Abstract
Ingestion of macroplastics by common dolphinfish (Coryphaena hippurus) in the Atlantic Ocean
Highlights
The anthropogenic impact of pollution by plastic debris has threatened marine life inhabiting benthic and pelagic habitats from the poles to the equator (e.g., Ryan and Moloney, 1993; Derraik, 2002; Thompson et al, 2004)
The interaction of plastic debris with marine life is expected, and their ingestion has been documented in a wide range of marine organisms, including zooplankton, bivalves, fish, turtles, birds, and marine mammals (Azzarello and Van-Vleet, 1987; Lusher et al, 2015; Romero et al, 2015; Egbeocha et al, 2018)
There are several possible reasons for the consumption of plastic debris by marine fish, including mistaking plastic for food because the odor of plastic in the sea is like that of food (Savoca et al, 2017), confusing it with prey species associated with floating plastic material while feeding on them, and preying on smaller organisms that have previously ingested plastics (Possato et al, 2011; Varghese et al, 2013)
Summary
Ingestion of macroplastics by common dolphinfish (Coryphaena hippurus) in the Atlantic Ocean. Ocean and Coastal Research 2021, v69:e21015 1 being removed from an ecosystem, play an important role in the trophic structure (Olson and Galván-Magaña, 2002; Varghese et al, 2013) Since this species is commonly associated with floating offshore objects, for example, fish aggregating devices or floating beds of Sargassum spp., it is an easy target for fisheries worldwide (Manooch et al, 1984; Massutí, et al, 1998; Rudershausen et al, 2010; Brewton et al, 2016). This study is the first to report on the largest macroplastic debris found in the stomach of the common dolphinfish, C. hippurus in the Southwest Atlantic Ocean. The classification of the plastic debris into mesoplastic (5 mm–25 mm) and macroplastics (> 25 mm) was completed according to Rodrigo-Seijo and Pereira (2017)
