Fishery for squids in ICES divisions VII e,f,g & h (English Channel, Bristol Channel and Celtic Sea) has been scored moderate risk. This is because vulnerability of these squids as assessed by SealifeBase is generally moderate, and little is known about population trends of particular species. It is worth noticing that vulnerability of 50 for T.sagittatus is not applicable for fisheries in ICES area VII as the species does not reproduce there and is just a seasonal visitor. The high vulnerability of 56 for L.forbesi seems also to be an over-exaggeration for ICES area VII, and likely it might be drawn from a recent decrease in species numbers in the southern part of the range, off Portugal, due to climatic changes. However, this process was accompanied by an increasing trend in abundance in the northern part of the species range and by relative stability in the English and French waters (Chen et al., 2006; ICES 2013; ICES 2015 unpublished).
The management of the squids in ICES areas VII e,f,g & h has been scored a moderate risk. This is because data from prosecuting fisheries and research surveys are collected regularly, but are not adequate for the stock assessment that would be required to inform management of these populations. There are no management measures in place to restrict catch of a particular species involved into this multi-species fishery because there is no species-specific reporting, though surveillance of fisheries in the area is at the highest level.
The bycatch risk of this fishery has been scored moderate risk. This is because squids represent a bycatch of larger demersal otter trawl fisheries targeting finfish in which discarded undesirable bycatch can represent over a quarter of the total catch. Squid discards (bycatch of the bycatch) are highly variable between fleets.
The habitat risk of this fishery has been scored a moderate risk. This is because demersal otter trawls are in regular contact with seabed, and otter doors both penetrate seabed and cause seabed abrasion, and surface abrasion caused by ground gear, sweeps and bridles. However, vulnerable habitats are protected by a coherent network of Marine Protected Areas.
