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 shrimp trawling was most merciful of the three trawl types, by far receiving the lowest rigged 18 fathom Nephrops trawl set up, using a triple warp and centre clump arrangement. Three hinged rectangular rigid sorting grids (1.25 X 0.7 m) mounted in separate nets were tested during the trial: Two identical Nephrops sorting grids (NSG1 and NSG2) with vertical bars spaced 15 mm apart in the lower half, an escape 1999-08-01 · The trawl design used was a 544 × 110 mm TV-trawl, a combined fish and Nephrops trawl, often used in the North Sea Nephrops fishery when fish by-catches are important. Fishing height was about 4 m and wing-end spread about 23 m, two identical trawls were used in a three towing warp twin trawl system. 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 2019-02-01 · Nephrops, whiting, lesser-spotted catshark, and haddock were the main species encountered during the trial ().Total whiting catches (kg) were lower in the test compared with the control trawl, with relatively small differences in catches for the other main species.

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.

The Echo developed by Notus, initially for catching shrimp, has proved to be a game changer for trawlers fishing for nephrops as the original technology has been adapted so that skippers can see Initially the operation will involve carrying out five standard sledge tows on known Nephrops grounds, 500m apart in a linear path at both of the trawl sites. Following the sledge work the trawl will deployed over the areas previously surveyed by the sledge.
