Although the common, silver, and bighead carps are native sparsely distributed in Eurasia, these fish have become abundant invasive North America. An understanding of biology species may provide insights into sustainable control methods. The animal-associated microbiome plays an important role host health. Characterization carp factors that affect its composition is step toward interrelationships between their environments. We compared fecal microbiomes from wild laboratory environments using Illumina sequencing bacterial 16S ribosomal RNA (rRNA). communities were diverse, with Shannon indices ranging 2.3 to 4.5. phyla Proteobacteria, Firmicutes, Fusobacteria dominated guts, comprising 76.7 % total reads. Environment played a large shaping microbial community composition, among captive fishes more similar than fishes. differences could be attributed feeding preferences, diet did not strongly structure laboratory-housed Comparison wild- lab-invasive revealed five shared OTUs comprised approximately 40 core microbiome. environment dominant factor carps. Captivity alters relative fish, while pronounced within habitats. Despite absence true stomach, exhibited microbiota warrants future study.
