  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">Following experimental work carried out in 2013, a twin-rig trawler, the 
Ilfracombe-based *Our Olivia Belle *(BD 277), was chartered to undertake 
further trials of a modified demersal trawl in August 2014 to look at 
selectivity in a mixed demersal fishery off south-west Cornwall. The primary 
aim was to improve the selectivity of the trawl to reduce discards of unwanted 
haddock with the least possible impact on the wanted catches of haddock and 
other commercial species. This is important in view of the future 
implementation of the landings obligation and associated catch quotas for 
species such as haddock. Following discussions with several Newlyn-based 
trawler operators, the decision was taken to investigate the effect of 
inserting square-mesh panels (SQMP) of 155 mm mesh into the top panel of the 
lengthener of an otter trawl. A twin-rig trawl, deployed as for normal haddock 
fishing, was used to compare the catches of modified and standard trawl nets 
in a series of tows on the fishing grounds off SW Cornwall.</dc:description>
