The Comparative Analysis of Microplastic Contamination in Kembung (Rastrelliger sp) and Kurisi Fish (Nemipterus nemurus) from Coastal Waters of Mangindara, Indonesia
AI summary Read the abstract
Researchers found tiny plastic fragments called microplastics in every single fish sample they tested from a polluted coastal village in Indonesia, with kurisi fish containing even more plastic bits than kembung fish. Since these fish are regularly caught and eaten by local communities, this means people may be unknowingly consuming plastic particles along with their seafood, highlighting why cutting back on single-use plastics and improving waste management matters for both ocean health and what ends up on our plates.
Background: Microplastics are a major component of marine debris, andtheir accumulation in aquatic environments can disrupt marine food chains,particularly in fish. Mangindara Village, South Galesong District, TakalarRegency, is a coastal area currently experiencing severe environmentalpollution, especially from plastic waste and household effluents. This condition raises serious concern, as plastic debris can degrade into microplastics that are not visible to the naked eye, enter marine organisms such as fish, and ultimately pose risks to human health. Methods: This study employed an observational design with a descriptive approach and laboratory analysis to examine the presence, types, and abundance of microplastics in Fish kembung (Rastrelliger sp.) and kurisi (Nemipterus nemurus) collected from the waters of Mangindara Village. The study population consisted of fish kembung and kurisi fish captured in the study area. Samples were selected using random sampling, with three individuals from each species analyzed. Results: The results showed that all examined fish samples contained microplastics. The average microplastic concentration in fish kembung was 0.061 g, whereas kurisi fish exhibited a higher average concentration of 0.085 g. The identified microplastics were predominantly line-shaped and appeared in blue, black, and red colors. Conclusion: These findings indicate widespread microplastic contamination in coastal fish species consumed by local communities. Therefore, reducing single-use plastic use and improving proper waste management practices are strongly recommended.

Researchers measured microplastic contamination in two fish species consumed by coastal communities in South Sulawesi, Indonesia, and estimated human microplastic intake through fish consumption. The findings suggest that local fish consumption is a meaningful exposure pathway for microplastics in this community.
Identification and analysis of microplastic abundance in the digestive tract of Baung fish (Mystus nemurus Valencionnes, 1840) in the waters of the Musi River, Palembang City
AI summary Read the abstract
Scientists studying Indonesia's Musi River found microplastic particles—tiny plastic bits mostly from broken-down plastic bags and packaging—in the digestive tracts of every single Baung fish they tested (30 out of 30). Since this fish is commonly eaten by local communities, the findings suggest that when people catch and eat fish from polluted waterways, they may also be consuming these plastic particles, raising concerns about long-term health effects that scientists are still working to understand.
Assessment of Microplastic Pollution in Fresh Fish and Pindang Fish and its Potential Health Hazards in Coastal Communities of Banyuwangi Regency, Indonesia
AI summary Read the abstract
Researchers analyzed microplastic contamination in fresh and processed pindang fish from the coastal community of Muncar, Banyuwangi, Indonesia, and surveyed local consumption habits. They found microplastics present in fish samples and used statistical analysis to explore potential correlations with health outcomes reported by local residents. The study highlights concerns about dietary microplastic exposure in communities that depend heavily on seafood.
The presence of microplastics in the digestive tract of commercial fishes off Pantai Indah Kapuk coast, Jakarta, Indonesia
AI summary Read the abstract
Commercial fish from nine species collected at the Pantai Indah Kapuk coast in Jakarta were dissected for microplastics, with 97.13% of 174 fish containing an average of ~12 particles per individual dominated by fibers and fragments of PE, PP, and PS. The study documents near-universal microplastic contamination in urban coastal fisheries in Indonesia with implications for seafood consumers.
Influence of fish length and weight on microplastic accumulation in freshwater fish from the Kahayan river, Indonesia
AI summary Read the abstract
Scientists found tiny plastic bits (mostly plastic fibers) inside most fish—65%—caught in an Indonesian river, with bigger fish tending to carry larger plastic fragments. This matters because these fish are eaten by local communities, meaning microplastics could be making their way into people's diets, though more research is needed to know exactly how much and how risky this is for our health.
