“…The clinical signs, postmortem and histopathologial signs that appeared on O. niloticus post challenged with A. flavus were in accordance with Abd El Ghany and Elias (2014). The experimental inoculation of O. niloticus with A. flavus indicated that it is highly pathogenic as the cumulative mortality was 100% in the challenged control group within the first 7 days post inoculation.…”

“…Fungi are opportunistic pathogens When infecting freshwater fish, they may cause high mortalities, hinder the growth rate and reduce hatchability especially in chronic infection, including mycotoxins production when fish are subjected to stress of any type such as poor water quality (Abd El Ghany & Elias, 2014;Abd El-Tawab et al, 2020;Noor El-Deen et al, 2018). One of the feed contaminants is the Aspergillus species, which produces aflatoxins (Ferreira et al, 2013).…”

The study aims to investigate the potential effect of nanocurcumin as feed additive in the diet of Oreochromis niloticus to improve its growth performance, health status and resistance against Aspergillus flavus. The control group was fed on a basal diet without nanocurcumin, and four diets T1, T2, T3 and T4 were supplemented with 10, 25, 40 and 55 mg/kg of nanocurcumin, respectively, in triplicate (20 fish/replicate). The duration of the feeding trial was 60 days. The final body weight, weight gain, specific growth rate and survival rate showed significantly (p < 0.05) increased values in the nanocurcumin groups than the control. Fish fed with nanocurcumin supplementation showed improvement in RBCs, haemoglobin, total protein, albumin and globulin while there was a decrease in the liver enzymes (AST and ALT), glucose and alkaline phosphatase. The creatinine was also decreased in fish fed nanocurcumin. The digestive enzymes amylase and lipase increased in the nanocurcumin‐treated groups, and the triglycerides values showed non‐significant increase, whereas the cholesterol values showed non‐significant decrease in T1 and T4. Meanwhile, the cortisol was nearly the same in all groups. At the end of the trial, the fish were challenged with Aspergillus flavus for 15 days. Aspergillus flavus resulted in the mortality of 100% of the control group and the groups with lower doses of nanocurcumin (T1 and T2) within the first week and second week post challenge respectively. In the treatments with high doses (T3 and T4), higher survival rates were recorded in a dose‐dependent manner. The pathogenicity of Aspergillus flavus was confirmed histopathologically. It was concluded that the dietary supplementation of nanocurcumin enhanced the health status of O. niloticus by improving the haemato‐immunological response and body composition parameters of the fish, and protected it from the Aspergillus flavus infection with optimum inclusion levels of 25–40 mg/kg diet.

This research examined the role of nano curcumin (NC) on growth performances, body composition, and blood parameters of red tilapia (Oreochromis sp.) challenged with Aspergillus flavus. Fish (5.0 g ± 0.30) were randomly distributed in four equal groups (20 fish per pond in triplicates) and fed various concentrations of NC fortified with 0 (Control), 40 mg/kg (NC1), 50 mg/kg (NC2), and 60 mg/kg diet (NC3) of nano curcumin. After eight weeks of the feeding trial, the fish were challenged with A. flavus for 15 days, and the cumulative mortality was recorded. Fish fed with different concentrations of NC improved significantly (p < 0.05) the growth performances, feed utilization, and survival rate. There was no significant (p > 0.05) difference between NC2 and NC3 treatments. However, NC3 exhibited higher performances. Fish feed supplemented with NC decreased the mortality rate when challenged with A. flavus. Hence, dietary supplementation of NC enhanced the growth and health status of Oreochromis sp. and protected it from A. flavus infection. This study suggests the optimum inclusion level of NC is a 50–60 mg/kg diet.
