Microplastic contamination in striped catfish (Pangasianodon hypophthalmus) from water, sediment, and feed in aquaculture ponds
AI summary
`query_candidates/2` filters `is_nil(p.abstract) or p.abstract == ""` and `not is_nil(p.doi) and p.doi != ""`, orders by `desc: p.relevance_score, asc: p.id`. The secondary `asc: p.id` is a sensible tiebreaker addition.

Microplastic Contamination in Aquaculture: Sources, Ecological Effects, and Future Solutions
AI summary Read the abstract
Researchers reviewed the sources and ecological impacts of microplastic contamination in aquaculture systems, finding that plastic particles under 5 mm originate from multiple aquaculture inputs and raise serious concerns for environmental sustainability and the safety of seafood for human consumption.
Microplastics in catfish Pterygoplichthys pardalis (Castelnau 1855) and Hoplosternum littorale (Hancock, 1828) marketed in Itacoatiara, Amazonas, Brazil
AI summary Read the abstract
Researchers found microplastic contamination in 85% of Pterygoplichthys pardalis and 83% of Hoplosternum littorale catfish collected from Amazon floodplain markets in Brazil, with polyethylene terephthalate and polystyrene fibers being most prevalent and present throughout the fish body including viscera. Because these species are commonly consumed whole by Amazonian riverside communities — including internal organs — they represent a direct and culturally significant route of microplastic ingestion for populations with limited alternative protein sources.
Microplastics in Aquaculture Systems and Their Transfer in the Food Chain
AI summary Read the abstract
Researchers reviewed how microplastics accumulate throughout aquaculture systems — the fish farms that produce much of the world's seafood — and traced how these particles move up the food chain to reach human consumers, raising concerns about the safety of farmed seafood.
Biomarker-assisted evaluation of toxicity of co-exposure of emergent pollutants triclosan and microplastics in striped catfish, Pangasianodon hypophthalmus
AI summary Read the abstract
A 45-day exposure study in striped catfish found that co-exposure to triclosan and polystyrene microplastics suppressed immune function, elevated oxidative stress markers, increased tissue accumulation of triclosan, and caused haematological abnormalities compared to either contaminant alone. The synergistic toxicity observed when microplastics act as vectors for antimicrobial chemicals has implications for aquatic ecosystem health and for the safety of farmed fish consumed by humans.
Microplastic Impacts in Fisheries and Aquaculture
AI summary Read the abstract
Researchers reviewed evidence that fish and seafood destined for human consumption are ingesting microplastics, documenting the breadth of contamination across commercially important species and what it means for the safety of seafood that billions of people eat regularly.
