Fishing plastics: A high occurrence of marine litter in surf-zone trammel nets of Southern Brazil

Mar Pollut Bull. 2021 Dec;173(Pt A):112946. doi: 10.1016/j.marpolbul.2021.112946. Epub 2021 Sep 17.

Abstract

Plastic is one of the most commonly found residues in the marine environment, which can cause several impacts. This study evaluated the interaction of marine litter with surf-zone trammel nets in Southern Brazil. Fifty fishing operations were sampled, where 4213 items were captured: 1500 discarded fish, 1384 fragments of marine litter, and 1329 utilized fishes. Plastics were the most abundant items (n = 1363), representing 98.4% of the registered marine litter, especially plastic bags (n = 1191). 94.5% of registered marine litter is considered as single-use waste. The interaction with marine litter can cause negative impacts to small-scale fisheries (e.g. economic and damage to fishing nets). We highlight the urgency in implementing actions for urban solid waste management and public policies to reduce single-use plastics and educational campaigns on the environmental theme.
