Identification of Microplastics in Three Fish Species in Tondano Lake, Minahasa, Indonesia
Summary
Researchers examined microplastic presence in the gills and gastrointestinal tracts of three fish species from Tondano Lake, North Sulawesi (mujair, payangka baru, payangka lama), finding contamination in all species with mujair showing the highest abundance and fibers being the most prevalent type.
Microplastic pollution is a significant threat to aquatic ecosystems and human health, particularly in Indonesia, a major contributor to plastic waste. This study investigated the presence and characteristics of microplastics in three commonly consumed fish species from Tondano Lake, North Sulawesi: mujair (Oreochromis mossambicus), payangka baru (Oxyeleotris marmorata), and payangka lama (Ophiocara poropechala). Analysis of gills and gastrointestinal tracts (GIT) from 11 fish samples revealed microplastic contamination in all species. Mujair exhibited the highest microplastic abundance, predominantly fragments in both gills and GIT. Payangka baru showed more fibers in the GIT and fragments in the gills, while payangka lama had more fibers in the GIT and fragments in the gills. A positive correlation was observed between fish body weight and microplastic accumulation in the GIT, but not the gills. The findings confirm microplastic contamination in Tondano Lake fish, highlighting the need for stricter waste management and further research on human health implications.

Identifikasi Cemaran Mikroplastik pada Ikan Nila (Oreochromis niloticus) dan Ikan Puyau (Osteochilus vittatus) di Perairan Waduk Benanga, Samarinda
Researchers examined tilapia and puyau fish from the Benanga Reservoir in Samarinda, Indonesia, and found microplastic contamination in all 12 fish samples. A total of 155 microplastic particles were detected across the gills and digestive tracts, with fiber-type particles dominating in both species. The study highlights that plastic waste mismanagement around the reservoir is leading to microplastic accumulation in locally consumed fish.
