Dietary supplementation with nerolidol nanospheres improves growth, antioxidant status and fillet fatty acid profiles in Nile tilapia: Benefits of nanotechnology for fish health and meat quality

Diphenyl diselenide‐loaded nanocapsules in silver catfish feed enhance growth, improve muscle antioxidant/oxidant status and increase selenium deposition: Advantages of nanotechnology for fish health

“…The most important finding of the present study is that the antioxidant defence system, as measured by SOD and CAT activities, was upregulated only in fish supplemented with Ph 2 Se 2 ‐loaded in nanocapsules, explaining the reduction in lipid peroxidation and H 2 O 2 content. Dietary supplementation with 3 mg Ph 2 Se 2 /kg enhanced muscle CAT activity, suggesting a better capacity to remove H 2 O 2 , reduction in muscle H 2 O 2 levels in the same group, in agreement to findings reported by Baldissera, Souza, Zeppenfeld, et al (2020) in the muscle of Nile tilapia fed nerolidol‐loaded nanocapsules. Similarly, Neamat‐Allah et al.…”

“…Positive effects compared with free form are associated with a reduction of particle size, more sustained release of the active compound, improved bioavailability and higher levels of molecular dispersion (Luis et al., 2019). In particular interest for the present study, Baldissera, Souza, Zeppenfeld, et al (2020) demonstrated that Nile tilapia ( Oreochromis niloticus), fed with nerolidol‐loaded in nanospheres, showed an increased final weight compared with a control group, a condition not observed in fish fed with free nerolidol. The authors concluded that nanoscience could be exploited to enhance fish performance.…”

“…(2018) observed that iridescent sharks ( Pangasinodon hypophthalmus ) fed for 60 days with feed containing 1 mg Se nanoparticles/kg presented increases in weight gain and SGR, neither of which was observed using free Se. Similarly, Baldissera, Souza, Zeppenfeld, et al (2020) found that Nile tilapia fed 60‐days with 1.0 ml nerolidol‐loaded nanospheres presented significant increases in final mean weight and average daily weight gain compared with Nile tilapia fed with basal and free nerolidol‐supplemented diets. To enhance Nile tilapia growth performance, Neamat‐Allah et al.…”

“…The diameter, polydispersity and zeta potential of the nanoparticles were measured using dynamic light scattering on a Zetasizer ® NanoZS (Malvern), while pH was evaluated using a potentiometer (Digimed ® ), following the methodologies described in detail by Baldissera, Souza, Zeppenfeld, et al (2020). The quantification of Ph 2 Se 2 in the nanocapsules was performed using high‐performance liquid chromatography (HPLC) following the method described by Giordani et al.…”

“…Nanotechnology refers to the design, synthesis, characterization and application of materials that possess functional organization on the nanometric scale (Silva, 2010); reduction of particle size augments reactivity and alters the pharmacodynamics and pharmacokinetic properties of active ingredients (Jiang, Chekuri, Fang, & Zhang, 2019). Recently, nanotechnology has become a potential approach for production, processing, storage, transportation, traceability, safety and security of aquaculture foods (Dar, Rashid, Majid, Hussain, & Dar, 2019), as well as for improving fish performance (Baldissera, Souza, Zeppenfeld, et al, 2020). According to Khan, Saeed, and Khan (2019), nanoparticles can be divided into various categories linked to morphology, size, and chemical properties.…”
