Microplastics in water and fish of commercial interest: Distribution and relation to ecology in the colombians caribbean region, south america
Summary
Researchers evaluated microplastic contamination in surface waters and the gastrointestinal tracts of commercially important and invasive fish species along the Colombian Caribbean coast and San Andrés Island, examining the relationship between microplastic distribution and species ecology and geography.
Microplastics (MPs) are pollutants found in most of the world's marine ecosystems, causing environmental, economic, social, and cultural damage. This study focused on the coast of the Atlántico department and San Andrés Island in Colombia, evaluating microplastic contamination in surface waters and the gastrointestinal tracts of two commercially important fish species and one invasive species, while examining the relationship with the geographical distribution and ecology of these species. Eight sampling points were established per department, with sampling conducted in contrasting seasons (rainy and dry). A total of 128 water samples and 236 fish samples were collected, including Caranx crysos, Euthynnus alletteratus, and Pterois volitans. The surface waters of the Atlántico and San Andrés stations showed high MP contamination, with levels ranging from 0.2 to 11.8 MPs/m³ and 0.1 to 78.6 MPs/m³, respectively. In fish, the prevalence of MP ingestion was 82.6 Also see: https://micro2024.sciencesconf.org/559667/document

Microplastics in water and fish of commercial interest: Distribution and relation to ecology in the colombians caribbean region, south america
Researchers evaluated microplastic contamination in surface waters and the gastrointestinal tracts of two commercially important fish species and one invasive species along the Caribbean coast of Colombia's Atlantico department and San Andres Island, relating distribution patterns to the ecology and geographic range of each species.
Widespread microplastic ingestion in Colombian Caribbean marine fish: Trophic influence, spatial-temporal trends, and polymer composition
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.
Methods to characterize Microplastics: Case study on freshwater fishes from a tropical lagoon in Colombia
Researchers examined microplastic prevalence, abundance, and physical and chemical characteristics in fish from Luruaco lagoon, Colombia, conducting four sampling events using trawl nets and analyzing gastrointestinal tracts of captured individuals to characterize microplastic ingestion across species.
Impact of contamination due to ingestion of microplastics on commercial fish in relation to their trophic habits
Researchers evaluated the ingestion of microplastics by 28 Sciaenidae and 12 Ariidae fish species from estuaries in Tumaco and Buenaventura Bay, Colombia, examining stomach contents of 1,652 specimens across high and low precipitation seasons in 2020-2021 and analyzing how trophic level and other biological characteristics influence microplastic uptake.
Microplastic pollution in water, sediments and commercial fish species from Ciénaga Grande de Santa Marta lagoon complex, Colombian Caribbean
Microplastics were detected in water, sediment, and fish from the Ciénaga Grande de Santa Marta lagoon in the Colombian Caribbean, with concentrations varying by matrix and site. The study represents an early baseline for plastic pollution monitoring in this ecologically important tropical lagoon ecosystem.
