Microplastic in the Food of Small Sandeel Ammodytes tobianus from the Littoral of the Curonian Spit of the Baltic Sea
AI summary Read the abstract
This study examined microplastic occurrence in the small sandeel Ammodytes tobianus, a key forage fish in marine food webs, finding plastic particles in their digestive systems. Because sandeels are eaten by larger fish, seabirds, and marine mammals, their contamination has cascading implications for broader food chain microplastic transfer.
In the food bolus of small sandeel Ammodytes tobianus caught on the littoral of the Baltic Sea in the area of the Curonian Spit, two types of microplastic material were found—film and villus fibers. Microplastic was found in 21% of the studied individuals, and its portion is <0.01% of the mass of food. Microplastic film is defined with use of infrared spectra as polypropylene in the stage of destruction.

AI summary Read the abstract
This study documented microplastic ingestion in juvenile Chinook salmon and their forage fish in the Salish Sea, finding plastic particles across multiple species and providing early evidence of microplastic contamination entering Pacific salmon food webs. The findings highlight the potential for microplastics to affect commercially and ecologically important fish species.
