11.5.4 International Beam Trawl Surveys (IBTS) 40.


The 50 most common species present in the East Anglia THREE specific study areas (Figure 11.1), expressed as their average relative abundance (CPUE) in IBT surveys (spring, summer, autumn, winter) for the years 2004-2013 is given in Table 11.11. For all species, data are mean values from combined quarterly surveys (spring, summer, autumn, winter) from 2004-2013.


41. High CPUEs were recorded for sprat in the offshore cable corridor and the East Anglia THREE site. Sand goby CPUE was highest in the offshore cable analysis area. Herring CPUE was highest within the windfarm analysis area, but low in the offshore cable analysis area. Relatively high CPUEs were also recorded for greater sandeel Hyperoplus lanceolatus in the offshore cable analysis area.
