offshore cable corridor within the 12nm limit; based on consultation, activity in the East Anglia THREE site is lower. Therefore with respect to the under 15m fleet the assessment considers impacts associated with the offshore export cable only. Similarly, consultation and VMS data sets (Figure 14.43, Figure 14.47 and Figure 14.48) indicate that the majority of activity by the UK over 15m otter trawl fleet is focussed around the offshore cable corridor. Activity recorded in the East Anglia THREE site by UK vessels over 15m is negligible. It is also considered that a significant amount of activity (as represented by VMS data -Figure 14.47 and Figure 14.48) in this area will actually be from the Anglo-Dutch Beam trawl fleet, although this is not possible to quantify as data is not separated by method.
231. The under-15m vessels are considered to be of mediumsensitivity, due to their limited operational range, dependence on a limited number of fishing grounds, and a reduced potential to mitigate the loss of fishing area by operating in alternative areas.
232. Over-15m vessels (between 20m and 24m) are based mainly at the east coast ports of Grimsby and Scarborough and target a range of species. These vessels have a wider operational range than under-15m vessels and a higher degree of method and target species versatility. As such they are assigned a low sensitivity. The offshore cable corridor constitutes a small proportion of the grounds available to the under- 15m fleet (Figure 14.59, Figure 14.63 and Figure 14.68), and the effect would be temporary. The magnitude of effect for under-15m vessels is therefore considered to be low.
233. In the case of the over-15m vessels, it is understood that they fish the area under consideration infrequently, with the majority of their effort being concentrated in the Central and Northern North Sea (Areas IVb and IVa). These vessels are therefore unlikely to be exposed to the impact of temporary loss or restricted access to fishing grounds, and would be able to mitigate any potential loss of small fishing area by operating in alternative areas (Figure 14.41). The potential effect is therefore considered to be of negligible magnitude.
234. The impact of loss or restricted access to fishing grounds for both the UK under-15m demersal otter trawl fleets during construction / decommissioning phases is considered to be ofminor adverse significance and for the over 15m demersal otter trawl fleet to be negligible.
Static Gears and Drift Netting 235. The local fleet is almost entirely comprised of under-10m vessels based at local ports along the Suffolk and Essex coasts which have limited operational ranges in
