ABSTRACT
Seawater acidification and warming have been found to affect the early life of many marine organisms, but their effects on microbial community in environment related development stage aquaculture species rarely investigated. To understand how seawater impact systems, we designed four microcosms monitor characterize composition corrugated plates Apostichopus japonicus culture tanks during its post-settlement stage. High-throughput 16S rRNA sequencing revealed that bacterial varied significantly different periods incubation. The diversity were obviously changed by period then tended revert level control group. Acidification increased relative abundance dominant families Rhodobacteraceae Flavobacteriaceae period, suggesting microbiota could increase predominant taxa adapt CO 2 concentration reconstruct a stable structure. No interaction effect both factors was observed combined Results reveal communities A. tank affected incubation, acclimatize temperature. This study provides new insights into variation adaptation responses systems warming.
