although the widespread use of antibiotics and chemicals has been effective in the short term, it has entailed consequences such as microbial resistance, bioaccumulation, and environmental degradation. In this context, medicinal plants have emerged as a rich source of bioactive compounds with antimicrobial, anti‑inflammatory, and immunomodulatory properties. These plants can be useful as feed supplements for fish to stimulate immune function. Herbal extracts may exert positive effects on animal health through various mechanisms, rather than relying on a single mode of action. It has been shown that the use of medicinal plants as dietary additives enhances immune defence mechanisms. These phytobiological approaches hold promise for environmentally sustainable disease management strategies in aquaculture and support the shift in consumer attitudes towards a demand for safe and sustainable seafood. The benefits offered by herbal therapeutics position them as essential tools for the development of a sustainable and environmentally friendly aquaculture industry.
