Efficacy of dietary Nano-selenium on growth, immune response, antioxidant, transcriptomic profile and resistance of Nile tilapia, Oreochromis niloticus against Streptococcus iniae infection

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

“…Similarly, Neamat‐Allah et al. (2019) observed a significant increase in the serum antioxidant defence system of Nile tilapia fed with sodium‐selenite nanocapsules through the augmentation of SOD and catalase activities, as well as via the reduction of lipid damage when compared to fish fed with free sodium‐selenite, concluding that nanotechnology is a tool to enhance Se antioxidant capacity. Moreover, Naderi, Keyvanshokooh, Ghaedi, and Salati (2019) demonstrated that rainbow trout ( Oncorhynchus mykiss ) fed with a diet containing 1.02 mg Se‐loaded nanocapsules/kg diet for 60 days presented a significant reduction muscle lipid damage, as well as a significant improvement on antioxidant defence system via an increase in muscle CAT activity, this being a compelling alternative to improve fish health status.…”

“…To enhance Nile tilapia growth performance, Neamat‐Allah et al. (2019) developed sodium‐selenite nanocapsules and observed a significant increase in final weight, body weight and SGR in Nile tilapia fed with sodium‐selenite nanocapsules compared with basal and free sodium‐selenite diets, concluding that nanoencapsulation in this inorganic form of Se was a compelling alternative to improve Nile tilapia growth. The mechanism of action related to enhancement on fish growth using nanotechnology remains unknown; nevertheless, the effect may be attributable to the reduction of particle size, sustained release of the active compound, improved bioavailability and high levels of molecular dispersion (Luis et al., 2019).…”

“…The authors concluded that nanoscience could be exploited to enhance fish performance. Moreover, a study conducted by Neamat‐Allah, Mahmou, and El Hakim (2019) revealed that Nile tilapia fed with sodium‐selenite nanocapsules showed an increased final weight, body weight and specific growth rate compared with fish fed with basal diet, a condition not observed in fish fed with free sodium‐selenite, concluding that nanoscience can be an alternative to improve fish performance and antioxidant status. Although the application of nanotechnology is at a very early stage in aquaculture, it may have the potential to solve most of the aforementioned problems via generating technical innovations at various levels (Thangapandiyan & Monika, 2019).…”

Selenium-Cultured Potamogeton maackianus in the Diet Can Alleviate Oxidative Stress and Immune Suppression in Chinese Mitten Crab (Eriocheir sinensis) Under Copper Exposure

“…It participates in regulating various physiological processes and exerts various biological functions in the form of selenoproteins (Lu et al, 2012;Nugroho and Fotedar, 2013). As the biological activity of Se and its mechanism of absorption and metabolism in the body are becoming better understood, the use of Se as a dietary supplement for aquatic animals is becoming more common (Schrauzer, 2003;Neamat-Allaha et al, 2019). The glutathione peroxidase (GSH-Px) family is an important group of selenoproteins.…”

“…Se can be supplied in the diet in three forms: inorganic (e.g., sodium selenite) (Kouba et al, 2014), organic (e.g., Se-yeast and Se-methionine) (Thomas and Janz, 2011;Wang et al, 2019), and nano-Se (Neamat-Allaha et al, 2019). Inorganic Se has low utilization, high toxicity, and environmental risks, because its residue can pollute the environment (Kouba et al, 2014).…”
