Megrim in the Celtic Sea, West of Ireland, and Bay of Biscay is in a healthy state and fishing pressure is within sustainable limits. Two species of megrim are landed, with Lepidorhombus whiffiagonis being more common. There are management measures in place, but, catch limits apply to both species of megrim which hinders the ability to prevent overexploitation of either species. Total catches have been equal to or below the advice. Otter trawling is likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species.Rating last updated July 2022.

There are management measures in place, but, catch limits apply to both species of megrim which hinders the ability to prevent overexploitation of either species. Total catches have been equal to or below the advice. Beam trawls have significant impacts on the seabed, including damage to benthic communities and vulnerable marine habitats. They can also have high bycatch, potentially of vulnerable species.Rating last updated July 2022.

Megrim in the northern North Sea and West of Scotland is in a healthy state and fishing pressure is within sustainable limits. Megrim are mainly caught as part of the targeted fishery for monkfish or anglerfish, and as bycatch in fisheries for demersal species such as cod and haddock. The advice is given for two species of megrim combined, as they are caught together, however, available information indicates that L. boscii are a negligible proportion of catches. While fishing is within sustainable limits, management measures (Total Allowable Catches) do not match up to the stock areas, which could in theory allow overfishing to take place. Otter trawling is likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species.Rating last updated July 2022.

In Rockall, megrim biomass is at a healthy level and the stock is harvested sustainably. Some, but not all, appropriate management measures are in place. A mismatch between stock and management areas may lead to overexploitation of the stock. Otter trawling is likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species.Rating last updated November 2023.
