Saving the Seabed: the UK Push to Ban Bottom Trawling in Protected Waters

Beneath the grey waves of the seas around the United Kingdom lies a hidden, colourful world of cold water coral, forests of seaweed and gardens of anemones. Much of it is meant to be protected. Yet across many of these so called protected areas, heavy fishing nets still scrape the seabed bare, and now the government is moving to change that.

What bottom trawling does

Bottom trawling drags heavy weighted nets across the seafloor, scooping up the target fish along with almost everything else in the way. In the path of these nets, reefs that took centuries to grow, burrows and delicate seabed habitats are flattened, sometimes taking decades to recover if they recover at all.

The trouble is that a Marine Protected Area drawn on a map does not always mean real protection in the water. In many of the country's protected zones, bottom trawling has remained perfectly legal, leaving fragile seabeds exposed to some of the most damaging fishing gear in use today.

A plan to protect 30,000 square kilometres

In 2025, the government announced its intention to ban bottom trawling across 41 offshore Marine Protected Areas in England. The environment secretary, Steve Reed, unveiled the plan at the United Nations Ocean Conference held in Nice, presenting it as a major step for the health of the seas.

The measure would extend protection to around 30,000 square kilometres of seabed. Added to fishing limits that already exist in some areas, it would bring meaningful safeguards to a vast stretch of the offshore waters that surround the coast, far beyond the sight of anyone on the shore.

Twelve weeks of public debate

To turn the idea into rules, the Marine Management Organisation, working alongside the environment department, opened a public consultation on the ninth of June 2025. It ran for twelve weeks into late September, inviting fishers, scientists, campaigners and ordinary citizens to have their say on the future of the seabed.

The reaction pointed to a strong public appetite for healthier seas. Conservation groups such as the Wildlife Trusts reported wide support for stronger protection of marine life, describing the moment as a rare and golden opportunity to act before more damage is done to the ocean floor.

Why the seabed matters

The seabed is far from empty mud. It is a living foundation of cold water corals that grow over centuries, sponge gardens, shellfish beds and quiet nursery grounds where young fish shelter and grow before they ever venture out into the open water of the deeper sea.

For a nation that draws so much of its food and livelihood from the sea, this hidden layer is quietly essential. Healthy seabeds mean more fish in the future, more carbon locked safely away in the sediments, and coastlines that stand up better to the storms of a changing climate.

Protection on paper and in practice

Campaigners have long argued that the network of 178 Marine Protected Areas must mean more than lines drawn on a chart. Studies have shown that supposedly protected seabeds still endure tens of thousands of hours of industrial fishing in a single year, an activity hard to square with the word protected.

Closing the gap between protection on paper and protection in practice sits at the very heart of the trawling debate. Banning the most destructive gear inside these zones is seen by many marine scientists as the single clearest and most effective step that can be taken right now.

A test for the country's seas

The outcome will shape far more than fish stocks alone. It is a test of whether a country can turn the comforting promise of protection into a living reality, and whether its richest and most fragile underwater habitats will finally be given the chance to heal and recover.

Out of sight beneath the surface, the seabed has waited a very long time for relief. Whether the reefs, anemones and shellfish of these waters finally receive it may depend on decisions being made on dry land, far above the pull and sway of the tide.
