Summary

Wild red mullet caught near Mallorca were found to have ingested microplastics in 28% of sampled fish, and those fish showed activation of liver detoxification systems compared to fish without plastic in their stomachs. This is among the first evidence that wild fish experience physiological responses to microplastic ingestion, though no oxidative damage was detected.

Marine litter greatly affects marine species and ecosystems (1), however there is little evidence of physiological responses of vertebrates to plastic exposure. In this study, wild mullets Mullus surmuletus were obtained from fishing vessels operating in Mallorca Island (W Mediterranean). Stomach content analyses and identification under microscope determined that 28% of the samples had ingested microplastics. Liver samples of surmullets with and without microplastic ingestion were analysed to determine physiological effects. Results suggest an induction of the detoxification system in M. surmuletus Linnaeus, 1758 but no oxidative stress or cellular damage
