Ocean Conservation and Stewardship

Jim Shannon Excerpts

Tuesday 15th September 2026 Westminster Hall

[Tristan Osborne (Chatham and Aylesford) (Lab) [R]]

I beg to move,

That this House has considered ocean conservation and stewardship.

It is a pleasure to serve under your chairmanship, Dr Murrison. We spend a lot of time in this place talking about land, housing and farms—what grows and what gets built. We spend less time talking about the three quarters of a million square miles of ocean that fall under UK jurisdiction. That is a mistake, because our seas are the foundation of a great deal of our national life. They regulate our climate, feed our coastal towns, carry our trade and increasingly hold the key to this country’s resilience in the decades ahead.

As vice-chair of the all-party parliamentary group for the ocean, I watched David Attenborough’s documentary on the oceans alongside many colleagues in this House and the former Prime Minister. I echo Attenborough’s words that

“We are living in the greatest age of ocean discovery, yet we are also witnessing its greatest peril.”

I am the Member of Parliament for Chatham and Aylesford, and my constituency has a centuries-long maritime history through its association with the dockyard and global trade. That is highlighted by the outstanding work of the Chatham Historic Dockyard Trust in its recent “Awesome Oceans” exhibition with Steve Backshall, which seeks to educate our younger generations. Our nation’s heritage runs through our seas and oceans.

I want to use my time to cover four key elements: the state of our marine protected areas and bottom trawling within them, fisheries and sustainability, the case for parity in marine pollution fines, and the UK’s wider leadership role in the ocean, including in the recently signed biodiversity beyond national jurisdiction agreement and the plastics treaty negotiations.

[Jim Shannon (Strangford) (DUP)]

I thank the hon. Gentleman for bringing this issue forward. My constituency based on the scenic Northern Ireland coastline, and I am particularly interested in what more can be done to protect the sea that surrounds us. Raw sewage contains bacteria, harmful chemicals and microplastics, all of which have serious consequences for both marine and human health. Those microplastics are essentially impossible to remove once they enter the environment. Does the hon. Gentleman agree that more must be done to tackle the problem of microplastics?

[Tristan Osborne]

I do agree. The UK Government’s engagement on the global plastics treaty, in alignment with the European Union and other nations, is looking to resolve that exact issue. Microplastics that get into the human biology can significantly heighten the risk of cancer and other problems, and they are a persistent form of pollution that needs to be resolved.

Let me start with a number that should give every Member in this room pause. A third of UK waters now sit within a marine protected area. On paper, that sounds like a country taking marine conservation seriously; in practice, however, the Government’s own assessment finds that we are failing on 13 of the 15 indicators of good environmental status in our seas, and not one of our offshore habitats is currently assessed as in good condition. How can that be when so much of our sea is supposedly protected?

The honest answer is that designation is not always the same thing as protection. Across large parts of the MPA network, bottom trawling and dredging remain entirely lawful. Oceana estimates that, in 2024 alone, there were more than 31,000 hours of suspected bottom trawling in UK offshore marine protected areas. More than 70% of those hours were concentrated in just 41 English sites—the same 41 sites covered by the Government’s stage 3 consultation. That consultation ended some time ago, and fishermen, conservation groups and coastal communities responded to it in good faith, so will the Minister provide a clearer timetable for the publication of the outcome?

Bottom trawling deserves a moment of its own, because it is not a marginal or peripheral issue. Heavy gear dragged across the seabed flattens reefs, uproots seagrass and disturbs carbon that has been locked in the sediment for centuries. It is, by some distance, one of the most destructive things that we allow in our oceans.
