This study measured levels of microplastics in the gastrointestinal tracts of 34 fish from eight different deep-sea by-catches, finding that 48% of samples contained at least one microplastic item, with polyethylene being the most common. This preliminary study provides new data on microplastics ingestion by species inhabiting a deep-sea environment in the Mediterranean.
Concern about microplastic pollution little is known about levels in deep-sea species; to fill this knowledge gap, levels of microplastics in the gastrointestinal (GI) tracts of 34 fish from eight different deep-sea by-catches: blackmouth catshark, lesser spotted dogfish, and velvet belly, armless snake eel, hollowsnout grenadier, phaeton dragonet, royal flagfin, and slender snipe eel were measured. All were collected at the same site (east Sardinia, Mediterranean Sea; 40 degrees 10'12.49 '' N, 9 degrees 44'12.31 '' E) using a bottom gillnet at depths between -820/250 and -1148 ft./350 m. Microplastics (MPs) were retrieved in 16 out of 34 fish. At least one microplastic item was found in 48% (33%, E. spinax - 75%, G. melastomus) of the samples. The most frequent was polyethylene (PE), with nine items (filaments, films, fragments) found in five specimens. This preliminary study of by-catches adds new data on MPs ingestion by species inhabiting a deep-sea environment of the Mediterranean.
