SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Pandalus borealis

SPECIES NAME(s)

Northern prawn, northern shrimp

COMMON NAMES

cold water prawn, northern shrimp, deep-sea prawn, deepwater prawn, pink shrimp

 The single stock is exploited in the Barents Sea and in the Svalbard fishery protection zone (SFPZ) by the Norwegian and Russian fleet; other vessels (Greenland, Iceland and EU) are restricted to the SFPZ and “Loop Hole” (NAFO/ICES, 2011).


ANALYSIS

Strengths

Discarding is thought to be minimal, as the fishery is not catch regulated but presents bycatch restrictions as sorting grids and closures areas. Current biomass is well above Bmsy and fishing mortality is well below Fmsy.

Weaknesses

No management objectives have been established. Prey-predator relationships, important to stock dynamics, are poorly known.

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

1.STOCK STATUS

STOCK ASSESSMENT

Stock assessment is based on a Bayesian version of a surplus-production model that includes two survey indices and one commercial index; discards are not included. Uncertainties in the assessment are related to model insensitiveness to yearly changes and if rapid and large changes in recruitment happens; prey function of the Northern shrimp in the ecosystem especially by cod predation – that had recently increased (ICES, 2011b) – and alternative predators as capelin are still poorly known and may affect analysis (ICES, 2011a).

SCIENTIFIC ADVICE

ICES/NAFO analyzed the short-term risk scenarios for the stock and recommended that a TAC equal to or less than 60,000 tonnes be established for 2012, in order to ensure with a high probability, that F remains below Flim and B above Blim (ICES, 2011a).

Reference Points

The following reference points have been defined for the stock:

 TypeValueTechnical basis
Precautionary approachBlim0.330% of Bmsy ; relative value
 BpaNot defined 
 Flim1.71.7 of Fmsy ; relative value
TargetsNot definedNot defined 

Source : ICES (2011a)

Both biomass and fishing mortality for this stock are expressed as a ratio of their maximum sustainable yield value.

CURRENT STATUS

The stock is being sustainably harvested and in full reproductive capacity; is considered to be close to the carrying capacity (ICES/NAFO, 2011) and 2010 survey results demonstrated that the stock increased comparing with the last year (ICES, 2011c). As in previous years, stock biomass is above BMSY and fishing mortality below FMSY. Biomass is estimated to be well above Btrigger at the end of 2011 (ICES/NAFO, 2011). After a declining trend within 2004-2008, recruitment has been higher in 2009 and 2011 (ICES/NAFO, 2011).

Trends

Several countries joined Norway in the fishery since 1970s, contributing to a maximum of 128,000 tonnes in 1984. Catches have meanwhile varied within 21,000-61,000 tonnes, being around 75-93% of the total taken by the Norwegian fleet, with the rest by Russian, Icelandic, Greenlandic and EU vessels (NAFO/ICES, 2011). Since catches of 83,000 tonnes in 2000, values have been declining close to the lowest levels since the fishery developed, related to the reduced profitability of the fishery. Since 1995 the fleet has undergone major restructuring, existing nowadays fewer but larger and powerful factory trawlers (ICES, 2011a).

2.MANAGEMENT QUALITY

MANAGEMENT

Fishing is regulated through effort control, bycatch limits and a partial TAC only for the Russian zone. Fishing licenses are issued to Norwegian and Russian shrimp vessels; third countries’ vessels are limited to the Svalbard Fishery Protection Zone (SFPZ) and “Loop Hole”, and also through effort control (NAFO/ICES, 2011). Measures to limit bycatch include mandatory sorting grids and temporary area closures where high bycatch of fish juvenile or undersized shrimp (<15 mm) occurs. A minimum mesh size (stretched) of 35 mm is also enforced (ICES, 2011a).

Recovery Plans

Not applicable.

COMPLIANCE

Effort ceilings in the SFPZ only have been set so high as to not limit Russian and Norwegian effort but only restrict effort of third countries (ICES, 2008a). No overall TAC is set so fishers’ compliance is difficult to evaluate but catches are on a decreasing trend since 2000 due to reduced economic profitability (ICES, 2011a).

3.ENVIRONMENT AND BIODIVERSITY

BYCATCH
ETP Species

The marine mammals on Norway’s 2010 Red List include the right whale Balaena glacialis, bowhead whale Balaena mysticetus, blue whale Balaenoptera musculus, hooded seal Cystophora cristata, beluga whale Delphinapterus leucas, grey seal Halichoerus grypus, Sowerby’s beaked whale Mesoplodon bidens, narwhal Monodon monoceros, harbour seal Phoca vitulina, walrus Odobenus rosmarus (NBDI, 2011). No information could be found on possible interactions of these species with the fishery, in spite of Norway having initiated a programme to monitor marine mammal bycatch in 2004 (ICES, 2008b).

Similarly, no reports were found of interactions with seabirds on the Red List, which include the black guillemot Cepphus grille, Atlantic puffin Fratercula arctica, Leach’s storm-petrel Oceanodroma leucorhoa, black-legged kittiwake Rissa tridactyla, Brunnich’s guillemot Uria lomvia and the common guillemot Uria aalge (NBDI, 2011).

Other Species

Northern shrimp is the main prey of cod, but also important for several other fish and marine mammals; prey-predator relationship are yet poorly known (ICES, 2011a). Shrimp trawling is generally seen as the fishery type which generates the most discards of unwanted catch (Alverson et al., 1994). Bycatch in this fishery is specifically composed of small cod, haddock, Greenland halibut and redfish in the size range 5-25 cm (NIPAG, 2008). However, bycatch quantities are minimal as a result of mandatory sorting grids and temporary close areas with high bycatch (ICES, 2011a).

HABITAT

Increased bottom temperature and salinity have been registered in much of the Barents Sea in recent years, with possible consequences on both shrimp growth and the abundance of shrimp predators (NIPAG, 2008).

Benthic communities are particularly vulnerable to the impacts of bottom trawling, including sponges, anthozoans and corals as Lophelia pertusa(ICES, 2008b). Consequences of shrimp trawling on clay-silt bottoms were studied by Løkkeborg (2005) but are not clearly understood (ICES, 2011c).

Marine Reserves

A marine protected area network encompasses 36 sites and was implemented in Norway in 2008 (MFCA, 2009). Five cold-water coral reefs along the Norwegian coastline have been granted special protection status, with all towed fishing gears banned in the area (MFCA, 2006).The shrimp fishery is effort-regulated in the Svalbard Fishery Protection Zone since 1996 after concerns over the increasing size of the fleet (MFCA, 2008). Russia has not established yet a network of marine protected areas; Barents Sea is home to two of Russia’s federal Strictly Protected Reserves (zapovedniks), three Special Purpose Reserves and one other MPA, with five further Special Purpose Reserves currently proposed (Wood, 2007) although regulations on fishing are unclear.

DATA NOTES
  1. Both biomass and fishing mortality are determined relative to MSY estimates; scores are computed accordingly.
  2. The fishery is effort regulated so no TAC is set (partial TAC only for Russia zone), meaning management quality cannot be quantitatively scored.
