Although currently at a sustainable level, fishing pressure on this stock has been high and the biomass currently too low.
Trawl fisheries for scampi (Nephrops) are associated with large quantities of bycatch, including overfished species such as cod and juvenile fish. The fishery also takes considerable bycatch of other species such as haddock, cod, monkfish, megrim and hake. Increase the sustainability of the scampi you eat by choosing pot or creel caught rather than trawled scampi. If choosing trawled fish ask for Nephrops trawled in nets using separator grids and larger meshes (80 mm is the mesh size in general use) to increase their selectivity and reduce bycatch and discards.
To ensure exploitation is in line with the size of the local population ,and so better protect the stock, scientists advise that management should be implemented at the functional unit (FU) level. Currently there is no localized management of stocks which has resulted in the overfishing and depletion of some Nephrops populations like the Farn Deeps.
Norway Lobster (also known as langoustine or scampi) live in burrows on the seabed. They are limited to a muddy habitat and require sediment with a silt and clay content to excavate burrows. Their distribution therefore is determined by the availability of suitable habitat. They occur over a wide area in the North East Atlantic, from Iceland to North Africa and into the Mediterranean, and constitute a valuable fishery for many countries. Males grow relatively quickly to around 6 cm, but seldom exceed 10 years old. Females grow more slowly and can reach 20 years old. Females mature at about 3 years. In the autumn they lay eggs which remain attached to the tail for 9 months (known as being "berried"). During this time the berried females rarely emerge from their burrows and therefore do not commonly appear in trawl catches, although they may be caught using baited creels. This habit of remaining in their burrows has probably afforded their populations some resilience to fishing pressure. Egg hatching occurs in the spring, and females emerge in spring/summer to moult and mate.
Celtic Sea and West of Scotland
Nephrops stock assessment and management is based on a system of management units (A-R), which broadly coincide with ICES areas, and functional units (FU)(1-33), which cover the distribution of the species, particularly in relation to suitable habitat types. In part due to the difficulty of assessing stocks, which may spend significant amounts of time in burrows, a fishery independent survey method using video surveys has been developed, which uses burrow density to estimate stock biomass. This technique is now widely, though not comprehensively, used within the management units, enabling recommended TACs and management advice to be provided by ICES. Fisheries landings data are also available to augment the video survey data.
The abundance shows an overall decreasing trend over time and is currently below MSY Btrigger. The harvest rate, calculated as (landings + dead discards)/(abundance estimate), has been well above the FMSY recently but declined well below FMSY in 2015.
ICES advises that when the MSY approach is applied, and assuming that discard rates and fishery selection patterns do not change from the average of 2013-2015, catches in 2017 should be no more than 489 tonnes. This implies landings of no more than 456 tonnes.
No specific management objectives are known to ICES. As part of the plan to recover cod in areas where it is depleted (North and Irish Seas, West of Scotland and Kattegat ) a Cod Recovery Zone (CRZ) has been established. In this zone effort restrictions have been introduced for the protection of cod i.e. a fishing boat will be restricted as to how much time it spends at sea fishing. The Nephrops fishery in this area is heavily influenced by these effort restrictions. Derogations or exemptions from compliance with effort restrictions in the form of more days fishing at sea are available to trawlers using species-selective devices suchs as grids to reduce cod by-catch. Vessels may also receive an additional allocation of days (buy backs) where they agree to fish exclusively using specified selective gear e.g. NetGrid. In the Irish Sea for example fishing vessels using Nephrop's trawls will receive extra days if using a SELTRA 300; SELTRA 270; Faithlie panel or a Flip-Flap trawl etc. Quota may also be allocated according to what gear type is in use. For example in Sweden 30% is allocated to creels, 50% to grid trawls and the remaining 20% to other trawls. To protect the Nephrops stock in this management area, ICES advises that management should be implemented at the functional unit level.
The fisheries in this area are mainly otter trawl fisheries using single and twin-rigs and cod end mesh size of 70-99 mm. The minimum landing size for nephrops in EU waters is 20-25mm (40mm Skagerrak/Kattegat) total carapace (body) length, depending on area of capture. The MLS is 25 mmCL for this area. Nephrops fisheries in this area also have catches of hake, megrim, and monkfish. As of 2012, all EU, Faroese and Norwegian vessels which exceed 12m overall length must be fitted with a Vessel Monitoring System (VMS), a form of satellite tracking using transmitters on board fishing vessels to monitor fishing activity. The system is a legal requirement under EC Regulation 2244/2003 and Scottish Statutory Instrument (SI) 392/2004.
