Nephrops are known to move relatively passively along the bottom sheet of the trawl (Catchpole and Revill, 2008), and the more contact they have with larger mesh, the more likely they are to

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. The Nephrops trawling efforts caught by-catches consisting of the highest individual abundance and biomass, these efforts also received the highest proportion of non-commercial invertebrate by-catch compared to their target catch.

The Nephrops trawling efforts caught by-catches consisting of the highest individual abundance and biomass, these efforts also received the highest proportion of non-commercial invertebrate by-catch compared to their target catch. The shrimp trawling was most merciful of the three trawl types, by far receiving the lowest
