Conservation Credits rewards can be earned using more selective gear to reduce the mortality of roundfish in the Scottish Nephrops fisheries. During trials to measure the selectivity of square mesh panels (SMPs) of 110 and 120mm in 80mm codends , four different 3m long SMP configurations were tested with an 80mm diamond mesh codend; three in 110mm mesh size and one in 120mm mesh size. The panels were positioned at 15 -18m from the codline, and were rigged in the taper or straight extension of the net; a total of 30 valid hauls were completed. Of the test cases in these trials the best option for haddock and whiting selectivity was the 110mm panel in the straight extension. The 120mm panel in the tapered section of the net had similar selective properties, whilst the 110mm panel in the taper had comparatively poor selection. The main problem with the 110mm panel in the straight extension was the relatively poor ability of small haddock and whiting to escape. This was particularly true for haddock, whose ability to escape through the SMP may have been affected by poor condition soon after spawning.
