Abstract
AbstractCommercial fisheries yield essential foods, sustain cultural practices, and provide widespread employment around the globe. Commercially harvested species face a myriad of anthropogenic threats including degraded habitats, changing climate, overharvest, and pollution. Microplastics are pollutants of increasing concern, which are pervasive in the environment and can harbor or adsorb pollutants from surrounding waters. Aquatic organisms, including commercial species, encounter and ingest microplastics, but there is a paucity of data about those caught and cultured in North America. Additional research is needed to determine prevalence, physiological effects, and population‐level implications of microplastics in commercial species from Canada, the United States, and Mexico. Investigations into possible human health effects of microplastic exposure from seafood are also greatly needed. This synthesis summarizes current knowledge, identifies data gaps, and provides future research directions for addressing microplastics effects in commercially valuable North American fishery species.

This article is an invited paper to the Special Issue: Microplastics in marine and freshwater organisms: Presence and potential effects Edited by: Dr Elise Granek, Portland State University, Dr Susanne Brander, Oregon State University, and Dr Erika Holland, California State University, Long Beac
We present the top commercial fishery species by North American country (Fig. 2; Supporting Information Appendix 1), display and describe which species have existing data on microplastics contamination and/or effects (Fig. 3, Table 1), and identify priority research areas to better understand ecological and human health risks of microplastics in North American commercial fishery species
There have only been six North American-based laboratory studies published, which aim to determine the propensities of shellfish to intake or egest microplastics (Table 1)
