Abstract

Probiotics are considered as an excellent tool for microbial management in mariculture. They play a major role in mariculture either to establish optimal microbial communities in live feed cultures or as direct feed supplementation for fish larvae. In the long run, adding probiotics to the raising water of live meals may benefit the larvae in addition to enhancing their quality andquantity. Bioencapsulation of various live feeds, including copepods, rotifers, and Artemia, improves the nutritional status and general health of fish. Enrichment of live feed with probiotics has been applied for many years as microbial adjuncts with promising effects on the growth, health and culture environment of aquatic organisms (FAO & WHO, 2002), that resulted in a growing interest in learning about the advantages of probiotics in live feed cultures. Much attention has been devoted to manipulate the composition of the microbial community in order to improve the stability of cultures and mitigate the proliferation of harmful bacteria. Application of probiotics in live feed cultures enhance the density, swimming behaviour and feeding performance of phyto and zooplankton which will be used as feed for fish and shrimp larvae. Aquaculture faces a significant challenge with regard to organic enrichment and nitrogenous wastes which encompass ammonium (NH3 +) and ammonia (NH3) . The present chapter deals with the role of probiotics in mass culture of marine microalgae, rotifers and copepods.
