Data on community structure and diversity of the intestinal bacteria in elver and fingerling stages of wild Indonesian shortfin eel (Anguilla bicolor bicolor)

This article describes the data on community structure and diversity of intestinal bacteria of Indonesian shortfin wild eel fingerling and elver (Anguilla bicolor bicolor). The specimens were obtained from Ci Kangean River, Alur Village, Cipatujah District, Tasikmalaya, West Java, Indonesia. The data were generated using DNA metagenomic approach on an Illumina paired-end platform by utilizing the V3–V4 region of the 16S rRNA gene. A total of 151,636 reads with 91.60% effective tags and 155,388 with 84.86% effective tags were generated from the intestine of wild eel fingerling (WF) and elver (WE), respectively. The total OTUs was 100 in WF and 358 in WE. The phyla Bacteroidetes (50%), Firmicutes (15%), Proteobacteria (13%), Fusobacteria (11%) and Verrucomicrobia (8%) were found in WF, and Proteobacteria (64%), Firmicutes (34%) and Fusobacteria (1%) were found in WE. The predominating families in WF were Porphyromonadaceae (50%), Clostridiaceae (12%), Fusobacteriaceae (10%), Verrucomicrobiaceae (8%), and in WE were Enterobacteriaceae (38%), Clostridiaceae (30%), Aeromonadaceae (17%), Moraxellaceae (7%). The predominating genera in WF were unassigned (48%), Cetobacterium (10%), Clostridium (sensu stricto) (9%), Akkermansia (8%), Odoribacter (4%), Bacteroides (4%), Desulfovibrio (4%), and in WE were Plesiomonas (36%), Clostridium (sensu stricto 1) (31%), Aeromonas (17%), Acinetobacter (7%). The amount of lactic acid bacteria found in the intestine of WF was 0.0028% and WE was 0.1218%. The data provide baseline information on the changes in the community and bacterial composition in line with the stages of growth and development of wild Indonesian shortfin eels.
