    • Western European Shelf Pelagic Acoustic Survey (WESPAS) 10 June – 24 July, 2018

      O'Donnell, C.; O’Malley, M.; Lynch, D.; Mullins, E.; Keogh, N.; Power, J.; Long, A.; Croot, P. (Marine Institute, 2018)
      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 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 and since then have been carried out onboard the RV Celtic Explorer over a 42 day period providing synoptic coverage of shelf waters from 47°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 2018. 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 2019.
    • Porcupine Bank Nephrops Grounds (FU16) 2018 UWTV Survey Report and catch scenarios for 2019

      Doyle, J.; O'Brien, S.; Ryan, G.; Galligan, S.; Hernon, P.; Aristegui, M.; Vacherot, J.P.; Lordan, C. (Marine Institute, 2018)
      This report provides the results of the sixth underwater television on the ‘Porcupine Bank Nephrops grounds’ ICES assessment area; Functional Unit 16. The survey was multi-disciplinary in nature collecting UWTV, CTD and other ecosystem data. In total 69 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 2018, adjusted for edge effect, was 0.16 burrows/m². The final krigged abundance estimate was 1117 million burrows with a relative standard error of 4% and an estimated stock area of 7,130 km2. The 2018 abundance estimate was 31% higher than in 2017. Using the 2018 estimate of abundance and updated stock data implies catch of 2,645 tonnes and landings of 2,645 tonnes in 2019 when MSY approach is applied (assuming that all catch is landed). The three species of sea-pen; Virgularia mirabilis, Funiculina quadrangularis and Pennatula phosphorea, were all observed during the survey. The deepwater sea-pen Kophobelemnon stelliferum was also observed and its presence/absence mapped from the available time-series. Trawl marks were also observed on 33% of the stations surveyed.
    • Western Irish Sea Nephrops Grounds (FU15) 2018 UWTV Survey Report and catch options for 2019

      Clements, A.; Butler, R.; Doyle, J.; Ourens, R.; Lordan, C.; McCorriston, P.; Burns, G.; McCausland, I.; Erskine, K.; Lilley, K.; Heaney, G.; Lundy, M.; Schön, P.J. (Marine Institute, 2018)
      This report provides the main results and findings of the 16th annual underwater television survey on the ‘Irish sea west Nephrops grounds’ ICES assessment area, Functional Unit 15. The survey was multi-disciplinary in nature collecting UWTV and other ecosystem data. The 2018 design consisted of a randomised isometric grid of 100 stations at 4.5 nautical mile intervals out over the full known extent the stock. The resulting krigged burrow abundance estimate was 4.9 billion burrows. This was a similar result of that obtained in 2011, and 9% lower than the abundance in 2017. In contrast to 2017 the spatial distribution of burrows appears more homogenous across the survey area, with high densities in the SW of the ground in shallower water, and higher densities in the NW of the ground in deep water. Overall densities are high and abundance remains stable, well above MSY Btrigger. Reducing the number of stations compared to 2011 has not affected the accuracy of the survey estimate to date. The CV (or relative standard error) of 3% is in line with previous estimates and well below the upper limit of 20% recommended by SGNEPS 2012. Total catches and landings options at various different fishing mortalities were calculated and fishing at Fmsy in 2018 implies a total catch option at Fmsy (=Fmax) of 11,107 tonnes which results in landings of no more than 8,959 tonnes. The sea-pen species observed in 2018 was predominantly Virgularia mirabilis, with one potential observation of Pennatula phosphorea (which requires verification). Sea-pens were observed at 20% of stations with high densities observed in the south-west of the ground. Trawl marks were noted at 26% of the UWTV stations.
    • The Labadie, Jones and Cockburn Banks Nephrops Grounds (FU20-21) 2018 UWTV Survey Report and catch scenarios for 2019.

      Doyle, J.; Aristegui, M.; Hannify, O.; White, J.; Fee, D.; McCorriston, P. (Marine Institute, 2018)
      This report provides the main results of the 2018 underwater television survey on the ‘Labadie, Jones and Cockburn Banks’ ICES assessment area; Functional Unit 20-21. This was the fifth survey to achieve full coverage of the full area. The 2018 survey was multidisciplinary in nature collecting UWTV, and other ecosystem data. A total of 96 UWTV stations were completed at 6 nm intervals over a randomised isometric grid design. The mean burrow density was 0.27 burrows/m2 compared with 0.44 burrows/m2 in 2017. The 2018 geostatistical abundance estimate was 2.7±0.006 billion, a 39% decrease on the abundance for 2017, with a CV of 4% which is well below the upper limit of 20% recommended by SGNEPS 2012. High densities were observed throughout the ground, and also close to boundaries. Using the 2018 abundance estimate and updated stock data implies catch of 5,320 t and landings of 4,325 t in 2019 when MSY approach is applied (assuming that discard rates and fishery selection patterns do not change from the average of 2015–2017). One species of sea-pen (Virgularia mirabilis) were recorded as present at the stations surveyed. Trawl marks were observed at 33% of the stations surveyed.
    • The “Smalls” Nephrops Grounds (FU22) 2018 UWTV Survey Report and catch scenarios for 2019.

      Aristegui, M.; O’ Brien, S.; Blaszkowski, M.; O’Connor, S.; Fitzgerald, R.; Doyle, J. (Marine Institute, 2018)
      This report provides the main results and findings of the thirteenth annual underwater television survey on the ‘Smalls grounds’ ICES assessment area; Functional Unit 22. The survey was multi-disciplinary in nature collecting UWTV, CTD and other ecosystem data. A total of 42 UWTV stations were surveyed successfully (good quality video footage), carried out over an isometric grid at 4.5nmi or 8.3km intervals. The precision, with a CV of 9%, was well below the upper limit of 20% recommended by SGNEPS (ICES, 2012). The 2018 abundance estimate was 45% lower than in 2017 and at 876 million is below the MSY Btrigger reference point (990 million). Using the 2018 estimate of abundance and updated stock data implies catch of 2,084 tonnes and landings of 1,780 tonnes in 2019 when the MSY approach is applied (assuming that discard rates and fishery selection patterns do not change from the average of 2015–2017). Two species of sea pens were recorded as present at the stations surveyed: Virgularia mirabilis and Pennatula phosphorea. Trawl marks were observed at 55% of the stations surveyed. Nine beam trawl tows were carried out, providing important data on the benthic communities and size structure of the Nephrops population.
    • FU19 Nephrops grounds 2018 UWTV survey report and catch scenarios for 2019.

      Aristegui, M.; O’Brien, S.; Blaszkowski, M.; O’Connor, S.; Fitzgerald, R.; Doyle, J. (Marine Institute, 2018)
      This report provides the main results of the ninth underwater television survey of the various Nephrops patches in Functional Unit 19. The survey was multidisciplinary in nature collecting UWTV, multi-beam and other ecosystem data. In 2018 a total 42 UWTV stations were successfully completed. The mean density estimates varied considerably across the different patches. The 2018 raised abundance estimate was a 65% decrease from the 2017 estimate and at 176 million burrows is below the MSY Btrigger (430 million). Using the 2018 estimate of abundance and updated stock data implies catch of 173 tonnes and landings of 130 tonnes in 2018 when MSY approach is applied (assuming that discard rates and fishery selection patterns do not change from the average of 2015–2017). One species of sea pen was observed; Virgularia mirabilis, which has been observed on previous surveys of FU19. Trawl marks were observed at 36% of the stations surveyed.
    • Aran, Galway Bay and Slyne Head Nephrops Grounds (FU17) 2018 UWTV Survey Report and catch scenarios for 2019

      Doyle, J.; O’ Brien, S.; Ryan, G.; Galligan, S.; Hernon, P.; Aristegui, M.; Vacherot, J.P. (Marine Institute, 2018)
      This report provides the main results and findings of the seventeenth annual underwater television 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, fishing, CTD and other ecosystem data. In 2018 a total of 43 UWTV stations were successfully completed, 33 on the Aran Grounds, 5 on Galway Bay and 5 on Slyne Head patches. The mean burrow density observed in 2018, adjusted for edge effect, was medium at 0.40 burrows/m². The final krigged burrow abundance estimate for the Aran Grounds was 488 million burrows with a CV (relative standard error) of 3%. The final abundance estimate for Galway Bay and Slyne Head was 33 million in both grounds with CVs of 17% and 12% respectively. The total abundance estimates have fluctuated considerably over the time series. The 2018 combined abundance estimate was a 37% increase compared to in 2017 and at 554 million burrows and is above the MSY Btrigger reference point (540 million burrows). Using the 2018 abundance estimate and updated stock data implies catch of 1002 tonnes and landings of 916 tonnes in 2019 when the MSY approach is applied (assuming that discard rates and fishery selection patterns do not change from the average of 2015–2017). Virgularia mirabilis was the only sea-pen species observed on the UWTV footage. Trawl marks were present at 9% of the Aran stations surveyed.

    • The drivers of sea lice management policies and how best to integrate them into a risk management strategy: An ecosystem approach to sea lice management.

      Jackson, D; Moberg, O; Stenevik Djupevåg, E M; Kane, F; Hareide, H (John Wiley & Sons Ltd, 2018)
      The control of sea lice infestations on cultivated Atlantic salmon is a major issue in many regions of the world. The numerous drivers which shape the priorities and objectives of the control strategies vary for different regions/jurisdictions. These range from the animal welfare and economic priorities of the producers, to the mitigation of any potential impacts on wild stocks. Veterinary ethics, environmental impacts of therapeutants, and impacts for organic certification of the produce are, amongst others, additional sets of factors which should be considered. Current best practice in both EU and international environmental law advocates a holistic ecosystem approach to assessment of impacts and risks. The issues of biosecurity and ethics, including the impacts on the stocks of species used as cleaner fish, are areas for inclusion in such a holistic ecosystem assessment. The Drivers, Pressures, State, Impacts, Responses (DPSIR) process is examined as a decision-making framework and potential applications to sea lice management are outlined. It is argued that this is required to underpin any integrated sea lice management (ISLM) strategy to balance pressures and outcomes and ensure a holistic approach to managing the issue of sea lice infestations on farmed stock on a medium to long-term basis.
    • Marine Biotechnology Task Force Report

      Marine Biotechnology Task (Marine Institute, 2017)
      Marine biotechnology is a rapidly growing area that is recognised, by policy makers and the enterprise sector, as offering significant potential to develop market opportunities for new products and processes by enabling greater utilisation of marine biological resources. Current research funding activity, supporting efforts to create a sustainable bioeconomy, is likely to lead to a growth in marine biotechnology research and commercial activities. Irish and international financial support for this research is aimed at as yet largely unexplored and underexploited marine resources for use as food, functional foods and nutraceuticals; cosmetics and cosmeceuticals; human and animal health – including pharmaceuticals, biocompatible materials and medical devices; materials technology; environmental bioremediation; and marine model organisms, including the use of marine derived materials in bioprocessing. Research within these areas has resulted in an array of new products and processes which offer benefits to society and support economic growth. The Marine Institute established a Task Force to advise on the steps required to strengthen Ireland’s capability to use marine biotechnology to exploit the value of its extensive marine bioresources. The Task Force, comprising academic and industry members, considered the various national strategies and plans for science, technology, research and economic development, and identified market opportunity areas and Irish marine biotechnology research capabilities. In supporting the work of the Task Force, the Marine Institute completed a number of information-gathering exercises to fill various knowledge gaps identified by the Task Force. Following the preparation of a draft report, the Task Force, with the support of the Marine Institute, held a workshop attended by researchers and companies. This final report of the Task Force takes account of feedback from this workshop in developing its recommendations.

    • Science: 5th and 6th Class: Build your own seismometer – learning about forces under the sea

      Marine Institute (Marine Institute, 2018)
      Earthquakes occur when parts of the Earth’s crust and upper mantle move suddenly. Large earthquakes can cause catastrophic amounts of damage so it’s very important to be able to predict when they might happen. Earthquakes are detected using a seismometer which detects vibrations in the earth. In class, groups of students can work together to make a simple model of a seismometer to demonstrate how they work. The students will experience working in groups and through a creative process develop skills intrinsic to working scientifically
