  • Cod Fact Sheet
    R FACT SHEET Cod (Gadus morhua) Image taken from (Cohen et al. 1990) Introduction Cod (Gadus morhua) is generally considered a demersal fish although its habitat may become pelagic under certain hydrographic conditions, when feeding or spawning. It is widely distributed throughout the north Atlantic and Arctic regions in a variety of habitats from shoreline to continental shelf, in depths to 600m (Cohen et al. 1990). The Irish Sea stock spawns at two main sites in the western and eastern Irish Sea during February to April (Armstrong et al. 2011). Historically the stock has been commercially important, however in the last decade a decline in SSB and reduced productivity of the stock have led to reduce landings. Reviewed distribution map for Gadus morhua (Atlantic cod), with modelled year 2100 native range map based on IPCC A2 emissions scenario. www.aquamaps.org, version of Aug. 2013. Web. Accessed 28 Jan. 2011 Life history overview Adults are usually found in deeper, colder waters. During the day they form schools and swim about 30-80 m above the bottom, dispersing at night to feed (Cohen et al. 1990; ICES 2005). They are omnivorous; feeding at dawn or dusk on invertebrates and fish, including their own young (Cohen et al. 1990). Adults migrate between spawning, feeding and overwintering areas, mostly within the boundaries of the respective stocks. Large migrations are rare occurrences, although there is evidence for limited seasonal migrations into neighbouring regions, most Irish Sea fish will stay within their management area (ICES 2012). Historical tagging studies indicated spawning site fidelity but with varying degrees of mixing of cod between the Irish Sea, Celtic Sea and west of Scotland/north of Ireland (ICES 2015).

  • 1. a Plankton Highway Along the Western Coasts of the UK
    HABs themselves should not be used as indicator 1. A plankton highway along of water quality. the western coasts of the UK Main policy implications This work has demonstrated that the stratified regions around the western coasts of the UK and Ireland have particular unique properties and constitute distinct eco-hydrodynamic regions. Such oceanographic regionality is directly relevant to a range of aspects likely to be considered in the Marine Bill, especially Marine Spatial Planning (http://www.defra.gov.uk/corporate/consult/marine bill/index.htm). Use of such knowledge is fundamental to the characterisation (‘typology’) of UK shelf waters (relevant to the proposed European Marine Strategy Directive), and increasing awareness is required of these oceanographic complexities with regard to, for example, the consideration of indicators of ecosystem status (Tett et al., 2004a, b; Larcombe et al. 2004), fisheries management and marine nature conservation. In summer, the density-driven flows at the boundaries of the stratified regions cause a major regional flow, which acts to limit transport between neighbouring eco-hydrodynamic regions. For example, summer transport between the Celtic Sea and the Irish Sea is very limited, while there is strong transport along their boundary (St Georges Channel). There is thus limited potential for transport of plankton across these pathways, Figure 1.1. The combined pathway from the results of three but high potential for transport along them, as field programs, with drifter tracks overlain on the contours of indicated by the occurrence of Karenia mikimotoi bottom density field. along this pathway (Raine, 1993).

  • Celtic Seas Ecoregion – Ecosystem Overview
    ICES Ecosystem Overviews Celtic Seas Ecoregion Published 14 December 2018 https://doi.org/ 10.17895/ices.pub.4667 7.1 Celtic Seas Ecoregion – Ecosystem overview Ecoregion description The Celtic Seas ecoregion covers the northwestern shelf seas of the EU. It includes areas of the deeper eastern Atlantic Ocean and coastal seas that are heavily influenced by oceanic inputs. The ecoregion ranges from north of Shetland to Brittany in the south. Three key areas constitute this ecoregion: • the Malin shelf; • the Celtic Sea and west of Ireland; • the Irish Sea. The Celtic Seas ecoregion includes all or parts of the Exclusive Economic Zones (EEZs) of three EU Member States. Fisheries in the Celtic Seas are managed through the EU Common Fisheries Policy (CFP), with fisheries of some stocks managed by the North East Atlantic Fisheries Commission (NEAFC) and by coastal state agreements. Responsibility for salmon fisheries is taken by the North Atlantic Salmon Conservation Organization (NASCO) and for large pelagic fish by the International Commission for the Conservation of Atlantic Tunas (ICCAT). Collective fisheries advice is provided by the International Council for the Exploration of the Sea (ICES), the European Commission’s Scientific Technical and Economic Committee for Fisheries (STECF), and the North Western Waters and Pelagic ACs. Environmental policy is managed by national governments and agencies and by OSPAR; advice is provided by national agencies, OSPAR, the European Environment Agency (EEA), and ICES. International shipping is managed under the International Maritime Organization (IMO). Figure 1 The Celtic Seas ecoregion, showing EEZs, larger offshore Natura 2000 sites, and operational and authorized wind farms.

  • Haddock (Melanogrammus Aeglefinus) in Divisions 7.B–K (Southern Celtic Seas and English Channel)
    ICES Advice on fishing opportunities, catch, and effort Celtic Seas, Greater North Sea, and Oceanic Northeast Atlantic ecoregions Published 28 June 2019 Haddock (Melanogrammus aeglefinus) in divisions 7.b–k (southern Celtic Seas and English Channel) ICES advice on fishing opportunities ICES advises that when the EU multiannual plan (MAP) for Western waters and adjacent waters is applied, catches in 2020 that correspond to the F ranges in the MAP are between 11 418 and 23 262 tonnes. According to the MAP, catches higher than those corresponding to FMSY (16 671 tonnes) can only be taken under conditions specified in the MAP, while the entire range is considered precautionary when applying the ICES advice rule. Stock development over time Spawning–stock biomass (SSB) has declined since 2011 and remains above MSY Btrigger in 2019. Fishing mortality (F) has been above FMSY for the entire time series. Recruitment in 2018 was estimated to be the second highest in the time-series. Figure 1 Haddock in divisions 7.b–k. Summary of the stock assessment. The assumed 2019 recruitment value is unshaded. Shaded areas in F and SSB plots and error bars in the recruitment plot represent 95% confidence intervals. Uncertainty boundaries are not available for 2019. Stock and exploitation status ICES assesses that fishing pressure on the stock is above FMSY, but below Fpa and Flim, and that the spawning–stock size is above MSY Btrigger, Bpa and Blim. ICES Advice 2019– had.27.7b – https://doi.org/10.17895/ices.advice.4785 ICES advice, as adopted by its Advisory Committee (ACOM), is developed upon request by ICES clients (European Union, NASCO, NEAFC, and Norway).
