Nile tilapia Juveniles (19.50 ± 0.5 g) were fed on a basal diet (control group (CTR)) and supplemented with 1 g Aspergillus oryzae (ASP) per kg for 12 weeks. Fish then subjected to different salinity levels (0, 10, 15, 20 practical units (psu)) another 15 days. Two-way ANOVA analysis revealed that the individual effects of ASP in exposed presented significant decrease (p < 0.05) values haemato-biochemical indices (such as glucose, cortisol, alanine transaminase, aspartate malondialdehyde)...
Aeromonas hydrophila infection is one of the major diseases that cause inflammation and immunodepression in aquatic animals. Likewise, waterborne toxins are known for their negative impact on immunity antioxidant responses organisms. In this study, Lactobacillus plantarum (LP20) was incorporated Nile tilapia, Oreochromis niloticus , diets (50 mg/kg) to investigate its role capacity, immunity, anti-inflammation induced by deltamethrin (DLM) toxicity (96-h LC 50 14.9 μg/L) A. (LD 2 × 10 8...
The optimal water temperature for the normal growth of Nile tilapia is between 26 and 28 °C, toxicity pesticides strongly related to temperature. An alternate approach augmenting resistance fish ambient low via synbiotic feeding was proposed. In this study, were allocated into four groups with 10 in each replicate, where they fed a basal diet or synbiotics (550 mg/kg) kept at suboptimal (21 ± 2 °C). prepared diets 30 days without deltamethrin (DMT) exposure (15 μg/L). named control (basal...
The objective of this study was to evaluate the beneficial effect Saccharomyces cerevisiae (SC) on growth, intestinal morphometric characteristics, blood indices, redox balance, expression immune-related genes, and their involvement in disease resistance sea bream (Sparus aurata). Three hundred healthy fingerlings were allocated into equal four groups (15 fish per hapa). first group served as a control received basal diet, while other three fed diets containing 1, 2, 4 g/kg diet SC,...
Olive leaves are an immense source of antioxidant and antimicrobial bioactive constituents. This study investigated the effects dietary incorporation olive leaf extract (OLE) on growth performance, hematobiochemical parameters, immune response, defense, histopathological changes, some growth- immune-related genes in common carp (Cyprinus carpio). A total 180 fish were allocated into four groups with triplicate each. The control group received basal diet without OLE, while other three fed a...
The study aimed at evaluating the possible feeding strategies of selenium (Se) nanoparticles on performances European seabass (Dicentrarchus labrax). first group fed basal diet continuously (control) while second offered Se (1 mg/kg diet) every day (R1). third one then other (R2), and fourth for two days (R3). FBW, WG, SGR were significantly improved in R1 than fish groups (P < 0.05). FCR was reduced by to R1, R2, R3 control with lowest being had enhanced values Hb, RBCs, WBCs Additionally,...
In this study, a sustainable and eco-friendly method was used to prepare zinc oxide nanoparticles (ZnO-NPs) using sea cucumber aqueous extract. Then, ZnO-NPs were characterized by instrumental analysis (UV-vis, HR-TEM, XRD, FT-IR, DLS) evaluated for their possible antibacterial, antifungal, insecticidal activities. Additionally, the toxicity of in vivo against Nile Tilapia (Oreochromis niloticus). The collected from Gulf Suez (Red Sea) at Al-Ain Al-Sokhna coast Egypt identified as Holothuria...
Seaweed liquid extracts are an attractive source of phytochemicals with high potential applicability in the aquafeed-additive industry. A commercial seaweed extract (True Algae Max, TAM®), which has a marine odor, also dislplays significant levels polysaccharides, phytochemicals, phenolic, and flavonoid compounds showing antioxidant activities DPPH inhibition. This study investigates impact diets supplemented TAM® as functional additive on growth, nutrient utilization, immune responses,...
In the last years, there were some bacterial outbreaks occurred during summer season of farm-raised Oreochromis niloticus at Kafr El-Sheikh and Dakahlia Governorates resulting in high fish mortalities severe economic losses these farms. So, this study aimed to detect causes governorates facilitate diagnosis methods pathogens. Thirty farms surveyed (20 10 Dakahlia). 150 examined diseased (five from each farm) succumbed for bacteriological isolation biochemical molecular identification. LD50...
Tick and tick-borne pathogens are among the major threats to animal health production causing huge economic losses in form of morbidity mortality throughout world.Due scarcity epidemiological data appropriate diagnostic methods, study was carried out detect Anaplasma marginale Theileria annulata from buffaloes Sheikhupura, Jhang, Rawalpindi districts by using duplex PCR.A total 1,152 blood samples were screened for investigations.DNA extracted used amplification msp1β gene cytochrome b...
Abstract The concept of probiotics is widely applied in the field aquaculture for their beneficial and friendly influences. In this sense, role Saccharomyces cerevisiae on growth, immune antioxidative responses European seabass was tested study. Fish were distributed 3 groups (triplicates) with ten fish each replicate fed 0, 1, 2 g/kg S. (15×10 9 CFU/g) 90 days. showed higher final body, weight gain, specific growth rate as well lower FCR than basal diet (P<0.05). RBCs, WBCs, Hb, PCV...
The marine environment is a rich source of bioactive compounds. Therefore, the sea cucumber was isolated from Red Sea at Al-Ain Al-Sokhna coast and it identified as surf redfish (Actinopyga mauritiana). aqueous extract utilized an ecofriendly, novel sustainable approach to fabricate zinc oxide nanoparticles (ZnO-NPs). biosynthesized ZnO-NPs were physico-chemically characterized evaluated for their possible antibacterial insecticidal activities. Additionally, safety in non-target organism...
The current study was designed to evaluate the ameliorative effect of lipopolysaccharides (LPS) (a portion Gram –ve bacteria cell wall) on aflatoxin (AFB1)-persuaded changes in cytokine expression, heat-shock protein 70 (HSP70), antioxidant genes, different haematological and biochemical parameters Nile Tilapia along with infection by Aeromonas hydrophila immune-stimulant efficiency LPS growth pattern. For this study, two hundred forty O. niloticus (35 ± 1.5 g) were used. fish randomly...
Abstract Background Fish farming is one of the most productive economies in world. One essential goals fish production to minimize processing costs while maintaining and increasing vital functions, weight immunity fish. Objective We conducted this study explore nanoselenium (Nano‐Se) particles various feeding schemes. Material Method Nano‐Se incorporated basal diet at (0.5 mg/kg diet), was divided into six groups after adaptation as follows: The first group feed daily with a containing...
Abstract The main objective of the current trial was to investigate impacts tilapia diets supplemented with S-methylmethionine sulfonium chloride (MMSC) on growth performance, feed efficiency, body analysis, blood biochemistry and regulation myostatin ( MSTN ) insulin-like factor-1 IGF-1 genes nile Oreochromis niloticus ). experimental fish n =180) weighing 22.4±0.17 g were allocated randomly into three equal groups in triplicate as follows; control group received an un-supplemented diet;...
Knowledge of how fish respond to starvation periods could provide a basis for improved nutrition, rearing, disease control and thereby help optimize Oreochromis niloticus culture. In the current study, effect alternative starvation-re-feeding regime was monitored on some growth, hematological serum biochemical parameters in Nile tilapia fingerlings; followed by checking role these feeding schedules combating challenge.
