Formal Consultation – MMO management of fishing activity impacts in marine protected areas – Stage 3

Closes 1 Sep 2025

4.7 South-West Deeps (West)

This section is for specific responses in relation to South-West Deeps (West) MPA. 

If you have general comments for MPAs in the Western Channel and South West please place these in the region - regional comments’ section.

Alternatively, if your comments are overarching, for the consultation as a whole, please place these in the ‘General comments’ section.  

A summary for South-West Deeps (West) MPA, the Stage 3 MPA Fisheries Assessment, associated Impact Assessment (De minimis Assessment), methodology and draft byelaw can be found in the related information section below. Three Impacts Evidence documents can also be accessed in the related information section, describing the interactions between different fishing gear types and designated MPA features.

The map of the management area for this site can be found below. WebApps displaying the management areas alongside site data have also been produced. Access the WebApps here, guidance on their use can be found in the related information section below.

As detailed on the overview page, we have provided guidance questions which may help with structuring your response:

  1. Do you have any additional information about the location, condition, or sensitivity of the designated features?
  2. Do you have information on the type, location, frequency, or intensity of fishing activity within the MPAs?
  3. Do you agree or disagree with the proposed management measures? Do you have any suggestions for other management measures?
  4. How would the proposed management measures affect you? Or those you represent?
  5. What impacts, if any, do you anticipate the proposed management measures will have on UK fishing vessels, operators, or supply chains?
  6. What impacts, if any, do you anticipate the proposed management measures will have on non-UK fishing vessels, operators, or supply chains (including those from the EU)?
  7. What other impacts could the proposed management measures have? For example, on fishers, the wider fishing community, coastal communities, employment, upstream and downstream supply chains, people with protected characteristics under the Equality Act 2010, fish stocks, the marine environment.

Related Information

South-West Deeps (West) MPA is a marine conservation zone (MCZ) covering 1824 km2 located in south west waters, offshore of 12 nm off the south west coast of Cornwall. Part of the MPA borders the median line with Irish waters. Its designated features are:

  • fan mussel;
  • subtidal coarse sediment;
  • subtidal mixed sediments;
  • subtidal mud; and
  • subtidal sand.

There is also the designated feature ‘Celtic Sea relict sandbanks’ however geological features are not being considered in this assessment.

The MMO draft site assessment concludes that ongoing fishing using bottom towed gear over all features may result in a significant risk of hindering the achievement of the conservation objectives of the MPA.

The MMO draft site assessment also concludes that ongoing fishing using anchored nets and lines and traps will not result in a significant risk of hindering the achievement of the conservation objectives of the MPA.

MMO is therefore proposing a prohibition of the use of bottom towed gear throughout the MPA and a small buffer zone around the MPA.

This measure is included in the draft Western Channel and Southwest Marine Protected Areas Fishing Gear Byelaw 2024.
