“…For instance, only one study reported the entanglement and death of animals; two cetaceans in the Amazon basin (Iriarte & Marmontel 2013). In contrast, 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.…”

“…This is because animals could be entangled in abandoned fishing nets, blocking them from moving freely, needed sunlight, and causing their death (Wilcox et al 2015 ; Azevedo-Santos et al 2021 ). The affected animals are fish, birds, reptiles, and mammals (Stelfox et al 2016 ; Adelir-Alves et al 2016 ; Lima et al 2019 ; Azevedo-Santos et al 2021 ).…”

Plastic pollution presents a major challenge facing stakeholders and decision-making worldwide. Plastics in the ocean damage biodiversity and marine ecosystem services that the blue economy relies upon. The present work analyses and reviews the literature on plastic pollution and the background knowledge about marine plastic pollution in Morocco. The economy of Morocco depends mainly on marine activities, including fisheries, tourism, and maritime trade. These sectors were identified as the main in-situ sources of plastics entering Moroccan coastal waters. The analysis results showed that the increasing abundance of plastics in such marine systems causes substantial economic loss to blue economy activities. In contrast, the lack of data on the plastic waste quantity entering Moroccan water is a limiting factor for assessing plastic pollution. This highlights the need for a risk assessment and more field investigations to value the weight impacts of marine activities generators of plastics on biodiversity and the economy. In addition, implementing laws and rules forbidding the disposal of plastic waste (PW) in public spaces, mainly beaches, and streets, is urgently needed. Raising awareness of plastic waste management and prioritizing improved waste collection, sorting, and management would boost Morocco’s establishment and adoption of circular economy strategies. It is worth noting that while implementing the management projects and regulatory frameworks of plastic waste, considering their source and usage purpose is mandatory.

“…A growing concern about litter in aquatic systems has also been observed in Brazil, with reports for freshwater (Iriarte and Marmontel 2013;Azevedo-Santos et al 2022), oceanic (Santos et al 2012Grillo and Mello 2021), and coastal regions (Mascarenhas et al 2008;Machado and Fillmann 2010;Vieira et al 2011;Andrades et al 2020;Pinheiro et al 2021), and its subsequent impacts on estuarine fauna (Possatto et al 2011;Dantas et al 2012). There are also a few studies on derelict fishing gears and ghost fishing (Chaves and Robert 2009;Adelir-Alves et al 2016), including a review of ALDFG (Link et al 2019) and the negative impacts of ghost nets on Brazilian marine biodiversity revealed by digital media (Azevedo-Santos et al 2021). However, till now, a quantitative assessment of the direct impact of derelict fishing gears on marine resources had not been conducted in Brazil.…”

A ghost fishing experiment was conducted using gillnets in a rocky reef off the state of Santa Catarina, southern Brazil. Scuba divers monitored changes in the structure of the nets and catches for 92 days. One hundred and twenty-six entangled animals were observed, including target and non-target fishing species: 13 teleosts (N = 52; 43%) and four crustaceans (N = 74; 57%). The crab Menippe nodifrons was the most frequently entangled species (N = 36; 28%). Entanglement rates decreased over time following a logarithmic model for fishes and crustaceans, and an exponential model for both taxa combined, attributed to the degradation, and tangling of the nets and biofouling. The area of the net decreased linearly over time, collapsing after 92 days. This study provides the first experimental evaluation of the impacts of ghost fishing caused by gillnets in Brazilian rocky reefs.
