Gut microbiota is known to influence the physiology, health, nutrient absorption, reproduction, and other metabolic activities
of aquatic organisms. Microbial composition can influence intestinal immunity and are considered as health indicators.
Information on gut microbial composition provides potential application possibilities to improve shrimp health and production.
In the absence of such information for Penaeus indicus, the present study reports the microbial community structure
associated with its early developmental stages. Bacterial community associated with the early developmental stages (egg,
nauplii, zoea, mysis, PL1, PL6 and PL12) from two hatchery cycles were analysed employing 16S rRNA high throughput
sequencing. Proteobacteria and Bacteroidetes, were the two dominant phyla in P. indicus development stages. Sequential
sampling revealed the constant change in the bacterial composition at genus level. Alteromonas was dominant in egg and
nauplii stage, whilst Ascidiaceihabitans (formerly Roseobacter) was the dominant genera in both PL6 and PL12. The bacterial
composition was highly dynamic in early stages and our study suggests that the mysis stage is the critical phase in transforming
the microbial composition and it gets stabilised by early post larval stages. This is the first report on the composition
of microbiota in early developmental stages of P. indicus. Based on these results the formation of microbial composition
seems to be influenced by feeding at early stages. The study provides valuable information to device intervention strategies
for healthy seed production.
