The reported sea trials are part of the FISP funded CodSELect project. Apart from the current trials, the project involves a number of controlled laboratory tank trials conducted in the Marine Directorate’s facilities in the Marine Laboratory in Aberdeen as well as sea trials on board the Marine Directorate’s research vessel Alba Na Mara. The trials took place on FV Westro PD20, between 3-9 October 2023, in Neprhops commercial grounds (NE Piper). The data collection was carried out by both Marine Directorate and Scottish Fishermen’s Federation scientific personnel. The objective was to investigate whether artificial light can influence fish behaviour, with main focus on cod, and enhance escape through a square mesh panel (SMP) on the top panel of a SELTRA sorting box in the extension of a commercial trawl.
