“…Several studies worldwide observed a high percentage of entanglements in litter associated with fishing activity [5,8,41,55,56,64,65]. In line with our observations, Mghili et al [41] highlighted that fishing-related litter constituted the majority (89%) of entanglements documented in the Moroccan Mediterranean.…”

“…Among the categories of marine animals entangled, we found a limited number of cases involving teleost and elasmobranchs. The entanglement of these groups of organisms was reported in the scientific literature [52][53][54][55]. Specifically, entanglements of sharks in circular plastic debris was reported for several species (Galeocerdo cuvier, Isurus oxyrinchus, Prionace glauca, Carcharhinus galapagensis) [56,57].…”

Abandoned, lost, or otherwise discarded fishing gear (ALDFG) is a primary contributor to the entanglement of numerous marine species. Utilizing digital media platforms like Google, Facebook, and Instagram we conducted an assessment of the detrimental effects of ALDFG and plastic litter, on the biodiversity of Italy's marine ecosystem. Our investigation revealed that plastic litter has adverse consequences on various forms of marine life, including reptiles, mammals, birds, fish, crustaceans, and mollusks, along different Italian geographical sub-areas. Several records of interaction between plastic and endangered and vulnerable marine species have been described. Our reports even highlight the impact on marine turtles, mainly on Caretta caretta. This is the first report of entangled with fishing nets in Cetorhinus maximus, Oblada melanura, Serranus scriba, Homarus gammarus, Octopus vulgaris, and Phoenicopterus roseus. Furthermore, we identified that ghost nets have repercussions for endangered and vulnerable marine species. This update sheds light on the ongoing adverse effects of ghost nets on the Italian marine ecosystem, yet it is crucial to acknowledge that the true extent of the problem remains underestimated.

“…Until now, information regarding abandoned fishing gear in the seas around Italy remains sparse and fragmented in terms of the number, weight, and geographical location [31,[88][89][90]. Nevertheless, fishing materials contribute to the mortality of numerous marine species, as demonstrated in studies by Pace et al [91], Perroca et al [85], and the current investigation.…”

“…However, it is important to note that these data are likely underestimated, as Mghili et al [52] pointed out the challenges in accurately assessing the true extent of entangled fish due to their rapid cadaver decomposition. Perroca et al [85] documented over 40 fish species entangled in ghost fishing in the Mediterranean Sea, emphasizing the widespread issue. Additionally, larger marine mammals and turtles are more commonly reported on social media compared to fish entanglements.…”

Plastic litter is a global threat affecting all marine ecosystems. Utilizing digital media platforms like Google, Facebook, and Instagram we assessed the detrimental effects of marine plastic litter on the biodiversity of the Italian marine ecosystem. We noted that marine plastic litter had adverse consequences on marine reptiles, mammals, sea birds, fish, crustaceans, and mollusks, including endangered and vulnerable marine species. The loggerhead sea turtle (Caretta caretta) was the most recorded species found entangled in plastic litter. Our investigation revealed that abandoned, lost, or otherwise discarded fishing gear are the primary contributors to the entanglement of numerous marine species. The current study represents a preliminary step towards establishing databases that document records of entanglement, which may be useful in adopting new conservation measures in the Mediterranean geographical subareas. Our results emphasize the critical need for collaborative efforts among all stakeholders and policymakers to effectively manage marine plastic litter.

“…Ghost fishing was also observed, and a variety of fish were trapped. Ghost fishing is caused by abandoned, lost, or discarded fishing gear that continues to capture and kill fish and other marine life [65]. This phenomenon can have a devastating impact on marine ecosystems and is a serious problem that has been around for centuries [66][67][68].…”

Pollution associated with marine debris is of global ecological concern, as it threatens wildlife and local economies. Submerged marine debris alters local benthic species composition and community characteristics. The study site of Jaguri, Jeju Island, where a variety of submerged marine debris was found, was used to investigate the impact of submerged marine debris on the macrobenthic fauna of sandy and rocky substrates. The dominant macrobenthos taxon differed by sediment type; the polychaete Armandia lanceolata was dominant in sandy bottom environments and the mollusk Leiosolenus lischkei was dominant in rocky bottom environments. The presence of marine debris was associated with differences in biomass in both the soft and rocky areas. The site without debris had higher biomass in the soft area, and the site with nets had a higher density of benthic animals within the site with debris. In the rocky area. the site with debris had a higher biomass. Macrobenthos were affected by the type of deposited marine debris and the type of sediment substrate. This study provides a basis for future studies on the impact of debris on marine ecosystems and identified the benthos species affected by marine debris.
