Demersal trawling; and Seine netting.
14.4.3.1 Beam Trawling2 Figure 14.5 shows the distribution of Dutch of beam trawl landings in the North Sea.
Activity by the fleet is widely distributed throughout all areas although values in the south exceed those recorded in the north by up to four orders of magnitude. Both the East Anglia THREE site and the offshore cable corridor are also situated in the proximity of high value beam trawling grounds. Exceptionally high landings are recorded immediately south of the East Anglia Zone.
14.4.3.2 Demersal Otter Trawling3 The distribution of Dutch demersal otter trawling is shown in Figure 14.6. Similar to

the beam trawl fleet, activity is widely distributed throughout the North Sea. Landings values from the East Anglia THREE zone are low compared to those from grounds located to the east and further north in the central North Sea.
14.4.4 Dutch Fishing Activity - Regional
14.4.4.1 Surveillance Sightings Figure 14.4 shows that the majority of Dutch vessel observations within the vicinity

of the proposed East Anglia THREE project are of beam trawlers. Sightings are densest in an area to the west of the East Anglia THREE site; those within the site itself are somewhat lower. In addition to beam trawlers, fly seiners (seine netters) and unspecified trawlers have also been recorded within the East Anglia THREE site, albeit in significantly lower numbers.
60. Sightings of Dutch vessels in the offshore cable corridor are generally low but
increase in the eastern section. Increased beam trawling activity is recorded immediately south of the offshore cable corridor. Demersal trawlers have been recorded in low numbers inside the East Anglia Zone. It is likely that a significant number of ‘unspecified’ trawler sightings were in fact of demersal trawlers, though
2 Beam trawl is a towed gear comprised of steel beams held off the seabed by shoes or rollers at each end, onto which a net is attached. This principal has been progressed further by the development of ‘sum wing’ trawl where the net and chains are attached to a hydrofoil rather than a beam. Further information on gear specification and operational practices are provided in section 14.4.5.2.
3 Demersal otter trawl is a towed gear comprised of a funnel shaped net held open by trawl doors. The ground lines of nets are weighted to maintain contact with the seabed and can vary in design depending on the type of ground fished. Further information on gear specification and operational practices are provided in section 14.4.5.2.
