During 2008 experiments were conducted to improve the selectivity of round-fish from gears used by Scottish Nephrops trawlers targeting North Sea grounds. The main aims of these selectivity trials were to assess the differences in performance between square mesh panels (SMPs) placed in the straight extension or in the taper, between 110 and 120 mm SMPs, and between gears towed by vessels of different horsepower. Results demonstrated that compared to an 80 mm codend with no SMP, all cases with an SMP improved the selection of haddock and whiting. Increasing the mesh size of the SMP from 110 mm to 120 mm in the straight extension of the net rather than the tapered section improved the selection of whiting and was sometimes shown to improve the selection of haddock. Catches of haddock or whiting were not affected by the power of the vessel. Goals: (1) To assess the differences in performance by placing a square mesh panel (SMP) in either the tapered or straight section of a Scottish commercial Nephrops trawl; (2) To compare the performance of 110mm SMP against a 120mm SMP; (3) To assess if SMP's are more selective on low-powered vessels compared to high-powered vessels.
