“…This phenomenon can have a devastating impact on marine ecosystems and is a serious problem that has been around for centuries [66][67][68]. Han (2023) reported that nets and ropes were commonly entangled on rocks or corals of rocky intertidal zones, were difficult to remove, and negatively impacted benthic ecosystems [43]. Fishing nets can be fatal to marine organisms that become trapped but they are difficult to retrieve from the ocean floor [30].…”

“…This makes SMD collection more expensive and time consuming [42]. In terms of submerged marine debris management, swimmers equipped with snorkels can monitor the sea surface, coastline, and shallow seabeds [2,43]. Bottom trawl surveys using echo and video devices can be used to assess the amounts and types of benthic debris in the deep sea [22,28,39,[44][45][46][47][48].…”

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.
