“…The present study indicated that the best morphometry of the intestine, crypt depth, and goblet cell count, in current the experiment, were recorded in the fish groups fed on diets supplemented with PRO-F ® and Yeast Plus ® . The elevation of intestinal villus height/length relative to the control group showed a statistically significant improvement that could increase surface intestinal absorption, boost nutrient absorption, and consequently improve growth efficiency ( Sun et al, 2010 ; Pirarat et al, 2011 ; Yossa et al, 2018 ; Khalil et al, 2019 ).…”

“…Similarly, high stocking density decreased the thickness of musculosa layer of Nile tilapia intestine (Abdalqadir, 2014), and size and number of the goblet cells of channel catfish intestine (Refaey et al., 2018). Feeding and nutrition strategies could relieve or overcame these pathological aspects caused by crowding stress and maintained the normal histostructure (Khalil, Mansour, Goda, & Omar, 2019).…”

In China, the in‐pond raceway system (IPRS) recirculating culture is a new model of freshwater aquaculture. A 120‐day feeding study was carried out to evaluate the influence of stocking density on growth, digestive enzymes activity, serum parameters, antioxidant status, liver and intestine histology and gene expression of HSP70 and Cu/Zn‐SOD of largemouth bass farmed in IPRS. Largemouth bass, Micropterus salmoides (initial body weight, 4.50 ± 0.23 g), were randomly farmed in nine raceways stocked at three stocking densities of 0.2 (LSD), 0.4 (MSD) and 0.6 (HSD) kg/m3, and sampled at 30, 60, 90 and 120 days. The results showed that body weight, specific growth rate and weight gain of fish farmed at MSD group were higher than that farmed at LSD and HSD treatments on 30 days (p < 0.05), while fish farmed at MSD and HSD treatments had significantly lower growth than those farmed at LSD groups on 90 and 120 days (p < 0.05). There were no significant differences in serum cortisol, glucose and triglyceride levels among three groups on 30, 60 and 90 days (p > 0.05), whereas fish farmed at HSD group had significant higher values than that farmed at LSD group on 120 day (p < 0.05). There were no significant differences in serum lysozyme level on day 30, while it decreased with increasing stocking densities on after day 60. Fish reared at LSD group had significantly higher SOD activities than those farmed at MSD and HSD treatments, and had significantly higher CAT activities than those farmed at HSD group on 120 day (p < 0.05). MDA level increased with increasing stocking density on days 60, 90 and 120 (p < 0.05). Fish farmed at HSD group had significantly higher liver HSP70 mRNA levels on days 90 and 120 (p < 0.05). Cu/Zn‐SOD mRNA levels showed a downward trend. No significant difference was observed on liver and intestine histology (p > 0.05). In conclusion, largemouth bass farmed at 0.4 kg/m3 had better growth and health status before days 30. After that, fish farmed at higher stocking densities in IPRS would inhibit growth and reduce immune function.

“…The improvement of growth performance, feed utilization, and physiological status of cultured fish is a way to maximize economic revenue [4,56]. This target has a great impact on the establishment of farming emerging aquaculture species, such as rabbitfish, S. rivulatus [39].…”

“…Global aquaculture production has been on a continuous rise to cover the increase in the global consumption of aquatic animals due to rapid population growth and consumer awareness of the decline/deterioration of natural fisheries [1]. Presently, the marketing of aquatic products, considering the nutritive values, especially antioxidant levels, fatty acid profile, and trace element content, highlights their use as functional foods [2][3][4][5]. Carotenoids are one of the preferred supplements, as a natural pigment, to be delivered via aquatic products to improve general body performance and some specific functions, including ocular integrity [6,7].…”

A 60-day feeding trial was conducted to assess the effects of dietary supplementation with bile salts (BS), lutein (LTN), and their combination on growth, survival, carotenoid content, and antioxidant status of rabbitfish (Siganus rivulatus) larvae. Fish were fed four isonitrogenous (34.39% protein) and isoenergetic (20.57 kJ/g) diets supplemented with BS (0.15 g kg−1), LTN (0.1 g kg−1), BS+LTN (0.15 and 0.1 g kg−1, respectively), and a non-supplemented control diet. The results revealed that fish fed BS+LTN had the highest significant specific growth rate (4.37% day−1), feed efficiency (46.55%), and survival (97.78%). Lutein supplementation improved whole-body protein content, meanwhile, fish fed a BS-supplemented diet had a higher lipid content. The carotenoid deposition was significantly increased with LTN and BS+LTN in skin, muscle, and whole body compared to the control and BS treatment. All dietary supplementation of BS and LTN showed significant improvement in total antioxidant capacity, catalase, and glutathione peroxidase activities. Additionally, LTN alone or BS+LTN significantly reduced malondialdehyde levels by 5.30 and 29.91%, respectively compared to the control. BS supplementation modulated aminopeptidases activities, triglycerides, cholesterol, and increased the activity of pancreatic lipase. Therefore, it could be inferred that dietary supplementation with LTN in combination with BS could improve the growth performance, carotenoid deposition, antioxidant status, lipid digestion, and metabolism of S. rivulatus.
