“…Maintaining a healthy intestine supports the continuity of its vital role in digestion and absorption, which significantly affects growth [ 106 ]. The improvement indicator of intestine health is an increase in the absorption area due to an increase in the intestinal secretion sources (submucosal tissues, goblet cells and crypt, and tunica muscularis), free of inflammatory and/or degenerative alterations, as well as the villus number, height, and width [ 107 , 108 ]. In this regard, dietary oregano EOs positively impact the intestine histomorphometry of the common carp fingerlings, including an improvement in the morphological structure of the intestinal villus [ 108 ].…”

The aquaculture sector is one of the main activities contributing to food security for humanity around the globe. However, aquatic animals are susceptible to several farming stressors involved in deteriorated growth performance, reduced productivity, and eventually high mortality rates. In some countries still, antibiotics and chemotherapies are comprehensively applied to control biotic stressors. Aside from the apparent benefits, the continuous usage of antibiotics develops bacterial resistance, deteriorates bacterial populations, and accumulates these compounds in the aquatic environment. Alternatively, environmentally friendly additives were used to avoid the direct and indirect impacts on the aquatic ecosystem and human health. In aquaculture, medicinal herbs and extracts are extensively used and approved for their growth-promoting, anti-inflammatory, and antioxidative properties. Herbal essential oils contain many bioactive components with powerful antibacterial, antioxidative, and immunostimulant potentials, suggesting their application for aquatic animals. Essential oils can be provided via diet and can benefit aquatic animals by improving their well-being and health status. The use of essential oils in aquafeed has been studied in a variety of aquatic animals to determine their beneficial roles and optimum doses. The outputs illustrated that herbal essential oils are exciting alternatives to antibiotics with prominent growth promotion, antioxidative, and immunostimulant roles. Herein, we reviewed the beneficial roles of essential oils in aquaculture. This review also aims to describe trends in herbal essential oils use, mainly in commercial fish species, and to analyze different factors that affect essential oils’ efficacy on the growth performance, antioxidative, and immune responses of finfish species.

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.

“…Fish digestion and absorption depend heavily on the intestines [52]. Several morphological characteristics of the gut (villi height, muscular) and digestive enzymes (protease, amylase, and lipase) indicate the presence of a healthy gut within fish [53]. It is also believed that the higher or wider the microvilli of the intestinal epithelial cells, the broader the surface area for absorbing nutrients [54,55].…”

This study is aimed at exploring the effects of Bacillus coagulans NRS 609 on the growth performance, intestinal health, antioxidant activity, and immune response in common carp (Cyprinus carpio L.) by colonizing the intestinal tract with the beneficial strain. Gavage B. coagulans with GFP-tag at 109 CFU/mL into common carp for 7 days. Results indicated that B. coagulans were maintained in the intestine for at least 14 days. Four groups fed B. coagulans at different levels of inclusion, including 0 (CK), 1 × 10 7 (A), 1 × 10 8 (B), and 1 × 10 9 (C) CFU/g of feed for 8 weeks. Experimental groups showed significantly better growth performance than the control ( P < 0.05 ). The treatment groups had higher digestive enzyme activity, villus height, and muscle thickness than the control ( P < 0.05 ). Supplementation with B. coagulans also altered the composition of the intestinal flora. In addition, an enhancement of the antioxidant enzyme and a reduction of malondialdehyde in the liver were observed with the addition of B. coagulans ( P < 0.05 ). Moreover, the cytokines of IL-1β and IL-12, IL-10, and TGF-β, significant upregulation in experimental groups ( P < 0.05 ). Based on the results, the optimal level of B. coagulans was 107 CFU/g in diets for common carp.
