Metadata: 2006, Centre for Marine and Coastal Studies (CMACS), Burbo Bank Offshore Wind Farm, Pre-Construction Commercial Fish Survey (4m Beam Trawl)
Abstract:
This project relates to the specific FEPA requirements for surveys of subtidal benthic (seabed) invertebrate ecology and fish. These are in part addressed by an annual 2m scientific beam trawl survey which complements other work, notably grab sampling and 4m (commercial) beam trawl surveys. The 2m beam trawl survey is undertaken by Centre for Marine and Coastal Studies Ltd (CMACS) on behalf of SeaScape Ltd. The programme commenced with baseline (pre-construction) surveys in autumn 2005 which built upon surveys undertaken in 2002 in support of the project environmental impact assessment. This project relates to the results of monitoring carried out in autumn 2006, during construction of the wind farm, and compares the results with baseline data. The survey outcomes showed some clear differences in benthic fauna sampled by beam trawls that were apparent between baseline survey in 2005 and the during construction survey in 2006. The most notable trend was a marked decrease in abundance of epibenthic invertebrates and infauna sampled by trawls across many sites.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The survey was carried out over 3 days from 1st to 3rd May 2006 aboard the fishing vessel â??Admiral Grenvilleâ?? operating out of the East Canada Dock in Liverpool. The survey was carried out using twin 4m commercial beam trawls with 80mm mesh cod-end and a chain matrix between the beam and footrope. Trawling was carried out over the ground at a speed of 3.5-4 knots, after consultation with the vesselâ??s captain, Richard Hamilton, who advised that this speed was most efficient for the capture of fish. Trawling was carried out for 30 minutes over a distance of 2km. Once the gear had been 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 4 as the port catch was lost in this case. Each trawl and any species of interest were photographed (see Appendix 4.2 and 4.3). As the catch passed along the conveyor in the whale-back, all fish were picked out of the trawl contents by the CMACS representatives on board. 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. |
