Blonde ray

Blonde ray in the North Sea and West of Scotland is data limited. There is concern for the biomass, and concern for fishing pressure.Route 2 (data limited) scoring has been applied to this rating owing to the lack of reference points. ICES cannot assess the stock and exploitation status relative to maximum sustainable yield and precautionary approach reference points because information to define reference points is not available. As there is no data to indicate stock trends, there is concern for the biomass.ICES advises that when the precautionary approach is applied, landings should be no more than 7 tonnes in each of the years 2024-2027. This is the same advice as that given for 2022 and 2023. Over the last 5 years, on average, landings have exceeded advice. Although they declined in 2022, there will be no more advice given for another 4 years and therefore, there remains concern for fishing pressure. Blonde ray has a low resilience to fishing pressure.

Blonde ray is a vulnerable species and management needs to be more precautionary. The joint TAC in place is not a suitable management method.There is no management plan in place for blonde ray in this area. Demersal elasmobranchs are usually caught as bycatch in the mixed demersal fisheries for roundfish and flatfish. Species identification issues between blonde ray and spotted ray may affect landings, observer and survey data.In 1999, a common Total Allowable Catch (TAC) for 'skates and rays' was first introduced. Five regional quotas are in place for the group of skates and rays, rather than for the individual species. This method of management has been deemed as unsuitable for protecting individual species, but species-specific quotas may also lead to discarding. In 2023, the TAC for skates and rays were set as follows:1,764 tonnes for ICES areas 2.a and 4 (68% UK)48 tonnes for ICES area 3.a9,797 tonnes for ICES areas 6.a, 6.b, 7a-c, and 7e-k (30% UK)1,537 tonnes for ICES area 7.d (16% UK)5,519 tonnes for ICES areas 8 and 9 (0.2% UK)In addition, in North Sea waters, vessels larger than 15m, are only permitted to land a maximum of 25% of the catch (whole weight) as skates and rays.Skates and rays caught in the Northwest waters (ICES subareas 6 and 7) and North Sea waters (ICES subareas 2a, 3a and 4) with all fishing gears, are exempt from the landing obligation, based on their high survivability rates. Any skates and rays that are discarded are required to be released immediately and below the sea surface.There is no official minimum conservation reference size (MCRS) in place but some of the UK's Inshore Fisheries and Conservation Authorities (IFCAs) have an MCRS of 40cm disc width for skates and rays.Both the EU and UK have fishery management measures in place, which can include catch limits, targets for population sizes and fishing mortality, and controls on what fishing gear can be used and where. In the EU, compliance with regulations has been variable, and there are ongoing challenges with implementing some of them. There was a target for fishing to be at Maximum Sustainable Yield by 2020, but this was not achieved.In the UK, it is too early to tell how effective management is, as the Fisheries Act only came into force in January 2021. The Act requires the development of Fisheries Management Plans (FMPs) (replacing EU Multi-Annual Plans) but there are no details yet on how and when these will be developed. FMPs have the potential to be very important tools for managing UK fisheries, although data limitations may delay them for some stocks. MCS is keen to see FMPs for all commercially exploited stocks, especially where stocks are depleted, that include:Targets for fishing pressure and biomass, and additional management when those targets are not being metTimeframes for stock recoveryTechnologies such as Remote Electronic Monitoring (REM) to support data collection and improve transparency and accountabilityConsideration of wider environmental impacts of the fishery

Otter trawling is likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species.Blonde rays inhabit offshore sandbanks and coastal shallows and occur over sandy, mud and gravel substrates. Blonde ray in this area also exclusively by bottom trawls (98%). It is not known how many are discarded.Demersal trawls have contact with the seabed, resulting in penetration and abrasion of habitat features. The impact of trawling on the seabed depends on where trawling happens, and on what scale. For example, habitats that are used to natural disturbance through tides and waves are less sensitive to impacts. Areas not used to mobile towed gears are typically more sensitive.Demersal otter trawls have the potential to take relatively high quantities of bycatch (> 40% of catch weight).There is a lack of information on what bycatch species are commonly found in this area but common bycatch in bottom trawls includes mixed crabs, urchins, lesser spotted dogfish, nursehound, dragonet, starry ray, and smelt. Endangered, threatened and protected (ETP) species including angel shark, blue skate and flapper skate have been depleted through fishing in this area.It's difficult to avoid catching skates and rays in nets and because of their peculiar shape and size, it's also difficult for them to escape the net once captured. Therefore, selectivity programmes are in place to reduce skate and ray catches and their survival rates. Discard rates of skates and rays can vary dramatically (30 - 70%), depending on the marketability and management measures in place. Nearly all skates below 30cm total length are discarded by English vessels.Bycatch can include juvenile skate as they can hatch from their egg cases between 10-20 cm total length and therefore, may be able to escape through the nets. The survival rate of juveniles upon discarding is extremely variable and depends on the fishing and handling methods used to capture them. Elasmobranchs have the potential for relatively high survival rates because they do not have swim bladders, and thereby are not impacted by water pressure changes. They can also have thick and abrasive skins and thorns for protection, and some have spiracles and a buccal-pump respiratory which excretes a mucus, allowing the skate or ray to ventilate and acquire oxygen when out of the water. Inshore and coastal fisheries using trawls, longlines, gillnets and tangle nets generally show low at-vessel mortality. There are a lack of studies available on long-term skate and ray survival when they are released into the wild.Habitat regulation measures across European waters include Marine Protected Areas (MPAs). If those MPAs were found to be subjected to bottom trawling, MCS would assign a default red rating unless there is evidence (e.g. through environmental impact assessment) indicating that the activity does not damage the integrity of the site. EU regulations prohibit bottom trawling below 800m and restrict activities between 400-800m. Spatial management is continually being developed, which will restrict the footprint of this gear on the seabed. However, there remains some uncertainty about the location of some sensitive seabed habitats so these remain at risk.To improve monitoring and reporting of fishing activity, MCS would like to see remote electronic monitoring (REM) with cameras implemented, used and enforced. To reduce the impacts of fishing on the marine environment we would like to see a just transition to the complete removal of bottom towed gear from offshore Marine Protected Areas designated to protect the seabed. We also want to see reduction and mitigation of environmental impacts including emissions and blue carbon habitat damage.
