The survey contributes to a programme of environmental monitoring at the site designed in response to conditions of the Food and Environment Protection Act (FEPA) Licence issued to the developer. The 2008 survey provides the third set of annual 4m beam trawl survey data designed to sample demersal fish present in and around the wind farm and at reference sites. This was the first survey during the operational phase of the wind farm and results have been compared with pre-construction (baseline) and during-construction surveys in preceding years. The 4m trawl surveys have detected no major impact of wind farm construction and initial period of operation on the distribution of fish locally. This is concluded based on high levels of similarity between catches pre, during and post-construction across sites and is consistent with the project Environmental Impact Assessment which did not anticipate major effects.

The survey was carried out using twin 4m commercial beam trawls (Figure 2) with 80mm mesh cod-end and a chain matrix between the beam and footrope. Trawling was carried out over a distance of approximately 2km (30 minutes) over the ground at a speed (c. 3 knots) deemed to be efficient for the capture of fish and in keeping with the previous methodology of the 2006 and 2007 surveys. Once the trawl distance had been completed and the gear retrieved to deck, the contents of the cod-ends of each trawl were emptied into port and starboard bins, where any sediment could be washed off. One at a time, these bins were tilted so that the contents poured gradually onto a conveyor belt, which ran into the whale-back on the bow of the vessel where the contents of the trawl could be sorted on a second conveyor belt. Discards of the trawls dropped into a chute at the end of the second conveyor belt that emptied at sea-level. The port trawl was used in all of the trawls except trawl 1 as the port net had a large hole in it. Each trawl and any species of interest were photographed (see Appendix 4). As the catch passed along the conveyor in the whale-back (Figure 4), all fish were sorted from the trawl contents by the onboard CMACS representatives (experienced Marine Biologists). Benthic epifauna were not considered in this survey and were returned to sea via the chute previously described. The fish from each trawl were photographed in boxes and then counted, all commercial fish species with the addition of dab Limanda limanda were measured, elasmobranchs were sexed and measured.
