Live food organisms are commonly regarded as “living capsules of nutrition”, rich in proteins, vitamins, carbohydrates, minerals, amino acids, and fatty acids. Live food such as zooplankton is capable of producing appetite-stimulating effects on larvae and is able to swim freely in the water column, thereby being constantly accessible to finfish and crustacean larvae. Even though the use of live food in larval rearing has been reported to improve larval growth performance, survival, and disease resistance, the cultivation and management of live food for aquatic production are costly and unpredictable. Although, live food organisms are superior in terms of acceptance, rotifers and Artemia are evidently lacking in crucial nutrient constituents. Hence, through various techniques of nutrient enrichment, live food with a nutritional profile that meets the requirements of fish and crustacean larvae can be mass produced. Therefore, the enrichment of zooplankton live food through bioencapsulation are highly recommended as it is convenient to further improve the nutritional status of live food for consumption by fish larvae. Consequently, the encapsulation of nutrient-deficient live food such as rotifers and Artemia with micro- and macro-nutrients has been demonstrated to enhance the performance of fish larvae, thus enabling maximisation of production and profit.
