The fishing vessel *Imogen 3* PZ 110 was chartered to undertake the trials in the South West of England otter trawl fishery in August and September 2018. Eleven days of fishing trials were conducted in ICES area VIIE, statistical rectangles 28E3 and 28E4, with a total of 27 hauls completed, 25 of these were considered valid for examination. The specific objective of this trial was to investigate the operation and profitability of a semi‐pelagic trawl towed higher in the water column to catch non‐quota species. It was thought that John Dory (*Zeus faber*), Hake (*Merluccius merluccius*), Black Seabream (*Spondyliosoma cantharus*), Cuttlefish ( *Sepia officinalis*) and Squid (*Loligo forbesi *& *Loligo vulgaris*) could be caught in greater quantities than when using a demersal trawl.

A demersal trawl was used for 13 tows (52 hours 50 minutes), whilst 12 tows (45 hours 35 minutes) considered valid were made using the semi‐pelagic trawl. It was observed that it was possible to operate the semi pelagic rig from a conventional demersal trawler, but for maximum efficiency modifications to the hydraulic systems would be necessary.
