    • Celtic Sea Herring Acoustic Survey Cruise Report 2021, 08 - 28 October 2021

      O'Donnell, Ciaran; Mullins, Eugene; Daly, E.; Keogh, Niall; Collins, John (Marine Institute, 2021)
      In the southwest of Ireland and the Celtic Sea (ICES Divisions VIIaS, g & j), herring are an important commercial species to the pelagic and polyvalent fleet. For a period in the 1970s and1980s, larval surveys were conducted for herring in this area. However, since 1989, acoustic surveys have been carried out, and currently are the only tuning indices available for this stock. In the Celtic Sea and VIIj, herring acoustic surveys have been carried out since 1989. Since 2004 the survey has been fixed in October and carried out onboard the RV Celtic Explorer. The geographical confines of the annual 21 day survey have been modified in recent years to include areas to the south of the main winter spawning grounds in an effort to identify the whereabouts of winter spawning fish before the annual inshore spawning migration. Spatial resolution of acoustic transects has been increased over the entire south coast survey area. The acoustic component of the survey has been further complemented since 2004 by detailed hydrographic, marine mammal and seabird surveys. Survey design and geographical coverage have been modified over the time series to adapt to changes in stock size and behaviour. Since 2016, the wider core distribution area has been surveyed by means of two independent surveys and supplemented with small high resolution adaptive surveys focusing on areas of high abundance.
    • CV20_02 INFOMAR Survey Report

      Sheehan, Kevin; INFOMAR Survey Team (Marine Institute, 2021-11-04)
      Geological Survey Ireland (GSI) and Marine Institute (MI) conducted seabed mapping between 2003 and 2005 under the auspices of the Irish National Seabed Survey (INSS) and this continued from 2006 to present day under the INtegrated mapping FOr the sustainable development of Irelands MArine Resource (INFOMAR) programme. INSS was one of the largest marine mapping programmes ever undertaken globally, with a focus on deep water mapping. INFOMAR is a joint venture between the GSI and the MI and is funded by the Irish Government through the Department of Communications, Climate Action and Environment (DCCAE). INFOMAR Phase 1, 2006 to 2015 focused on mapping 26 priority bays and 3 priority areas around Ireland and creating a range of integrated mapping products of the physical, chemical and biological features of the seabed in those areas. INFOMAR Phase 2, 2016 to 2026 intends to map the remainder of Ireland’s entire seabed. Figure 1 shows the extent of the continental shelf mapped area under INSS and INFOMAR and the outstanding areas as of January 2019. Grey have already been mapped, blue, white and coloured hatched areas are unmapped. As of 2018 the remaining survey area has been split at the 30 nautical mile limit (Nm). The inshore survey fleet, managed by GSI is responsible for mapping inshore of the 30Nm limit and the MI vessels are responsible for mapping the offshore. Survey areas are defined into gridded survey units known as INFOMAR Survey Units (ISUs). ISUs are all 1000 km2 in size and are uniquely identifiable by a letter on the x axis and number on the y axis. Each ISU is coloured in a shade of blue which indicates the modal water depth in that ISU. Colour scales are used, to denote the three depth bands; 50 to 100m, 100 to 150m and 150m plus.
    • Summary Report on 2020 Residue Monitoring of Irish Farmed Finfish & 2020 Border Inspection Post Fishery Product Testing undertaken at the Marine Institute

      Glynn, Denise; McGovern, Evin; Farragher, E.; Kelly, Corinne; Moffat, R.; Kaur, Navdeep; Toomey, M. (Marine Institute, 2021)
      As with other farmed animals, farmed finfish can be subject to disease and infestation which can have animal welfare, environmental and commercial implications. Therefore, authorised veterinary medicines and treatments may be used, and sometimes must be used, to control disease and infestation as part of health control plans e.g. antibacterial and antiparasitic treatments. The National Residues Control Plan (NRCP) sets out the monitoring requirements for residues in animal products in accordance with Official Control Regulation 2017/625 and Annexes of Council Directive 96/23/EC of 29 April 1996 on measures to monitor certain substances and residues thereof in animals and animal products. Under EU legislation (Article 19 of Official Control Regulation (EU) 2017/625, each member state is required to implement a residue monitoring plan and to submit their programmes annually to the European Commission for approval. Ireland’s National Residue Control Programme (NRCP) for 2020 was approved by the European Commission. On behalf of the Department of Agriculture, Food and Marine (DAFM), the Marine Institute carries out monitoring of chemical residues for aquaculture. The main objectives of the NRCP for Aquaculture are to ensure farmed fish are fit for human consumption, to provide a body of data showing that Irish farmed fish is of high quality, to promote good practices in aquaculture and to comply with Official Control Regulation 2017/625 and Annexes of EU Directive 96/23/EC. In 2020, in excess of 626 tests and a total of 1,888 measurements were carried out on 120 samples of farmed finfish for a range of residues. Implementation of the Aquaculture 2020 Plan involves taking samples at both farm and processing plant: * 80 target samples taken at harvest: 70 farmed salmon and 10 freshwater trout. * 40 target samples were taken at other stages of production: 30 salmon smolts and 10 freshwater trout. All 2020 samples were compliant. For target sampling of farmed fish, a summary table of the residue results from 2005 - 2020 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 2020.

    • Newport Research Facility, Annual Report No. 65, 2020

      Marine Institute (Marine Institute, 2021)
      This report represents a continuation of the scientific aspects of the Annual Reports published by the Salmon Research Agency of Ireland, now integrated into the Fisheries Ecosystem Advisory Services Group (FEAS) of the Marine Institute. The data presented creates a unique record of fish rearing and wild fish census data for the past 49 years. This data is an essential component in the local, regional and national management of salmon, sea trout and eel and is becoming ever more valuable in the light of increasing pressures on natural stocks, such as exploitation, habitat degradation and global climate change scenarios. The fish monitoring facilities in Newport, along with the reared and ranched salmon stocks held in Burrishoole, are also essential for supporting projects such as development of novel enhancement techniques, alternative stocks and ranching and evaluation of interactions between farmed, ranched and wild strains. An expanding programme in the Burrishoole system is including ecological and genetics research into eel, sticklebacks and stock dynamics of juvenile salmonids and eels.
    • The Labadie, Jones and Cockburn Banks Nephrops Grounds (FU2021) 2021 UWTV Survey Report and catch scenarios for 2022.

      Doyle, Jennifer; Ryan, G.; Aristegui, M.; Fitzgerald, Ross; Tully, D.; O'Brien, S.; White, Jonathan; Sullivan, M.; Lynch, Deirdre; McAuliffe, M (Marine Institute, 2021)
      This report provides the main results of the 2021 underwater television survey on the ‘Labadie, Jones and Cockburn Banks’ ICES assessment area; Functional Unit 2021. The 2021 survey was multi-disciplinary in nature collecting UWTV and other ecosystem data. A total of 97 UWTV stations were completed at 6 nm intervals over a randomised isometric grid design. The mean burrow density was 0.12 burrows/m2 compared with 0.102 burrows/m2 in 2020. The 2021 geostatistical abundance estimate was 1202 million, a 18% increase on the abundance from 2020, 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 2021 estimate of abundance and updated stock data implies catch in 2022 that correspond to the ICES MSY approach of 1978 tonnes assuming that discard rates and fishery selection patterns do not change from the average of 2018–2020. One species of sea-pen (Virgularia mirabilis) were recorded as present at the stations surveyed. Trawl marks were observed at 21% of the stations surveyed.

      This report provides the main results and findings of the sixteenth 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 42 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 7%, was well below the upper limit of 20% recommended by SGNEPS (ICES, 2012). The 2021 abundance estimate was 13% lower than in 2020 and at 656 million is below the MSY Btrigger reference point (990 million). Using the 2021 estimate of abundance and updated stock data implies catch in 2022 that correspond to the ICES MSY approach of 1257 tonnes assuming that discard rates and fishery selection patterns do not change from the average of 2018–2020. One species of sea pen was recorded as present at the stations surveyed: Virgularia mirabilis. Trawl marks were observed at 24% of the stations surveyed.
    • FU19 Nephrops Grounds 2021 UWTV Survey Report and catch scenarios for 2022

      Doyle, Jennifer; Ryan, G; Aristegui, M.; Fitzgerald, Ross; Tully, D.; O’Brien, S.; White, Jonathan; Sullivan, M.; Lynch, Deirdre; McAuliffe, M (Marine Institute, 2021)
      This report provides the main results of the twelfth underwater television survey of the various Nephrops patches in Functional Unit 19. The survey was multi-disciplinary in nature collecting UWTV and other ecosystem data. In 2021 a total 42 UWTV stations were successfully completed. The mean density estimates varied considerably across the different patches. The 2021 raised abundance estimate was a 16% decrease from the 2020 estimate and at 270 million burrows is below the MSY Btrigger reference point (430 million). Using the 2021 estimate of abundance and updated stock data implies catch in 2022 that correspond to the F ranges in the EU multi annual plan for Western Waters are between 363 and 407 tonnes (assuming that discard rates and fishery selection patterns do not change from the average of 2018–2020). One species of sea pen were observed; Virgularia mirabilis which has been observed on previous surveys of FU19. Trawl marks were observed at 19% of the stations surveyed.
    • Aran, Galway Bay and Slyne Head Nephrops Grounds (FU17) 2021UWTV Survey Report and catch scenarios for 2022

      Aristegui, M.; Doyle, J.; Ryan, G.; Fitzgerald, R.; White, Jonathan; O’ Brien, S.; Tully, D.; Sullivan, M. (Marine Institute, 2021)
      This report provides the main results and findings of the twentieth 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 2021 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 2021, adjusted for edge effect, was medium at 0.26 burrows/m². The final krigged burrow abundance estimate for the Aran Grounds was 311 million burrows with a CV (Coefficient of Variance; relative standard error) of 4%. The final abundance estimate for Galway Bay was 12 million and for Slyne Head was 9 million, with CVs of 2% and 2% respectively. The total abundance estimates have fluctuated considerably over the time series. The 2021 combined abundance estimate (331 million burrows) is 16% lower than in 2020, the MSY Btrigger reference and it is below point (540 million burrows). Using the 2021 estimate of abundance and updated stock data imply that catches in 2022 should be no more than 360 tonnes, according to the EU MAP and ICES MSY approach and assuming that discard rates and fishery selection patterns do not change from the average of 2018–2020. Virgularia mirabilis was the only sea-pen species observed on the UWTV footage. Trawl marks were present at 5% of the Aran stations surveyed.
    • Western European Shelf Pelagic Acoustic Survey (WESPAS), 09 June –20 July, 2021

      O’Donnell, Ciaran; O’Malley, M.; Mullins, E; Connaughton, P.; Keogh, Niall; judge, Justin; Croot, P. (Marine Institute, 2021)
      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 to the north and west of Ireland from 53°30’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 2021. 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 2022.

      Aristegui, M.; Blaszkowski, M.; Doyle, Jennifer; O'Brien, S.; Hehir, Imelda; Bentley, K.; Fitzgerald, Ross (Marine Institute, 2021)
      This report provides the results of the ninth 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 71 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 2021, adjusted for edge effect, was 0.14 burrows/m². The final krigged abundance estimate was 1018 million burrows with a CV of 5% and an estimated stock area of 7,130 km2. The 2021 abundance estimate was 19% lower than in 2020. Using the 2021 estimate of abundance and updated stock data imply that catches in 2022 should be no more than 2804 tonnes, according to the EU MAP and ICES MSY approach (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 38% of the stations surveyed.
    • Fish Health Unit Report of Activities Undertaken in 2020

      Doré, B.; Power, Ayesha; Kenny, E.; Bradley, F.; O’ Kane, Patricia; Cheslett, D.; White, S.; Swords, Fiona (Marine Institute, 2021)
      This report summarises the activities undertaken by the Fish Health Unit (FHU) of the Marine Institute (MI) in 2020. The services of the FHU, undertaken on behalf of the State, are largely driven by European and national legislation on aquatic animal health. In 2020, animal health requirements for aquaculture animals and rules for the control of aquatic animal health within the European Union (EU) was determined in Council Directive 2006/88/EC on animal health requirements for aquaculture animals lays down rules for the control of aquatic animal health within the EU. Council Directive 2006/88/EC was enacted in Irish Law by Statutory Instrument (SI) 261 of 2008. New Animal Health Law, Regulation (EU) 2016/429 and associated implementing regulations, replaced the regulatory framework provided by Directive 2006/88/EC in April 2021. However, this report covers FHU activities carried out in 2020 under Directive 2006/88/EC and associated national legislation. The MI is the Competent Authority (CA) responsible for implementation of aquatic animal health regulation in Ireland as described in these statutes.
