A review on the impact of seaweed polysaccharide on the growth of probiotic bacteria and its application in aquaculture

Abstract

The purpose of this review is to elucidate the probiotic and polysaccharide of seaweeds as a dietary supplement for promoting growth and disease resistance in aquatic animals. Because of numerous benefits, the role of dietary supplementation of seaweed polysaccharide and probiotics in promoting growth and interest in commercially important aquatic animals like prawn and fish has generated considerable interest in recent times. Control of bacterial and viral disease and enhancing the immunity of aquatic animals have become urgent needs in aquaculture production. In order to improve the production, several alternative strategies have been raised using probiotics, seaweed polysaccharide (prebiotic), and plant products as biological control agents. Furthermore, the use of natural substances in feed of aquatic animals increases consumer confidence in farmed aquatic animals. Modulation of the intestinal microflora through diet can either be accomplished by means of oral administration of prebiotic compounds or probiotic microorganisms. In some studies for growth enhancement and improvement of immunological parameters, a combination of probiotics and plant products has been reported. The present review suggests the use seaweed polysaccharide and probiotics in combination as dietary supplements due to its beneficial effects to improve the production of healthy aquatic animals.
