Tsikopoulou et al (2026) Integrating benthic ecological status and spatial planning to guide sustainable bottom-contacting fisheries in the Eastern Mediterranean Frontiers in Marine Science
This study evaluates how different spatial management measures for bottom trawling could affect seabed ecological status in the Eastern Ionian Sea. Using fishing effort data and habitat sensitivity, the authors estimated the Relative Benthic Status (RBS) indicator, which measures the condition of benthic ecosystems. Results show that benthic habitats in the region are already in relatively good condition, with RBS values above the threshold for Good Environmental Status. Most tested spatial closures, such as deeper trawling bans or protecting lightly fished areas, produced little or no ecological improvement. The largest improvements were observed under a ban on trawling shallower than 150 m but the significant socio-economic impacts it would imply was highlighted. The study also finds that banning bottom trawling in marine protected areas may lead to the displacement of fishing effort to nearby areas, potentially increasing pressure on alternative fished grounds. The authors therefore question the effectiveness of a blanket political ban of bottom trawling in all MPAs. As an alternative, they encourage targeted protection of sensitive habitats and adapted fisheries management measures.
