A 120-day growth trial was completed to assess rearing water quality and fish performance in terms of growth, feed efficacy, digestive enzymes, immunity, and antioxidant activity of seabass fed an experimental diet (ED) supplemented with commercial wood charcoal (WC) and activated wood charcoal (AC). Three levels (0, 10, and 20 g) of WC and AC were administered, representing five treatments: control (CD) fish-fed ED without additives, (WC-1) fish-fed ED containing 10 g kg−1 WC, (WC-2) fish-fed ED containing 20 g kg−1 WC, (AC-1) fish-fed ED containing 10 g kg−1 AC, and (AC-2) fish-fed ED containing 20 g kg−1 AC. Three hundred fish (60.12 ± 0.20 g/fish) were stocked in 15 cement tanks (4.0 m × 2.0 m × 1.2 m, water volume 5 m3 each) at 20 fish/tank and a daily feed ration of 3% of body weight. Results revealed significant improvements with increased growth variables (final weight, weight gain, and specific growth rate), decreased FCR, and decreased ammonia levels and heavy metals (Cu, Cd, Fe, Mn, and Zn) content in rearing water, muscle, and liver with fish fed WC and AC supplemented diets. Furthermore, considerable improvements in digestive enzymes, immunity, and antioxidant activity, with enhanced kidneys, liver, intestines, gills, and spleen. Fish fed the WC-1 diet had a higher final weight (171.90 g), better FCR (1.25), and improved internal organs than the other groups.

“…There are three major ways to maximize feed utilization: (1) using feed additives, that is, herbs extracts (El‐Dakar et al, 2008; Hussein et al, 2023), probiotics (M. Abdel‐Aziz et al, 2020; El‐Dakar et al, 2007; Shadrack et al, 2023), exogenous enzymes, and minerals in nanoparticles (Dawood et al, 2019, 2020), (2) establishing feeding strategies (M. F. Abdel‐Aziz et al, 2016; M. Abdel‐Aziz et al, 2020; M. F. Abdel‐Aziz, Abdel‐Tawwab, et al, 2021; El‐Dakar et al, 2021), and (3) providing the optimal environmental conditions for the well‐being of fish to maximize the utilization of each feed molecule added to the water (Abu‐Elala et al, 2023; El Basuini, Teiba, et al, 2022; El Basuini, Zaki, et al, 2022; Teiba et al, 2020).…”

The present work aimed to investigate the impacts of tank color (transparent, light blue, and red), feed pellet types (floating and sinking), and their interaction on the performance and welfare of red hybrid tilapia juveniles with an initial average weight of 19.59 g for a 50 day trial period following a 3 × 2 factorial design. Fish were cultured randomly at a stoking rate of 10 juveniles/100‐L tank. Fish were fed 6 days per week at a rate of 4% biomass twice daily. Three replicates were performed for each measurement. A two‐way analysis of variance showed that using tanks of different colors (transparent, light blue, and red) has no impact on the growth, feed efficacy, survival rate, and blood composition (except for red blood cells, hematocrit, and triglycerides) of tilapia. Also, pellet types (floating and sinking) showed no significant alterations for the above variables except for glucose and hematocrit levels. Interestingly, the interaction between tank color and pellet type exhibited significant impacts on growth parameters, feed utilization, blood variables, and intestinal enzymes of red hybrid tilapia. Moreover, fish reared in transparent or light blue tanks and fed with floating diets performed the best for all evaluated parameters. Additionally, sinking pellets had better effects when combined with red (dark)‐colored tanks.

“…Aquaculture is thought to be a practical way to replace and conserve overfished stocks and endangered fish species, as well as to bridge the gap between production and human demand 1 – 3 . Aquaculture has significantly increased the amount of seafood produced since the 1970s, yet there are still several challenges for the industry.…”

This study investigated the clinical and pathological symptoms of waterborne lead toxicity in wild Nile tilapia collected from a lead-contaminated area (the Mariotteya Canal: Pb = 0.6 ± 0.21 mg L−1) and a farmed fish after 2 weeks of experimental exposure to lead acetate (5–10 mg L−1) in addition to evaluating the efficacy of neem leaf powder (NLP) treatment in mitigating symptoms of lead toxicity. A total of 150 fish (20 ± 2 g) were alienated into five groups (30 fish/group with three replicates). G1 was assigned as a negative control without any treatments. Groups (2–5) were exposed to lead acetate for 2 weeks at a concentration of 5 mg L−1 (G2 and G3) or 10 mg L−1 (G4 and G5). During the lead exposure period, all groups were reared under the same conditions, while G3 and G5 were treated with 1 g L−1 NLP. Lead toxicity induced DNA fragmentation and lipid peroxidation and decreased the level of glutathione and expression of heme synthesis enzyme delta aminolaevulinic acid dehydratase (ALA-D) in wild tilapia, G2, and G4. NLP could alleviate the oxidative stress stimulated by lead in G3 and showed an insignificant effect in G5. The pathological findings, including epithelial hyperplasia in the gills, edema in the gills and muscles, degeneration and necrosis in the liver and muscle, and leukocytic infiltration in all organs, were directly correlated with lead concentration. Thus, the aqueous application of NLP at 1 g L−1 reduced oxidative stress and lowered the pathological alterations induced by lead toxicity.
