SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Gadus morhua

SPECIES NAME(s)

Atlantic cod

COMMON NAMES

Atlantic cod

 According with tagging and genetic studies, it has been strongly suggested that Atlantic cod in the north Atlantic is sub-structured. The research of cod stock structure in Norwegian and Icelandic waters, and in the northwest Atlantic revealed considerable genetic differentiation between populations at localized scale (Imsland and Jónsdóttir 2003).

RETAILERS & SUPPLY CHAIN
  • This profile is not currently high on our priority list for development, and we can’t at this time provide an accurate prediction of when it will be developed. To speed up an evaluation of the sustainability status of lower priority fisheries we have initiated a program whereby industry can directly contract SFP-approved analysts to develop a FishSource profile on a fishery.

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
Faroe Islands
Bottom trawls

Last updated on 12 September 2008

No analytical assessment of this stock has been carried out. No information other than official landings. The stock definition is uncertain. Cod in this area may in fact be migrants from other areas and therefore may not constitute a separate stock from that in Division VIa (West of Scotland).

CURRENT STATUS
Faroe Islands
Bottom trawls

Last updated on 25 October 2011

There is no information of the status of Rockall cod. However, the official landings data show a substantial declining trend in landings from nearly 2,000 tonnes in 1985 to around 60 tonnes during the period from 2005 to 2007. In 2008, official landings are in the order of 90 tonnes (ICES, 2009a).

Trends

Last updated on 25 Oct 2011

The only information available is official landings data. This data show a serious and substantial declining trend in landings to the lowest in the time series (circa 100 tonnes) in most recent years. The highest catch (1,973 tonnes) was reached in 1985. After that the catch declined gradually down to 62 tonnes in 2007 and in 2008 increased slightly to 93 tonnes (ICES, 2009a). The fishery is dominated by Ireland, Norway and UK.

2.MANAGEMENT QUALITY

MANAGEMENT
Faroe Islands
Bottom trawls

Last updated on 12 September 2008

There are no explicit management objectives or plans for this stock. There is also lack of effort restriction by the managers in this area. The 2006 and 2007 TACs for cod in ICES areas Vb (Faroe Islands, EC waters), VI (West of Scotland and Rockall), XII and XIV (Greenland) were 490 t and 402 t respectively. The minimum landing size of cod in the human consumption fishery in this area is 35 cm (ICES, 2008).

COMPLIANCE
Faroe Islands

Last updated on 25 October 2011

Compliance cannot be assessed since there is no set TAC available for Rockall cod. Misreporting and under-reporting are considered to be a problem in this fishery.

3.ENVIRONMENT AND BIODIVERSITY

BYCATCH
ETP Species
Faroe Islands
Bottom trawls

Last updated on 22 March 2009

This ecoregion harbours extensive populations of grey and common seals are increasing in abundance. It is not known what effect this increase has on local fish populations, however recent studies of seal diets off western Scotland revealed that grey seals may be an important predator for cod, herring and sandeels in this area.

Other Species
Faroe Islands
Bottom trawls

Last updated on 25 October 2011

The demersal fisheries in Division VIb (Rockall) are predominantly conducted by otter trawlers fishing for cod, haddock, saithe, megrim and whiting (ICES, 2009b), with bycatches of saithe, megrim, and lemon sole. Cod is a minor bycatch in the limited Irish fishery targeting mainly haddock and megrim. Cod also can be important bycatches of other species, notably saithe and anglerfish in the deeper water and of Nephrops on the more inshore Nephrops grounds.

HABITAT
Faroe Islands
Bottom trawls

Last updated on 12 September 2008

In otter trawling a large net, is dragged along the bottom or up in the water column behind a towing vessel. Depending on the fishery and the size of the vessel being used, otter trawls can have mouths ranging from thirty feet or so across up to hundreds of feet. The towed demersal gear comes into contact with the seabed, and almost certainly disturbs the sub-surface sediment layers. This may have physico-chemical and biological implications likely to affect the ecosystem. However, effects on the benthic habitat in Rockall area as a result of demersal gears used in the cod fisheries have not yet fully been understood. Fisheries on the Rockall Bank are considered as a threat to the sensitive bottom fauna such as the cold-water corals (ICES, 2009b).

Marine Reserves

Last updated on 12 Sep 2008

At the 25th Annual Meeting of NEAFC (in November 2006), a closure of three areas on the Rockall Bank to bottom fishery was proposed to protect cold-water corals: North West Rockall, Logachev Mounds and West Rockall Mounds (NEAFC AM 2006). This measure is in force for the period 1 January 2007–31 December 2009. At the 26th Annual Meeting of NEAFC (in November 2007), a new closed area (Empress of British Banks) was established, and the boundaries of the North West Rockall closure were slightly modified. Due to the complex shape of the boundaries of the North West Rockall closure proposed by ICES, which potentially could cause problems with enforcement, the introduced changes differed from the ICES recommendation. NEAFC also requested ICES to continue providing all available new information on distribution of vulnerable habitats in the NEAFC Convention Area and fisheries activities in and in the vicinity of such habitats.
