“…In rainbow trout, the hepatic levels of antioxidant enzymes (catalase, glutathione peroxidase and superoxide dismutase) and antioxidant capacity increased in fish diet enriched with 6 and 10 g O. vulgare extract per kg diet compared with control group. However, the addition of O. vulgare extract (14 g kg −1 ) to fish diets significantly decreased the activity of antioxidant enzymes and total antioxidant capacity when compared to control (Rafieepour, Hajirezaee, & Rahimi 2018).…”

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.

“…Previous study showed that the oral administration of rosemary leaf powder (Yousefi et al 2019) and artemisia (Artemisia annua) extract (Sarhadi et al 2020) improved SOD activity in common carp. In addition, Rafieepour et al (2018) showed that different concentrations of oregano extract (Origanum vulgare L.) significantly increased serum SOD activity in rainbow trout. It has been showed that flavonoid and phenolic compounds in herbs and their compounds are responsible for their high antioxidant capacity (Reyes-Cerpa et al 2018).…”

Effects of lavender essential oil nanoemulsion (LEON) on the growth, body composition, haematology and immunity of Oncorhynchus mykiss was investigated. A total of 276 healthy fishes were distributed into 12 cages to four treatments in triplicate. The fishe were fed a diet consisting of 0, 100, 150 and 200 ml/kg of LEON for 60 days. Results showed that WG% and SGR (%/day) significantly were increased at the different levels of LEON (p < .05). The highest of WG (%) and SGR were found in 150 ml/kg of LEON (252.16%) followed by 100 and 200 ml/kg. In contrast, FCR was decreased with increasing of dietary supplemental of LEON. The haematology parameters such as RBC, haemoglobin , haematocrit and MCH were significantly increased in 200 ml/kg of LEON compared to the control. ACH50, SOD, lysozyme activity, IgM and total Ig were significantly higher in 200 ml/kg of LEON treatment compared to the control (p < .05). LEON treatments also had a significant influence on body composition like protein and lipid content. Overall, our results interestingly demonstrated that the effect of supplemental dietary LEON especially at the level of 150 and 200 ml/kg had a positive and significant effect on some growth and immunity of rainbow trout.

“…In the present experiment, decreased MDA levels of fish fed dietary oregano extract can be linked with boosted first-line enzymes of the antioxidative defense (SOD and CAT) involved in the prevention of reactive oxygen species formation (SOD superoxide radical and CAT-H 2 O 2 ). The antioxidant nature of the extract seen as a reduction in MDA levels in the treatment groups compared to the control was also related to an increase in the level of antioxidant enzyme activities [ 16 , 55 ]. Similar results were found in rainbow trout ( Oncorhynchus mykiss ) fed oregano ( O. vulgare ) extract [ 55 ] and zebrafish fed quercetin [ 56 ].…”

“…Several studies have reported dietary plant extracts to be effective on fish immunological responses due to their respective bioactive components [ 18 , 55 , 60 , 61 , 62 ]. Although further research is required to identify mechanisms of actions of exerted growth and immune enhancement effects of oregano extract, authors suggest high levels of polyphenols and flavonoids in O. vulgare extract are possibly responsible for the observed positive effects.…”

This study evaluated the dietary effects of an ultrasound-assisted extract of Origanum vulgare on the growth, antioxidant and immune responses (serum and mucosal) and resistance of zebrafish (Danio rerio) against Aeromonas hydrophila. Four hundred and forty adult zebrafish were distributed into 12 tanks and fed 4 experimental diets including 0% (control), 0.5% (M1), 1% (M2) and 2% (M3) of the extract per kg−1 diet for eight weeks. Fish were then challenged with A. hydrophila and mortality was recorded for 10 days. Results revealed that the extract exerted potent effects on growth parameters of weight gain and specific growth rate. The feed conversion ratio was significantly lower in fish fed extract-incorporated diets. O. vulgare extract improved antioxidant and immune responses, resulting in less sensitivity to oxidative stress and a higher survival rate when challenged with A. hydrophila. Overall, the greatest effects were observed in individuals with 1% dietary inclusion of the extract. These results suggest that the extract from the plant Origanum vulgare possesses a great potential to be used in the aquaculture industry and that zebrafish is an appropriate model for nutrition studies.
