Abstract: |
Balanced aquafeed is the key factor for enhancing the productivity of aquatic animals. In
this context, aquatic animals require optimal amounts of lipids, proteins, carbohydrates, vitamins,
and minerals. The original plant and animals’ ingredients in the basal diets are insufficient to provide
aquafeed with suitable amounts of minerals. Concurrently, elements should be incorporated in
aquafeed in optimal doses, which differ based on the basal diets’ species, age, size, and composition.
Selenium is one of the essential trace elements involved in various metabolic, biological, and physiological
functions. Se acts as a precursor for antioxidative enzyme synthesis leading to high total
antioxidative capacity. Further, Se can enhance the immune response and the tolerance of aquatic
animals to infectious diseases. Several metabolic mechanisms, such as thyroid hormone production,
cytokine formation, fecundity, and DNA synthesis, require sufficient Se addition. The recent progress
in the nanotechnology industry is also applied in the production of Se nanoparticles. Indeed, Se
nanoparticles are elaborated as more soluble and bioavailable than the organic and non-organic
forms. In aquaculture, multiple investigations have elaborated the role of Se nanoparticles on the performances
and wellbeing of aquatic animals. In this review, the outputs of recent studies associated
with the role of Se nanoparticles on aquatic animals’ performances were simplified and presented for
more research and development.
