ICES. In many situations by reducing the bulk of fish entering the trawl there is a noticeable increase in the quality and quantity (7 – 10%) of nephrops retained in the trawl.

35 Nephrops (Adey, 2007), 95% of total European landings are taken by demersal trawlers (Briggs, 36 2010; Ungfors et al., 2013). Catching Nephrops efficiently with trawls requires using relatively 37 small mesh codends (Krag et al., 2008; Frandsen et al., 2010), which can lead to large bycatches Employment was around 510, on a full time equivalent basis, on-board trawl vessels in the West of Scotland, generating gross value added of around £12 million and landing 8,500 tonnes of Nephrops. In the North Sea, there were insufficient creel vessels with a great enough dependency on Nephrops to be modelled as individual fleet segments without breaching data disclosure thresholds.
