1 The 2009 quota year was used as the control period rather than the 2010 quota year as the Catch Quota scheme trial was undertaken in the 2010 quota year.
3 This pre-existing difference in operational scale between participating and non-participating vessels raises the possibility that there are substantive differences between the two groups above and beyond their participation in the trial and which may also affect the results. This suggests that a cautionary approach is taken in interpreting the results and in attributing impacts to the FDF trial alone.
5 Operating profit is comprised of revenues less operating costs. Operating costs comprise the variable and fixed costs directly associated with fishing activity; crew share, fuel, gear and maintenance costs etc. Operating costs do not include financing costs (eg loan repayments) or asset depreciation.
6 Vessels are categorised into segments according to, for example, activity, location, gear type, vessel power
7 Participating skippers were asked how much cod quota they had leased in during 2011. 13 responded to the question giving a total figure of 1,457 tonnes. Assuming this was all North Sea cod quota, it represents around 13 per cent of the total. This is a substantial proportion, but without evidence on the baseline figure (ie how much they would have leased in the absence of the FDF trial) or whether they used the quota or resold it, it is difficult to interpret.
