trawl effort. This suggests that beam trawlers achieve higher landings values per unit effort (e.g. more fish for fewer days at sea); a reflection of increased catching capacity and the targeting of high value species such as sole.
101. Beam trawls are also the principal method used to target plaice and sole in the offshore cable analysis area. Midwater pair trawls record much lower values which correspond to those observed previously for sprat. Landings values recorded by methods such as longlines, otter trawls and gillnets are somewhat lower.
102. In the inshore cable analysis area, fish species are targeted by a more diverse range of gear types. Longlines represent the greater proportion of values, followed by beam trawls, gillnets and both categories of otter trawl. Longlines are principally used to target cod and will account for a proportion of thornback ray and bass landings. In addition to sole, landings values recorded by beam trawls, gillnets and otter trawls will also be formed by varying amounts of these species.
103. Figure 14.44 shows landings values by length category in the vicinity of the proposed East Anglia THREE project. With specific reference to the windfarm analysis areas it is interesting to note that whilst the over-15m fleet records three quarters of the landings values (most likely Anglo-Dutch vessels), the majority of the remainder is formed by vessels in the under-10m category. This proportion is similar to that recorded for longlines (see Figure 14.39) indicating a number of vessels using this gear type are in the under-10m fleet. Landings values in the offshore cable analysis area originate almost entirely from vessels in the over-15m category (most likely Anglo-Dutch vessels). In contrast, approximately two thirds of landings values in the inshore cable corridor are from the under-10m fleet. The distribution of effort by vessel category supports these conclusions (Figure 14.46).
104. Further information on fisheries statistics in relation to the UK fleet is provided in the Appendix 14.1.
14.5.11.3 VMS Data
105. Based on previous analysis of effort and landings data, a significant proportion of activity recorded in the vicinity of the proposed East Anglia THREE project is by vessels under-15m in length. This is particularly true of the inshore areas of the cable corridor. As VMS satellite data are only representative of the activity of vessels over-15 metres in length a significant proportion of activity close to shore will not be represented by MMO datasets.
