“…Phytol has been demonstrated to possess antioxidant properties [74]; a study on common carp has shown that dietary phytol can induce hepatic antioxidant enzymes and mitigate ammonia-induced lipid peroxidation [16]. It has been demonstrated that the incorporation of antioxidant phytochemicals, such as turmeric [10], or other antioxidants, such as ascorbic acid [75] and glycine [76], into the diet of fish can enhance antioxidant capacity and mitigate posttransportation oxidative stress. The antioxidant responses before and after transportation indicate that 75 and 150 mg/kg phytol can support the antioxidant system and suppress lipid peroxidation.…”

Nile tilapia, Oreochromis niloticus, (2.00 ± 0.02 g) were reared in 16 70-L tanks (40 individual/tank) and fed diets (approx. 345 g/kg protein, approx. 87 g/kg crude fat) containing 0 (CTL), 75 (PH-75), 150 (PH-150), and 300 (PH-300) mg/kg phytol (n = 4). After 60 days of feeding (4% daily), growth performance, humoral immune parameters, and gut bacteria were analyzed. Also, hepatic antioxidant parameters were determined before and after the fish were transported in plastic bags for 6 hr. The results showed that PH-75 exhibited the highest final weight (P<0.001), weight gain (P<0.001), feed intake (P<0.001), feed efficiency (P=0.015), plasma lysozyme activity (P=0.004), and intestinal Lactobacillus sp. population (P=0.017), among the treatments. The highest plasma alternative complement activity (P=0.006) and the lowest intestinal total viable bacteria (P=0.027) were observed in PH-75 and PH-150. The highest plasma alkaline phosphatase activities were observed in PH-75 and PH-300 (P=0.014). The highest blood leukocyte (P=0.008), monocyte (P=0.010), and eosinophil (P<0.001) were observed in PH-300, while the highest blood neutrophil was observed in all phytol treatments (P<0.001). The highest hepatic lipid peroxidation was observed in PH-300, whereas PH-75 and PH-150 showed the lowest values (P<0.001). The highest hepatic reduced glutathione was observed in PH-75, also PH-150 exhibited significant elevation in this parameter, compared to CTL (P<0.001). Transportation led to significant elevations in the hepatic antioxidant enzymes’ activities in CTL, PH-75, and PH-150; the highest activities were related to PH-75 and PH-150 treatments, which had also the highest post-transportation survivals (P<0.001). In conclusion, phytol is a suitable feed supplement for Nile tilapia, improving growth performance and welfare, particularly at 75 mg/kg.

“…Phytol has been found persuading antioxidant properties (Islam et al 2018) and a study on common carp has been shown that dietary phytol can induce hepatic antioxidant enzymes and suppress ammonia-induced lipid peroxidation (Hoseini et al 2021). It has been found that adding antioxidant phytochemicals, such as turmeric (Hoseini et al 2022b), or other antioxidants, such as ascorbic acid (Peng et al 2013) and glycine (Hoseini et al 2022a), to sh diet can increase antioxidant capacity and decrease oxidative stress post-transportation. Based on the antioxidant responses before and after the transportation, dietary 300 mg/kg phytol was harmful for Nile tilapia as it suppressed the GPx and GR activities, thereby increasing lipid peroxidation.…”

In this study, Nile tilapia, Oreochromis niloticus, fingerlings (2.00 ± 0.02) were fed diets (crude protein 345 g/kg; crude lipid 86.8 g/kg) containing 0 (CTL), 75 (PH-75), 150 (PH-150), and 300 (PH-300) mg/kg phytol for 60 days, at 4% of biomass. The fish were reared in sixteen 70-L tanks (n = 4, each with 40 fish). After 60 days rearing, the fish were subjected to 6-h transportation to monitor the hepatic antioxidant parameters. The results showed that dietary 75 mg/kg phytol significantly improved fish growth (P < 0.001) and feed efficiency (P = 0.015). Plasma lysozyme (P = 0.004) alternative complement (P = 0.006), alkaline phosphatase (P = 0.014) significantly increased in PH-75, 75PH/150PH, and PH-75/PH-300 treatments, respectively. All phytol-treatments led to significant (P = 0.001) increase in the blood neutrophil count. The PH-300 treatment resulted in significantly higher blood WBC (P = 0.008), monocyte (P = 0.010), and eosinophil (P < 0.001) counts, compared to CTL. Phytol also modulated intestinal microbiota by reducing the number of total viable bacteria in PH-75 and PH-150 (P = 0.027) and increasing lactic acid bacteria in PH-75 (P = 0.017). PH-75 and PH-150 had highest survival, antioxidant enzymes, reduced glutathione levels, lowest lipid peroxidation, before and/or after the transportation. PH-300 treatment showed an elevation lipid peroxidation, after the transportation. These findings suggest that dietary phytol may be a good supplement for improving the health and growth performance of Nile tilapia, and the recommended level is 75 mg/kg.

“…The oxidative stress induced by transportation may result in mitochondrial dysfunction, because ROS are mainly formed by the mitochondrial electron transport chain in cells [ 31 ]. The observed changes in antioxidant enzyme activities and MDA levels revealed that fish experienced oxidative stress during transport, and that the antioxidant system, although activated, failed to fully neutralize free radicals and other pro-oxidants with prolonged transport times [ 32 ].…”

Live fish are often transported in aquaculture. To explore the effects of transport stress, hybrid yellow catfish (Tachysurus fulvidraco♀ × Pseudobagrus vachellii♂) were subjected to simulated transport treatments (0–16 h) with 96 h of recovery after the 16-h transport treatment, and intestinal biochemical parameters, the transcriptome, and gut microbiota were analyzed. Transportation affected the number of mucus cells and led to oxidative stress in the intestine, which activated immune responses. Changes in lipid metabolism reflected metabolic adaptation to oxidative stress. Toll-like receptor signaling, peroxisome proliferator-activated receptor signaling, and steroid biosynthesis pathways were involved in the transport stress response. Gene expression analyses indicated that transport-induced local immune damage was reversible, whereas disordered metabolism recovered more slowly. A 16S rDNA analysis revealed that transport stress decreased the alpha diversity of the gut microbiota and disrupted its homeostasis. The dominant phyla (Fusobacteria, Bacteroidetes) and genera (Cetobacterium, Barnesiellaceae) were involved in the antioxidant, immune, and metabolic responses of the host to transportation stress. Correlation analyses suggested that gut microbes participate in the transport stress response and the host–microbiota interaction may trigger multiple events in antioxidant, immune, and metabolic pathways. Our results will be useful for optimizing transport processes.
