The parrotfishesScarus ovifronsandCalotomus japonicusinhabit the warm temperate reefs of Japan. Of the two, onlyS. ovifronscauses severe food poisoning, and the toxin that causes the food poisoning is believed to accumulate through the food chain. However, the difference in prey organisms between the two parrotfishes is not well understood. Therefore, in this study, we conducted metabarcoding analysis (18S rDNA for eukaryotes and 16S rDNA for cyanobacteria) of the gut contents ofS. ovifronsandC. japonicusto clarify those food resources. Macroorganisms (> 1 mm) in the gut contents of the two parrotfishes were mainly composed of Rhodophyta, Ochrophyta, and Cnidaria sequences, and microorganisms (< 1 mm) were mainly composed of Dinoflagellata, Arthropoda, and Chlorophyta. In addition, cyanobacteria were detected in both fishes. The gut contents ofS. ovifronscontained a high proportion of Rhodophyta sequences, whereas those ofC. japonicuscontained a high proportion of Ochrophyta sequences, and some organism sequences such as Gigartinales (Rhodophyta), dinoflagellates, and cyanobacteria were detected in onlyS. ovifrons. Our study clarified similarities and differences in the gut content composition betweenS. ovifronsandC. japonicus, providing fundamental information for elucidating the causative organism of poisoning byS. ovifrons.
