144. Blonde rays are of less commercial importance in UK landings in comparison to thornback rays. They are also landed with thornback ray and spotted ray by the Dutch beam trawl fleet (ICES, 2007). The species is classified as ‘Near Threatened’ in the IUCN Red List of threatened species (Table 11.9).


11.5.10.4 Common Skate Complex 145. The common skate complex (Dipturus intermedia and Dipturus flossada) were historically amongst the most abundant ray species in the north-east Atlantic, with a wide distribution around the British Isles. They have now disappeared from the Irish Sea, English Channel and the southern and central North Sea. Individual specimens are reported occasionally from these areas, however they are now only regularly observed off northern and north-western Scotland, Celtic Sea and along the edge of the continental shelf (more than 150m deep) (Dulvy et al. 2006).


146. Common skate complex is classified as ‘Critically Endangered’ by the IUCN Red List of Threatened Species. In addition, they are listed as a UK BAP priority species and in the OSPAR list of threatened and / or declining species (Table 11.9).


11.5.11 Elasmobranchs – Sharks


11.5.11.1 Small spotted catshark/ lesser spotted dogfish 147. Small spotted catsharks, more commonly known as lesser spotted dogfish occupy a variety of mixed sediment and on rocky reefs. They are widespread around the British Isles, they are common at depths from 3 to 110m (Kay and Dipper, 2009). The distribution of lesser spotted dogfish is considered to be patchy (Ellis et al. 2005).


148. Lesser spotted dogfish was one of the more abundant species found in the area of the East Anglia THREE site during the site specific otter trawl surveys (Table 11.2) and beam trawl surveys (Table 11.3). Commercial landings in the local study area for this species are comparatively low, with lesser spotted dogfish being included under the category “other” in Table 11.5 and Table 11.6.


149. Live egg cases are mostly laid between November and July, although can be found throughout the year. The species primarily feed on crustaceans, including a variety of crab and shrimp species, molluscs and polychaete worms. Benthic fish species also form part of their diet (Wheeler, 1978).
