Live Feed Enrichment – A Possible Step Towards a Sustainable Blue Revolution

Abstract

Enrichment is the process of increasing the quality or nutritional value of any substances, i.e., live feeds. The live feeds are essential for larval rearing of commercially critical aquatic organisms. Still, the significant constraint noticed in the live feed sector is that sometimes they lack vital nutrients such as EPA, DHA, etc. Enrichment with crucial nutrients can improve larval survivability during early larval stages, which is the major bottleneck observed during larvi culture techniques in aqua hatcheries. Simultaneously various live feed such as Rotifers, Cyclops, copepod, Cladocerans, and Artemia are widely used as a carrier for bio encapsulation process in aquaculture. Numerous substances, especially essential amino acids, fatty acids, attractants, vitamin-mineral premix, are widely used for bio encapsulation in live feed culture units. Live feed brings those substances into their body either by feeding or osmoregulation. The main idea behind this article is to demonstrate the proper encapsulation method for various live feeds in aqua hatcheries.
