Assessment of plastic ingestion by pole‐caught pelagic predatory fish from O'ahu, Hawai'i

Abstract

1. Although the frequency of occurrence of plastic ingestion in the large-sized dolphinfish and tunas taken by the Hawai'i longline fishery is very low (frequency

Breeding ecology, population size and nest site preferences of Red-billed Tropicbirds at St Helena, South Atlantic Ocean

“…Likewise, there were no observed negative effects of litter e.g. through entanglement or ingestion (Hyrenbach et al 2013;Vanderwerf and Young 2014) despite part of the mainland monitoring sites encompassing a disused refuse dump.…”

Identifying Potential High-Risk Zones for Land-Derived Plastic Litter to Marine Megafauna and Key Habitats within the North Atlantic

“…Macroplastic ingestion has been documented in many tuna species including yellowfin (Thunnus albacares) (Chagnon et al, 2018;Fujieda et al, 2014;Manooch and Mason, 1983;Sajikumar et al, 2013), bluefin (Thunnus thynnus) (Romeo et al, 2015;Varela et al, 2022;Yick and Travers, 2022), blackfin (Thunnus atlanticus) (Manooch and Mason, 1983), the little tunny (Euthynnus alletteratus) (Manooch et al, 1985), skipjack (Katsuwonus pelamis) (Hyrenbach et al, 2021;Neto et al, 2020), bigeye (Thunnus obesus) (Fujieda et al, 2014), and albacore (Thunnus alalunga) (Hyrenbach et al, 2021;Romeo et al, 2015) tunas. Both swordfish (Xiphias gladius) (Romeo et al, 2015) and the black marlin (Makaira indica) (Fujieda et al, 2008) have been also been documented to ingest macroplastic litter.…”

“…In the Mediterranean, Romeo et al (2015) found that 32.4 % of bluefin tuna (Thunnus thynnus) and 12.5 % of swordfish (Xiphias gladius) caught in the Mediterranean contained macroplastic fragments in their stomachs (Romeo et al, 2015). Plastic objects were generally fragments or sheets (Hyrenbach et al, 2021), such as pieces of plastic bag (Sajikumar et al, 2013), sweet and food wrappers (Varela et al, 2022) and fragments of food containers (Yick and Travers, 2022).…”
