Assessing the Educational Significance of Microplastic Impact on Sardinella gibbosa: Implications for Marine Sustainability and Public Health in Caraga Region, Philippines

Abstract

This study aimed to examine and document the presence of microplastics in the gut contents of fish species collected from the coastal area of Magallanes, Agusan del Norte. A total of sixty fish samples were analyzed, with forty-five of them showing evidence of microplastic ingestion. The majority of the microplastics identified were fibers, which accounted for over 90% of the samples observed. These fibers are most likely sourced from discarded fishing nets, weathered plastic debris, and other forms of environmental pollution. The findings clearly indicate that microplastics are present in the gut contents of the fish from this region, suggesting a significant contamination of local marine life. However, it is important to note that this study was focused solely on identifying the presence of microplastics in the fish’s digestive system, and did not examine the potential health impacts on the fish or humans consuming them. The ingestion of microplastics by marine organisms is a growing concern due to its potential to affect both aquatic species and human health through the food chain. As such, further research is recommended to investigate the long-term effects of microplastic contamination, particularly its impact on fish health and the possible risks posed to humans who consume contaminated seafood. Additionally, continued monitoring and efforts to reduce plastic pollution in marine environments are critical to mitigating the harmful effects of microplastics on marine life and human populations.
