Figure 5.4 – The relationship between targeted catch size (tonnes) and the position (metres) of the CCU relative to the forward edge of the cod-end. Multiple linear regression analysis determined that catch size increased significantly the further aft the catch limitation releaser was positioned on the cod-end (t = 5.41; p < 0.001), while there was no significant difference between the relationships for either cruise (t = -0.40; p = 0.699). Blue dots show results from cruise 1 and red dots cruise 2. Open circles show hauls where problems with the releasers were experienced and are not included in the regression analysis.
