Abstract:
The use of nanotechnology in food production systems is being investigated globally, though there is limited research on its effect on fish nutrition. Therefore, this study aimed to identify the effects of silica nanoparticles (NPs) on the nutrition and physiology of tilapia, Oreochromis niloticus. Four isonitrogenous diets (300 g/kg crude protein) with NPs (0, 1, 2, and 3 mg/kg diet) were fed to fish (6.52 ± 0.20 g) in a recirculatory aquaculture system for 56 days. Throughout the study period, the effects of silica NP on survival rate, blood cell count, hemoglobin (Hb) level, condition factor (CF), and final product composition (except lipid content) were insignificant. However, growth performance and feed efficiency increased with an increasing level of silica NP, up to 2 mg/kg, and then decreased. This increase was due to the highest apparent protein digestibility and dry matter digestibility when fish were fed silica NP at 2 mg/kg. However, fish at the early stage showed better performance in all dietary groups than in later. Blood glucose (BG) content and histology of the kidney revealed that fish were stressed when a 3 mg/kg silica NP was used and they adapted through excessive excretion via expanded glomeruli. Though no significant effect on villi length was observed, silica NP increased the surface area widening the villi of the gut along with the number of goblet cells in the intestine significantly, when supplemented at a level of 2 mg/kg. The bioaccumulation of silica shows that incorporating silica NP in the fish feed will not compromise human health safety upon consumption. Although silica NP at 1 mg/kg and 3 mg/kg yielded some improvements to growth and final product quality, a 2 mg/kg silica NP generated the best results in all measured parameters.

Abstract:
This study was aimed to investigate the synergistic effects of selenium (Se-NP) and zinc oxide (ZnO-NP) nanoparticles on growth performance, hemato-biochemical profile, immune and oxidative stress responses, and intestinal morphometry of Nile tilapia (Oreochromis niloticus). Monosex Nile tilapia (12.50 ± 1.03 g, N= 180) were randomly allocated into 4 groups in triplicates. Fish were fed diet supplemented with 0 Se-NP and Zn-NP (control group, CG), while fish in the other experimental groups were fed diet supplemented with 1 mg/kg diet Se-NP (Se-NP group), 10 mg/kg diet ZnO-NP (Zn-NP group), and a mixture of 1 and 10 mg/kg diet Se-NP and Zn-NP, respectively (Se/Zn-NP group) for 60 days. Fish fed diet containing Se-NP, Zn-NP, and Se/Zn-NP showed higher final body weight, weight gain, weight gain rate, specific growth rate, and lower feed conversion ratio with respect to CG (P<0.05) with the highest being in fish fed with Se/Zn-NP. Fish fed with Se/Zn-NP showed higher hemoglobin, red blood cells, and globulin (P<0.05). The highest phagocytic activity, phagocytic index, lysozyme activity, and immunoglobulin M was recorded in fish that received Se/Zn-NP followed by Se-NP, Zn-NP, and the lowest in CG (P<0.05). Fish that received diet supplemented with Se-NP, Zn-NP, and Se/Zn-NP significantly (P<0.05) increased superoxide dismutase and catalase while reduced malonaldehyde activity compared to CG. Intestinal morphometry revealed significantly (P<0.05) increased villi length and goblet cells number in fish fed with Se-NP and/or Zn-NP. In conclusion, dietary supplementation of Nile tilapia with Se-NP and Zn-NP induces synergistic effects that improve growth performance, blood health, and intestinal histomorphology.

Abstract:
The field of nanotechnology has been one of the major focus of research for scientists across the world. This field deals with the production and usage of nanoscale materials. The popularity of nanotechnology is due to its unique properties that cannot be found in its large counterpart. In these recent years, zinc oxide nanoparticles (ZnO NPs) emerged as an important ceramic material that can be utilized across various fields such as medicine, cosmetics, textiles, wastewater treatment and many others. The fabrication of ZnO NPs can proceed through three major pathways which are physical, chemical and green synthesis. Among these synthesis method, green synthesis is preferable as it is more environmentally friendly. In this review, we summarize the various techniques of green synthesis in fabrication of ZnO NPs.
