Differential Presence of Microplastics and Mesoplastics in Coral Reef and Mangrove Fishes in Isla Grande, Colombia
AI summary Read the abstract
Researchers found that fish from mangrove ecosystems in the Colombian Caribbean contained higher levels of microplastics and mesoplastics than fish from coral reef environments, suggesting that habitat type significantly influences plastic ingestion rates in marine fish species.
This study aims to determine whether differences exist between the presence of microplastics and mesoplastics in fishes of coral reef and mangrove ecosystems, in Isla Grande, Colombian Caribbean. The collection of three species of coral reef (Centropomus undecimalis, Caranx hippos, and Lutjanus synagris) and three species of mangrove from coral reef (Centropomus undecimalis, Eugerres plumieri, and Archosargus rhomboidalis) were found to have ingested microplastics and mesoplastics, with a significantly higher in the mangrove species than in the coral reef species (1.9 vs. 1.6 items/individual). Furthermore, the average abundance and weight of microplastics and mesoplastics were significantly higher in females than in males (p < 0.05) and the abundance of microplastics and mesoplastics in the intestines was significantly higher than in the stomach (p < 0.05). PE, polyester, PVC, and PET were the most abundant polymers among common plastics found in species of the two habitats. Our findings highlight the importance of more rigorous plastic waste management strategies in areas nearby the coast and mangrove habitats.

Scientists examined the digestive tracts of fish from mangrove ecosystems in Cispata, Colombian Caribbean, finding microplastics in multiple species and suggesting that mangrove habitats concentrate microplastic pollution in ways that expose fish inhabiting these nursery areas.
Widespread microplastic ingestion in Colombian Caribbean marine fish: Trophic influence, spatial-temporal trends, and polymer composition
AI summary Read the abstract
Researchers examined three commercially important fish species from the Colombian Caribbean and found microplastics in over 82% of individuals across both continental and island waters. Fiber and fragment shapes were the most common types, with higher concentrations found in coastal areas and during the wet season. The findings suggest that microplastic ingestion is widespread among Caribbean fish, with potential implications for seafood consumers in the region.

Differential accumulation of microplastics in the gills and gastrointestinal tract of fish species of commercial and ecological importance in the Colombian Caribbean Sea
AI summary Read the abstract
Scientists found tiny plastic particles (microplastics) in the guts and gills of virtually every fish they tested from Colombia's Caribbean coast, including species people commonly eat. The plastics, likely from textiles, fishing gear, and packaging, were more abundant during rainy season and varied by fish species and size, suggesting that seafood in this region is widely contaminated with microplastics that could potentially make their way up the food chain to humans who eat fish.
