The Scottish government has initiated a public consultation that could lead to the ban on bottom-trawl fishing across 20 offshore marine protected areas (MPAs).

This move aims to protect Scotland's vulnerable marine ecosystems from the "destructive" effects of bottom trawling, a fishing method which can damage seafloor habitats and cause significant bycatch, according to NGO Oceana UK.

Proponents of bottom-trawling, though, argue the scientific evidence shows any changes made to the seabed are far less impactful than claimed.

For 15 of these MPAs, the government is considering two potential approaches: a complete site-wide ban on bottom trawling or a more targeted ban that protects specific features, such as reefs, within the sites. For the remaining five MPAs, a full site-wide ban is being proposed.

Hugo Tagholm, executive director of Oceana UK, welcomed the consultation.

"These ocean havens are home to some of Scotland's most incredible marine wildlife, and this is our chance to restore, replenish and regenerate Scotland's seas. The Scottish government's consultation on this vital issue is welcome and much needed," he said.

He argued that Scotland's seas, already under pressure from climate change, pollution, and overfishing, urgently need fully protected areas to recover and build resilience.

Oceana's analysis revealed that Scottish offshore MPAs experienced almost 6,000 hours of suspected bottom trawling in the past year, with the West of Scotland and Geikie Slide MPAs being the most heavily affected. Oceana and other conservationists have urged the Scottish government to implement site-wide bans to give these ecosystems a real chance of recovery.

Similar measures are expected to be proposed in English waters later in 2024, Oceana said. The consultation remains open to public input.
