16S rRNA amplicon sequences of total microbiota and intestinal microbiota from Caligus rogercresseyi

Sea lice (Caligus rogercresseyi) pose a significant sanitary threat to salmon aquaculture in Chile, yet their associated microbiota remains poorly understood. We used full‑length 16S rRNA amplicon sequencing and functional prediction to compare the total and intestinal microbiota of adult male and female sea lice.
