Enhancement of growth potential in freshwater prawn Macrobrachium rosenbergii with usage of water and feed probiotics in the culture operation


Author(s): SV Nagendra Prasad and M Srinivasulu Reddy

Abstract: In the present investigation, an attempt was made to probe in to the usage of both water and feed probiotics individually and in combination to monitor the growth patterns of freshwater Male and Female prawns Macrobrachium rosenbergii. The feed conversion ratio, Protein efficiency ratio and Percent survival rates were considerably increased in the culture operation, where water and feed probiotics were broadcasted. Gut microbial load was decreased and Lactobacillus count were significantly increased suggesting that both feed and water probiotics are capable of eliminating the pathogens, thereby promoting growth potentials in prawns. The Anti-oxidant enzyme activities such as SOD, Catalase and GPX were also significantly increased suggesting the elimination of ROS in the prawn species, thereby promoting growth potentials significantly. The results obtained in the present investigation aims to help for the development of adequate technology for the evaluation of the efficiency of microbial agents as Probiotics in Aquaculture in order to improve survival rate and growth to enhance yield and to minimize production cost.
