“…Debris load and items recorded may be influenced by the methods used to quantify such debris. As opposed to the above studies that use marine based surveys, Yorio et al (2014) and Hardesty et al (2017) used a more traditional beach survey methodology to quantify RFMD. In a protected area of coastal Argentina, 55% of marine debris resulted from recreational fishing and was composed predominantly of 243 balls of tangled monofilament line (Yorio et al, 2014).…”

“…Aside from the aesthetic and economic impacts, plastic waste also poses a hazard to navigation and a threat to the health and safety of humans and wildlife. Regarding the latter, the potential of plastic products and fragments for entanglement, strangulation and ingestion are well-documented for fish, birds and mammals (Carson, 2013;Yorio et al, 2014;McIntosh et al, 2015). Less understood, however, is the role of plastics in providing a vector for exposure to and accumulation of chemicals that are adsorbed to or incorporated within the polymeric matrix.…”

Plastics, foams and ropes collected from beaches in SW England have been analysed for As, Ba, Br, Cd, Cl, Cr, Cu, Hg, Ni, Pb, Sb, Se, Sn and Zn by field-portable-x-ray fluorescence spectrometry. High concentrations of Cl in foams that were not PVC-based were attributed to the presence of chlorinated flame retardants. Likewise, high concentrations of Br among both foams and plastics were attributed to the presence of brominated flame retardants. Regarding heavy metals and metalloids, Cd and Pb were of greatest concern from an environmental perspective. Lead was encountered in plastics, foams and ropes and up to concentrations of 17,500μgg(-1) due to its historical use in stabilisers, colourants and catalysts in the plastics industry. Detectable Cd was restricted to plastics, where its concentration often exceeded 1000μgg(-1); its occurrence is attributed to the use of both Cd-based stabilisers and colourants in a variety of products.

“…In the macroscopic analysis, the ingestion of two fishing gear was confirmed, an impact already described by Yorio et al (2014). The two hooks found were of the simple hook type, which is used in recreational fishing, a common practice in the region where the animal was rescued.…”

Impact of recreational fishing on seagull (Larus dominicanus) rescued on the coast of the São Paulo state: case report

The seagull (Larus dominicanus) commonly can be observed near human fishing activities, as this species feeds on discards from fishing. This common interaction between a seabird and human fishing activity (both commercial and recreational), provides an easy source of food, but is not without risk for the birds. We report here clinical, radiographic and anatomopathological findings of an esophageal perforation caused by fishing gear in a specimen of Larus dominicanus found alive on a beach in the state of São Paulo which illustrated a harmful effect of stemming from recreational fishing. Clinical examination revealed a nylon thread in the oral cavity with the presence of caseous suggestive of ingestion of lost fishing gear, paralysis of the pelvic limbs and a decrease in the pain reflex associated with sternal decubitus, suggestive of food intoxication. Necroscopic examination revealed two hooks, one in the caudal portion of the esophagus with esophageal and pulmonary perforation, and the other in the muscular stomach. These injuries would have been expected to lead to the death of the bird. These anatomopathological findings confirmed the seriousness of the injuries. This reinforces the importance of studies focused on the interaction of recreational fishing artifacts (hooks, lines) with coastal birds on the Brazilian coast, in order to develop a preventative strategy.
