Presence of microplastics and microparticles in Oregon Black Rockfish sampled near marine reserve areas.

Measuring the spatial distribution of microparticles which include synthetic, semi-synthetic, and anthropogenic particles is critical to understanding their potential negative impacts on species. This is particularly important in the context of microplastics, which are a form of microparticle that are prevalent in the marine environment. To facilitate a better understanding of microparticle occurrence, including microplastics, we sampled subadult and young juvenile Black Rockfish () at multiple Oregon coast sites, and their gastrointestinal tracts were analyzed to identify ingested microparticles.
