Microplastics Ingestion by Fish in the Biawak Island

Plastic pollution is a growing global concern. The Biawak Island is region conservation area in Indramayu, so not much human activity. But, marine debris in the Biawak Island is rife. In the present study, we investigated microplastic accumulation on Fish in the Biawak Island. This study fish is divided into 3 groups based on feeding habits, that is carnivore, herbivore and omnivore. We assessed the abundance of microplastic debris found in the gastrointestinal tract of fishes caught by local fishermen. Carnivore fish grup found 49-205 microplastic particle per-individual, herbivore fish grup found 60-316 microplastic particle per-individual, and omnivore grup found 83-106 microplastic particle per-individual. The ingestion of microplastics by fish was negatively correlated with the diversity of feeding habits. But accumulated of microplastic density in herbivore and carnivore is significantly different to omnivore.
