Demersal trawling; and Seine netting.
14.5.3.1 Beam Trawling2 Figure 14.5 shows the distribution of Dutch beam trawl landing values (€) in the
North Sea. Activity by the beam trawling fleet is widely distributed throughout the North Sea, with the highest values occurring in the Southern North Sea. Both the East Anglia THREE site and the offshore cable corridor are situated in the proximity of high value beam trawling grounds, with the highest values being recorded immediately south of the East Anglia Zone.
14.5.3.2 Demersal Otter Trawling3 The distribution of Dutch demersal otter trawling is shown in Figure 14.6. Similar to
49.
the beam trawl fleet, activity is widely distributed throughout the North Sea. Landings values from the proposed East Anglia THREE project are low compared to those from grounds located to the east and further north in the central North Sea.
14.5.4 Dutch Fishing Activity – Regional overview
14.5.4.1 Surveillance sightings 50. MMO surveillance data displayed in Figure 14.4 shows that the majority of Dutch vessels within the vicinity of the proposed East Anglia THREE project are beam trawlers. Sightings are most dense in an area to the west of the East Anglia THREE site; those within the site itself are somewhat lower. Sightings of Dutch vessels in the offshore cable analysis area (33F2) are generally low. Increased beam trawling activity is recorded immediately south of the offshore cable corridor.
14.5.4.2 Fisheries Statistics The Fisheries statistics provided by IMARES and shown in Figure 14.7 show that in the windfarm and offshore cable analysis areas, the majority of landings values are
51.
2 Beam trawling involves the towing of steel beams held off the sea bed by shoes or rollers at each end, onto which the net is attached. This principal has been progressed further by the development of ‘sum wing’ and ‘pulse wing’ trawls where the net and chains are attached to a hydrofoil rather than a beam. On pulse wing gear the chains are replaced with electrodes. Further information on gear specification and operational practices are provided in Appendix 14.1.
3 Demersal otter trawl is a towed gear comprised of a funnel shaped net held open by trawl (‘otter’) doors. The ground line of the net is weighted to maintain contact with the sea bed and can vary in design depending on the type of ground fished. Further information on gear specification and operational practices are provided in Appendix 14.1.
