Summary
Researchers investigated microplastic contamination in four varieties of commercial fish meal and then tracked the transfer of those particles to cultured common carp fed on the meal. They found microplastics present in all fish meal varieties, predominantly fragments of polypropylene and polystyrene, with particles transferring to the fish gastrointestinal tract and gills. The study highlights fish meal as a previously overlooked pathway by which microplastics can enter aquaculture and potentially the human food supply.
Microplastics (MPs) are environmental contaminants that are of increasing global concern. This study investigated the presence of MPs in four varieties of marine-derived commercial fish meal, followed by identification of their polymer composition using Fourier transform infrared (FTIR) spectroscopy. Exposure experiments were conducted on cultured common carp (Cyprinus carpio) by feeding four varieties of commercially available fish meal to determine relationships between abundance and properties of MPs found both in meal and in those transferred to cultured common carp. Mean particle sizes were 452 ± 161 μm (± SD). Fragments were the predominant shape of MP found in fish meal (67%) and C. carpio gastrointestinal tract and gills (65%), and polypropylene and polystyrene were the most present plastic polymers found in fish meal (45% and 24%, respectively) and C. carpio (37% and 33%, respectively). Positive relationships were found between MP levels in fish meal and C. carpio. This study highlights that marine-derived fish meal may be a source of MPs which can be transferred to cultured fish, thus posing a concern for aquaculture.
