Résumé
Microplastics are ubiquitous throughout the oceans, yet few studies have documented their occurrence in marineorganisms associated with coral reefs. Four genera of adult fish were sampled (Myripristis spp., Siganus spp.,Epinephelus merra and Cheilopogon simus) from different trophic guilds around the tropical island of Moorea,French Polynesia. Digestive tracts from 133 adult fish were surveyed and microplastics were found in 28 tracts(21%). Abundance of ingested microplastic pieces per individual fish varied from 1 to 3 pieces, with an averageof 1.25 ± 0.13 ingested microplastic pieces. Microplastics size ranged from 0.031 to 2.44 mm and 70% ofmicroplastics did not exceed 0.3 mm in size. Overall, this study shows that the number and size of microplasticingested per trophic groups are independent of trophic guild. Additional studies are needed to sample in othertropical regions in order to have a better assessment of microplastic occurrence in coral reef
