Abstract

Probiotics in the fish’s body are able to optimize the nutrition of feed given for growth. Microcapsule techniques can protect probiotics as they pass through the digestive tract. This study aims to study the increase in growth of tiger grouper fish fed with probiotic Bacillus sp. Microcapsules. D2.2 with different dosages. The study wasconductedinMay-June(30days) with 5 treatments and 3 replications. ThetreatmentsappliedareK-(feedwithout probiotics), K + (feed + liquid probiotics), A (feed + probiotic microcapsules 1 gram / kg of feed), B (feed + probiotic microcapsules 2 gram / kg of feed), C (feed + probiotic microcapsules 3 grams / kg of feed). The following are the highest observations, namely absolute weight gain (23.8 ± 0.7) grams, specific growth rate (1.35 ±0.04)%/day,feedcovertionratio(FCR) (1.3±0.1)),survivalrate(83±2.9)% and protein digestibility 90.56% while the lowest value is in the control treatment.The results showed that the administration of probiotic microcapsules was able to significantly increase the growth of tiger grouperfish compared to control treatments. Keywords Bacillus sp D2.2, viability, digestibility
