Investigating variability among fisheries litter accumulation on beaches in Paraná, Brazil.

Fishing activities strongly influence coastal and marine environments and are responsible for generating marine litter. In southern Brazil, there are several artisanal (small-scale) fisher settlements that potentially contribute towards regional marine litter. The present study sought to address the deficit in available information by investigating the in situ contribution of artisanal fishing communities to marine litter on adjacent beaches. During one month in the 2019 austral winter, 200-m stretches of beach were investigated at four locations (three artisanal fishing and one control community) in Paraná state. In total, 2196 items were collected; among which only 104 (<5 %) were fisheries related and these remained partially independent of the presence of the three fishing communities across both small and large spatial scales (i.e., from m to km). Rather than the presence of fishing communities, fisheries-related litter appears to primarily originate from external sources and may regionally accumulate via natural vectors such as oceanic currents.
