“…However, exposure to stress can trigger metabolic shifts necessary to meet the increased energy demand, leading to heightened production of ROS as by-products of cellular respiration and other metabolic processes. Oxidative stress occurs when there is an imbalance between the production of ROS and the antioxidant scavenging capacity of tissues through the action of antioxidant enzymes (e.g., SOD, CAT, GPx, GST, and GR), resulting in cellular membrane lipids damage [38,39]. In the liver of fish fed diets completely devoid of FM, the activity of SOD was increased, underscoring the significance of this adaptive response and highlighting its crucial role in antioxidant defence mechanisms.…”

This study aimed to explore the effect of FM substitution by defatted Tenebrio molitor larvae meal (dTM) on the response of European seabass to an acute stress challenge. An FM-based diet was used as a control and two other isoproteic/isoenergetic diets were formulated to replace 50 and 100% of FM by dTM. Each diet was tested in quadruplicate groups of 15 fish (69 ± 5 g) fed until visual satiety for 16 weeks. After the feeding trial, fish were subjected to 1 min air exposure followed by 1 h of recovery before sampling. The haematological profile, plasma metabolites, and humoral immunity biomarkers, as well as hepatic oxidative stress and antioxidant capacity, were analysed. A clear response to acute stress was observed by a significant increase in haemoglobin, haematocrit, red blood cells, and almost all evaluated plasma metabolites and humoral parameters, regardless of dietary treatment. The obtained results demonstrated that partial substitution of FM by IM did not affect the stress response of seabass. However, total FM replacement increased the hepatic activity of total peroxidase and superoxide dismutase in fish fed TM100.

“…In the domain of aquatic ecosystems, prioritizing the vitality and thriving of fish populations takes precedence. A pivotal determinant influencing fish well-being is oxidative stress [1], a condition characterized by the disproportion between the generation of detrimental reactive oxygen species (ROS) and an organism's capacity to mitigate their injurious consequences through antioxidants [2]. This intricate equilibrium plays a vital role in upholding the comprehensive health and efficiency of fish, underscoring the significance of researching antioxidants as a fundamental constituent of fisheries science and aquaculture management [3,4].…”

Fish, constantly exposed to environmental stressors due to their aquatic habitat and high metabolic rates, are susceptible to oxidative stress. This review examines the interplay between oxidative stress and fish reproduction, emphasizing the potent antioxidant properties of astaxanthin. Our primary objective is to highlight astaxanthin’s role in mitigating oxidative stress during critical reproductive stages, leading to improved gamete quality, ovary development, and hormone levels. We also explore its practical applications in aquaculture, including enhanced pigmentation and overall fish health. We conducted a comprehensive literature review, analyzing studies on astaxanthin’s antioxidant properties and its impact on fish reproduction. Astaxanthin, a carotenoid pigment, effectively combats reactive oxygen species, inhibiting lipid peroxidation and maintaining membrane integrity. It significantly enhances reproductive success in fish and improves overall fish health in aquaculture settings. This review reveals astaxanthin’s multifaceted benefits in fish health and reproduction, offering economic advantages in aquaculture. Future research should delve into species-specific responses, optimal dosages, and the long-term effects of astaxanthin supplementation to inform sustainable aquaculture strategies.

“…Under regular metabolic circumstances, animal cells constantly produce reactive oxygen species (ROS); however, an imbalance between ROS production and elimination can harm the body(Snezhkina et al, 2020). The body has devised numerous antioxidant defense strategies to manage ROS production effectively(Wu et al, 2022: Song et al, 2023. Among these mechanisms are a range of antioxidative enzymes such as SOD and MDA.…”

This experiment aimed to examine the potential of distillers dried grains soluble (DDGS) meal as a substitute for soybean meal (SBM) in the Paci c shrimp diet. The study aimed to investigate how DDGS affected disease resistance, antoxidation, and gut microbiota. 840 shrimp were given varied diets with varying concentrations of DDGS. D1 (0%), D2 2%, D3 4%, D4 6%, D5 8%, D6 10%, and D7 12% were the DDGS levels. Each group had three replicates of the 56-day experiment. Initially, the weight was 0.19 ± 0.00 g. The survival rate was consistently 100% for shrimp-fed DDGS, except for group 7 (14%) and the control group, where shrimp mortality was observed. The total protein (TP) content was improved as the inclusion level of DDGS increased. The glucose (GLU) exhibited a downward trend with higher DDGS inclusion.Similarly, the TG and CHO levels in the serum decreased as the DDGS levels increased. The activities of ALT (alanine transaminase) and AST (aspartate aminotransferase) decreased as the dietary DDGS increased, with the control group showing signi cantly higher ALT and AST activities than those fed DDGS diets (P < 0.05). Furthermore, the SOD (superoxide dismutase) activity signi cantly increased with higher DDGS levels, while the MDA (malondialdehyde) activity showed the opposite trend. Notably, the control exhibited the highest MDA activity value. The most prevalent phylu found in the gut microbiota were Proteobacteria, and Bacteroidetes. Upon completion of a 7-day bacteria challenge, it was observed that shrimp fed with the control diet had a lower mortality rate compared to those fed the DDGS diet. Based on the parameters measured in this study, it was determined that replacing 10% of SBM with DDGS in the feed of Paci c shrimp is feasible. The calculation for shrimp survivalSurvival rate % = [100× End number of shrimp/ Initial number of shrimp] Serum biochemical analysisThis study set out to look into the antioxidant activity and serum biochemical parameters of Paci c shrimp. The levels of TG, CHO, GLU, TP, ALT, AST, MDA, and SOD were among the many activities that our team examined. We used assay kits from the prestigious Nanjing Jiancheng Bioengineering Institute in China to guarantee precise and trustworthy results. We used commercial assay kits from the Nanjing Jiancheng Institute in Nanjing, China, to measure ALT and AST levels. The biuret method was used to determine TP levels. SOD activity was measured using the nitro blue tetrazolium reaction, with the color extracted into butanol and measured at 550 nm. The TBA (thiobarbituric acid) test was used to measure the amount of MDA in the hepatopancreas. Lipid hydroperoxide breakdown was also measured using TBA, resulting in red chemicals at the 532 nm absorbance peak. The analysis of digestive enzymeTo conduct a thorough analysis, we studied how dietary DDGS affects the activity of digestive enzymes, speci cally amylase, lysine, and protease, in shrimp. We selected three shrimp for each group and carefully removed and dissected their intestines. The intestine...
