The influences of probiotics Sanolife MIC comparing with antibioticsOTC were tested in both water quality and growth parameters for the brood-stockdevelopment, incubation and hatching of Macrobrachium rosenbergii. The study was tofind out a sustainable practice of hatchery management applying probiotics instead ofusing antibiotics frequently. Influences of the application of three doses, Sanolife MIC@0.50, 0.65 and 0.80 ppm in water were checked in egg incubation, spawning andhatching phases. Sanolife Pro-1 @4 ppm was used in the feed of brood-stock as asupporting gut-probiotic in all the three trials with MIC. Findings of MIC based trialswere compared with a control group of treatments with antibiotic OTC (@4.0 ppm infavor of the objectives of the study. Among three doses as 0.50, 0.65 and 0.80 ppm ofMIC, the dose 0.65 ppm was found to be best in respect to the findings of the study.Water pH, DO, NH3, NO3 and NO2 level were found to be comparatively more stable andmore favorable in probiotics based trials than that of antibiotic. Increased feeding appetiteof spawners, earlier (4 days) embryonic development, higher (9%) hatching rate, 3% lessdisability of new hatchlings, better physical condition and higher (10%) rate of attractionto illumination of new hatchlings and absence of disease contamination in probiotic basedtrial (trial with 0.65 ppm) revealed much better efficiency and sustainability of usingprobiotics than that of antibiotic in rearing phases of berried prawn brood-stocks.Journal
