A report published in September 2023 by Oceana, a conservation NGO focused on restoring the world’s oceans through influencing government policy decisions, states that half of the UK’s key fish populations are overfished or in a critical state.

Of the 104 different fish stocks that were analysed in the report, 34 per cent are being over-fished while 25 per cent of UK fish stocks are in a critical condition. The report goes on to state that only 41 per cent of UK fish populations are of a healthy size. But even here, six fish stocks that were a healthy size in 2020 have now declined to a critical state, and, since 2020, only three stocks have moved from being critically low to healthy.
