European lobster

This stock is data limited and the stock status of European lobster in the Irish Sea is unknown. There is concern for biomass (owing to lack of any data) but no concern for fishing pressure.At present, there is no stock assessment available for European lobster in the Celtic Sea. Landings data provided by the Marine Management Organisation (MMO) show that landings of European lobster in the Celtic Sea from Welsh vessels remained stable between 2015-2019 between 62 and 83 tonnes per year. European lobster has a high resilience to fishing pressure.

This assessment is for the European lobster fishery beyond 6nm in the Celtic Sea, in Wales. Some national management measures are in place, however, they are not effective in managing the stock.In Wales, there are some management measures in place, but there are no catch limits in place to prevent overexploitation. There is no limit on creel numbers, no spatial controls and no Total Allowable Catch (TAC) for either the fishery as a whole, or individual vessels.All vessels registered in the UK must have a domestic fishing vessel license to fish within the UK EEZ for sea fish that will be sold. No new licenses are being issued. All commercial vessels under 10m, with a shellfish license, are required to complete Monthly Shellfish Activity Return (MSAR) forms for the Marine Management Organisation (MMO). These must include the catch and retained weight each day along with the date, name of vessel, vessel registration number, gear type, area and port of landing. All vessels over 10m do not need to complete MSAR forms as they will be completing a logbook of catches. For all vessels, effort is reported as days fished, and not as pots fished.In Wales, you do not need a permit to fish commercially for crabs and lobsters.National legislation in England and Wales also prohibits the landing of berried lobsters and those with a v-notch in their tail fan. V-notching of lobsters requires removing a V-shaped piece of exoskeleton from the uropod (inner tail flap) of female lobsters of reproductive size which are carrying eggs, then returning the lobster to the sea. This allows other fishermen to know not to land this lobster as it is reproducing. In Wales, there is a minimum conservation reference size (MCRS) for European lobster of 90mm carapace length.The Marine Conservation Society views Remote Electronic Monitoring (REM) with cameras is one of the most cost-effective tools for providing reliable fisheries data and aiding informed management decisions. Fully monitored fisheries enhance collaboration, data accuracy, stock recovery, and reduce impacts on marine wildlife and habitats. However, the full potential of REM may only be achieved when it tracks fishing location and documents catch and bycatch, particularly where vulnerable species and habitats are at risk. As of January 2024, the EU is introducing a Remote Electronic Monitoring (REM) mandate for EU vessels, including CCTV cameras on vessels 18m or more that pose a potential risk of non-compliance, within the next 4 years. Across the UK, different approaches to REM are being taken and legislation is expected to be in place across all 4 countries within the next few years.The Fisheries Act (2020) requires the development of Fisheries Management Plans (FMPs) (replacing EU Multi-Annual Plans) in the UK. 43 FMPs have been proposed and are at various stages of development and implementation, these should all be published by the end of 2028. FMPs have the potential to be very important tools for managing UK fisheries, although data limitations may delay them for some stocks. It is also essential the UK governments define and adopt a standardised approach or model across the four nations to a universally defined FMP design, to ensure the consistence, quality and coherence of all the proposal FMPs.The Marine Conservation Society is keen to see publicly available Fishery Management Plans for all commercially exploited stocks, especially where stocks are depleted, that include:An overview of the fishery including current stock status, spatial coverage, current fishing methods and impactsTargets for fishing pressure and biomass, and additional management when those targets are not being met, based on the best scientific evidenceTimeframes for stock recoveryImproved data collection, transparency, and accountability, supported by technologies such as Remote Electronic Monitoring (REM)Consideration of wider environmental impacts of the fishery, including habitat impacts and minimising bycatchStakeholder engagement

Pot fishing is generally considered very low impact as it is selective for larger individuals and has minimal impact on the surrounding environment.In the UK, brown crab and European lobster are fished together in a mixed fishery with seasonal and regional variation of target species taking place. The key fishing season for European lobster in the UK takes place in summer and autumn. Lobsters are caught in pots, also known as creels, and can be fished individually or as part of a fleet of up to 100 pots, depending on the size of the boat and crew. Pots are portable traps made of wood or steel wire and plastic. The lobster is baited into the initial part (the chamber) and moves into the secondary part (the parlour) where it becomes trapped.In European lobster fisheries, there is no legislation or regulation to standardise the type of pot used. They tend to be highly selective as undersized animals can be returned to the sea alive and survival rates for non-target organisms are thought to be high. More than half of the bycatch caught are predicted to survive, although there is little available research to prove this. Measures to further reduce bycatch include the use of escape panels to allow undersize animals and bycatch to escape pots.Habitat impacts from potting are low but can occur during deployment, soak time or hauling of the pot, impacting the benthic habitat and associated species through contact with the pot or end weight, or by scouring from ropes. Research that has taken place suggests that while some damage does occur, it is unlikely to be significant unless potting intensity is high (defined as approximately 30 pots per 500 square metres). Most damage occurs where traps are set in rocky habitats that are home to corals, sponges, sea whips and other large emergent species. These habitats and species provide nursery areas, refuges from predators and habitat for the settlement of invertebrate spat.In some circumstances, there can be instances of ghost fishing, when lost fishing gear continues to fish and can entangle a variety of species, but this can be minimised by using appropriate gear and release devices.The type of bait used in crab and lobster fishing is dependent on the area and availability of suitable products. Common bait species include mackerel and herring. However, there is concern that a significant amount of unreported bycatch from net fisheries are also being used as bait. This can include wrasse, conger eel, and low value species such as dogfish. Bycatch taken in creels, such as cephalopods, are also known to be used as bait. The environmental impact of this is unknown.
