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. In Sweden, the majority of Nephrops (Norway lobster, Nephrops norvegicus L.) are fished using bottom trawls.
Crustacean trawlers are part of an industrial fleet that, besides Nephrops, targets deep water shrimps. Creels are used by a multi-gear, multi-target artisanal
With a twin trawl the selectivity ofNephrops in the Nephrops trawl used in Sweden today (70 mm codend mesh size) was investigated. Selectivity parameters are presented. More than half of the number ofNephrops were undersized in this trawl. In addition any difference in selection range

Certification status: Fishery Nephrops Trawls - Otter trawls 27 (Atlantic, Northeast) All nephrops trawls are made with small mesh netting to retain the relatively small nephrops, this can result in considerable bycatch of juvenile fish in some areas.
The Flip-Flap trawl comprises a trawl with large mesh sections to provide for whitefish escape along with a flexible grid that is intended to create a physical barrier to whitefish, especially cod, whilst allowing the passage of Nephrops through to the cod end. 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. 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

Note that no estimates of Nephrops trawl fishery using a modified Nephrops trawl incorporating 200mm bobbins and a 200mm square mesh panel. Catches of Nephrops and monkfish remained consistent with that of a standard commercial Nephrops trawl. There were significant reductions in relative catch rates of cod and larger haddock (>25cm) and whiting (>28cm). Nephrops trawl fisheries are diverse in nature with a variety of trawl configurations utilised and species targeted, and it is unlikely that any one potential solution will work in all cases.
