Antioxidants effects and resistance against pathogens of Colossoma macropomum (Serassalmidae) fed Mentha piperita essential oil

Abstract

Immunostimulants in farmed fish diets has been considered an effective approach to health management. This study aimed to assess antioxidant effects and resistance against pathogens of Colossoma macropomum (tambaqui) fed essential oil (EO) of M. piperita at 0%, 0.5%, 1.0% and 1.5% kg −1 commercial feed during 30 days. Tambaqui were challenged with Aeromonas hydrophila and did not present clinical signs of alterations. Higher hepatic catalase activity was observed in fish fed 1.0% of M. piperita EO, compared with 1.5%. Renal superoxide dismutase and glutathione peroxidase decreased in the fish fed M. piperita EO. Hepatic and renal lipid hydroperoxide increased among fish fed diets with 1.0 and 1.5% of EO. Tambaqui fed 1.0% of M. piperita EO showed respiratory activity increase, compared with 0.5%. Monocytes and PAS-GL were abundant in fish fed higher EO concentrations. Reduction in monogenoideans abundance was observed in fish fed 0.5 and 1.0% of EO. Although anti-helminth effects were observed, M. piperita EO in tambaqui diet did not promote leukocytes and lysozyme activity increases at the concentrations assessed. It can be suggested that other concentrations should be tested in future studies, as the combined use with other products, such as immunostimulants and probiotics.

Tarragon (Artemisia dracunculus) Essential Oil at Optimized Dietary Levels Prompted Growth, Immunity, and Resistance to Enteric Red-Mouth Disease in the Rainbow Trout (Oncorhynchus mykiss)

“…TGO enhanced antioxidant capacity, as stimulated the antioxidant enzymes, SOD, CAT, and GPx. Similarly, the stimulating action of PEO on antioxidant enzymes is also reported in fish [94][95][96].…”

“…Also, Moringa oleifera supplementation has a positive effect on fish growth and natural anti-stress phytotherapy due to its phenolic and flavonoid compounds (Elabd et al, 2019). Besides, the use of Mentha piperata in fish diets has promoted growth performance and immunity (Ribeiro et al, 2018).…”

Effects of Dietary Peppermint (Mentha piperita) Essential Oil on Growth Performance, Plasma Biochemistry, Digestive Enzyme Activity, and Oxidative Stress Responses in Juvenile Nile Tilapia (Oreochromis niloticus)

“…Peppermint plant extracts can be found in various forms, such as powder, aqueous extracts, or essential oil. However, peppermint essential oil (PEO) is a more concentrated extract, consisting of high proportions of menthol (33-54%), menthone (7-18%), and menthol acetate (4-13%) [16][17][18][19]. Therefore, in addition to improving digestion, peppermint exhibits potent antioxidant [16,17], antifungal [7,18,19], and antibacterial [7,[19][20][21] properties, which may contribute to enhancing intestinal health through modulation of microbial activity and reduction in inflammatory processes [22], thus alleviating stress.…”
