Ingestion and retention of biodegradable vs. non-biodegradable microplastics in a tropical coral reef fish: The role of chemical and physical characteristics
Summary
Researchers investigated how biodegradable and non-biodegradable microplastics differ in their ingestion and retention by a tropical coral reef fish species. The study assessed how polymer type, particle shape, size, and color influenced the fish's microplastic ingestion preferences and gut transit times. The findings provide experimental data on the physical and chemical characteristics that drive microplastic uptake in marine organisms.
This dataset contains experimental measurements from a study investigating the ingestion and retention of biodegradable and non-biodegradable microplastics (MPs) in juvenile tropical reef fish, Acanthochromis polyacanthus. The study assessed how polymer type (polystyrene vs. polycaprolactone), particle shape (films vs. fragments), size (100–400 μm), and colour (transparent vs. blue) influence MP ingestion preferences and gastrointestinal transit time (GTT). Data include: Individual fish identifiers and characteristics (e.g., weight, size) Type, shape, size, and colour of MPs offered Quantity and type of MPs ingested per fish after 2 h exposure Gastrointestinal transit time and depuration rate of MPs over 72 h Observed ingestion patterns and depuration dynamics for each polymer type The dataset supports the findings reported in: “Ingestion and retention of biodegradable vs. non-biodegradable microplastics in a tropical coral reef fish: The role of chemical and physical characteristics”, Marine Pollution Bulletin, MPB 119346. These data provide detailed information for understanding how polymer-specific physical traits influence ingestion and retention in reef fish, offering a valuable resource for replication studies, meta-analyses, and further research on microplastic pollution and the evaluation of biodegradable plastics.

Ingestion and retention of biodegradable vs. non-biodegradable microplastics in a tropical coral reef fish: The role of chemical and physical characteristics
Researchers examined how biodegradable versus non-biodegradable microplastics are ingested and retained by juvenile tropical reef fish. The study measured how polymer type, particle shape, size, and color influenced ingestion preferences and gastrointestinal transit time. The dataset provides detailed experimental measurements that help clarify which physical and chemical characteristics of microplastics drive their uptake by marine fish.
Ingestion and retention of biodegradable vs. non-biodegradable microplastics in a tropical coral reef fish: The role of chemical and physical characteristics
Researchers compared how juvenile reef fish ingested and retained biodegradable versus non-biodegradable microplastics of varying shapes, sizes, and colors. The study found that fish preferred larger, transparent fragments regardless of polymer type, and surprisingly, biodegradable polycaprolactone microplastics persisted longer in the gut than conventional polystyrene, suggesting that biodegradability alone does not reduce retention risks in marine organisms.
Color preferences and gastrointestinal-tract retention times of microplastics by freshwater and marine fishes
Researchers examined microplastic color preferences and gut retention times in freshwater and marine fish, finding that fish preferentially ingested red, yellow, and green particles and that retention times varied significantly across species.
Ingestion and egestion of polyethylene microplastics by goldfish (Carassius auratus): influence of color and morphological features
Researchers studied how goldfish ingest and expel polyethylene microplastics of different colors, shapes, and sizes. They found that fish ingested more green and black particles than other colors, preferred film-shaped plastics over fragments, and rejected particles larger than 2 mm. Most ingested microplastics were expelled within 72 hours, though filament-shaped plastics took the longest to pass through.
Does color play a predominant role in the intake of microplastics fragments by freshwater fish: an experimental approach with Psalidodon eigenmanniorum
Researchers examined whether color influences microplastic ingestion by freshwater fish, finding that fish did not selectively ingest microplastics based on color and instead ingested particles indiscriminately, suggesting that visual selectivity is not a primary driver of microplastic uptake in freshwater species.
