Sky News and Global Fishing Watch have discovered many of the UK's marine conservation zones and marine protected areas are often protected in name only. Since January 2022, tens of thousands of hours of damaging fishing practices like dredging and bottom trawling have taken place in the so-called protected zones.

Although damaging to our ocean's havens, the practices aren't illegal. So how can we allow commercial fishing to continue while allowing our seabeds to recover and thrive?

On this week's ClimateCast, Tom Heap is in Bognor Regis to speak to fourth-generation fisherman, Clive Mills, who has returned to his fishing boat after being pushed out because of a lack of supply. Twenty years on, he's pledged to only fish sustainably and is encouraging others to do the same.

Plus, we look at the state of fishing in our waters internationally with Jack Clarke from the Marine Conservation Society.
