Once inside the trawl, Nephrops pass along the bottom of the net and seldom rise above the selvedges (Main and Sangster 1985a). The average swimming height rarely exceeds 0.5 m (maximum 1 m) (Briggs and Robertson 1993). Time and weather permitting, trawling may take place and all Nephrops caught during the trawls will be assessed for morphometric, weight, maturity and sex data. All landed litter will be recorded and returned to port.

27 (Atlantic, Northeast) Tonnage. 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. This unwanted bycatch can be reduced by using various selective devices such as square mesh panels and larger diamond mesh to … Time and weather permitting, trawling may take place and all Nephrops caught during the trawls will be assessed for morphometric, weight, maturity and sex data.

0.5 m s 1, and because trawl towing speeds are faster (*1.3 m s 1 or 2.5 knots), Nephrops are quickly over-taken by the trawl (Newland 1989). Once inside the trawl, Nephrops pass along the bottom of the net and seldom rise above the selvedges (Main and Sangster 1985a). The average swimming height rarely exceeds 0.5 m (maximum 1 m) (Briggs and Robertson 1993).

Key Findings. The research shows that in 2017 employment on Nephrops creel vessels in the West of Scotland was around 210 on a full time equivalent basis, generating gross value added of around £5 million and landing 1,300 tonnes of Nephrops.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

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).
