We recognise the disruption the octopus bloom is causing to crab, lobster, and scallop fisheries in the region.
Following initial meetings with regulators, scientists and stakeholders a number of actions are being progressed in response to the Southwest Octopus bloom.
Gathering insights
MMO is monitoring landings of octopus, as well as key stocks impacted by in increased presence of octopus, such as crab, lobster, scallops, crawfish and whelks. Landings data has been presented in the infographics below and will be routinely updated.

MMO and Defra have met with representatives from Marine Biological Association to discuss the proposed octopus research project and are considering how best to support.
MMO will undertake a review of global octopus fisheries.
MMO is exploring advice from research papers on best handling practice, much of the existing advice refers to octopus husbandry from a scientific guidance stance.
MMO are in the process of acquiring additional species ID cards, which will be made available upon request from local MMO offices.
In response to the current octopus bloom the MMO have been looking at ways to support industry.
We have been asked by stakeholders to clarify the position for vessels subject to Western Waters (WW) crab regime when fishing for other species such as octopus.
If fishing for a species other than crab/spider crab such as octopus and you only land that species and discard any crab/spider crab, then an effort day won’t be counted.
For vessels landing even minimal amounts of crab then WW days will continue to count.
Please ensure you continue to record any discards of crab. Including whole dead, whole live, or predated shell fragments.

South West Crab Trial Group
The SouthwestSouth crabWest trialCrab groupTrial Group was formed in 2024, facilitated by Seafish to bring together local stakeholders, MMO and Defra to help deliver aSouth West brown crab trial(s).
MMO drafted an options paper (below)(linked andbelow) thiswhich was circulated to the group on 15 May 2025. Online meetings took place on 3 and 5 June 2025 to discuss the optionspaper, next steps for crabengagement, engagementand octopus impacts foron thethis trial(s).trial(s) work. At the time the optionspaper was drafted octopus were not causing the level of concern that they are now.
There was unanimous support from the group for harmonising the Minimum Conservation Reference Size (MCRS), also referred to as the minimum landing size, for brown crab in South West English waters. The proposed harmonised MCRS is:
160 millimetres (mm) for male brown crab
150 mm for female brown crab
While there was recognition of the potential value of other measures, particularly those related to effort management, the group agreed that these should not be progressed this summer due to current challenges in the South West relating to the octopus bloom. MMO and Defra understand the importance of managing the crab stocks sustainably and will continue to work with industry through the implementation groups to progress effort management approaches as a priority. We are improving our data and understanding of the impacts of the octopus bloom on the fishery to inform the development of management proposals.
Originally, MMO planned to do a South West face-to-face roadshow in June to meet with industry to discuss brown crab trial options. However, based on feedback from the group we will instead conduct a short online survey to gather views.
A summary of the meetings and next steps is provided below. This has been circulated to the SouthwestSouth crabWest trialCrab group.Trial Group.
Update and the South West brown crab MCRS online survey
Given the strong stakeholder support, and anticipated long-term benefits to crab stocks, the government intends to implement the proposed MCRS increase as a permanent measure, rather than a trial. This is subject to further stakeholder input.
MMO, on behalf of Defra, have launched a mobile-friendly online survey that should take no more than 5 minutes to complete. The online survey is a new way of consulting with stakeholders.
Please use the link below to complete the survey. You’ll also find a consultation overview document provided for your reference.
Although stakeholders have indicated that now is not the right time to explore alternative crab trial options, MMO will improve our data and understanding of the fishery to inform effective management in the region. Defra and MMO aim to continue developing effort management proposals with national and regional groups, and resume discussions with the wider industry.
Projects
Lyme Bay Sole Fishery
Between 2015 and 2022 quota for Dover sole (Solea solea) in the International Council for the Exploration of the Sea (ICES) Area 7.e roughly doubled, leading to increased fishing effort in particular in Lyme Bay. Concerns were raised by stakeholders about the effects of this increased effort on the sole population, the wider marine environment, and local communities. As a result, the MMO agreed to undertake a review of the Lyme Bay sole fishery from an environmental, social and economic perspective. This review included analysis of landings and at sea observer data, a consultation and 2 in person workshops with stakeholders to discuss potential new management measures for the fishery.
Following analysis of the consultation responses, workshop and evidence investigations, MMO has published a decision document outlining the results, proposed management measures and next steps. MMO has also produced a one-pager to summarise the outcomes of consultation and proposed management measures. Please see below for the documents and further detail.
We commissioned Cefas to carry out a desktop study to look at increased mesh sizes for both static and towed gear in 7e and whether this results in larger sole being caught and therefore supporting the sustainability of the stock. WeThere willwere communicatelimited samples to make a significant conclusion that an increase in mesh size would be beneficial and only a very small percentage of catches are below the results28cm suggested MCRS. The report suggests that an increase in mesh sizes or MCRS would have minimal impact on the wider health of the stock. Recognising stakeholder feedback and ourpractical nextexperience, stepsthe soon. report has been delivered to the Celtic Sea & Western Channel Demersal FMP team to include within their evidence base for sole and consider for future measures alongside evidence gathering.
We’ve also delivered this report to Defra, noting the potential benefits of an increased mesh size in the sole fishery for bycatch of pollack.
In January 2024, the MMO introduced the ‘Text Anna’ anonymous reporting of gear conflict. The person reporting the conflict will be kept anonymous.
Fishers, both commercial and recreational, should text Anna (SW RFG Lead) on 07584 885 023 with the following information:
What gear was damaged or lost (pots, nets, lines etc).
Coordinates of where the gear was damaged or lost.
Any information that was spotted on the markings to identify the owner of the gear
You can also use this online form for reporting lost or damaged gear in Lyme Bay instead.
MMO only count reports where there has been damage to gear. We do not consider competition for space / inability to launch gear, a ‘gear conflict’.
Code of Conduct
The MMO has responded to concerns from fishermen that an increase in sole quota has led to conflict and potentially overfishing in Lyme Bay.
The MMO and Inshore Fisheries Conservation Authorities (IFCA) have been investigating and in 2022 created a steering group to oversee the investigation. The Steering group includes representative fishers from the Lyme Bay Community Interest Company, and other ports outside of Lyme Bay, as well as the Department for Environment, Food and Rural Affairs (Defra), IFCA, Centre for Environment, Fisheries and Aquaculture (Cefas) and MMO representatives.
At a steering group meeting in the summer of 2022, a best practice Code of Conduct for sole fishing with gill nets in Lyme Bay was agreed as follows. Lyme Bay is defined as the area inside a line from Beer Head to Portland.
A minimum mesh size 5 inches (127mm) for gill nets targeting sole.
All fixed nets should be marked with a buoy showing the PLN of the vessel at both ends of the net.
Flags and radar reflectors are used where possible and practical to mark the location of nets.
Note: That these are best practice recommendations and not law.
The first recommendation is to support the sole population by letting smaller soles increase their opportunity to breed. The second is to help prevent gear conflict by increasing the visibility of net locations to prevent them being caught up in trawl gear, and so that other netting vessels can avoid setting nets that cross over nets already set in the water.
Small eyed ray (RJE) investigation to explore removal of 7e non-retention
This was the first project to come from the RFGs. Inshore fishers in the Southwest Regional Fisheries Group raised the local abundance of small-eyed ray in area 7.e and the rationale behind the non-retention policy in 7.e when it can be retained in 7.f-g. The non-retention policy is the result of a political decision at EU level, it was not based on ICES advice.
The MMO commissioned Cefas to carry out a study, this was paid for by MMO evidence team. The study highlighted that there is no evidence of decline in the stock, distribution is patchy as is trawl survey data due to its preferred habitat. Small-eyed ray is not a significant stock nationally or financially but could be significant to coastal communities in the southwest particularly inshore fishers.
The Defra Negotiations team took this to the EU at the annual negotiations in December 2023 and received a limited quota for small-eyed ray (RJE) in the western English Channel (ICES Division 7.e) to allow for scientific data collection. In 2024, this was used by Cefas to carry out a self-sampling scheme in collaboration with commercial, inshore fishers, to collect information on the species composition of skates in those inshore areas where small-eyed ray is locally common, and information on the size composition, sex ratio and biology of small eyed ray.
We are hoping to work with Cefas to carry out a similar scheme for 2025.
Fisheries Management Plan Q&A Videos
Following on from recent Fisheries Management Plan (FMP) events, four Q&A videos have been produced for FMPs currently under consultation.
The RFG team has gathered answers to common questions to help provide clarity on key elements of the plans and to assist with fishers completing the consultations. The videos feature answers from Defra policy leads, with input from Cefas, AIFCA, and the Marine Management Organisation.
In 2024, MMO worked with industry to address concerns for the crawfish fishery in the southwest. Stakeholder engagement events and consultations were held regarding seasonal closures of the fishery. The first closure took place between 05 February 2024 to 30 April 2024. The second closure took place between 16 December 2024 to 31 May 2025.
In December 2024 the licence condition for the increased minimum conservation reference size ‘MCRS’ (minimum landing size) of 110 millimetres (mm) was succeeded by a statutory instrument (SI).
MMO has opened a consultation for a seasonal closure during winter 2025 to spring 2026. The consultation is open until midnight on 20 July 2025.
