A longline survey was undertaken in the area relevant to the Sheringham Shoal Offshore Wind Farm export cable between the 27th and 29th of August 2013. The survey methodology replicated that of the August 2010 pre-installation survey, and the November 2012 post-installation survey, and was carried out to minimise the potential for seasonality affecting the post-installation results. The objective of the survey was to assess whether the operational export cable has any discernible effects on the localized population of elasmobranchs, and the feeding behaviour of lesser spotted dogfish (Scyliorhinus canicula). The survey was conducted using the same vessel, gear and bait, and at the same time of year as the pre-installation survey, however in this instance a single starry smoothhound (Mustelus asterias) was the only elasmobranch caught. One dab (Limanda limanda) was also caught. Both individuals were sized and recorded.
