“…Fish reared at intensive and semi‐intensive culture systems have been exposed to several physical and chemical stressors such as overfeeding, handling, over‐fertilization, capture, transportation, heat stress and high stocking densities. (Abdel‐Tawwab et al, 2019; Dawood et al, 2020b). The rearing stressors are recognized as oxidative factors associated with overproduction of ROS that causes oxidative stress and deteriorate the general health condition of fish (Dawood et al, 2020c).…”

Aquatic organisms are susceptible throughout their lives to chemical and physical stressors, which negatively affect their health. Various aquatic pollutants derived from industrial effluents, overuse of some agricultural pesticides, herbicides and insecticides may cause devastating toxicological aspects of aquatic organisms and deteriorate their health and growth. They also led to oxidative stress to fish due to the stimulation of the production of reactive oxygen species. Therefore, the need for using natural antioxidants to be used as feed additives is of great importance to counteract the hazardous oxidative stress responses. The use of phytochemicals, which characterized by substantial antioxidative effects, has been raised. Lycopene is the principal carotenoid pigment found in tomatoes and their products, vegetables and red fruits. Numerous studies have recommended the use of lycopene as a powerful antioxidant to attenuate the oxidative stress responses in several fish species exposed to various toxicants or any other stress conditions. Lycopene maintains the health condition of fish by enhancing the immune and antioxidative responses. This review article aimed to elucidate the current information about the potential use of dietary lycopene for several fish species and its capability to attenuate the oxidative stress and haemato‐immunological alterations resulted from aquatic environmental pollutants and other physical stressors. Additionally, the review discusses some aspects regarding the lycopene mode of action to assess the profits that would be of importance in the aquaculture industry.

The motivation behind this article is to give point‐by‐point data about the beneficial applications of oregano feed supplement in fish diets as immunomodulators, antioxidant, antiviral, antifungal and antiparasitic. Use of this plant as feed additive plays an important role in the fish diet when compared to other synthetic feed additives. Oregano is rich in phytochemical compounds including carvacrol and thymol in addition to other phenolic compounds with antioxidant and immune‐enhancing activities. Origanum vulgare extract improved the immunological responses and enhanced non‐specific immunity. Also, non‐specific immunity and the lysosomal activity were significantly increased in rainbow trout fed diet enriched with 3.0 mL essential oil of Origanum onites L kg−1 diet for 60 days. Furthermore, non‐specific immune stimulant, antioxidant and nitric oxide activities were improved due to O. vulgare oil supplementation. In some recent studies, Origanum heracleoticum L essential oil as a growth enhancer increased the antioxidant status. In rainbow trout, the hepatic levels of antioxidant enzymes and the total antioxidant capacity increased by feeding diet enriched with 6 and 10 g kg−1 diet of O. vulgare extract. Therefore, the addition of oregano and/or derivatives as a dietary supplement in fish diet may promote growth and enhance the immunity and health of fish and this will be useful for nutritionists, physiologists and veterinarians.

“…Persian sturgeon ( Acipenser persicus ) originally exist in the southern division of the Caspian Sea and has a high demand due to its pleasant flavours ( Aramli et al, 2015 ). In the modern aquaculture systems, fish suffering from stressful environmental conditions that adversely affect the fish's immune system and increases its susceptibility to infectious agents ( Adel et al, 2020 ; Dawood et al, 2020b ). Fish farmers frequently use a broad range of antibiotics and chemotherapeutics to combat these pathogens; however, it leads to the spread of resistant strains and environmental threats, posing a significant problem in aquaculture ( Dawood, 2020 ; Sutili et al, 2018 ).…”

Algal seaweeds have abundant amounts of active substances and can be used as pharmaceuticals and biomedicals in aquafeeds. In this context, the powder of red macroalgae Gracilaria persica was included in the diets of Persian sturgeon at the rate of 0, 2.5, 5, and 10 g/kg to investigate its role on the growth rate, fillet colouration, haemato-biochemical indices, serum, and skin mucus immunity. The weight gain, SGR, and FCR displayed no significant changes in fish fed varying levels of G. persica ( P > 0.05). The level of total carotenoids was significantly higher in the blood and fillet of fish fed 5 and 10 g G. persica /kg diet ( P < 0.05). Dietary G. persica significantly altered RBCs, WBCs, a nd HCT at 5, and 10 g/kg, whereas the Hb was increased in fish fed 5 g/kg ( P < 0.05). The blood total protein and albumin were significantly increased in fish fed 5 and 10 g/kg ( P < 0.05). No significant alterations were observed on ALT, AST, ALP, and glucose levels of fish fed varying levels of G. persica ( P > 0.05). Serum Ig, lysozyme, superoxide dismutase, catalase, and respiratory burst activities were increased in fish fed 5, and 10 g/kg than fish fed 0 and 2.5 g/kg diet ( P < 0.05). The level of total protein and lysozyme activity in the skin mucus were significantly higher in the blood and fillet of fish fed 5, and 10 g G. persica /kg diet than fish fed 0 and 2.5 g/kg ( P < 0.05). Based on the obtained results, G. persica can be used as a feasible feed additive in the diets of Persian sturgeon at 5–10 g/kg diet.
