  • Summary Report on 2019 Residue Monitoring of Irish Farmed Fish & 2019 Border Inspection Post Fishery Product Testing undertaken at the Marine Institute

    Glynn, D.; McGovern, E.; Farragher, E.; Kelly, Corrine; Moffat, R.; Toomey, M. (Marine Institute, 2020)
    On behalf of the Department of Agriculture, Food and Marine (DAFM), the Marine Institute carries out monitoring of chemical residues in finfish for aquaculture sector. This monitoring is set out in the annual National Residue Control Plan, which is approved by the European Commission, and is an important component of the DAFM food safety controls and is implemented under a service contract with the Food Safety Authority of Ireland. Since 1999, the Marine Institute has implemented the National Residues Monitoring Programme for aquaculture. This is carried out on behalf of the Sea Fisheries Protection Authority, which is the responsible organisation for residue controls on farmed finfish. In 2019, in excess of 912 tests and a total of 2,601 measurements were carried out on 176 samples of farmed finfish for a range of residues. Implementation of the Aquaculture 2019 Plan involves taking samples at both farm and processing plant: *118 target samples taken at harvest: 105 farmed salmon and 13 freshwater trout. * 58 target samples were taken at other stages of production: 50 salmon smolts and 8 freshwater trout. All 2019 samples were compliant. For target sampling of farmed fish, a summary table of the residue results from 2005 - 2019 is outlined in Table 1. Overall, the outcome for aquaculture remains one of consistently low occurrence of residues in farmed finfish, with no non-compliant target residues results for the period 2006-2014, 0.11% and 0.10% non-compliant target residues results in 2015 and 2016 respectively and no non-compliant target results for the period 2017 to 2019.

    Marine Institute (Marine Institute, 2020)
    The Stock Book is the principal annual publication of the Marine Institute's Fisheries Ecosystems Advisory Services (FEAS). Its purpose is to provide the latest impartial scientific advice on the commercially exploited fish stocks of interest to Ireland. The Stock Book is used by the Department of Agriculture, Food and the Marine - (DAFM) at the Total Allowable Catch (TAC) negotiations with the EU in December and throughout the year at fisheries management meetings.
  • Western European Shelf Pelagic Acoustic Survey (WESPAS), 03 June – 12 July, 2020

    O'Donnell, Ciaran; O’Malley, M.; Smith, T.; O’Brien, S.; Mullins, E.; Connaughton, P.; Perez Tadeo, M.; Barile, C. (Marine Institute, 2020)
    The WESPAS survey program is the consolidation of two existing survey programs carried out by FEAS, the Malin Shelf herring acoustic survey, and the boarfish acoustic survey. The Malin Shelf herring acoustic survey has been carried out annually since 2008 and reports on the annual abundance of summer feeding aggregations of herring to the west of Scotland and the north and west of Ireland from 54°N to 58°30’N. The boarfish survey was conducted from 2011 using a chartered fishing vessel and reported the abundance of spawning aggregations of boarfish from 47°N to 57°N. In 2016 both surveys were combined into the WESPAS survey and have been carried out onboard the RV Celtic Explorer over a 42-day period, providing synoptic coverage of shelf waters from 47°30’N northwards to 58°30’N. Age stratified relative stock abundance estimates of boarfish, herring and horse mackerel within the survey area were calculated using acoustic data and biological data from trawl sampling. Stock estimates of boarfish and horse mackerel were submitted to the ICES assessment Working Group for Widely Distributed Stocks (WGWIDE) meeting in August 2020. Herring estimates are submitted to the Herring Assessment Working Group (HAWG) meeting in March every year. Survey performance will be reviewed at the ICES Planning Group meeting for International Pelagic Surveys (WGIPS) meeting in January 2021.
  • The “Smalls” Nephrops Grounds (FU22) 2020 UWTV Survey Report and catch scenarios for 2021

    Aristegui, M.; Blaszkowski, M.; Doyle, J.; Ryan, G.; McAuliffe, M (Marine Institute, 2020)
    This report provides the main results and findings of the fifteenth annual underwater television survey on the ‘Smalls grounds’ ICES assessment area; Functional Unit 22. The survey was multi-disciplinary in nature collecting UWTV and other ecosystem data. A total of 40 UWTV stations were surveyed successfully (high quality image data), carried out over an isometric grid at 4.5nmi or 8.3km intervals. The precision, with a CV of 8%, was well below the upper limit of 20% recommended by SGNEPS (ICES, 2012). The 2020 abundance estimate was 33% lower than in 2019 and at 750 million is below the MSY Btrigger reference point (990 million). Using the 2020 estimate of abundance and updated stock data implies catch in 2021 that correspond to the F ranges in the EU multi annual plan for Western Waters are between 1238 and 1560 tonnes (assuming that discard rates and fishery selection patterns do not change from the average of 2017–2019). One species of sea pens was recorded as present at the stations surveyed: Virgularia mirabilis. Trawl marks were observed at 48% of the stations surveyed.
  • The Labadie, Jones and Cockburn Banks Nephrops Grounds (FU2021) 2020 UWTV Survey Report and catch scenarios for 2021.

    Aristegui, M.; Tully, D.; Blaszkowski, M.; Doyle, J.; Fee, D.; O'Connor, S.; White, J. (Marine Institute, 2020)
    This report provides the main results of the 2020 underwater television survey on the ‘Labadie, Jones and Cockburn Banks’ ICES assessment area; Functional Unit 2021. The 2020 survey was multi-disciplinary in nature collecting UWTV, and other ecosystem data. A total of 97 UWTV stations were completed at 6nm intervals over a randomised isometric grid design. The mean burrow density was 0.102 burrows/m2 compared with 0.06 burrows/m2 in 2019. The 2020 geostatistical abundance estimate was 1020 million, a 65% increase on the abundance from 2019, with a CV of 5%, which is well below the upper limit of 20% recommended by SGNEPS 2012. Low to medium densities were observed throughout the ground. Using the 2020 estimate of abundance and updated stock data implies catch in 2021 that correspond to the F ranges in the EU multi annual plan for Western Waters are between 1682 and 1710 tonnes (assuming that discard rates and fishery selection patterns do not change from the average of 2017–2019). One species of sea-pen (Virgularia mirabilis) were recorded as present at the stations surveyed. Trawl marks were observed at 36% of the stations surveyed.
  • Aran, Galway Bay and Slyne Head Nephrops Grounds (FU17) 20 20 UWTV Survey Report and catch scenarios for 2021

    Doyle, J.; Galligan, S.; Aristegui, M.; O’ Brien, S.; Fitzgerald, R.; Tully, D.; McAuliffe, M (Marine Institute, 2020)
    This report provides the main results and findings of the nineteenth annual underwater television survey on the Aran, Galway Bay and Slyne head Nephrops grounds, ICES assessment area; Functional Unit 17. The survey was multi-disciplinary in nature collecting UWTV, CTD and other ecosystem data. In 2020 a total of 44 UWTV stations were successfully completed, 34 on the Aran Grounds, 5 on Galway Bay and 5 on Slyne Head patches. The mean burrow density observed in 2020, adjusted for edge effect, was medium at 0.29 burrows/m². The final krigged burrow abundance estimate for the Aran Grounds was 359 million burrows with a CV (Coefficient of Variance; relative standard error) of 4%. The final abundance estimate for Galway Bay was 27 million and for Slyne Head was 7 million, with CVs of 13% and 4% respectively. The total abundance estimates have fluctuated considerably over the time series. The 2020 combined abundance estimate (394 million burrows) is 20% lower than in 2019, and it is below the MSY Btrigger reference point (540 million burrows). Using the 2020 estimate of abundance and updated stock data implies catches between 443 and 508 tonnes in 2021 that correspond to the F ranges in the EU multi annual plan for Western Waters, assuming that discard rates and fishery selection patterns do not change from the average of 2017–2019. Virgularia mirabilis was the only sea-pen species observed on the UWTV footage. Trawl marks were present at 7% of the Aran stations surveyed.
  • Porcupine Bank Nephrops Grounds (FU16) 2020 UWTV Survey Report and catch scenarios for 2021

    Aristegui, M.; Blaszkowski, M.; Doyle, J.; Hehir, I.; Lynch, D.; Ryan, G.; Lordan, C. (Marine Institute, 2020)
    This report provides the results of the eighth underwater television on the ‘Porcupine Bank Nephrops grounds’ ICES assessment area; Functional Unit 16. The survey was multi-disciplinary in nature collecting UWTV and other ecosystem data. In total 65 UWTV stations were successfully completed in a randomised 6 nautical mile isometric grid covering the full spatial extent of the stock. The mean burrow density observed in 2020, adjusted for edge effect, was 0.17 burrows/m². The final krigged abundance estimate was 1264 million burrows with a CV of 4% and an estimated stock area of 7,130 km2. The 2020 abundance estimate was 25% higher than in 2019. Using the 2020 estimate of abundance and updated stock data implies catches between 2653 and 3290 tonnes in 2021 that correspond to the F ranges in the EU multiannual plan for Western Waters (assuming that all catch is landed). Four species of sea-pen; Virgularia mirabilis, Funiculina quadrangularis, Pennatula phosphorea and the deepwater sea-pen Kophobelemnon stelliferum were observed during the survey. Trawl marks were also observed on 22% of the stations surveyed.
  • FU19 Nephrops g rounds 20 20 UWTV s urvey r eport and catch scenarios for 2021

    Aristegui, M.; Doyle, J.; O’ Brien, S.; Tully, D.; McAuliffe, M; Fitzgerald, R.; Fee, D.; O'Connor, S.; Galligan, S.; Blaszkowski, M.; et al. (Marine Institute, 2020)
    This report provides the main results of the eleventh underwater television survey of the various Nephrops patches in Functional Unit 19. The survey was multi-disciplinary in nature collecting UWTV, multi-beam and other ecosystem data. In 2020 a total 42 UWTV stations were successfully completed. The mean density estimates varied considerably across the different patches. The 2020 raised abundance estimate was a 20% decrease from the 2019 estimate and at 320 million burrows is below the MSY Btrigger reference point (430 million). Using the 2020 estimate of abundance and updated stock data implies catch in 2021 that correspond to the F ranges in the EU multi annual plan for Western Waters are between 531 and 595 tonnes (assuming that discard rates and fishery selection patterns do not change from the average of 2017–2019). Two species of sea pen were observed; Virgularia mirabilis and Pennatula phosphorea which have been observed on previous surveys of FU19. Trawl marks were observed at 26% of the stations surveyed.
  • Cruise report: Irish Anglerfish & Megrim Survey 2020

    Kelly, Eoghan; Gerritsen, Hans D; Coleman, Paul; Stokes, David; O’ Brien, S.; White, Jonathan; Aristegui, M.; O’Connor, Sean (Marine Institute, 2020)
    The 2020 Irish Anglerfish and Megrim Survey (IAMS) took place from 23rd February to 18th March (area 7bcjk) and 12-21st April 2020 (area 6a) on RV Celtic Explorer. The main objective of the survey is to obtain biomass and abundance indices for anglerfish (Lophius piscatorius and L. budegassa) and megrim (Lepidorhombus whiffiagonis and L. boscii) in areas 6a (south of 58°N) and 7 (west of 8°W). Secondary objectives are to collect data on the distribution, relative abundance and biology of other commercially exploited species. For the second year, additional sampling took place in deep water (up to 1,500m) in order to monitor the recovery of exploited deep-water species following the decline of the deep-water fisheries in Irish waters. The IAMS survey is coordinated with the Scottish Anglerfish and Megrim Survey (SIAMISS) and uses the same gear and fishing practices.
  • INFOMAR Marine Mapping Study. Options Appraisal Report: Final Report 30 June 2008

    Price Waterhouse Coopers (Marine Institute, 2008)
    The Integrated Mapping for the Sustainable Development of Ireland’s Marine Resource (INFOMAR) programme is Ireland’s national marine mapping programme. It is the successor to the Irish National Seabed Survey (INSS), and is a joint venture of the Geological Survey of Ireland (GSI) and the Marine Institute (MI). The focus of the INFOMAR programme is to create a range of integrated mapping products of the physical, chemical and biological features of the seabed, in the near-shore (Zone 1, 0m to 50m) area and building on previous INSS offshore survey area (Zone II, 50m to 200m), to complete the mapping programme for the entirety of Ireland’s off-shore waters. Against this background, and to fulfil the NDP Value For Money reporting requirements for Large Capital Projects (>€30 million), PricewaterhouseCoopers (PwC) were commissioned by the Department of Communications, Energy and National Resources (DCENR) to undertake a detailed appraisal of the INFOMAR project. The methodology for undertaking the appraisal involved both primary and secondary research, including extensive consultation with stakeholders of the INFOMAR. A range of options for the INFOMAR programme were identified and appraised in financial and qualitative terms and are presented within this report.
