14.4.12.1.2 Offshore Cable Analysis Area 157. Annual landings values by species in the offshore cable analysis area are shown in Diagram 14.32. Excepting 2003, 2007 and 2010, sole represent the highest landings values of all species but have shown considerable variability. Between 2003 and 2006 sole landings showed a tenfold increase in value (£183,087 to £730,049) then declined sharply in 2007 (£150,962) and 2008 (£68,224). Some recovery was recorded in 2009 (£361,925) and 2010 (£365,495), before values falling again in 2011 (£205,443) and 2012 (£12,640).
158. Landings values of plaice were highest from 2003 (£343,722) to 2007 (£180,473), with a peak value recorded in 2004 (£559,191); approximately equal to sole landings in the same year. Similar to sole, landings values then generally declined in the latter half of the time series. Landings values of other flatfish species such as brill and turbot generally map those of sole and plaice. The majority of these landings will be bycatch from the beam trawl fishery. The peak landings values for both species occurred in 2005 (brill: £72,252; turbot: £97,976) coinciding with those of sole.
159. Annual landings values of cod were highest in the first half of the dataset and peaked in 2003 (£153,921). It is worth noting that cod landings are generally of lower value than in the inshore cable corridor (33F1).
160. With respect to methods, Diagram 14.33 shows that in most years annual average landings values from the beam trawl fishery are an order of magnitude greater than those recorded by any other method. As plaice and sole are the target species of the beam trawl fishery respective landings values closely mirror one another. Landings values from the fishery exceeded £1,300,000 in 2004, 2005 and 2006, but were considerably lower in subsequent years following the same pattern of decline previously observed in sole values.
161. A broadly similar pattern is apparent between the value of landings derived from gillnets, longlines and those of cod (both used to the species) which show a general reduction from 2003 to 2007. Landings values originating from vessels operating midwater pair trawls only occur in 2005 (£140,013), 2008 (£21,841) and 2010 (£158,197) corresponding to landings values of horse mackerel (2005, 2008) and sprats (2010).
162. Annual variations of effort by method broadly reflect patterns shown by landings values (Diagram 14.34). The decline of beam trawlers values over the period is directly linked to a decrease in effort.
163. The seasonal distribution of landings values by species and method are shown in Diagram 14.35 and Diagram 14.36. The highest landings of beam trawled sole are recorded from October to April with a peak in January. Landings of plaice follow the
