Dietary Effects of Nano Curcumin on Growth Performances, Body Composition, Blood Parameters and Histopathological Alternation in Red Tilapia (Oreochromis sp.) Challenged with Aspergillus flavus

Abstract

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.

The effects of dietary Spirulina platensis or curcumin nanoparticles on performance, body chemical composition, blood biochemical, digestive enzyme, antioxidant and immune activities of Oreochromis niloticus fingerlings

“…The current study results indicated that Nile tilapia given diets with CUR-NPs or SP for nearly two months displayed significant enhancement in growth and feed efficiency (FCR, and SGR) indices. Similar enhancements in growth variables were observed in Nile tilapia ( Oreochromis niloticus ) [ 1 , 79 , 80 ], Red tilapia [ 6 ], European seabass ( Dicentrarchus labrax ) [ 81 ], white-leg shrimp ( Litopenaeus vannamei ) [ 82 ] given diets containing CUR-NPs, as well as in gilthead seabream ( Sparus aurata ), rainbow trout ( Oncorhynchus mykiss ), common carp ( Cyprinus carpio ) and grass carp ( Ctenopharyngodon Idella )fed CUR-based diets [ 83 – 86 ]. The growth-promoting impact of curcumin might be attributed to its ability to enhance digestive enzyme activity in the hepatopancreas and intestine, producing an improvement in nutrient absorption and utilization [ 87 , 88 ].…”

“…In Africa, both in its native habitat and farmed areas, it is typically the most valuable fish species captured from both inland fisheries and aquaculture mass production [2][3][4]. Especially in developing countries, Oreochromis niloticus is ideal for intensive or extensive aquaculture systems, due to its rapid growth, tolerance of a wide range of ecological conditions, resistance to diseases and stress, ability to reproduce under captive conditions, short generation time, low-trophic feeding, and acceptance of artificial feeds [5,6]. Intensive tilapia farming encourages disease outbreaks [7].…”

Effects of Bacillus subtilis as a single strain probiotic on growth, disease resistance and immune response of striped catfish (Pangasius hypophthalmus)

“…Multiple studies substantiate the probiotic effects of B . subtilis , including the prevention of gastrointestinal disorders, leading to the improvement of pond water quality and the increased survival rate of animals in aquaculture [ 17 , 36 ]. A study conducted by [ 37 ] examined the synergistic effects of Bacillus strains on the growth and immune response of striped catfish.…”

“…However, among all other probiotics, Bacillus subtilis is widely accepted in aquaculture due to its spore-forming ability [32], production of a broad spectrum of antibacterial substances [33], and the presence of high-antioxidant-activity substances such as superoxide dismutase (SOD) and glutathione (GSH) [34,35]. Multiple studies substantiate the probiotic effects of B. subtilis, including the prevention of gastrointestinal disorders, leading to the improvement of pond water quality and the increased survival rate of animals in aquaculture [17,36]. A study conducted by [37] examined the synergistic effects of Bacillus strains on the growth and immune response of striped catfish.…”

Impacts of Dietary Selenium Nanoparticles from Spirulina platensis on Growth Performance, Physio-Biochemical Components and Alleviating Effect against Cadmium Toxicity in Pacific White Shrimp Litopenaeus vannamei

“…Using nanoparticles in fish feed formulations has recently gained considerable attention because it offers unique methods for increasing bioavailability, safety, and absorption in aquaculture [9]. The addition of Se nanoparticles to the diet improves the feed efficiency and growth performance of many aquatic species, including Clarias gariepinus [10] and Oreochromis niloticus [11]. Moreover, dietary selenium enhances immunity and resistance against oxidative stress in rainbow trout [12], Dicentrarchus labrax, and Penaeus vannamei [13].…”
