The South West brown crab MCRS online survey

Thank you for taking the time to complete this short online survey. Your participation is appreciated.  

The survey is open from 31 July and closes at 23:59 on 17 August 2025. 

Overview 

Through previous work to deliver the crab and lobster Fisheries Management Plan (FMP) (opens in new tab), it is proposed to permanently harmonise the minimum conservation reference size (MCRS) for brown crab in the South West.    

Please see the supporting document on our Regional Fisheries Groups – South West 7efg website (opens in new tab) for more information, including how this option was selected and next steps. This survey is designed to gather your views, and your feedback will help shape how and when this measure could be introduced. 

MCRS option 

The government is proposing the permanent harmonisation of the MCRS for brown crab in the South West brown crab area. This would establish: 

• An MCRS of 160 millimetres (mm) for male brown crab 

• An MCRS of 150 mm for female brown crab 

This measure would apply to all UK and EU commercial fishing vessels. 

The proposed management area extends west of 2.946333°W longitude, which marks the eastern boundary of the Devon and Severn Inshore Fisheries and Conservation Authority (IFCA) district, and south of 52.000°N latitude. It encompasses English waters from mean high water springs to the extent of the UK Exclusive Economic Zone (EEZ) in the South West region. 

Opportunities and benefits of this option: 

• Enhanced stock sustainability: Increased opportunity for female brown crab to spawn, supporting long-term growth in stock biomass. 

• Simplified and consistent regulation: A single, harmonised MCRS provides clarity and assurance for fishers, regulators, and supply chains. 

• Regionally focused management: Supports evidence gathering on regional approach, helping to inform any future management approaches.
