Abstract

AbstractMinerals are essential nutrients that play a key role in all living organisms. Minerals act as a catalyst for many biological functions of organisms including skeletal formation, maintenance of colloidal systems, acid-base equilibrium, and other biologically important compounds like enzymes, hormones, vitamins, etc. Aquatic animals can obtain essential minerals from diet and water. However, the quantitative requirement of each dietary mineral is species dependent. The quantitative requirement of dietary minerals has attained significant improvements in the aquaculture industry, particularly in fish and crustaceans. The adequate level of essential dietary minerals like calcium, potassium, sodium, iron, zinc, copper, selenium, etc., can promote survival, growth, proximate composition, nonspecific immunity, and disease resistance against the pathogen in fish and crustaceans. Regarding this, the optimum dietary requirement of minerals in fish and crustaceans has been studied and reported by earlier researchers. This chapter deals on the role of 11 dietary minerals such as calcium, magnesium, potassium, phosphorus, sodium, copper, chromium, fluorine, iron, selenium, and zinc) on survival, growth, feed index, digestive enzymes, proximate composition, immune response, antioxidants and disease resistance of fish and crustaceans.KeywordsMineralsSurvivalGrowthFishCrustaceansImmunityDisease resistance
