“…Although carbohydrates can meet the high energy demand for osmoregulation during salinity stress, high carbohydrate diets may lead to lipid deposition in fish, increasing the risk of fatty liver and disrupting the function of antioxidant systems ( Li et al., 2018 ; Limbu et al., 2020 ; Luo et al., 2020 ). In addition, persistent hyperglycemia usually occurs after high carbohydrate intake in fish, which would lead to liver glycogen deposition, liver cell damage and metabolic disorders ( Li et al., 2020 ; Vinosha et al., 2020 ; Wu et al., 2021 ). The results of this study showed that high dietary carbohydrate increased WG, HSI, and the crude lipid content in tilapia, indicating that high carbohydrates could cause abnormal obesity in tilapia.…”

“…Even though this type of algae has wide potential for use, especially its bioactive compounds. Halymenia is a supply of natural pigments and also contains bioactive components which have been broadly reported, particularly within the last 5 years, specifically as antioxidants, antibacterial, antimalarial, and antiviral (Deepak et al, 2019;Malik et al, 2020;Vinosha et al, 2019;Vinosha et al, 2020). Halymenia sp.…”

This study aimed to determine the antibacterial activity and toxicity of methanol and hexane extracts of Halymenia durvillei red seaweed which were found abundantly in Kayangan island, South Sulawesi. The antibacterial activity of the crude extract was tested against five gram-negative bacteria, namely Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, Aeromonas hydrophila, and Vibrio harveyi at a dose of 200 g/disk. Extract toxicity was tested on Artemia salina larvae at concentrations of 1,000, 500, 250, 125, 62.5, and 31.25 µg/mL. The results showed that the methanol and hexane extracts of H. durvillei had the highest activity against S. thypi and A. hydrophila, respectively, with inhibition zones of 26.2 mm and 21.0 mm. On the other hand, the two extracts did not show activity against E. coli and P. aeruginosa, respectively. The toxicity of the methanol extract of H. durvillei was twice as high as that of the hexane extract with half-maximal inhibitory concentration of 98.24 and 184.21 µg/mL, respectively. Thus, the methanol and hexane extracts of red seaweed H. durvillei have the potential as new antibacterial agents respectively against the pathogenic bacteria S. typhi and A. hydrophila, but also have the opportunity to be developed into antitumor herbal compounds.

“…In rohu, Pal et al(2019) reported that the infection increased the hepatic and splenic GSH levels in 7 dpi and Roy et al(2019) stated that the infection increased the serum GSH levels in 3 dpi. In Nile tilapia, Zahran et al(2018) reported that the infection decreased the muscle GSH levels in 14 dpi and Vinosha et al(2020) reported a decrease in hepatic GSH levels after infection. Therefore, the fish species, the sample collection time and the organ collected interfere with GSH results.…”

“…For example, prophylactic baths (1 h per day for 1 week) of tea tree (Melaleuca alternifolia) essential oil (50 µl l À1 ) prevents oxidative damage in liver of silver catfish experimentally infected with A. hydrophila by preventing the increase in MDA and PC levels (Baldissera et al2017). Vinosha et al(2020) reported that sulphated galactan from red seaweed (Halymenia dilatata) in the feed (20 g kg À1 of feed) for 1 week before infection prevents redox imbalance in tilapia with aeromonosis. Baldissera et al(2019) reported that dietary supplementation with 8% of caffeine for grass carp for 1 month prevents lipid and protein damage caused by aeromonosis.…”

The aim of this review was to summarize the current knowledge regarding the effects of aeromonosis on fish oxidative status. The bibliographic survey was carried out on the research platforms: Scopus and Science Direct. The keywords 'Aeromonas', 'fish' and 'oxidative status' (or 'oxidative stress', 'oxidative damage' and similar terms) were used. Scientific papers and short communications were considered. Studies involving fish aeromonosis and enzymatic or non-enzymatic markers of oxidative status were selected. The results of antioxidant enzymes activities/expressions after infection lack consistency, suggesting that these findings should be interpreted with caution. Most of the analysed studies pointed to an increase in reactive oxygen species, malondialdehyde and protein carbonylation levels, indicating possible oxidative damage caused by the infection. Thus, these three biomarkers are excellent indicators of oxidative stress during infection. Regarding respiratory burst activity, several studies have indicated increased activity, but other studies have indicated unchanged activity after infection. Nitric oxide levels also increased after infection in most studies. Therefore, it is suggested that the fish's immune system tries to fight a bacterial infection by releasing reactive oxygen and nitrogen species.
