Fishmeal as a pathway for microplastics to the marine environment from capture fisheries via fishmeal production to mariculture feed. Food particles (open circle), microplastics (red filled circle). Microplastic fragmentation possible during fishmeal production steps (heating and grinding) or through contamination, leading to increased microplastic concentrations fed back into the environment.
