“…It provides protection to the cells against oxidant materials by increasing the production of selenoenzymes and selenoproteins (GPx system, thioredoxin reductase (TrxR), selenoprotein P, etc.). Thus, an increased amount of these proteins will show a more protective role and thus enhances the immunity status of fish and other animals (Burk et al, 2003;Kumar et al, 2008), while low concentrations of selenoproteins increase oxidative stress, which then leads to viral infection (Sritunyalucksana et al, 2011). These selenoproteins participate actively in the antioxidant defense system and prevent the harmful effects of reactive oxygen species (Tapiero et al, 2003).…”

A 70-day feeding trial was conducted to evaluate the effects of dietary supplementation of selenium nanoparticles (Se-NPs) on physiological and biochemical aspects of juvenile mahseer (Tor putitora) fish. Maintaining a 40% protein level, 2 different experimental diets supplemented with 0% Se-NPs and 0.68 Se-NPs mg kg -1 were fed to triplicate groups of fish. The experiment was conducted in a semistatic condition consisting of 6 fiber tanks. The fish were first acclimatized, and then 30 fish per tank were randomly put into each fiber tank. At the end of the feeding trial, samples were collected from the fish and analyzed. Results obtained showed that the diet supplemented with Se-NPs significantly increased (P < 0.05) physiological aspects like red blood cell count, hemoglobin level, hematocrit values, and lysozyme activity as compared to the basal diet. Similarly, biochemical parameters including serum growth hormone levels, tissue total protein content, and glutathione peroxidase activity in liver and muscle tissues of T. putitora also significantly (P < 0.05) increased. Thus, dietary Se-NP supplementation at the rate of 0.68 mg kg -1 diet has very beneficial effects on the physiobiochemical health aspects of juvenile T. putitora.

“…The practical impact of improved Se status on growth and health has been illustrated in a recent work by Sritunyalucksana, Intaraprasong, Sa‐Nguanrat, Filer and Fegan (2008) with Pacific white shrimp ( Penaeus vannamei ), which demonstrated that the addition of organic selenium to the diet resulted in better growth (Fig. 6).…”

The promotion of nutritional strategies that optimize natural defence mechanisms in ¢sh is of critical importance in producing robust juveniles and adult ¢sh. These animals are more capable of minimizing the impact of opportunistic pathogen attack, thus improving liveability and performance characteristics. The importance of the piscine gastrointestinal tract as a major endocrine and osmoregulatory organ is well reported as is its function as a defensive barrier to pathogen attack. Investigations using the inclusion of a speci¢c structural form of mannan oligosaccharide have been shown to improve the performance parameters, immune status, and gut morphology and improve an important aspect of barrier protection through the enhancement of mucal production in a number of aquaculture species. The selenium status of an animal is pivotal in determining the success of the innate and adaptive immune response of the animal, and the use of an organic selenium source, in the form of a selenoyeast, has been shown to improve enzyme function and tissue uptake. The antioxidant role of many of the selenoptroteins and the role of selenium in the glutathione peroxidase enzyme pathways involved in the control of oxidative stress is critical if oxidative damage and cell membrane lipid peroxidation are to be prevented. The use of these compounds as feed additives has important implications for health management in commercial aquaculture facilities. Further research is needed to evaluate the bene¢ts o¡ered by a range of commercial products. E¡ect of diet on mucin kinetics and composition: nutrition and health implications.

“…On the other hand, in hybrid tilapia, hematocrit level dropped significantly low when selenium supplementation level decreased up to zero levels [24]. Amounts of RBCs, hematocrit, lipids, hemoglobin, glucose and protein increased when the concentration of organic selenium increased in fish feed up to 0.3g/kg clearly indicating the improvement in fish health [25] because of selenium dose. Hematological variables are affected by different protein levels, the weight of fish and related indices [26] as well as due to deficiency of micronutrients like selenium.…”
