Microplastic abundance in anchovy Stolephorus indicus (Van Hasselt, 1823) in the Lada Bay, Pandeglang, Banten
AI summary Read the abstract
Researchers found high concentrations of microplastics averaging 246 particles per individual in anchovies from Lada Bay, Indonesia, along with 156 particles per litre in the surrounding water. Fibres dominated both matrices, indicating that synthetic textiles are a major local source of contamination.
Abstract Currently, microplastic is one of the serious threats to the marine environment. This research aims to investigate the abundance and types of microplastics contained in anchovies Stolephorus indicus and water from Teluk Lada (Lada Bay), Tanjung Lesung, Pandeglang, Banten. Anchovy samples were extracted with 1M NaOH and 5 % sodium dodecyl sulphate (SDS). Meanwhile, water samples were treated by mixing it into NaCl concentrate solution. The results show that 246.10 ± 32.25 ind −1 and 156 ± 13.46 L −1 microplastic particles were found in the anchovies and water, respectively. In addition, 216.30 ± 30.13 ind −1 microplastics were found in the anchovies taken from traditional market as a control. The types of microplastics found in anchovies were fibers (77.41 %), films (16.64 %), fragments (5.6 %) and a little amount of granules (0.35 %). Meanwhile, the water samples were contained with fibers (81.03 %), films (11.92 %), fragments (7.0 %) and a little amount of granules (0.05 %). Our study found that fibers were the dominant pollutant in all samples and the amount of microplastics contained in water is strongly related to the amount of microplastics found in anchovies.

Researchers investigated microplastic contamination in the digestive tracts of anchovies (Stolephorus spp.) from East Lombok Harbour, Indonesia, finding an average of 88 microplastic particles per individual. Fibres (51%) and films (30%) dominated the microplastic morphologies, with FTIR spectroscopy confirming polymers including polypropylene, polystyrene, and polyethylene.

Microplastic contamination was found in anchovies sampled from 14 locations across Indonesia, with contamination levels varying by location and suggesting that the widespread marine distribution of microplastics poses risks to commercially important small pelagic fish.
Microplastic exposure in anchovies: baseline evidence from small-island waters of Indonesia
AI summary Read the abstract
Researchers checked anchovies from a small Indonesian island for microplastics and found tiny plastic bits, mostly fibers, in almost all the fish, averaging about one particle per anchovy. Since anchovies are typically eaten whole, this means people consuming them may also be swallowing these plastic particles, though this study only measured contamination levels and didn't test health effects. The findings highlight the need for ongoing monitoring and stronger efforts to reduce plastic pollution in our oceans to protect seafood safety.

Ingestion of microplastics by anchovies from Talisayan harbor, East Kalimantan, Indonesia
AI summary Read the abstract
Researchers examined microplastics in the digestive tracts of anchovies (Stolephorus spp.) from Talisayan harbor, East Kalimantan, finding an average of 366 particles per individual, with microfilm (50%) and microfiber (30%) as dominant shapes and polypropylene, high-density polyethylene, and foamed polystyrene as the main polymers. The study also detected mercury contamination in the same specimens, raising concerns about combined contaminant burdens in this commercially harvested fish.
