Microplastic (MP) pollution is a growing environmental concern, particularly in marine ecosystems. This study investigated the presence and effects of MPs common dentex (Dentex dentex), commercially ecologically important species Mediterranean Sea. Fish (n = 22) were collected from Ibiza’s coastal waters (western Mediterranean, Spain), their gastrointestinal tracts analysed to determine MP ingestion rates potential physiological impacts. detected 90.9% specimens, with an average 6.6 ± 1.2 per individual. Fibres accounted for 78.9% fragments 21.1%. Stress detoxification biomarkers assessed by categorizing fish into two groups based on load: low (<6 MPs) high (≥6 MPs). higher loads showed significantly increased antioxidant enzyme activities digestive tract, while malondialdehyde levels remained similar between groups. No significant differences observed liver biomarkers. These findings indicate that triggers responses D. dentex, activating defences tract. However, lack response suggests load not sufficient induce systemic changes. Further research needed assess long-term consequences health ecosystem sustainability.
