Abstract The present study tested the symbiotic effects of dietary multi-strain Bacillus probiotics (MSB) ( licheniformis , B. pumilus and subtilis ) in Nile tilapia Oreochromis niloticus exposed to Aspergillus flavus infection. Furthermore, this investigated water quality, growth performance, blood metabolites, histological morphology, immune regulatory genes, resistance A. For 70 days, fish n = 240) were divided into four groups triplicate: T0 (control group; MSB0), T1 (1 g/kg, MSB1), T2...
Abstract Prebiotics are fibers that promote beneficial gut bacteria and play a pivotal role in enhancing host health. This study delves into the impact of various levels prebiotics, specifically fructooligosaccharides β-1,3 glucan (Fβ), on growth performance, biochemical, hematological parameters, gene expression, histological variations internal organs, disease resistance to Fusarium oxysporum tilapia ( Oreochromis niloticus ). Two hundred forty Nile tilapia, initially weighing 34.0 ± 0.1...
Probiotics are becoming increasingly popular as eco-friendly alternatives in aquaculture. However, there is limited research on their impacts the reproductive efficiency of Red Tilapia (Oreochromis niloticus x O. mossambicus) broodstock. Therefore, this experiment aimed to explore combined effects selective probiotics Bacillus subtilis and B. licheniformis (BSL; 1:1) added water blood hematology, serum metabolites, gonadal histology, performance, associated genes broodfish weighing 140-160 g...
Recently, global demand for seafood such oysters is increasing as consumers seek healthy and nutritive alternatives to a diet dominated by animal protein. This trend attributed the growing interest in sustainable strategies surge customer demand. Despite being one of most promising seafoods, oyster industry faces various challenges, increased infectious diseases promoted climate change, pollution, environmental burdens. Hence, industry’s current challenges must be addressed ensure long-term...
Abstract The present study investigated the effect of Chlorella vulgaris on growth performance, feed consumption, body composition, and immune response white shrimp ( Litopenaeus vannamei ) against Vibrio parahaemolyticus infection. Shrimps (4.00 ± 0.04 g) were divided into five groups (3 replicates/20 each) in 15 hapa (1 m 3 cultured for 56 days with C. experimented diets at different concentrations (0, 15, 20, 25, 30 g/kg feed). Growth utilization, biomass, composition (protein, lipid,...
Biofloc (BF) stands out as a promising system for sustainable shrimp farming. Optimizing various culture conditions, such stocking density, carbohydrate source, and feeding management, is crucial the widespread adoption of BF system. This study compares growth performance white-leg (Litopenaeus vannamei) in ponds at low density (LD) with 50 organisms/m2 high (HD) 200 organisms/m2. Post-larvae were stocked 16 weeks both LD HD groups. The group exhibited superior survival rate, feed...
Shrimp culture is quite important and popular across the world. This study aimed to evaluate growth-promoting potential of synthesized selenium nanoparticles from Spirulina platensis extract (SP-SeNPs) as a food source for Pacific whiteleg shrimp (Litopenaeus vannamei). However, pollution considered significant element affecting health development. The effectiveness SP-SeNPs in alleviating negative effects cadmium toxicity was also evaluated. Firstly, shrimps (about 120 individuals with 6.0...
The present study evaluated the influence of different commercial agricultural by-products as a carbon source in bifloc-based (BFT) culture system on growth performance, whole-body proximate composition, digestive enzyme activities, gut microbial abundance, and hepatopancreas histology Pacific whiteleg shrimp, Litopenaeus vannamei post larvae (Pls). Three groups were designed, first group was control group, where shrimp reared clear water (without addition exchange rate 100% two times week)...
Abstract Currently, the aquaculture industry is challenged with disease outbreaks and pathogen infections using intensive production, to mitigate these challenges. Using phytogenic natural compounds as dietary curcumin nanoparticles that have been extensively applied in aquafeeds enhance performance, antioxidant activity, innate immunity of several fish species. The present study investigates response white-leg shrimps ( Litopenaeus vannamei ) Fusarium solani fed on (C-NPs) growth, digestive...
Five treatments including control and four concentrations of water soluble fraction (WSFs) crude oil (5 ppm, 6 8 ppm 10 ppm) were made. Triplicate ten fish red tilapiawith an average weight 8g ± 1.5 incubated for 96 hours. The hours LC50 was determined (5.25ppm). Histopathological examination the made liver, gills, kidney, male gonad female gonad. Liver showed congestion blood vessels hepatic sinusoids with focal necrotic changes hepatocytes. Gills vessels, hyperplasia adhesion secondary...
Abstract A 90-day experiment was carried out to study the influence of biofloc system on water quality, growth, feed utilization, survivability, bacteria in fish gut, and physiological immunological responses thin-lipped mullet ( Liza ramada ). Two treatments, clear (CW) (BFS), were each designed triplicates. Both treatments stocked with (mean weight 1.18 ± 0.02 g). BFS group showed highest final body weight, gain, average daily specific growth rate, lowest conversion ratio, protein...
After determination of LC50, sublethal concentration water soluble fractions (WSFs) petroleum crude oil -quarter LC50- and same zinc selenium '1.3 mg/l was used to study their effects on reproduction profile hybrid red tilapia. The experiment continued for 2 months the groups were "control, WSFs oil, zinc, selenium, zinc+ selenium+ oil". Triplicates each treatment established fish fed twice/daily commercial diet 30% protein. By experiment's end, sex ratio calculated, gonads obtained...
Crustacean decapods form a significant and important component of commercial fisheries in the region Suez Gulf.Current investigation was carried out mainly to examine reproductive system blue swimmer crab's (Portunus pelagicus) males females.Samples Blue crab were collected from Gulf.Histological sections applied confirm morphological stages females' gonads.The results obtained showed that both gonads P. pelagicus like other decapod crustaceans.Male Portunus is bilaterally symmetrical,...
