“…In this study, the serum lysozyme activity was significantly enhanced in all MLE groups compared to the control group. This finding is consistent with previous studies that demonstrated increased LYZ activity in Nile tilapia after dietary supplementation with M. oleifera extract [ 19 , 25 , 64 ] and extracts from Pisidium guajava and Phyllanthus acidus [ 4 , 65 ]. The diets enriched with MLE are proposed to elevate lysozyme levels, potentially enhancing its effectiveness in targeting the peptidoglycan layer within bacterial cell walls.…”

“…The growing demand for animal protein necessitates intensive culture systems, which, unfortunately, elevate disease risk due to their suboptimal water quality, high stocking density, and abrupt shifts in culture conditions. These conditions amplify stress, triggering various disease agents, primarily from streptococcal bacteria [ 3 , 4 ]. Streptococcosis is a common disease observed in various aquaculture species [ 5 ].…”

The present study aimed to investigate the effects of Moringa oleifera leaf (MLE) extract-supplemented diets on the growth, feed utilization, hematology, innate immune response, and disease resistance of Nile tilapia against Streptococcus agalactiae Biotype 2. Four hundred and fifty Nile tilapia (32.61 ± 0.2 g/fish) were randomly allocated into fifteen tanks (30 fish/tank). Different concentrations of MLE at 0%, 0.5%, 1%, 1.5%, and 2% were fed to the Nile tilapia for 30 days, and the growth, feed utilization, hematology, and innate immune response of the Nile tilapia were determined. After the feeding trial, the Nile tilapia were challenged with a S. agalactiae Biotype 2 infection, and the relative percentage of survival (RPS) was determined. Results revealed the presence of quercetin, kaempferol, and p-coumaric acid in the MLE extract, exhibiting stronger antimicrobial activity against S. agalactiae Biotype 2. The diets supplemented with the MLE-0.5 group showed a significantly higher growth, feed utilization, hematology, and innate immune response in the Nile tilapia compared to the control and other MLE groups. Additionally, the MLE-0.5 group exhibited a significantly higher RPS of the Nile tilapia against S. agalactiae Biotype 2. Therefore, MLE-0.5 can be employed as an alternative feed supplement in sustainable Nile tilapia farming to protect against S. agalactiae Biotype 2.

“…Fish were weighed at the start and end of the experimental period. The final weight, weight gain (WG), specific growth rate (SGR), and feed conversion ratio (FCR) were calculated according to the following standard equations [ 28 ]: WG (%) = 100 × (final mean body weight – initial mean body weight)/initial mean body weight SGR = [(ln (final body weight) – ln (initial body weight)/days] × 100 FCR = feed intake (g)/weight gain (g) ADG = (% gain)/(number of days) …”

The aim of the present study was to evaluate the effects of a Jerusalem artichoke-supplemented diet on the blood chemistry, growth performance, intestinal morphology, expression of antioxidant-related genes, and disease resistance against Aeromonas veronii challenge in juvenile red tilapia. A completely randomized design (CRD) was followed to feed red tilapias with three experimental diets: control, 5.0 g/kg JA-supplemented (JA5), or 10.0 g/kg JA-supplemented (JA10) diets in triplicates for 4 weeks. The results revealed that the growth performance, weight gain (WG), specific growth rate (SGR), and average daily gain (ADG) of fish fed diets JA5 and JA10 were significantly higher (p < 0.05) than those of fish fed the control diet. Fish fed the control diet had significantly higher T-bilirubin, D-bilirubin, and ALT in blood serum than fish fed JA5 and JA10, as well as higher BUN than fish fed JA5. The number of goblet cells in the proximal and distal parts of the intestine revealed that the number of acid, neutral, and double-staining mucous cells of fish fed diets JA5 and JA10 was significantly higher (p < 0.05) than in fish fed the control diet. The diets including the prebiotic (JA5 and JA10) were associated with a significant increase in the expression of gpx1 and gst antioxidant-related genes and disease resistance against A. veronii in juvenile red tilapia. Therefore, JA5 and JA10 can be employed as promising prebiotics for sustainable red tilapia farming.

“…Serum samples were collected and pooled from three fish of each replicate. Fish serum was collected by following the method explained by Kamble et al (2018). Serum ionic concentrations (K + , Na + , Ca 2+ and Mg 2+ ) were analysed in inductively coupled plasma atomic emission spectroscopy (ICP-AES, SPECTRO GmbH, Germany).…”

A trial was conducted to evaluate the effect of graded levels of potassium (K+) amended inland saline groundwater (ISW) on serum ionic composition, antioxidant and metabolic enzymes [Na+/K+ATPase, Catalase, Superoxide dismutase (SOD), Glutathione peroxidase (GPx), Glutathione S-transferase (GST), Lactate dehydrogenase (LDH), aspartate aminotransferase (AST)] activities of silver pompano, Trachinotus blochii (Lacepede, 1801). The ISW was amended with 100% K+ at 5 ppt (ISW5), 10 ppt (ISW10) and 15 ppt (ISW15) and reconstituted seawater (RSW) with similar salinities (RSW5, RSW10 and RSW15) was employed as a reference medium. Experiment was conducted using completely randomised design. T. blochiijuveniles (1.5±0.5 g) were reared in 300 l capacity circular FRP tanks for 90 days. Fish were fed with commercial extruded floating feed. At the end of experimental period, serum ionic composition, enzymatic profiles and proximate composition were estimated. Results of the study showed that the serum ionic content (K+, Na+, Ca2+ and Mg2+) varied dose-dependently with salinity (p<0.05). Na+/K+ATPase, antioxidant enzymes (Catalase and SOD) and metabolic enzymes (GPx, GST, LDH and AST) showed higher activities at lower salinity (ISW5 and RSW5) compared to fish reared at 10 ppt and 15 ppt ISW. Similarly, proximate composition exhibited significantly (p<0.05) lower protein and lipid content at lower salinity (ISW5 and RSW5) signifying the stress condition at lower salinity. Physiological responses of T. blochii in terms of serum ionic composition, enzymatic profile and proximate composition were optimum at 10 and 15 ppt amended ISW, implying that rearing at 10-15 ppt with 100% K+ amendment of inland saline groundwater is appropriate.
