Anguilla japonica, A. marmorata and A. bicolor pacifica are important eel species for aquaculture in Taiwan. In the past, seldom studies focused on the intestinal microbiome of them or the probiotics used in their cultivation. Probiotics are microbes that can improve the health of organisms, and the microbes isolated from the intestines of organisms might be the potential probiotics. Therefore, the aim of this study was to collect the intestinal mucus samples of these three eel species for investigating the autochthonous microbiome using 16S rDNA sequencing. The diversity, abundance of the intestinal microbiome and compositions of all the libraries were identified. Moreover, the composition of intestinal microbiome of eel was suggested that it would be affected by the waters and the characteristics of different eel species. Furthermore, most of the identified predominant genera of the intestinal microbiome of these three eel species, such as Cetobacterium, Clostridium, Shewanella, Acinetobacter and Bacteroides, seemed to have great potential as the probiotics. In the future, more studies shall be conducted to promote the practical application of these candidate probiotics for improving the techniques of eel farming.
