“…A number of studies reported the usefulness of EOs from different plants in aquaculture diets. These studies have suggested that EOs could improve not only the growth performance but also the health status indicated by blood parameters (Ngugi et al, ; de Souza et al, ). Similar results were observed in the current study in terms of fish growth, feed utilization and blood parameters.…”

“…The use of plant-based feed additives received increasing attention due to their market availability at low-cost and less environmental impact (Cuesta, Rodríguez, Esteban, & Meseguer, 2005;Fazio, Cerezuela, Panuccio, Cuesta, & Esteban, 2017). Especially, essential oils (EOs) extracted from plants among phytoadditives have a remarkable potential for using in fish diet (Ngugi, Oyoo-Okoth, & Muchiri, 2017;de Souza et al, 2019;Toni et al, 2015). Essential oils contain functional molecules with wide spectrum of biological activity (da Cunha, Heinzmann, & Baldisserotto, 2018).…”

The aim of the present study was to evaluate the effects of essential oil extracted from bergamot (Citrus bergamia) peel on growth performance and health status of European sea bass juveniles (5.10 + 0.05 g). Test diets supplemented with 0.0%, 0.5%, 1.0% and 2.0% bergamot peel oil (BPO0, BPO0.5, BPO1 and BPO2) were fed to experimental fish for 60 days. At the end of the experiment, the best growth performance was obtained in the BPO0.5 and BPO1 groups (p < .05). No significances were found for haematological parameters including red blood cell count, haematocrit and haemoglobin concentration at the end of the feeding experiment. There were significant differences between the total protein, cholesterol, alkaline phosphatase and glutamic oxaloacetic transaminase (p < .05) between the BPO0.5 and BPO1 supplemented groups and the control group with no BPO addition. The addition of BPO showed significant differences in immune parameters such as lysozyme activity, total myeloperoxidase content, superoxide dismutase and glutathione peroxidase activity between BPO0 and BPO supplemented groups (p < .05). It might be concluded that dietary addition of 0.5%‐1% BPO could increase the growth performance and feed utilization with improved health status in sea bass juveniles.

“…With 5% O. basilicum in the diet of Oreochromis mossambicus, the length of the fish increased (Karpagam and Krishnaveni, 2014). Also, 2ml/kg of basil essential oil improved the growth of Nile tilapia (Elizâ ngela et al, 2019).…”

This study aimed to evaluate the impact of plant-based food additives on growth performance, body composition and survival of Nile tilapia. Four isonitrogenous (25% CP) and isolipidic (13% CL) experimental diets were prepared and designated as R1, R2, R3, and R4. R1 contains (3% Cymbopogon citratus), R2 contains (3% Ocimum basilicum), R3 contains (3% Mentha spicata) and R4 (control or 0% additive). 180 Nile tilapia fry with an initial average weight of 0.2g were distributed in 12 plastic tanks (50 L/tank) at the stocking density of 15 fish per tank in an isolated system. Fish were fed with experimental diets 3 times per day (8:00 am, 1:00 pm and 5 :00 pm) for 3 months. After 90 days of experiment, the results revealed that the final average weight ranged from 2.62g to 8.00g, the absolute average weight gain (AAWG) from 2.42 to 7.8g, the feed conversion ratio (FCR) from 1.31 to 2.67 and specific growth rate (SGR) from 3.06 to 4.36%/d. The survival rate (SR) varied between 64 and 100%. Of the parameters studied such as the absolute average weight gain (AAWG), the specific growth rate (SGR), the feed conversion ratio (FCR), and the survival rate, the best were obtained by the group of fish fed with the R2 diet containing 3% Ocimum basilicum. The results of the analysis of the flesh showed that the addition of 3% O. basilicum does not modify the contents of dry matter, crude protein, and ash but slightly increased the fat content. Based on the results, the inclusion of natural plant-based food additive (3% Ocimum basilicum) in the diet of Nile tilapia improved the parameters of growth, feed efficiency, and survival.

“…Treatment with plant essential oils (EOs) is an environmental‐friendly alternative to antibiotic use in aquaculture (Culot et al., 2019; Romero et al., 2012). In addition to reducing resistance phenomenon (Dugo & Di Giacomo, 2002) and broad‐spectrum antimicrobial activity against fish pathogens, they are considered safe substances with several potential benefits for fish farming, which include the improvement of fish welfare, health and zootechnical performance indices, such as growth performance, feed conversion rate and protein efficiency rate (Acar et al., 2019; De Souza et al., 2019; Sutili et al., 2018). The antibacterial (Vaseeharan et al., 2013), antiparasitic (Da Costa et al., 2017; Metin et al., 2015; Soares et al., 2016) and immunomodulatory (Acar et al., 2019; Sutili et al., 2018; Valladão et al., 2017) effects of EOs help to prevent outbreak of disease in fish farming, therefore minimizing economic loss due to disease and help combat the indiscriminate use of antimicrobials and therefore the emergence of antimicrobial resistance.…”
