“…These results align with previous observations reporting IL-1 and IL-8 upregulation following immunostimulant feeding in tilapia [92]. However, in golden pompano, CH reduced IL-8 expression [57], highlighting species-specific differences. Antioxidant supplements can improve fish health by reducing oxidative stress.…”

“…Glutathione S-transferase (GST) detoxifies electrophiles, enhancing their elimination [94]. In this study, we found dietary CH-supplemented significantly increased antioxidant gene (GSR, GPX, GST-α) expression in tilapia liver and intestine, similar to previous tilapia studies [13] and golden pompano [57]. This suggests that CH may mitigate oxidative damage.…”

“…Interestingly, this study indicated that only the 10 mL•kg −1 CH diet significantly increased FW, WG, and SGR of Nile tilapia fingerlings, suggesting that the benefits are dose-dependent, with excessive amounts conferring no added growth effects. Indeed, multiple studies have evidenced the detrimental impacts of immunostimulant over-supplementation on aquaculture species, including immune exhaustion and slowed growth [57,58]. Shiau and Yu [53] reported decreased weight gain in Nile tilapia with chitosan, potentially due to reduced nutrient digestibility and absorption.…”

Chitosan (CH) shows great potential as an immunostimulatory feed additive in aquaculture. This study evaluates the effects of varying dietary CH levels on the growth, immunity, intestinal morphology, and antioxidant status of Nile tilapia (Oreochromis niloticus) reared in a biofloc system. Tilapia fingerlings (mean weight 13.54 ± 0.05 g) were fed diets supplemented with 0 (CH0), 5 (CH5), 10 (CH10), 20 (CH20), and 40 (CH40) mL·kg−1 of CH for 8 weeks. Parameters were assessed after 4 and 8 weeks. Their final weight was not affected by CH supplementation, but CH at 10 mL·kg−1 significantly improved weight gain (WG) and specific growth rate (SGR) compared to the control (p < 0.05) at 8 weeks. Skin mucus lysozyme and peroxidase activities were lower in the chitosan-treated groups at weeks 4 and 8. Intestinal villi length and width were enhanced by 10 and 20 mL·kg−1 CH compared to the control. However, 40 mL·kg−1 CH caused detrimental impacts on the villi and muscular layer. CH supplementation, especially 5–10 mL·kg−1, increased liver and intestinal expressions of interleukin 1 (IL-1), interleukin 8 (IL-8), LPS-binding protein (LBP), glutathione reductase (GSR), glutathione peroxidase (GPX), and glutathione S-transferase (GST-α) compared to the control group. Overall, dietary CH at 10 mL·kg−1 can effectively promote growth, intestinal morphology, innate immunity, and antioxidant capacity in Nile tilapia fingerlings reared in biofloc systems.

“…CAT further catalyzes the production of H 2 O 2 to H 2 O and O 2 , which in turn protects the organism [38]. The T-AOC includes the body's antioxidant enzyme system and nonenzymatic system, which respond to the compensatory capacity of external stimuli and the state of the body's free radical metabolism, and its main role is still to scavenge the ROS produced during metabolism [39,40]. In this experiment, both SOD and CAT enzyme activities were the highest in the high-frequency group, indicating that the body has a strong response to high-frequency shaking stress, and the body secretes more SOD and CAT enzymes to scavenge ROS to ensure that the body is protected from antioxidant damage.…”

In this study, we sought to characterize the effect of water vibration frequency stress on crimson snapper (Lutjanus erythropterus) survival to determine an optimal transportation speed. To achieve this, we used a transport tank (25 cm × 17 cm × 16 cm) to simulate the transport process. After 8 h at five different vibration frequencies (D1 = 75 rpm, D2 = 105 rpm, D3 = 135 rpm, D4 = 165 rpm, and D5 = 195 rpm), the pH and dissolved oxygen (DO) levels in the tanks decreased; ammonia nitrogen levels (NH4-N) and temperature (T) increased with increasing density; and significant changes in oxidative stress biomarkers, digestive enzymes, and ATPase levels were observed in crimson snapper fry. The enzyme activity increased and reached the maximum value at 195 rpm. The experimental results suggested that during the actual transport, when using transport tanks, the length of the transport time was less than 8 h, and setting the vibration frequency for transportation at 135 rpm was more appropriate, that is, a speed of 50 km/h for transporting crimson snapper fry.

“…Empirical evidence has substantiated chitosan's myriad benefits on fish including augmenting growth performance (Imefon Udo, 2018; Maqsood et al, 2010; Wu, 2020), fortifying immune response (Chen & Chen, 2019; Harikrishnan et al, 2012; Lin et al, 2012), cholesterol mitigation (Yu et al, 2023) and antioxidant promotion (El‐Naggar et al, 2021). Additionally, chitosan positively modulates intestinal morphology (Chen et al, 2014), and its marine‐derived extraction aids in curbing environmental pollutants (Abd El‐Naby et al, 2019).…”

As sturgeon breeding has proliferated, there has been a heightened demand for growth stimulators in their diets. This study aimed to determine the impact of dietary chitosan on growth performance, whole‐body proximate composition, growth‐related gene expression, and intestinal histology in juvenile Acipenser stellatus. A total of 180 A. stellatus juveniles with an average weight of 31.90 ± 0.73 g were fed with diets containing 0 (control), 1.5, 3.0, 4.5, and 6.0 g chitosan.kg−1 basic diet for eight weeks. The findings revealed a significant enhancement in growth performance with rising chitosan concentrations. Furthermore, chitosan supplementation upregulated the expression of the growth hormone gene in both brain and liver tissues. In liver samples, the most pronounced expression of the insulin‐like growth factor‐1 gene was noted at 6.0 g chitosan.kg−1, while in brain samples, peak expressions were observed in both the 4.5 and 6.0 g chitosan.kg−1 treatments. While the whole‐body proximate composition remained relatively stable, there was a notable decrease in whole‐body lipids with the escalation of chitosan dosage. Intestinal villi dimensions, both height and width, were amplified in the chitosan‐supplemented groups compared to controls. In summation, chitosan supplementation showed promise in bolstering growth performance, refining intestinal morphology, and enhancing growth‐related gene expression. Analysis of the polynomial regression of weight gain and specific growth rate revealed that the optimum dietary chitosan requirements in A. stellatus were 5.32 and 5.21 g chitosan.kg−1, respectively.
