- Stock Status
Turbot in Division VIIe, f, j, h and sub area VIII and IXa has been scored as high risk. This is because turbot has a medium vulnerability score and the population trend is unknown due to the limited information available.
The management of Turbot in Division VIIe, f, h, j and sub area VIII and IXa has been scored a high risk. This is because there are no management decisions or assessments of stock status for turbot, there is only minimal data being collected and there are no specific management measures in place to restrict harvesting. However, there are management measures in place to control effort in the fisheries.
The bycatch risk of this fishery is scored as high risk. This is because otter trawls have the potential to take relatively high quantities of bycatch of non-target and vulnerable species (> 30% of catch weight), including demersal elasmobranchs and protected, endangered and threatened (e.g. sharks and rays) species in certain circumstances. However, the incoming EU landings obligation is intended to reduce discarding.
The habitat risk of this fishery is scored as a moderate risk. This is because, although otter trawls are considered to have a potential to cause significant habitat damage, damage to vulnerable and sensitive marine habitats is likely to be minimised given that the footprint of the fishery is within core areas, typically historically fished ground. Spatial management to reduce potential interactions with vulnerable habitats are being developed, but there remains uncertainties about the location of some sensitive seabed habitats and therefore some risk of further impact.
