Abstract
Ghost nets constitute a serious threat to aquatic biodiversity, because they entangle animals as long as they persist in the environment. However, scientific literature in Brazil is virtually silent about this issue in inland ecosystems. Concerned with this gap, we conducted searches on YouTube BR to gather information about ghost nets in Brazilian freshwaters. Through our search, we compiled 33 independent videos showing ghost nets in different aquatic environments. In several cases, we identified entangled animals (i.e., fishes, reptiles, and birds). In this work we also provide recommendations to better understand and mitigate this problem in Brazilian freshwater ecosystems.

The continuous degradation of aquatic ecosystems is a growing concern (e.g., Pelicice et al 2017, Albert et al 2021)
Here we report some cases of ghost nets in Brazilian freshwaters based on data retrieved from the internet
We found 33 videos showing the presence of ghost nets in different waterbodies, from streams to reservoirs
Summary
The continuous degradation of aquatic ecosystems is a growing concern (e.g., Pelicice et al 2017, Albert et al 2021). One important problem is the incorrect disposal or loss of fishing nets (Matsuoka et al 2005), which creates ghost nets that continuously entangle aquatic animals in the environment (Smolowitz 1978, Iriarte & Marmontel 2013). Several scientific works have been published for Brazilian estuarine and marine ecosystems (e.g., Adelir-Alves et al 2016, Santos et al 2012, Chaves 2021). Concerned with this gap, here we report some cases of ghost nets in Brazilian freshwaters based on data retrieved from the internet
