“…Several studies reported that essential oils played an important role in promoting the growth performance of fish, which may be a result of sensory stimulation and efficient diet absorption and utilization (Mahmoud et al., 2021; Tartila et al., 2021). Essential oils could modulate the intestinal microbiota, which may show a positive effect on nutrient metabolism and innate immune responses (Zaminhan‐Hassemer et al., 2022). In addition, the dietary essential oils generally improve the meat quality and fatty acid composition of fish (Iniesta et al., 2022; Montanher et al., 2016).…”

This study was conducted to investigate the effects of dietary supplementation of 0%, 0.2%, 0.35%, and 0.5% cinnamon essential oil on growth performance, fatty acid, and fillet quality of tilapia (Oreochromis niloticus). The results of growth experiments showed that the weight gain rate linearly and quadratically increased with increasing cinnamon essential oil doses (p < 0.05). The results of fatty acids experiments showed that the addition of essential oil significantly decreased the saturated fatty acids levels from 36.67% to 30.82% and increased the polyunsaturated fatty acids (PUFA) levels from 24.55% to 46.89%; especially, the n − 3 PUFA of 0.5% essential oil treatment showed the highest levels. Moreover, the n − 6 PUFA of 0.2% essential oil treatment were increased from 22.17% to 32.99%. The results of fillet quality experiments showed that the hardness and cohesiveness were linearly and quadratically increased with the increasing essential oil doses on days 4 and 7, respectively. The b* values linearly and quadratically decreased as the doses increased on day 7 (p < 0.05). The total volatile basic nitrogen levels were quadratically decreased with increasing cinnamon essential oil doses on day 7 (p < 0.05). In general, it can be concluded that cinnamon essential oil presented positive effects on the growth, nutritive values, and meat quality in tilapia.

“…Within this category, essential oils have attracted particular interest due to their complex composition of bioactive compounds, which offer several benefits for fish health and performance [8,9]. One key aspect of essential oils is their antimicrobial actions, which can help maintain healthy gut microbiota and reduce the risk of infections in fish [10,11]. Additionally, their antioxidant activities contribute to attenuating oxidative stress, often associated with intensive cultivation.…”

This study aimed to evaluate the supplementation of peppermint essential oil (Mentha piperita; PEO) in diets for juvenile Nile tilapia (Oreochromis niloticus). A feeding experiment with diets containing graded levels (0.0, 0.2, 0.4, 0.6, 0.8, and 1.0 g kg−1) of PEO was carried out with fish of 0.58 ± 0.08 g. The inclusion of graded levels of PEO in the diet improved the weight gain (0.52 g kg−1), feed intake (0.51 g kg−1), and feed conversion (0.51 g kg−1) of juvenile Nile tilapia in a quadratic pattern. Increasing levels of PEO also led to a linear decrease in body lipid content. The gut activity of the digestive enzymes amylase (0.54 g kg−1) and protease (0.39 g kg−1) increased quadratically, whereas lipase activity increased linearly. PEO increased the activity of the antioxidant enzymes catalase (CAT; 0.52 g kg−1) and superoxide dismutase (SOD; 0.58 g kg−1) while reducing the production of malonaldehyde (MDA; 0.40 g kg−1) and nitric oxide (NO; 0.63 g kg−1) in the liver. The results of this study provide evidence of the beneficial effects of PEO on the growth and health of Nile tilapia and recommend a dose of 0.6 g kg−1 as the optimal level of supplementation.
